Cycling safety in Iowa

Crash data

5 cyclist fatalities in 2023 .

In 2023, 5 bicyclists (pedalcyclists) were killed on Iowa roadways, out of 377 total traffic fatalities statewide, according to NHTSA's FARS-based figures. A clean, official statewide bicyclist-injury count for the same year was not verified from an Iowa DOT source, so cyclistInjuries is left null rather than estimated. Iowa DOT publishes detailed, filterable crash data (including bicycle-involved crashes) through its Traffic Safety Resource Guide and open-data crash tools for those who need injury-level detail.

Cycling rules in Iowa

Helmets: Iowa has no statewide bicycle helmet law for riders of any age; helmet use is voluntary, though some local jurisdictions may set their own rules. (source)
Passing distance: Iowa does NOT set a specific numeric (e.g., 3-foot) passing distance; drivers overtaking a bicycle must simply pass at a safe distance and not return to the right until safely clear (Iowa Code 321.299). (source)
Sidewalk riding: There is no statewide statute banning or authorizing bicycle riding on sidewalks in Iowa; sidewalk riding is generally governed by local city ordinance, so rules vary by community. (source)
E-bikes: Iowa recognizes the three-class low-speed electric bicycle system (Class 1 pedal-assist to 20 mph, Class 2 throttle to 20 mph, Class 3 pedal-assist to 28 mph); e-bikes under 750W are treated as bicycles, must carry a class/speed/wattage label, and Class 3 riders must be at least 16 (Iowa Code 321.235B). (source)
Lights and reflectors at night: When lights are required (roughly sunset to sunrise), a bicycle must have a front white light visible at least 300 feet and a rear red light or red reflector visible at least 300 feet (Iowa Code 321.397). (source)
Direction of travel / where to ride: Bicyclists must ride on the right side of the roadway and, when moving slower than traffic, keep as near as practicable to the right-hand curb or edge, except when passing, turning left, or avoiding hazards (Iowa Code 321.297). (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.
