What is the standard width of a non-motorized vehicle lane?

[AniyahMarie]

When a non-motorized vehicle lane is set up on both sides of a motor vehicle lane, the width of each side should be no less than 3.5 meters; when a non-motorized vehicle lane is set up separately, the width should be no less than 5 meters. The state has standards for the width of each motor vehicle lane on highways. For multi-lane highways above the third grade, the width of each motor vehicle lane is 3 meters. Below is an introduction to traffic signals: 1. The function of traffic signals: Traffic signals are lights that direct traffic and generally consist of red, green, and yellow lights. A red light indicates prohibition of passage, a green light indicates permission to pass, and a yellow light indicates a warning. 2. Classification of traffic signals: Traffic signals are divided into motor vehicle signals, non-motorized vehicle signals, pedestrian crossing signals, direction indicator lights (arrow signals), lane signals, flashing warning signals, and road-railway level crossing signals.
