Bike lanes, or cycle lanes, are on-road lanes marked with paint dedicated to cycling and typically excluding all motorized traffic. A buffered bike lane is typically a lane with a wide painted buffer to demarcate a larger gap between the cycle lane and other traffic.[23] Contraflow bike lanes are typically a painted lane added to some one-way streets, to allow cycling traffic to safely travel in the opposite direction of all other traffic, including motorized vehicles and bicycles.
