Lane Filtering vs. Lane Splitting: Texas Motorcycle Laws

You pull up to a red light on I-35 near downtown Austin, traffic backed up ahead of you. A rider in front of you eases between the stopped cars and rolls to the front of the line. You have heard other riders call this “filtering.” You wonder whether it is legal, and what would happen to you legally if someone hit you while you were doing it.

Texas law on this exact question changed in 2023, and a lot of riders are still working off outdated information. Knowing where things stand right now could make a real difference to your claim if you are ever in a crash.

Lane Filtering vs. Lane Splitting: The Core Difference

These two terms describe different things, but Texas law treats them the same way.

Lane splitting means riding between two lanes of traffic that are moving in the same direction, at any speed. The motorcycle moves along the gap between two parallel lanes while cars around it are traveling at road speed.

Lane filtering means moving between stopped or nearly stopped vehicles, typically at intersections or in slow traffic, at low speed. The motorcycle is not keeping pace with flowing traffic; it is working through vehicles that are sitting still or barely crawling.

The distinction is important in everyday conversation, but less so in a Texas courtroom. Texas Transportation Code § 545.0605 prohibits both practices under the same statute, regardless of how fast traffic is moving.

Texas Law on Lane Filtering & Splitting

Before September 2023, Texas had no statute that explicitly addressed lane splitting or lane filtering. Riders who were cited for these maneuvers were typically cited under § 545.060, the general lane discipline rule requiring operators to stay within a single lane. That created some questions about whether filtering was technically prohibited at all.

That ambiguity ended on September 1, 2023, when § 545.0605 was added to the Transportation Code. The new section stated that a motorcycle operator may not ride between lanes of traffic moving in the same direction or pass a motor vehicle while in the same lane as the vehicle being passed. 

Both lane splitting and lane filtering became explicit violations under Texas law. A violation carries a fine of up to $200, plus a $50 state traffic fine and court costs that vary by court. If an officer considers the behavior dangerous, a reckless driving misdemeanor charge is also possible.

In 2025, riders pushed for a change. HB 2957, filed in the 89th Legislature, would have allowed filtering only when three conditions were all met: the road is a divided highway with at least two lanes in each direction; the vehicle being passed is stopped or moving at 10 mph or less; and the motorcycle is traveling at no more than 20 mph. The bill never made it out of committee and died when the session ended in June 2025. Filtering remains a violation under § 545.0605.

How Filtering Affects Your Injury Claim

Whether filtering was legal or not at the moment of your crash, it does not automatically end your right to compensation.

Texas uses proportionate responsibility under Texas Civil Practice and Remedies Code Chapter 33. Under that framework, each party involved in a crash is assigned a percentage of fault. Your compensation is reduced by your own fault percentage. If your share of fault is 51% or more, you cannot win anything. If it is 50% or below, you can still receive compensation, though the amount is reduced.

Since September 1, 2023, a rider who was filtering when a crash occurred faces a harder argument. The filtering itself was a statutory violation of § 545.0605. Insurance adjusters and defense attorneys could point to that violation as evidence the rider was acting outside the law, which made it easier to assign a larger share of fault onto the rider.

However, that did not mean automatic loss of the claim; a driver who changed lanes without signaling into the path of the filtering rider was still doing something wrong. But the rider’s violation gave the other side a clear target.

That violation is relevant to fault, but it does not end the claim on its own. A jury still weighs what the other driver did. The surrounding facts are still important: the speed of both vehicles, what the other driver did, whether signals were used, and what witnesses saw.

The Legislative History Behind These Laws

The current law did not arrive in a straight line.

Texas had no statute on lane splitting for most of its history. Riders operated under general traffic rules, and law enforcement handled filtering and splitting on a case-by-case basis under the lane discipline statute. In 2015, bills in both the Texas House and Senate proposed allowing lane splitting when traffic was moving at 20 mph or less. Neither passed, and a 2017 Senate bill died the same way.

SB 273, filed late in 2018 and considered by the 86th Legislature in 2019, tried again. That bill also died in committee.

In 2023, the legislature moved in the opposite direction. Rather than legalizing the practice, the 88th Legislature passed HB 4122, adding an explicit ban as § 545.0605. The law took effect September 1, 2023, and made both filtering and splitting clear violations for the first time.

In 2025, HB 2957 tried to swing the pendulum back by legalizing a narrow form of filtering. It died in committee. Texas went from no explicit rule to a flat ban, and the ban is still in place.

The practical consequence is that riders who heard about HB 2957 may believe filtering is now legal. It isn’t. For any crash on or after September 1, 2023, filtering and splitting are both violations of § 545.0605.
