Notes

HRS § 291C-145 prohibits bicycle operation on a sidewalk within a business district. Outside business districts, sidewalk cycling is permitted but the rider must travel at no more than 10 mph, yield the right-of-way to pedestrians, and give an audible signal before overtaking. Counties may impose stricter rules - Honolulu prohibits sidewalk riding throughout downtown and Waikiki.

Statute

¹

A bell does not replace yielding or signaling, but it can warn other path users; compare bike bells and horns.

Applies to bicycles

Separate cycling DUI statute

No

BAC limit

Penalty

HRS § 291E-61 makes it unlawful to operate or assume actual physical control of a 'vehicle' while under the influence, and HRS § 291C-1 defines vehicle to include bicycles. A bicycle DUI carries the same statutory penalty range as an auto DUI - fines from $250 to $1,000 on a first offense, possible jail time, and a one-year driver-licence revocation if the rider holds a Hawaii licence.

If alcohol or drugs may impair the rider, do not ride; arrange another way home and secure the parked bike with a lock suited to the theft risk.
