Bicycle DUI Laws in Missouri

The rule
In Missouri, the DUI statute does not apply to bicyclists — it covers motor-vehicle operators only. Missouri's DWI statute (RSMo § 577.010) applies to anyone operating a 'motor vehicle' while intoxicated. RSMo § 301.010 defines motor vehicle to exclude human-powered devices, so bicycles fall outside DWI. Public-intoxication and careless-and-imprudent-driving charges may still apply to an impaired rider. See RSMo § 577.010 (Driving while intoxicated).

What this means in practice
A DUI charge isn't on the table for cyclists in Missouri, but that's not a license to ride drunk — public-intoxication, reckless-conduct, and disorderly-conduct charges can still apply, and cycling impaired dramatically raises crash risk.
Ride sharp, ride legal
Run a 60-second pre-ride safety check
DUI, impairment, and distraction laws all assume you are riding a bike that is actually safe to ride. The M-check takes a minute and catches the things that get you hurt.
