Motorcycle Helmet & Lane-Splitting Laws in Texas

Texas riders crashed in significant numbers even before lane splitting was addressed by name in state law. thatcarhitme.com's own Texas crash tracking counted 11,937 crashes in 2025 alone, with another 902 in May 2026 alone¹². Some share of those involved motorcycles caught in the gap between an old, vague lane-position statute and the helmet law's age-21 cutoff. Two rules matter most if you ride in Texas: who has to wear a helmet, and where you're allowed to put your bike relative to other traffic. Both changed more recently than most riders realize.

Who actually has to wear a helmet

Texas Transportation Code Section 661.003 makes it an offense to operate or ride as a passenger on a motorcycle on a public street without protective headgear that meets the state's safety standard³. For anyone under 21, that's the end of the analysis: helmet, no exceptions, regardless of experience or how short the ride is.

Riders and passengers 21 and older get a way out, but it isn't automatic. The statute lets an adult ride bare-headed only if they can show one of two things, not both³:

• They completed a motorcycle operator training and safety course under Transportation Code Chapter 662, or
• They're covered by a health insurance plan that pays benefits for injuries from a motorcycle collision.

That second option trips people up. It means personal health insurance that would cover a hospital stay after a crash, not motorcycle liability or physical-damage coverage on the bike itself. Notice what's also missing: a dollar figure. The statute doesn't set a minimum policy limit, just that the coverage has to respond to collision injuries³. And the training course isn't a DPS program anymore. The legislature moved the Motorcycle Operator Training program from the Department of Public Safety to the Texas Department of Licensing and Regulation on September 1, 2020, so the course now has to come from a TDLR-licensed school taught by a TDLR-licensed instructor⁴⁵.

Enforcement has an odd wrinkle built in. Section 661.003 bars a peace officer from stopping or detaining a rider for the sole purpose of checking whether they've completed the course or carry the insurance³. In practice, that means an officer generally needs some other reason to pull an apparently-adult, helmetless rider over before the exemption question even comes up. Get stopped, and you're the one who has to produce proof; get stopped for something unrelated, and the helmet question may never surface. Either way, the fine for a bare violation is small: a misdemeanor punishable by $10 to $50³.

Lane splitting and lane filtering are flatly illegal now

For decades, Texas didn't have a law that named lane splitting. Riders and officers worked off the general single-lane rule in Section 545.060, which just says a driver on a multi-lane road has to stay in one lane as much as practical. That left room to argue either way, and citations under the old rule were inconsistent from one department to the next.

The legislature closed the gap with House Bill 4122, which added Section 545.0605 to the Transportation Code effective September 1, 2023⁶⁷. The new section cuts both ways. It gives a motorcyclist an affirmative right to full use of a lane, meaning another vehicle can't crowd a bike out of the space it's using⁶. Two motorcycles can also ride two abreast in a single lane if they choose to.

But the section draws three hard lines. A motorcyclist may not⁶:

• Ride more than two abreast in one lane,
• Operate between lanes of traffic moving in the same direction, or
• Pass another vehicle while sharing that vehicle's lane.

The middle item is lane splitting and lane filtering, covered without qualification. It doesn't matter whether traffic is crawling, stopped at a light, or moving at highway speed: threading between rows of vehicles is a violation either way, whether you'd call it splitting on the freeway or filtering up to a red light. The only carve-out is for a police officer performing official duties⁶. Section 545.0605 doesn't set its own fine, so the general Subtitle C penalty applies: a misdemeanor punishable by $1 to $200, the same default that covers most rules-of-the-road violations in Texas⁸.

How this plays out in an injury claim

Neither statute decides a personal injury case by itself, but both shape one. Texas runs on modified comparative negligence: a jury assigns each party a percentage of fault, and a claimant found more than 50% responsible for the crash recovers nothing⁹. If you were riding without a helmet and didn't qualify for either exemption, or you were splitting lanes when you were hit, expect the other driver's insurer to argue that conduct into the fault split, especially on how severe your injuries turned out to be rather than whether the crash happened at all. That doesn't bar recovery outright; it just moves the fight to percentages, and Texas has no rule that keeps a jury from hearing about it.

A citation written at the scene makes this harder to manage. If the responding officer marked you for lane splitting or a helmet violation while also citing the other driver for something like failure to yield, the adjuster now has a paper trail to point to before you've even filed a claim. That's a reason to get medical and legal documentation moving quickly rather than assuming the other driver's citation settles the matter.

There's also a clock running. Texas gives you two years from the crash date to file a personal injury or property damage lawsuit¹⁰. Miss it and the case is generally gone regardless of how clear liability was.

One more Texas-specific detail worth knowing if you ride: insurers here must include uninsured/underinsured motorist coverage on every auto liability policy unless the named insured rejects it in writing¹¹. Motorcyclists come out worse than car occupants in a crash with an uninsured driver, so check your own UM/UIM limits rather than assuming the other driver is covered.

After a crash

However the crash happened, Texas crash reports get filed with TxDOT's Crash Records Information System, and that report becomes one of the first things an insurer or attorney pulls to reconstruct lane position, point of impact, and who told police what at the scene¹². If you need to pull yours, thatcarhitme.com's Texas crash report guide walks through it.

Helmet status and lane position get litigated hard in motorcycle cases precisely because they're two things a defense team can point to that have nothing to do with who ran the light. If either issue is in play in your claim, it's worth talking to an attorney who handles motorcycle cases before you say anything to an adjuster about either one. You can find one through thatcarhitme.com's legal directory.
