Cycling safety in Idaho

Crash data

7 cyclist fatalities in 2023 .

In 2023, 7 bicyclists (pedalcyclists) were killed in traffic crashes in Idaho, out of 275 total statewide traffic fatalities that year (NHTSA FARS 2023). A clean, verified statewide bicyclist-injury count could not be extracted from an official Idaho Transportation Department source, so that figure is left null; ITD's annual Idaho Traffic Crashes report includes a bicyclist section for readers who need injury detail.

Cycling rules in Idaho

'Idaho stop' (the original stop-as-yield law): Idaho was the first state to adopt this (1982): a cyclist may treat a stop sign as a yield - slowing and stopping only if needed for safety before proceeding - and must stop at a steady red light but may then cautiously proceed after yielding to all other traffic. Applies to bicycles, human-powered vehicles, and electric-assisted bicycles. (source)
Helmets: Idaho has no statewide bicycle helmet law for riders of any age; some cities (for example, Boise) require helmets for riders under 18, so check local ordinances. (source)
Passing distance: Idaho has no specific numeric (e.g. 3-foot) safe-passing law for bicycles; motorists must pass on the left and return only when safely clear under the general overtaking rules, leaving a safe distance to judgment. (source)
Sidewalk riding: Riding on sidewalks is generally allowed under state law, but a cyclist must yield the right-of-way to pedestrians and give an audible signal before passing, and may not ride where prohibited by official traffic-control devices; local jurisdictions may add restrictions (e.g. downtown areas). (source)
E-bikes (3-class system): Idaho defines an electric-assisted bicycle as having fully operable pedals and a motor under 750 watts, in three classes: Class 1 (pedal-assist up to 20 mph), Class 2 (throttle up to 20 mph), and Class 3 (pedal-assist up to 28 mph). (source)
Lights and reflectors at night: When ridden at night, a bicycle must have a front light-emitting device visible from at least 500 feet and a reflector clearly visible from the rear. (source)
Direction of travel / where to ride: A cyclist riding slower than traffic must ride as close as practicable to the right-hand curb or edge of the roadway, with exceptions for passing, preparing to turn left, avoiding hazards, or narrow lanes (and may keep left on one-way multi-lane roads). (source)

Cities and counties often add their own rules (for example, where you can ride on sidewalks or boardwalks). Check the local ordinance for the specific town you're visiting.
