The rule
In Delaware, the DUI statute does not apply to bicyclists — it covers motor-vehicle operators only. Delaware's DUI statute (21 Del. Code § 4177) applies only to operators of a 'motor vehicle, off-highway vehicle or moped,' and 21 Del. Code § 101 defines motor vehicle to exclude bicycles. Impaired cyclists may still face reckless-driving or public-intoxication charges, but the DUI penalties — including a 12- to 24-month licence revocation and ignition interlock — do not attach to bicycle operation. See 21 Del. Code § 4177 (Driving a vehicle while under the influence).
A DUI charge isn't on the table for cyclists in Delaware, 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.
