Bicycle DUI Laws in Iowa

The rule
In Iowa, the DUI statute does not apply to bicyclists — it covers motor-vehicle operators only. Iowa's OWI statute (Iowa Code § 321J.2) applies only to operators of a 'motor vehicle,' and Iowa Code § 321.1(42) defines motor vehicle to exclude bicycles. Cyclists impaired in public may still face public-intoxication charges under § 123.46, but the OWI penalties - including a 180-day licence revocation - do not attach to bicycle operation. See Iowa Code § 321J.2 (Operating while intoxicated).

What this means in practice
A DUI charge isn't on the table for cyclists in Iowa, 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.
