Hiking, Biking & Beaches
Biking on the road
In Missouri, a bicycle is a vehicle. Riders get basic road rights and driver-like duties, plus a few bike rules.
Start here
A bicycle — and an e-bike — is a vehicle, with the same rights and duties as any driver under Chapter 304, plus a few bicycle-specific rules (RSMo 307.188).
Ride with traffic, as far right as is safe
Ride with traffic, as far right as is safe (RSMo 307.190) — except when you're turning left, passing, avoiding a hazard, or in a lane too narrow to share. Obey all traffic laws, and signal your turns and stops.
Lights at night
At night — from a half-hour after sunset to a half-hour before sunrise — you need a white front light visible at 500 feet and a red rear reflector or lamp visible from behind, plus side and pedal reflectors (RSMo 307.185). A rear light is the smart choice.
Brakes
Brakes that can stop you within 25 feet from 10 mph.
Sidewalks
No riding a bicycle on a sidewalk in a business district (RSMo 300.347). Elsewhere, local rules decide — and you must yield to people on foot and give an audible signal before you pass. No motorized bicycle on a sidewalk, anywhere.
The passing law
It's a "safe distance" — not a fixed three feet
A driver passing you must leave a safe distance and keep that clearance until safely past (RSMo 304.678). Missouri's law does NOT set a fixed three-foot number — three feet is a good rule of thumb, not the legal figure. A violation is an infraction, or a class C misdemeanor if there's a crash.
Helmets
Missouri has no statewide helmet law for bicycles — for adults or kids — though some cities have their own. Wear one anyway: most serious bike injuries are head injuries.
