Motorcycle Accident Claims in Missouri

The Missouri helmet law, whether lane splitting is legal, how fault is shared after a motorcycle crash, and the deadline to sue.

Short answer: Motorcycle and motortricycle operators and passengers under 26 must wear a helmet whenever the vehicle is moving, and so must operators 26 or older riding on an instruction permit; other adult riders are not required to wear one. Mo. Rev. Stat. §302.020.2

Motorcycle helmet lawMotorcycle and motortricycle operators and passengers under 26 must wear a helmet whenever the vehicle is moving, and so must operators 26 or older riding on an instruction permit; other adult riders are not required to wear one. Local governments may not impose their own helmet rules, and no one may be stopped just to check helmet compliance. The section does not say that not wearing a helmet reduces damages in a lawsuit.
Lane splittingNo Missouri statute read names lane splitting. On roads divided into lanes, the state traffic law requires a vehicle to be driven as nearly as practicable entirely within a single lane and not moved from that lane until the driver has made sure the move can be made safely.
Missouri's statutes read do not separately address riding between lanes; how §304.015 applies to motorcycles is not stated in the statute.
Fault rule (comparative negligence)Pure comparative fault. In product liability claims, the statute expressly applies pure comparative fault: the plaintiff's fault reduces the award proportionately but does not bar recovery. Missouri applies the same pure comparative fault approach to negligence cases generally through court decisions. In dog-bite cases, damages are reduced by the injured person's percentage of fault.
Minimum car insuranceOwners must maintain financial responsibility; a motor vehicle liability policy must cover at least $25,000 per person and $50,000 per accident for bodily injury and $25,000 for property damage.
