The 3-foot rule says that motorists may not be within 3 feet of a moving bicycle even when passing (Sec. 706.5). When passing a cyclist, a driver may cross the center line, if necessary, to provide adequate space and distance to the cyclist, provided the pass can be made safely. A pass may not be made within 100 feet of an intersection or when approaching a curve in the road that obstructs the motorist's view (Sec. 701).
