Bicycle Law 2012
A new bicycle law which took effect April 2, 2012, requires motorists to leave a 4-foot "cushion of safety" when passing a bicyclist. To achieve this cushion, drivers may cross a roadway's center line when passing a bicycle on the left, but only when opposing traffic allows.
Drivers attempting to turn left must also yield the right of way to bicycle riders traveling in the opposite direction.
The new law also calls for bicycle riders to use all reasonable efforts to avoid impeding the normal flow of traffic. When there is only one travel lane, bicyclists may use any portion of the lane to avoid hazards on the roadway, including maintaining a safe distance from stopped and parked cars.
As always, bicyclists and motorists should obey all traffic signs and signals. PennDOT also recommends bicyclists always ride predictably and signal their intentions before proceeding so that motorists have a chance to react.
