Is Lane Splitting Legal in Texas? What Section 545.0605 Says

Last reviewed: October 18, 2026. This article is general information, not legal advice. Texas traffic laws can change each legislative session; check the current Transportation Code before you ride.

Stuck on I-35 in Austin or the Katy Freeway in August, with the engine heat coming up through your boots, the gap between two lines of stopped cars looks very inviting. Texas law is unusually clear about that gap, and plenty of websites still get it wrong.

Short answer: Is lane splitting legal in Texas? No. Since September 1, 2023, Texas Transportation Code § 545.0605 expressly says a motorcyclist may not ride between lanes of traffic moving in the same direction, and may not pass a vehicle while in the same lane as it. That also rules out lane filtering at a red light. A 2025 bill to allow limited filtering (HB 2957) did not pass. For other states, see our state-by-state lane splitting guide.

The statute that bans it: § 545.0605

For years, Texas had no rule naming lane splitting. Officers relied on the general lane rule in § 545.060, which says a driver on a road with marked lanes "shall drive as nearly as practical entirely within a single lane" and "may not move from the lane unless that movement can be made safely." That left room for argument.

House Bill 4122 ended the argument. It was signed by the Governor on June 12, 2023 and added § 545.0605, "Operation of Motorcycles on Roadway Laned for Traffic," effective September 1, 2023. The section does four things:

1. Gives you the whole lane. A motorcycle "is entitled to full use of a lane," and a car may not be driven in a way that takes that away from you.
2. Allows two abreast. You may ride side by side in one lane with one other motorcycle.
3. Bans three or more abreast, riding between lanes of same-direction traffic, and passing a vehicle within its lane.
4. Exempts police officers performing official duties.

Texas has also been cited online under § 545.416. That section covers where riders and passengers sit on a motorcycle or moped (the permanent seat, passenger footrests and handholds, and a minimum passenger age of five). It says nothing about lane splitting. The rule you need is § 545.0605.

Splitting vs. filtering: both are banned in Texas

People use these words loosely, so it helps to separate them:

• Lane splitting means riding between lanes of moving traffic, for example along the line between two lanes on a freeway.
• Lane filtering means moving between stopped or crawling vehicles, usually to reach the front at a red light.

Some states, such as Utah and Arizona, ban splitting but allow filtering under tight conditions. Texas does not draw that line. Paragraph (B) covers riding "between lanes of traffic moving in the same direction," and paragraph (C) separately bans passing "a motor vehicle while in the same lane as the vehicle being passed." Paragraph (C) does not depend on traffic moving, so filtering past stopped cars is caught too.

Riding the shoulder to get past a jam is a different question, and it is not a workaround: § 545.058 allows driving on an improved shoulder only for a short list of purposes, and only when necessary and safe.

What about HB 2957? It did not become law

You may have read that Texas legalized lane filtering in 2025. It did not.

House Bill 2957, filed February 18, 2025 in the 89th Legislature, would have rewritten § 545.0605 to let a rider pass a vehicle in the same lane only if:

• the rider was on a divided highway with at least two lanes in each direction;
• the vehicle being passed was stopped or moving at not more than 10 mph;
• the motorcycle went no faster than 20 mph while passing; and
• the pass could be made safely.

The Texas Legislature's own record shows the bill was referred to the House Transportation Committee on March 20, 2025 and its status remained "In committee." It never received a committee vote, never passed either chamber and was never signed. The statute text published by the Legislature today still contains the full ban, with HB 4122 (2023) as its only enactment.

The Texas Legislature meets in regular session in odd-numbered years, so the next realistic chance for a filtering bill is the session that begins in January 2027. Until a bill passes both chambers, is signed and takes effect, the 2023 ban is the law.

Penalties for lane splitting in Texas

Section 545.0605 does not set its own fine. Texas therefore uses the general penalty in § 542.401: a person convicted of a misdemeanor under the traffic subtitle "for which another penalty is not provided shall be punished by a fine of not less than $1 or more than $200." Court costs are added on top, and the amount varies by court.

The bigger cost often comes later:

• Fault after a crash. If a car changes lanes into you while you are splitting, the other side will point out that you were riding in a way Texas law prohibits. That can reduce or defeat an injury claim.
• Insurance. Insurers look at how a crash happened when deciding who pays.
• More serious charges. Weaving through traffic at speed can be charged under other laws, such as reckless driving, depending on the facts.

Riding Texas traffic legally and safely

Since you cannot split or filter, the goal is to stay visible and keep an escape route:

• Use your full lane. Texas law gives you the whole lane, and drivers may not squeeze you out of it.
• Ride two abreast only with one other bike, and never three across.
• Pass in an open lane, the same way a car would.
• Stop with space ahead in a jam, a little off-centre, so you can move if a driver behind is not slowing.
• Watch your mirrors at the back of a queue, where rear-end crashes happen.
• Do not use the shoulder to bypass traffic except in the limited situations § 545.058 allows.

If you are a driver, the same section matters to you: do not crowd a motorcycle that is legally using a full lane.
