Motorcycle Lane-Splitting Laws in All 50 U.S. States (2025)

tl;dr: California, Montana, Arizona and Utah are the only states where some form of lane splitting or lane filtering are allowed. 

Motorcycle lane splitting (riding between lanes of traffic) and lane filtering (moving between stopped or slow cars) are regulated at the state level. Below is an overview for each state, including whether the practice is legal, illegal, or not addressed, with citations of the governing statutes or rules. In general, most states explicitly prohibit lane splitting. Only a few states permit it under specific conditions, and California is unique in broadly allowing it. Each state description cites the relevant law (from official state sources) and any notable details or exceptions.

Alabama

Alabama law prohibits lane splitting. Alabama Code § 32-5A-242 entitles motorcycles to full use of a lane and explicitly states that “[n]o person shall operate a motorcycle between lanes of traffic or between adjacent lines or rows of vehicles.”​ law.onecle.com Riding two abreast in a single lane is allowed, but a motorcycle may not overtake a vehicle in the same lane. The only exception is for on-duty police officers. In short, lane splitting and filtering are not permitted in Alabama, and violators can be ticketed under this statute.

Alaska

Alaska does not allow lane splitting. Alaska’s traffic laws grant motorcycles the same full-lane rights as other vehicles and do not authorize riding between lanes. Although Alaska’s statutes do not appear to contain a specific “lane splitting” clause by name, the practice would violate general safe-driving rules (such as improper passing). Like many states, Alaska follows the standard that a motorcycle “is entitled to full use of a lane” and cannot overtake a vehicle within the same lane or ride between lanes. In practice, lane splitting is treated as illegal in Alaska (e.g. as an unsafe or improper pass) under the state’s uniform traffic code provisions​ codes.findlaw.com​ codes.findlaw.com. No statute or regulation explicitly permits it, so riders who lane split can be cited.

Arizona

Arizona allows lane filtering (a limited form of lane splitting) under specific conditions as of 2022. Prior to that, Arizona law (A.R.S. § 28-903) expressly banned lane splitting (identical to the uniform rule found in other states). In 2022, Arizona revised its law via S.B. 1273. Now, A.R.S. § 28-903(F) permits a two-wheeled motorcycle to overtake stopped vehicles and travel between lanes if all of the following conditions are met: the road has at least two lanes in the same direction, the posted speed limit is 45 mph or less, traffic is stopped, and the motorcycle moves at 15 mph or below​ azleg.gov​ azleg.gov. This essentially legalizes lane filtering on congested urban streets. Outside of these conditions, traditional lane splitting at higher speeds or in moving traffic remains illegal (A.R.S. § 28-903(C) still forbids riding between lanes in general)​ law.onecle.com.

Arkansas

Arkansas law prohibits lane splitting. Under Ark. Code Ann. § 27-51-302, motorcycles are entitled to full use of a traffic lane, and it is unlawful to deprive a motorcycle of that full lane or for a motorcycle operator to overtake/pass another vehicle within the same lane. The statute also states that no person shall operate a motorcycle between adjacent lines or rows of vehicles (which is the definition of lane splitting). Like other states, Arkansas allows no more than two motorcycles side by side in one lane, but explicitly forbids filtering between cars. In summary, lane splitting is not legal in Arkansas; a motorcyclist must remain in a single lane when passing (except when fully changing lanes to overtake). Violations can be cited under the above statute​ codes.findlaw.com​  codes.findlaw.com.

California

California is the only state that broadly permits lane splitting. In 2016, California added §21658.1 to its Vehicle Code, formally defining “lane splitting” and empowering the California Highway Patrol to establish safety guidelines​ chp.ca.gov​ chp.ca.gov. California Vehicle Code §21658.1 defines lane splitting as a motorcycle riding between rows of stopped or moving vehicles, and as of January 1, 2017, the practice is legally recognized​ chp.ca.gov. The law itself does not set specific speed limits for splitting, but CHP’s guidelines advise it be done at safe speeds (generally ≤10 mph faster than traffic, and only when traffic is 30 mph or below). The CHP explicitly notes: “Lane splitting by motorcyclists is legal in California.”​ chp.ca.gov However, unsafe lane splitting (at high speed differentials or in dangerous conditions) can still be cited under California’s general unsafe driving laws. Overall, California endorses responsible lane splitting, unlike any other state.

Colorado

Colorado prohibits lane splitting. Colorado’s statutes (e.g. Colo. Rev. Stat. § 42-4-1503) grant motorcycles full use of a lane and forbid passing or overtaking a vehicle in the same lane. Riding between lanes of traffic (lane splitting) is not allowed ​codes.findlaw.com​ codes.findlaw.com. Motorcycles may not travel more than two abreast in a single lane either. As of 2025, Colorado was considering legislation to allow limited lane filtering (e.g. 2024’s SB 79 ​landline.media), but unless such a law passes, lane splitting remains illegal. Any motorcyclist attempting to split lanes in Colorado can be ticketed for improper passing or lane usage under current law.

Connecticut

Connecticut law does not permit lane splitting. Connecticut General Statutes § 14-289 (and related provisions) effectively require motorcycles to adhere to the same lane rules as other vehicles. Connecticut entitles motorcycles to a full lane and prohibits them from overtaking a car in the same lane or riding between lanes of traffic. Although Connecticut’s statutes don’t use the phrase “lane splitting,” the practice falls under unsafe passing or following too closely, and law enforcement treats it as illegal. In short, a motorcyclist in Connecticut must fully change lanes to pass another vehicle – straddling lanes or filtering between cars is not allowed​ codes.findlaw.com ​codes.findlaw.com. Violators could be cited for failing to maintain lane or unsafe passing.

Delaware

Delaware bans lane splitting by statute. Title 21 of the Delaware Code includes provisions (similar to the uniform motorcycle rules) stating that motorcycles have the right to a full lane and may not overtake another vehicle in the same lane. Delaware law also explicitly bars operating a motorcycle between adjacent lanes or rows of vehicles. Thus, lane splitting or filtering is illegal in Delaware. Motorcycles can ride two abreast in one lane (with another motorcycle), but they cannot share lanes with cars or use the gaps between lines of traffic​ codes.findlaw.com​ codes.findlaw.com. Any such maneuver would violate Delaware’s traffic code (likely falling under improper passing or lane usage statutes) and result in a citation.

Florida

Florida prohibits lane splitting. Florida Statutes § 316.209 (“Operating motorcycles on roadways laned for traffic”) gives motorcycles the full use of a lane and explicitly forbids two key behaviors: a motorcycle operator may not overtake/pass another vehicle in the same lane, and “no person shall operate a motorcycle between lanes of traffic or between adjacent lines or rows of vehicles.” ​law.justia.com​ law.justia.com This language in Florida law clearly outlaws lane splitting and lane filtering. Florida does allow motorcycles to ride two abreast in a lane (two motorcycles side by side), but a motorcycle cannot share a lane with a car except when fully changing lanes. In summary, lane splitting is illegal in Florida and can be cited as a moving violation.

Georgia

Georgia law bans lane splitting. O.C.G.A. § 40-6-312 governs motorcycle operation on laned roadways and is very clear: “The operator of a motorcycle shall not overtake and pass in the same lane occupied by the vehicle being overtaken” and “No person shall operate a motorcycle between lanes of traffic or between adjacent lines or rows of vehicles.”​ law.justia.com​ law.justia.com. This Georgia statute also affirms that motorcycles are entitled to full use of a lane, and it limits motorcycles to two abreast in one lane. In practice, this means a biker in Georgia must fully change lanes to pass another vehicle. Lane splitting or filtering (riding between cars in stopped or moving traffic) is unlawful. Georgia riders caught lane splitting can be ticketed under §40-6-312.

Hawaii

Hawaii prohibits lane splitting. Under HRS § 291C-153, motorcycles cannot lane split or lane share – Hawaii law mirrors the standard rule that a motorcycle may not pass another vehicle in the same lane or drive between lanes of traffic​ hidot.hawaii.gov. (Two motorcycles may ride side by side in one lane, but that is the only exception to full lane usage.) Notably, Hawaii experimented with a shoulder usage program: a 2018 law (Act 218) temporarily allowed motorcycles to use designated highway shoulders in congested conditions ​hidot.hawaii.gov. That pilot program expired at the end of 2020 and was not extended. As of 2025, lane splitting and shoulder riding are not legal in Hawaii ​hidot.hawaii.gov​ hidot.hawaii.gov. Hawaii DOT explicitly reminds riders that they may not ride on the shoulder or between lanes, and violators can be cited.

Idaho

Idaho does not allow lane splitting. Idaho Code requires motorcycles to stay within their lane when overtaking vehicles. Although Idaho has no special statute overtly titled “lane splitting,” the practice falls under improper overtaking. Idaho law (similar to UVC 11-1303) grants motorcycles full lane rights and says they may not pass another vehicle in the same lane or ride between lanes of traffic​ codes.findlaw.com​ codes.findlaw.com. In other words, a motorcycle must use an adjacent lane to overtake. Lane filtering between stopped cars is also not authorized. Idaho has considered lane filtering proposals in the past, but as of 2025 none have been enacted. Therefore, lane splitting is treated as illegal in Idaho, and police can cite riders for violating lane discipline or safe passing laws.

Illinois

Illinois forbids lane splitting. The Illinois Vehicle Code (625 ILCS 5/11-703 and 5/11-711) contains the standard language: motorcycles are entitled to full use of a lane, and it is illegal for a motorcycle to pass a vehicle in the same lane or to travel between lanes of traffic. Illinois does not have any exception allowing lane filtering – a motorcycle must merge fully into another lane to pass. The Illinois Secretary of State’s motorcycle handbook also emphasizes that lane sharing (with cars) is not permitted. In short, lane splitting or riding between lanes is not legal in Illinois​ codes.findlaw.com ​codes.findlaw.com, and doing so violates Illinois traffic statutes.

Indiana

Indiana law prohibits lane splitting. Indiana Code § 9-21-10-6 states that motorcyclists may not overtake or pass in the same lane occupied by the vehicle being overtaken, and § 9-21-10-7 adds that “a motorcycle may not be operated between lanes of traffic or between adjacent lines or rows of vehicles” (except for on-duty police) – effectively banning lane splitting ​codes.findlaw.com​ codes.findlaw.com. Indiana does allow two motorcycles to ride side by side in one lane (IC 9-21-10-6(b)), but a motorcycle cannot share a lane with a car except by fully changing lanes. The bottom line: lane splitting is illegal in Indiana, and a rider doing it can be cited for violating the above statutes.

Iowa

Iowa does not permit lane splitting. Iowa Code § 321.275 covers motorcycle operations and stipulates that a motorcycle is entitled to full use of a lane. It forbids a motorcycle from passing another vehicle in the same lane and from operating between lanes or rows of vehicles. Thus, lane splitting is explicitly illegal. Iowa, like other states, only allows two motorcycles side by side in one lane (no other lane sharing). In 2022, Iowa considered a bill to allow some form of lane filtering, but as of 2025 no such law has been adopted. Therefore, motorcyclists in Iowa must not lane split; doing so would violate §321.275 and result in a traffic violation.

Kansas

Kansas bans lane splitting. Kansas Statutes (K.S.A. 8-1596) contain the standard provisions: a motorcycle cannot overtake a car in the same lane and cannot operate between lanes of traffic. Motorcycles have the right to a full lane, and other vehicles must not crowd them. Kansas allows no more than two motorcycles side by side per lane. There is no exception in Kansas law for filtering through stopped traffic, so any form of lane splitting or lane sharing with cars is unlawful​ codes.findlaw.com​ codes.findlaw.com. Kansas has not passed any recent legislation to change this. Riders who attempt to lane split in Kansas can be cited for improper passing/lane usage under K.S.A. 8-1596.

Kentucky

Kentucky law prohibits lane splitting. KRS § 189.285(3) explicitly states that “no operator shall pass another vehicle within the same lane or drive a motorcycle between lanes of traffic” (paraphrased). Kentucky gives motorcycles full use of the lane (KRS 189.285(1)) and, like other states, only allows two motorcycles to a lane abreast. The Kentucky State Police and transportation cabinet make clear that lane splitting or filtering is not legal. Thus, a motorcyclist in Kentucky must stay in one lane when passing and may not weave between cars. Any violation can result in a citation under KRS 189.285 for improper operation of a motorcycle.

Louisiana

Louisiana does not allow lane splitting. Louisiana Revised Statutes Title 32:191.1 provides that motorcycles have the right to a full lane and shall not be driven between lanes of traffic. The law in Louisiana mirrors the common rule: no passing in the same lane as another vehicle and no riding between rows of cars​ codes.findlaw.com​ codes.findlaw.com. Two motorcycles may travel side by side in one lane (with consent), but a motorcycle may not share a lane with a car except by fully changing lanes. Louisiana has no special provision to permit lane filtering, so the practice remains illegal. Motorcyclists lane splitting in Louisiana can be ticketed for violating R.S. 32:191.1.

Maine

Maine prohibits lane splitting. Title 29-A M.R.S. § 2062 covers motorcycle operating rules. Maine law grants motorcycles full use of a lane and specifically forbids passing a vehicle in the same lane or operating between lanes of traffic (except for on-duty police officers). Therefore, lane splitting or filtering is illegal in Maine. Like other states, Maine allows no more than two motorcycles side by side per lane. There have been no changes to Maine law to allow lane splitting as of 2025. Motorcyclists must abide by normal lane-change rules when overtaking. Any attempt to lane split could be cited under §2062 as an improper manner of operation​ codes.findlaw.com​ codes.findlaw.com.

Maryland

Maryland does not permit lane splitting. Maryland Transportation Code § 21-1303 lays out that motorcycles are entitled to use a full lane and shall not be driven in a way that deprives another vehicle of a full lane. It also says a motorcyclist may not overtake a vehicle in the same lane and may not operate a motorcycle between lanes of traffic (lane splitting)​ codes.findlaw.com ​codes.findlaw.com. Maryland strictly enforces this – riders must fully change lanes to pass other vehicles. Maryland DOT and State Police advise that lane splitting is unsafe and illegal. No part of Maryland law authorizes lane filtering, so any such maneuver violates §21-1303 and can result in a citation.

Massachusetts

Massachusetts bans lane splitting. Mass. General Laws c.90 § 13 and related regulations require motor vehicles (including motorcycles) to stay within marked lanes. Massachusetts also adopts the common rule (through statute or CMR regulations) that a motorcycle cannot share a lane with a car except by overtaking in a separate lane. While the Massachusetts law may not use the exact words “lane splitting,” in practice it is considered illegal – the Registry of Motor Vehicles and safety guides make clear that riding between lanes or between vehicles is not allowed. Massachusetts permits two motorcycles side by side in a lane (c.90 § 4A), but prohibits lane splitting or filtering. A motorcyclist doing so could be cited under the general marked lanes law or for unsafe passing.

Michigan

Michigan does not allow lane splitting. Michigan Vehicle Code (MCL 257.660) grants motorcycles full lane rights and explicitly states that “a motorcycle shall not overtake and pass in the same lane occupied by the vehicle being overtaken” and that no motorcycle shall be operated between lanes of traffic​ codes.findlaw.com​ codes.findlaw.com. These provisions make lane splitting illegal in Michigan. Two motorcycles may ride abreast in one lane (if both consent), but a motorcycle cannot pass cars within the same lane. Michigan has not passed any law to permit lane filtering. Law enforcement will ticket riders for improper passing or lane use if they attempt to lane split in Michigan.

Minnesota

Minnesota prohibits lane splitting. Under Minnesota Statutes § 169.974, subd. 5, a motorcycle is entitled to a full lane and riders are barred from overtaking a vehicle in the same lane or from riding between lanes of traffic. The law specifically notes that motorcycles shall not be operated between adjacent lines of vehicles. Thus, lane splitting and filtering are illegal. Minnesota allows two motorcycles side by side in one lane (with consent), but no interaction with cars in the same lane. The Minnesota Driver’s Manual for motorcycles reiterates that lane splitting is against the law. Any rider attempting it can be cited under Minn. Stat. 169.974 for improper lane use.

Mississippi

Mississippi does not permit lane splitting. Mississippi Code § 63-3-1313 (part of the motorcycle operating rules) gives motorcycles full use of a lane and prohibits passing a vehicle in the same lane. It also states that no person shall operate a motorcycle between lanes of traffic. This makes lane splitting illegal in Mississippi (which was explicitly noted in an Oregon legislative analysis of state laws​ landline.media). Mississippi has not enacted any exceptions for lane filtering. Therefore, a motorcyclist must obey normal lane-change rules when overtaking. Lane splitting would be considered a traffic violation (improper passing or lane usage) under Mississippi law.

Missouri

Missouri bans lane splitting. Missouri Revised Statutes § 304.015 affirms a motorcycle’s right to a full lane and forbids lane splitting. Specifically, a motorcycle operator may not overtake a vehicle within the same lane and may not ride between lanes of traffic. Missouri does allow motorcycles to ride two abreast in one lane (two bikes side by side), but not to share lanes with cars. Recent attempts to legalize lane filtering in Missouri have not passed, so as of 2025 the practice remains unlawful. A Missouri motorcyclist who lane splits can be ticketed under §304.015 for improper lane usage. The Missouri State Highway Patrol also advises that lane splitting is unsafe and not legal.

Montana

Montana allows lane filtering (slow-speed lane splitting) under a law enacted in 2021. Prior to that, Montana followed the standard prohibition on lane splitting. Now, Montana Code Ann. § 61-8-392 permits motorcycles to filter between lanes under specific conditions. A two-wheeled motorcycle may “engage in lane filtering” when: (a) the motorcycle is on a road with lanes wide enough to pass safely, (b) traffic is stopped or traveling under 10 mph, and (c) the motorcyclist does not exceed 20 mph while filtering ​archive.legmt.gov ​archive.legmt.gov. The law defines “lane filtering” as overtaking stopped or slow (≤10 mph) vehicles in the same lane ​archive.legmt.gov. This means Montana now allows a motorcycle to slip between stopped or very slow cars, up to 20 mph, when it can be done safely. Outside of those conditions, traditional high-speed lane splitting is still illegal (Montana still prohibits passing in the same lane at regular speeds). Montana was one of the first states after California to legalize limited filtering.

Nebraska

Nebraska prohibits lane splitting. Nebraska Revised Statutes § 60-6,308 gives motorcycles full lane rights and bars them from overtaking a vehicle in the same lane or riding between lanes of traffic (except police officers on duty). Thus, lane splitting is illegal in Nebraska. Two motorcycles may ride abreast in a lane (Neb. Rev. Stat. 60-6,307), but a motorcycle cannot share a lane with a car except by changing lanes. Nebraska has not passed any law to allow lane filtering. Any motorcyclist attempting to split lanes in Nebraska would be violating §60-6,308 and could be cited for improper passing or lane use​ codes.findlaw.com ​codes.findlaw.com.

Nevada

Nevada does not allow lane splitting. Nevada Revised Statutes 486.351 explicitly provides that a motorcycle shall not overtake or pass another vehicle in the same lane and shall not be driven between moving or stationary vehicles in adjacent lanes (lane splitting is forbidden). Nevada’s law is virtually identical to the standard clause used in other states. Motorcycles are entitled to a full lane, and other vehicles must not encroach on them. Riding two motorcycles side by side in one lane is allowed in Nevada, but a motorcycle cannot split lanes with cars. As of 2025, Nevada has not legalized any form of lane filtering, so the practice remains illegal and subject to citation under NRS 486.351.

New Hampshire

New Hampshire prohibits lane splitting. New Hampshire law (RSA 265:121) on motorcycle operation specifies that no motorcycle shall be driven between lanes or rows of traffic. Motorcycles have full use of a lane in New Hampshire, and it is unlawful for a rider to pass another vehicle without fully changing lanes. New Hampshire, known for its freedom-friendly motorcycle laws in some respects (e.g. no helmet law for adults), still does not allow lane splitting – safety officials consider it dangerous. Therefore, lane splitting or filtering is illegal in New Hampshire, and a motorcyclist doing it can be ticketed for unsafe passing or lane discipline under RSA 265:121 (or general rules of the road).

New Jersey

New Jersey bans lane splitting. There is no statute in New Jersey that ever permits a motorcycle to ride between lanes – in fact, the New Jersey Motor Vehicle Code requires motorcycles to obey all lane markings just like cars. By regulation and practice, NJ considers lane splitting an unsafe lane change or improper passing. The New Jersey Driver Manual explicitly warns that lane splitting is illegal. Any rider attempting it can be stopped and cited under N.J.S.A. 39:4-88 (failure to maintain lane) or similar statutes. In short, New Jersey does not have a special law naming “lane splitting,” but it is definitely illegal under general traffic laws. Motorcycles must use a complete lane to themselves when passing other vehicles.

New Mexico

New Mexico does not permit lane splitting. New Mexico statute (NMSA 66-7-318) addresses motorcycles on laned roadways and contains the standard prohibitions: a motorcycle shall not pass in the same lane as another vehicle and shall not operate between lanes of traffic. New Mexico thus makes lane splitting unlawful. The state allows two motorcycles side by side in one lane, but no mixing of a motorcycle with cars in a lane. An analysis by the Oregon legislature specifically listed New Mexico among states that explicitly ban lane filtering ​landline.media. There have been no changes to New Mexico law to allow it, so riders must not lane split. Police can ticket violators under NMSA 66-7-318 for improper lane usage.

New York

New York prohibits lane splitting. NY Vehicle & Traffic Law § 1252 governs motorcycles and is effectively the same as the standard rule: it forbids a motorcycle from overtaking a vehicle in the same lane and from operating between lanes or rows of traffic. New York gives motorcycles full lane rights but does not allow lane sharing with cars. The NYPD and DMV enforce this strictly – lane splitting is illegal statewide (including New York City). A motorcyclist who lane splits in New York can be cited under VTL 1252(c) for improper passing. New York has not pursued any lane filtering legalization. Thus, the practice remains against the law in NY.

North Carolina

North Carolina bans lane splitting. N.C. General Statutes § 20-146.1 covers motorcycles on laned roads and clearly states that no motorcycle shall overtake/pass in the same lane as another vehicle, and “no operator shall operate a motorcycle between lanes of traffic or between adjacent lines or rows of vehicles”. This makes lane splitting illegal in NC. As usual, two motorcycles may ride side by side in one lane, but a motorcycle may not share a lane with a car except by changing lanes. North Carolina is among the states explicitly prohibiting lane filtering​ landline.media. Riders in NC must stay in one lane; any attempt to split lanes is a violation of §20-146.1 and subject to enforcement.

North Dakota

North Dakota does not allow lane splitting. North Dakota Century Code § 39-10-11 mirrors the standard language: a motorcycle is entitled to full use of a lane, and it is illegal for a motorcycle to pass another vehicle in the same lane or to ride between lanes of traffic. Therefore, lane splitting is not legal in North Dakota. No special exceptions exist for filtering in traffic jams – a motorcyclist must wait or change lanes normally. North Dakota law enforcement would cite lane splitting under §39-10-11 or under general unsafe driving statutes. In summary, ND prohibits lane splitting just as most states do​ codes.findlaw.com​ codes.findlaw.com.

Ohio

Ohio prohibits lane splitting. Ohio Revised Code § 4511.55(B) states that motorcycles are entitled to full use of a lane and no motor vehicle should deprive them of it. Further, Ohio law (often cited in rider handbooks) makes it unlawful for a motorcycle to pass another vehicle within the same lane or to weave between lanes of slow traffic. Ohio has been listed among states that explicitly ban lane filtering ​landline.media. Two motorcycles abreast in one lane are allowed in Ohio, but that’s the only lane sharing permitted. If a motorcyclist lane splits in Ohio, they can be ticketed, typically under §4511.55 or the uniform traffic rules, for improper passing.

Oklahoma

Oklahoma bans lane splitting. Oklahoma Statutes Title 47, § 11-1103 contains the standard motorcycle lane rule: “No person shall operate a motorcycle between lanes of traffic or between adjacent lines or rows of vehicles,” and a motorcycle shall not pass another vehicle in the same lane. Oklahoma law affords motorcycles full lane use and prohibits lane splitting or filtering. Riding two abreast in a lane is permitted for motorcycles in OK, but that’s the only exception. Oklahoma was explicitly mentioned as prohibiting lane filtering ​landline.media. Accordingly, lane splitting is illegal in Oklahoma, and any rider doing so violates §11-1103 and can be cited by law enforcement.

Oregon

Oregon (as of 2025) prohibits lane splitting, though the state has been actively debating a change. Current Oregon law (ORS § 814.240) classifies lane splitting as “unlawful passing in a lane.” A motorcycle operator may not pass a vehicle in the same lane unless that vehicle is another motorcycle or moped​ oregon.public.law. Operating a motorcycle between lanes of traffic is illegal. In recent years, Oregon has introduced legislation to allow limited lane filtering (for example, 2021’s SB 574 and 2023’s HB 3542), but those bills had not become law by 2025. Until a new law is enacted, Oregon riders must not lane split. It remains citable as a traffic offense (ORS 814.240) if a motorcyclist tries to filter between cars.

Pennsylvania

Pennsylvania does not allow lane splitting. 75 Pa. C.S. § 3523 sets forth Pennsylvania’s rules for motorcycles on laned roadways. It explicitly prohibits a motorcycle from overtaking a vehicle in the same lane and from operating between lanes or rows of traffic. Pennsylvania, like other states, only allows two motorcycles side by side in one lane. The Pennsylvania DOT and motorcycle operator manual reinforce that lane splitting is illegal. Attempts in the legislature to study lane splitting have not led to any change in the law. Therefore, lane splitting or filtering is unlawful in Pennsylvania, and a violator can be cited under §3523 for improper passing.

Rhode Island

Rhode Island prohibits lane splitting. Rhode Island General Laws § 31-10.1-4 and § 31-15-12 (covering motorcycle operation) give motorcycles the right to a full lane and bar them from overtaking another vehicle in the same lane. Riding between lanes of traffic is not permitted. Rhode Island does not have any exception or pilot program allowing lane filtering. Motorcycles must abide by normal passing rules – use an adjacent lane or wait. Lane splitting in Rhode Island would violate the above statutes and likely be cited as such. In summary, Rhode Island treats lane splitting as illegal, consistent with the standard rules followed by most states​ codes.findlaw.com ​codes.findlaw.com.

South Carolina

South Carolina bans lane splitting. S.C. Code Ann. § 56-5-3640 mirrors the usual language: a motorcycle shall not overtake a vehicle in the same lane and shall not be operated between lanes or rows of traffic. South Carolina law ensures motorcycles get a full lane and prohibits splitting that lane with other vehicles (except motorcycles side by side). The South Carolina Department of Public Safety explicitly notes that lane splitting is unlawful in the state. As of 2025, no law in SC allows filtering. Thus, any form of lane splitting or sharing with cars is illegal, and a motorcyclist doing it can be ticketed under §56-5-3640.

South Dakota

South Dakota does not permit lane splitting. SDCL § 32-20-9 establishes that motorcycles have full use of a lane and that no motor vehicle may deprive them of that, and it also prohibits a motorcycle from passing another vehicle in the same lane. Additionally, South Dakota law bars operating a motorcycle between lanes of traffic. These provisions make lane splitting illegal. South Dakota, with its wide-open roads (famous for the Sturgis rally), still requires motorcycles to follow standard lane rules. No special lane filtering law exists. So lane splitting remains unlawful, and riders can be cited under SDCL 32-20-9 for any such maneuver.

Tennessee

Tennessee prohibits lane splitting. Tenn. Code Ann. § 55-8-182(c) unambiguously states: “No person shall operate a motorcycle between lanes of traffic or between adjacent lines or rows of vehicles.” Together with §55-8-182(b), which bans passing in the same lane, this makes any lane splitting or filtering illegal​ codes.findlaw.com​ codes.findlaw.com. Tennessee law does allow two motorcycles to ride side by side in one lane (55-8-182(a)), but that is the only allowed lane sharing. The Tennessee Department of Safety also instructs that lane splitting is not legal. Any rider attempting it can be pulled over and cited under these statutes. In short, Tennessee does not permit lane splitting under any circumstances.

Texas

Texas law prohibits lane splitting – though interestingly, Texas has no statute that explicitly mentions “lane splitting.” Instead, Texas enforces this via its lane discipline and passing laws. Texas Transportation Code § 545.060 requires vehicles to stay within a single lane and only move when safe to do so, effectively barring motorcycles from riding the lane lines between cars. DPS officials have consistently stated that lane splitting is illegal in Texas (viewed as unsafe lane changing or passing on the right illegally). In 2015, Texas added § 545.0605 to clarify that motorcycles can ride two abreast in one lane, but it did not legalize lane splitting ​codes.findlaw.com. Legislative attempts to explicitly allow filtering have so far failed. Thus, as of 2025, lane splitting remains illegal in Texas; a motorcyclist doing it can be cited (often under the “failure to drive in a single lane” rule of §545.060 or for unsafe passing).

Utah

Utah allows a limited form of lane splitting called lane filtering. In 2019, Utah enacted Utah Code § 41-6a-704(6), which permits motorcycles to filter between stopped vehicles under very specific conditions. A Utah motorcyclist may ride between lanes of stopped traffic only if: the roadway has at least two lanes in the same direction, the speed limit is 45 mph or less, the vehicles being overtaken are stopped, and the motorcycle is going 15 mph or less ​le.utah.gov​ le.utah.gov. All those conditions must be met – essentially, Utah allows filtering to the front of traffic at red lights on city streets. If traffic is moving above 0 mph, or if the street is high-speed, filtering is not allowed. This law was initially a pilot and made permanent due to its success. Any lane splitting outside the allowed scenario (e.g. at highway speeds) remains illegal in Utah (Utah Code § 41-6a-704(2)–(5) still require normal passing)​ le.utah.gov​ le.utah.gov. Utah Highway Patrol actively educates riders on the exact conditions of legal filtering.

Vermont

Vermont prohibits lane splitting. Vermont law (23 V.S.A. § 1038) addresses motorcycles on roadways and conforms to the standard rule: no passing or overtaking in the same lane and no operating between lanes of traffic. Vermont requires motorcycles to essentially follow car rules for lane changes. Thus, lane splitting or filtering is not allowed. Vermont has a relatively small volume of urban traffic, and there has been little push to allow splitting. As of 2025, a motorcyclist who splits lanes in Vermont is violating §1038 and can be ticketed for improper passing or laned roadway violations​ codes.findlaw.com​ codes.findlaw.com.

Virginia

Virginia bans lane splitting. Code of Virginia § 46.2-857 makes it reckless driving to overtake or pass a vehicle going in the same direction by driving off the main portion of the roadway – which has been interpreted to include lane splitting (passing within the same lane) as a form of improper passing. Additionally, Virginia traffic regulations explicitly forbid operating a motorcycle between lanes. The Virginia DMV motorcycle handbook states that lane splitting is against the law. Virginia does not allow any filtering; attempts to legalize it have failed in the General Assembly. Therefore, lane splitting in Virginia is illegal and often cited as reckless driving or improper passing under §46.2-857 (a serious offense) ​codes.findlaw.com​ codes.findlaw.com.

Washington

Washington state (as of 2025) prohibits lane splitting. RCW 46.61.608 is Washington’s motorcycle-lane law and closely follows the uniform language: a motorcycle shall not overtake/pass in the same lane occupied by another vehicle, and “no person shall operate a motorcycle between lanes of traffic or between adjacent lines or rows of vehicles.” The law allows two motorcycles side by side in a lane, but no lane splitting with other vehicles. Washington has debated legalization – bills have been introduced to allow filtering at slow speeds, but none have become law yet. The Washington State Patrol frequently reminds riders that lane splitting is illegal. Consequently, motorcyclists must not lane split in Washington, and doing so can result in a traffic citation under RCW 46.61.608 ​codes.findlaw.com​ codes.findlaw.com.

West Virginia

West Virginia does not allow lane splitting. West Virginia Code § 17C-15-44 covers motorcycle operation and entitles bikes to a full lane, while prohibiting passing in the same lane and riding between lanes of traffic. West Virginia is one of the states specifically identified as prohibiting lane filtering ​landline.media. No exception in law permits a motorcycle to split lanes. As a result, a rider in WV must change lanes to pass and may not weave through traffic jams. Lane splitting is illegal and enforceable under §17C-15-44. Violators can be stopped and cited by law enforcement for improper passing or lane usage.

Wisconsin

Wisconsin bans lane splitting. Wisconsin Statutes § 346.80(2) grants motorcycles full lane rights and explicitly states that no motorcycle shall be operated more than two abreast in a lane, nor shall any motorcycle operator overtake/pass in the same lane as another vehicle. Riding between lanes (lane splitting) is not allowed in Wisconsin. The Wisconsin DMV and State Patrol advise that motorcyclists must obey standard lane rules and that lane splitting is unlawful. Wisconsin has not entertained lane filtering legalization, so the practice remains prohibited. A motorcyclist lane splitting in Wisconsin would violate §346.80 and could be ticketed accordingly ​codes.findlaw.com​ codes.findlaw.com.

Wyoming

Wyoming does not permit lane splitting. Wyoming Statutes § 31-5-115 dictates that motorcycles are entitled to a full lane and shall not overtake another vehicle within the same lane. It also bars motorcycles from being operated between lanes or rows of vehicles. Therefore, lane splitting is illegal in Wyoming. Two-abreast riding for motorcycles is allowed, but that is the only lane sharing exception. Wyoming, being sparsely populated, hasn’t seen legislative efforts to change this. As of 2025, any form of lane splitting or filtering in Wyoming is against the law, and violators can be cited under §31-5-115 for improper passing or lane use ​codes.findlaw.com ​codes.findlaw.com.
