State has a Far Right as Practicable Requirement

Cyclists moving slower than traffic must ride as close as practicable to the right-hand edge or curb, except when passing, turning, or avoiding unsafe conditions.

Allows Two Abreast Riding

Riders may travel two abreast if doing so does not impede the normal and reasonable movement of traffic, and must stay within a single lane on a two-lane-or-more roadway.

Single File is Required

Wisconsin does not require single-file riding; up to two abreast is permitted on the roadway, and more than two abreast only on ways set aside exclusively for bicycles.

Has a Safe Passing Law

A motorist overtaking a bicycle must leave a safe distance, never less than 3 feet, and must maintain that clearance until safely past the bicycle.

Helmets are required on the road

No statewide bicycle helmet requirement appears in ch. 346; local ordinances may impose one.

If Bike Lanes are present, they are required ( except when unsafe )

Bicycles may use the roadway, a shoulder, or a marked bike lane, but riders are not required to use a bike lane when one is present.

Riders may use the sidewalks

Riding on a sidewalk is prohibited by default under § 346.94(1), except at a driveway crossing, unless the local authority permits it. Where local authorities do permit sidewalk riding, § 346.804 requires the rider to yield to pedestrians and give an audible signal when passing.

Does the Impeding Statute Apply to Bikes

There is no general impeding-traffic statute that reaches bicycles (§ 346.59 applies only to motor vehicles). The only impeding-traffic restriction on cyclists arises when riding two abreast, which is not permitted if it impedes normal and reasonable traffic movement.

Whether cyclists may treat stop signs as yield signs (the "Idaho stop").

Bicyclists must obey the same stop-sign and right-of-way rules as other vehicle operators. Wisconsin has no law allowing cyclists to treat a stop sign as a yield.

Restrictions exist on e-bikes and usage

Electric bicycles receive the same rights and duties as regular bicycles and are exempt from motor vehicle licensing, registration, and financial-responsibility requirements, but no person under 16 may operate a Class 3 electric bicycle, and Class 3 speedometer/equipment rules apply.

Allows the concept of Contributory Negligence that allows any contributory fault resuls in 'no fault'

Wisconsin applies modified comparative negligence: a claimant's negligence reduces damages in proportion to their share of fault, and bars recovery entirely only once the claimant's negligence is greater than the negligence of the party from whom recovery is sought (the 51% bar).
