Published on June 22, 2009, the Wisconsin Dooring law (Wisconsin ACT 22)imposes fines for drivers who open their car doors into bicyclists. More importantly, the law creates a duty for drivers to open their car doors in a safe manner without interfering with bikers on the road: "...
Biking at night in Wisconsin requires a white front headlight visibile 500 feet in front of the biker and a red reflector or red steady or flashing rear light visible from 500 feet behind the biker.
Bicyclists can ride two abreast/ side by side in Wisconsin as long as they do not impede the normal and reasonable movement of traffic.
Wisconsin bicycle laws are codified in the Wisconsin statutes. Drivers must give bikers at least three feet space before trying to pass from behind.
Look but fail to see types of collisions are fairly common when it comes to bicycle vs. motor vehicle collisions.
Biking with headphones may be unsafe, but there is no statute banning it.
Fixed gear bicycles are bikes that do not coast. State laws differ on what type of brake a bicycle must have. With a fixed gear bike, the rider can apply pressure against the pedals to cause the bike to skid. The bike chain and pedals provide the braking.
Bicycling upon a sidewalk can be dangerous. Although it takes the bicyclist off the roadway and there is less chance of being struck from behind, drivers of cars often fail to see bicyclists approaching from sidewalks.
Whether or not you can bike on a sidewalk in Wisconsin depends upon the local rule.
Wisconsin does not have a state law requiring helmet use for bicyclists or moped operators. Some cities have their own ordinances for children's bicycle helmet use.
