The Truth About Bike Lanes: Bike lanes define space for bicycles on our crowded roads, but they are intended to keep cars out, not to keep bicycles in. Many bicyclists choose to ride in bike lanes but if they prefer to ride with other traffic, that’s legal too. Stopping or parking in a bike lane endangers bicyclists by forcing them out into traffic. The only time it is OK to cross a bike lane is when you are moving over to make a right turn.
