Sit in stopped traffic on I-35 or 75 long enough on a motorcycle and you'll watch someone thread between the cars to get ahead. It happens constantly. That doesn't make it legal, and if you're the one doing it, or you get hit by someone who was, the actual state of the law matters a lot more than what riders around you seem to assume.
Here's the current, verified answer: lane splitting is illegal in Texas, full stop. There was a real push in 2025 to change that, and you may have seen articles claiming it succeeded. It didn't. Below is what the law actually says, what almost changed, and why it matters if you're ever in an accident.
The Short Answer: No, Lane Splitting Is Illegal in Texas
Texas Transportation Code § 545.0605 prohibits a motorcycle from operating between lanes of traffic moving in the same direction, and from passing a vehicle while sharing that vehicle's lane. It doesn't matter if traffic is crawling at 5 mph or stopped dead: the statute draws no distinction between "lane splitting" in moving traffic and "lane filtering" through stopped traffic. Both are the same violation under Texas law.
What the Law Actually Says
Section 545.0605 does three things. It gives a motorcyclist the right to full use of a lane, meaning other drivers can't legally crowd or squeeze a motorcycle out of its space. It allows two motorcycles to ride side by side within a single lane. And it prohibits operating a motorcycle between lanes of traffic moving the same direction, passing a vehicle while sharing its lane, or riding more than two abreast in one lane. The only exception written into the statute is for police officers performing their official duties.
About That 2025 Change You May Have Heard About
This is worth addressing directly, because it's a common source of confusion right now, and some legal blogs have gotten it wrong. A bill, House Bill 2957, was introduced in the Texas Legislature's 2025 regular session that would have created a narrow lane-filtering exception, allowing a motorcyclist to pass a vehicle in the same lane on a divided highway with at least two lanes each direction, if the vehicle being passed was stopped or moving at 10 mph or less, and the motorcycle itself was going no faster than 20 mph.
That bill was referred to the Transportation committee in March 2025. It did not pass. It was not signed into law. It never took effect. The current, codified text of § 545.0605 is unchanged from the version enacted in 2023, and the full prohibition on lane splitting and lane filtering remains in effect statewide today. If you've come across a source claiming Texas legalized limited lane filtering in September 2025, that source is incorrect, and it's worth double-checking anything you've read elsewhere on this topic against the actual statute.
A Motorcyclist's Right to the Full Lane
The flip side of this law is protective, not just restrictive. Drivers aren't allowed to operate their vehicle in a way that deprives a motorcycle of full use of its lane, no unnecessarily crowding a rider to the edge of the lane, no squeezing past within the same lane. If a driver's conduct pushed a motorcyclist into a dangerous position within their own lane, that can be relevant to fault in an accident, separate entirely from whether the motorcyclist was following the lane-splitting rules themselves.
Riding Two Abreast Is Fine, More Than That Isn't
One rule that sometimes gets lumped in with lane splitting but is actually completely legal: two motorcycles riding side by side within a single lane. Texas law specifically permits this. What it doesn't permit is three or more motorcycles riding abreast in the same lane, which falls under the same prohibition as lane splitting itself.
What Happens If You Lane Split and Get Into an Accident?
A lane-splitting violation doesn't automatically decide fault for a crash. Texas still looks at everyone's conduct and applies proportionate responsibility: if you're found 50 percent or less responsible, your recovery is reduced by your share; if you're found more than 50 percent responsible, you can't recover at all. A rider who was splitting lanes when a driver changed lanes without signaling into their path still has an argument, the driver did something wrong too. But the lane-splitting violation gives the insurance company or defense attorney a specific, statutory violation to point to, which tends to push more fault onto the rider than if the same accident had happened while the rider stayed in their lane.
Practically speaking, this means a lane-splitting rider involved in a crash faces a harder negotiation, not necessarily a lost case. The specifics of who did what, and when, still matter enormously.
