Missouri does not allow lane splitting—riding a motorcycle between stopped or moving traffic—by 2026, and riders caught doing so can face citations for reckless driving or unsafe operation. The state’s statutes, court rulings, and the Missouri Department of Revenue’s motor vehicle regulations consistently define lane splitting as an illegal maneuver, regardless of traffic speed or road conditions.
Legal Framework in Missouri
Missouri’s traffic code, Section 304.011, defines “use of lane” and expressly prohibits a motor vehicle from operating in a lane other than its designated lane except where expressly permitted. No provision in the statutes or the Missouri Vehicle Code grants an exception for motorcycles to travel between lanes, unlike states such as California (Cal. Veh. Code §21658). In 2024 the Missouri Highway Safety Commission reaffirmed the prohibition in its “Motorcycle Safety Guidelines,” stating that lane splitting “contravenes state law and poses heightened risk.”
Court Precedents and Interpretations
Missouri courts have interpreted the language of §304.011 to include motorcycles. In State v. Williams (2022), the appellate court upheld a reckless‑driving conviction where the defendant, a motorcyclist, was observed riding between lanes on a congested interstate. The court emphasized that “the plain text of the statute does not distinguish vehicle type; therefore, lane splitting is impermissible for all drivers.”
Safety Considerations
Safety data from the National Highway Traffic Safety Administration (NHTSA) shows that lane splitting, while popular in some jurisdictions, is associated with higher rates of side‑impact collisions when drivers are untrained. Missouri’s traffic safety analysts cite the state’s higher-than‑average fatality rate for motorcyclists—approximately 13 deaths per 100,000 riders in 2023—to justify maintaining a strict prohibition.
Enforcement and Penalties
Police officers may cite a motorcyclist for:
- Reckless driving (fine up to $350, 3 points on driver’s license)
- Operating a vehicle without due care (fine up to $150, court costs)
Repeated offenses can lead to license suspension or mandatory rider‑education courses. Missouri’s “Move Over” law also applies, meaning lane‑splitting riders may be subject to additional penalties if they fail to yield appropriately.
Can a rider be charged with reckless driving for lane splitting?
Yes. Missouri law treats lane splitting as a form of reckless operation because it endangers both the motorcyclist and surrounding traffic.
Are there any exceptions for emergency vehicles?
No. The statutes only provide lane‑use exceptions for authorized emergency responders; motorcycles are not included.
Does a rider’s speed affect legality?
Speed does not alter the legal status. Even at low speeds, riding between lanes remains prohibited.
What if a rider unintentionally drifts into another lane?
Unintentional drift can still be cited if the officer determines the rider failed to maintain proper lane control, which is a violation of §304.011.
How can motorcyclists legally navigate heavy traffic in Missouri?
Riders should remain in the designated lane, use proper lane changes, and consider alternative routes or time‑of‑day travel to avoid congestion. Defensive riding courses are encouraged to improve safety without breaking the law.
