Cycling safety in Wisconsin

Crash data

8 cyclist fatalities in 2023 · about 699 cyclist injuries.

In 2023, 8 bicyclists (pedalcyclists) were killed in Wisconsin motor-vehicle traffic crashes per NHTSA's Fatality Analysis Reporting System (FARS 2023 ARF, Table 6), 1.4% of the state's 583 total traffic deaths and a rate of 0.14 per 100,000 population — one of the lowest state rates in the country. WisDOT's own 2023 Bicycle Safety Fact Sheet (data from the UW TOPS Lab for the WisDOT Bureau of Transportation Safety) reports a slightly different count of 7 bicyclists killed, a common FARS-vs-state-crash-file discrepancy driven by differing crash definitions; the higher-authority FARS figure of 8 is used here. The same WisDOT fact sheet gives a clean statewide injury total of 699 bicyclists injured across 791 reported bicycle crashes in 2023 (roughly one bicyclist killed or injured every 12.4 hours). For a newer year, IIHS reports 8 bicyclist deaths in Wisconsin in 2024, but a clean statewide 2024 injury figure was not confirmed here, so 2023 is used for internal consistency.

Cycling rules in Wisconsin

Helmets: Wisconsin has NO statewide bicycle-helmet law for any age; WisDOT strongly recommends wearing one on every ride but it is not legally required. A few local jurisdictions may set their own rules, so check locally. (source)
Passing distance: A driver overtaking a bicycle going the same direction must leave a safe distance and in no case less than 3 feet of clearance, maintained until safely past (Wis. Stat. 346.075(1)). (source)
Sidewalk riding: There is no single statewide rule; sidewalk cycling is governed by local ordinance, so it may be permitted, restricted by age or area, or banned depending on the city or village. Where allowed, riders must yield to pedestrians. Check the local ordinance before riding a sidewalk. (source)
E-bikes: Wisconsin uses the 3-class e-bike system (motor 750W or less): Class 1 (pedal-assist to 20 mph) and Class 2 (throttle to 20 mph), and Class 3 (pedal-assist to 28 mph). No one under 16 may operate a Class 3 e-bike, though a younger rider may ride as a passenger (Wis. Stat. 346.806). Wisconsin does NOT require a helmet even on Class 3, since the state has no helmet law. (source)
Lights & reflectors at night: During hours of darkness a bicycle must have a white front lamp visible at least 500 feet ahead (the lamp may instead be worn by the rider), plus a rear red reflector visible from 50 to 500 feet; a steady or flashing red rear light visible 500 feet may be used in place of the reflector (Wis. Stat. 347.489). (source)
Direction of travel / where to ride: Bicyclists ride with traffic (same direction) and a rider going slower than traffic must keep as close as practicable to the right-hand edge or curb, except when passing, turning left, avoiding hazards, or when the lane is too narrow to share. Riding two abreast is allowed if it does not impede normal traffic flow (Wis. Stat. 346.80). (source)
Riding under the influence (OWI): Wisconsin's drunk/impaired-driving law (OWI, Wis. Stat. 346.63) applies to operating a MOTOR VEHICLE, and a human-powered bicycle is not a motor vehicle — so you generally cannot be charged with OWI for riding a standard bicycle drunk (unlike many other states). Impaired riding can still bring other charges, and a motor-powered bike operated under its own power can qualify as a motor vehicle. (source)
Stop-as-yield (Idaho stop): Wisconsin does NOT have a stop-as-yield / 'Idaho stop' law. Bicyclists are subject to the same rules of the road as other vehicles and must come to a full stop at stop signs and red lights. (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.
