Is Lane Splitting Legal in Texas?

Why Lane Splitting Is Illegal in Texas (Since September 1, 2023)

Lane splitting is not legal in Texas. HB 4122 (effective September 1, 2023) added Texas Transportation Code §545.0605, which prohibits motorcycle operators from operating between lanes of traffic moving in the same direction or passing a vehicle while in the same lane.

§545.0605 includes two narrow exceptions. Two motorcycles may ride side by side (abreast) in a single lane, and police officers performing official duties are exempt. No other exception exists, not for slow-moving traffic, not for stopped traffic at a red light, and not for highway shoulders.

Before HB 4122, no Texas statute explicitly addressed lane splitting, and no appellate court had ruled on it. Riders were cited under general lane-use provisions (§545.060 and §545.061) that did not clearly prohibit riding between lanes. HB 4122 resolved the ambiguity by creating §545.0605 as a stand-alone, motorcycle-specific prohibition.

The ban covers both lane splitting in moving traffic and lane filtering at stoplights, but the two practices are different in how they work and how other states treat them.

What Is Lane Splitting vs. Lane Filtering?

Lane filtering vs. lane splitting comes down to whether traffic is moving or stopped.

Lane splitting is operating a motorcycle between lanes of traffic moving in the same direction. The rider travels at speed alongside cars and trucks, sharing the space between active lanes on a highway or congested surface street.

Lane filtering is moving a motorcycle between stopped vehicles, typically at a red light or in gridlocked traffic. The rider advances to the front of the queue while all other vehicles are stationary. A handful of states (Utah, Montana, Arizona, Colorado, and Minnesota) allow low-speed lane filtering in stopped or slow traffic, with rider speed caps of 15 to 20 mph, while still prohibiting full-speed splitting.

Texas bans both practices under §545.0605. The statute draws no distinction between moving and stopped traffic. Any operation of a motorcycle between lanes is illegal.

Two related practices remain legal in Texas. Lane sharing (two motorcycles riding abreast in one lane) is the §545.0605 exception, and lane positioning within a single lane is a standard MSF safety technique, not lane splitting. Both are covered in the legal riding practices section below.

The following table breaks down four motorcycle riding practices and their legal status in Texas.

The diagram above clarifies a distinction that many riders get wrong. Filtering at a red light is just as illegal as splitting on the highway in Texas.

What are the penalties if you violate §545.0605?

Penalties for Lane Splitting in Texas

Lane splitting in Texas is a fine-only traffic violation under §545.0605. The consequences extend well beyond the traffic ticket itself.

A lane splitting violation triggers four categories of consequences that each affect the rider's finances and legal standing differently.

• Criminal penalty: Section 545.0605 sets no penalty of its own, so the general traffic penalty in Texas Transportation Code §542.401 applies. The fine runs from $1 to $200, plus standard court costs. The exact amount depends on the county, the judge, and the rider's record. No jail time applies.
• Insurance premium increase: A traffic citation for lane splitting goes on the rider's driving record. Motorcycle insurance carriers treat moving violations as a risk factor, and premiums can increase at the next renewal.
• Negligence per se in a civil claim: Because lane splitting is illegal, a violation counts as automatic negligence if the rider is later in a crash, and that can cost far more than the ticket.
• Comparative fault impact: Lane splitting feeds directly into Texas's modified comparative fault system under §33.001. If lane splitting contributed to the accident, your fault percentage increases. Cross the 50% bar, and you recover nothing.

The fine itself won't bankrupt you. The civil liability can. A $200 ticket is small compared to the loss of your entire personal injury claim because lane splitting pushed your fault past the 50% threshold. What can a motorcycle rider legally do in Texas?

Legal Motorcycle Riding Practices in Texas (What You CAN Do)

Texas bans lane splitting and lane filtering, but the state permits five motorcycle riding practices that riders confuse with splitting. Knowing the difference protects you on the road and in a courtroom.

• Lane positioning within a single lane: Riding in Position 1 (left third), Position 2 (center), or Position 3 (right third) of your own lane is legal, MSF-recommended, and NOT lane splitting. The MSF positioning section just below breaks down what each position is for.
• Lane sharing: Two motorcycles riding side by side (abreast) in a single lane are explicitly permitted under §545.0605 as an exception to the ban. Three or more motorcycles abreast in one lane are not permitted.
• Full lane rights: A motorcycle is entitled to the full use of a traffic lane under §545.0605(a)(1), and a motor vehicle may not be driven in a way that deprives a motorcycle of full lane use. A driver who crowds a motorcycle within its lane violates that rule.
• HOV lane use: Motorcycles may use HOV/carpool lanes regardless of the number of occupants under federal law (23 U.S.C. §166).
• Normal lane changes: A signaled lane change between lanes of traffic is legal. Moving from one lane to another is standard driving, not lane splitting.

Riders should also know their obligations under the Texas motorcycle helmet law, which creates its own set of rules and insurance defense issues for motorcycle accident claims.

MSF Lane Positioning (Positions 1, 2, and 3)

MSF lane positioning is the Motorcycle Safety Foundation's framework for where a rider should be within their lane at any given moment. The MSF divides a single traffic lane into three riding positions, each with different advantages for visibility and safety.

• Position 1 (left third): The default riding position. Best for visibility to oncoming and cross traffic, strongest lane dominance, and maximum distance from right-side hazards like parked cars and road debris.
• Position 2 (center): Least desirable for sustained riding. Oil, coolant, and transmission fluid from cars accumulate in the center of the lane (the "grease strip"). Riders pass through Position 2 when transitioning but rarely hold it.
• Position 3 (right third): Used when positioning away from left-side hazards or when passing vehicles in the right portion of the lane. Gives the rider more distance from oncoming traffic but less visibility to cross traffic.

The MSF teaches the S.E.E. strategy (Search, Evaluate, Execute) to guide positioning decisions. Search ahead for hazards. Evaluate the threat level and escape routes. Execute a position change or speed adjustment. This framework is the foundation of defensive riding.

The diagram above illustrates why a rider near the left edge of their lane is NOT lane splitting.

Texas bans lane splitting, but some states do allow it.

Where Is Lane Splitting Legal? State-by-State Overview

California is the only state that explicitly permits full-speed lane splitting in moving traffic. Most states either ban it outright or have no specific statute addressing it. A growing number of states have legalized a limited version, lane filtering at low speeds in stopped or slow traffic.

The following table compares lane splitting and lane filtering laws across states that have taken a definitive position on the practice.

Even in states where filtering is legal, full-speed lane splitting in moving traffic remains restricted or unregulated across most of the country. Texas is among the strictest. Both splitting and filtering are prohibited, with no speed threshold, no traffic condition exception, and no pilot program.

California's CVC §21658.1 stands alone. The law that codified lane splitting in California took effect in 2017 after years of informal acceptance. No other state allows full-speed splitting with no speed limit. Minnesota became the first to allow speed-capped splitting in moving traffic in July 2025, but it limits riders to 25 mph.

Will Texas change its position? That depends on the legislature.

Is Texas Likely to Legalize Lane Splitting or Lane Filtering?

Texas is not likely to legalize lane splitting in the near term. The legislature banned it explicitly in 2023, and no successful effort to reverse that ban has emerged.

HB 2957 was introduced in the 89th Texas Legislature (which ended May 2025). The bill would have allowed lane filtering at speeds under 10 mph when the rider was traveling under 20 mph. HB 2957 did not pass.

The ban under §545.0605 (HB 4122) remains in full effect. Riders and advocacy groups may push for a lane filtering bill in the 90th Texas Legislature, which begins January 2027. Bill filing opens November 2026. There is no guarantee a new bill will be introduced, and there is no guarantee it would pass if introduced.

Until the law changes, lane splitting and lane filtering remain illegal in Texas. Riders should rely on legal lane positioning (MSF Positions 1, 2, and 3) and full lane rights. For quick answers to the most common lane splitting questions, see the FAQ below.

Does Texas Have A Dead Red Law?

No. Texas has no "dead red" law that lets a motorcyclist proceed through a red light that fails to detect the bike. A rider facing a steady red must stop and wait like any other vehicle. Texas Transportation Code §544.0075 does require newer traffic-signal detectors to be capable of sensing motorcycles, but a sensor that misses a motorcycle does not give the rider legal permission to run the light. Riders sometimes confuse this with lane filtering, and both are illegal in Texas. Advancing between stopped cars at a red light remains banned under §545.0605 regardless of how long the signal has been red.
