What does BACK mean in cars?

[LaKeira]

The back of a car refers to the action of making a U-turn. More information about car U-turns is as follows: 1. A car U-turn is an operation that changes the direction of the car by 180° under road conditions where U-turns are allowed. Sometimes, U-turns are also needed in non-road conditions such as parking lots, and the methods are basically the same. 2. When making a U-turn, drivers must strictly comply with the regulations of road traffic management: "Motor vehicles are not allowed to make U-turns at railway crossings, pedestrian crossings, sharp turns, narrow roads, bridges, steep slopes, ramps, or sections prone to danger." 3. When a U-turn is necessary, choose intersections with low traffic volume, flat, wide, and safe areas with solid shoulders. Depending on the road width and traffic conditions, car U-turns can be performed either in a single forward movement or a combination of forward and reverse movements. 4. Cars should avoid making U-turns at railway crossings, pedestrian crossings, sharp turns, narrow roads, bridges, tunnels, culverts, steep slopes, ramps, or sections prone to danger, as this can easily lead to traffic accidents.
