Texas Motorcycle Accident Law: Helmet Statute (Transp. Code Ch. 661), Lane Splitting & Fault

Overview of Texas Law & Liability Framework

Texas motorcycle accident claims involve unique statutory rules governing adult helmet exemptions under Texas Transportation Code § 661.003(c), the explicit statutory ban on lane splitting enacted in Tex. Transp. Code § 545.060(e), and causal bio-mechanical apportionment when head injuries are alleged.

Key Texas Statutory Rules & Liability Standards

• Texas Helmet Law & Over-21 Exemption: Under Tex. Transp. Code § 661.003(c), riders age 21 and older are exempt from mandatory helmet wear if they have either successfully completed an approved motorcycle operator training course or are covered by a health insurance plan providing medical benefits for injuries sustained in a motorcycle crash.
• Comparative Fault & Helmet Non-Use: Even when an adult rider legally rides without a helmet under § 661.003(c), defense counsel in brain or cranial injury lawsuits may attempt to argue injury-causation apportionment under Nabors v. Romero; however, helmet non-use is irrelevant to non-head orthopedic injuries (such as femur fractures or road rash) because there is no causal nexus.
• Lane Splitting Expressly Illegal in Texas: Effective September 1, 2023 (HB 4122), Tex. Transp. Code § 545.060(e) expressly prohibits operating a motorcycle between lanes of traffic moving in the same direction ('lane splitting' or 'white-lining'), while explicitly permitting two motorcycles to ride two abreast in a single lane.
• Unprotected Left-Turn Liability: The single leading cause of urban Texas motorcycle fatalities is a passenger vehicle turning left across the rider's path in violation of Tex. Transp. Code § 545.152, which requires a left-turning driver to yield the right-of-way to a vehicle approaching from the opposite direction that is in the intersection or in such proximity as to be an immediate hazard.

Texas Court Procedure, Crash Reporting & Evidentiary Deadlines

Notice also that under Tex. Transp. Code § 661.003(c-1), a peace officer may not stop or detain a motorcyclist solely to determine whether the rider has completed a safety course or carries health insurance for the helmet exemption.

Compensatory & Exemplary Damages Available Under Texas Law

Emergency trauma care, skin grafts and orthopedic surgery (subject to § 41.0105), permanent scarring and disfigurement damages, physical impairment, lost wages (§ 18.091), custom motorcycle and riding-gear replacement, and UM/UIM or PIP benefits.
