Under what circumstances is a U-turn allowed at a red light?

[QuinnLynn]

When the center line of the road becomes dashed near the intersection or there is a U-turn passage in the central barrier, a U-turn is allowed at a red light. Below is relevant information about U-turns: 1. Regulations: Motor vehicles are not allowed to make U-turns at locations with no U-turn or no left-turn signs or markings, as well as at railway crossings, pedestrian crossings, bridges, sharp curves, steep slopes, tunnels, or sections prone to danger. Motor vehicles can make U-turns at locations without no U-turn or no left-turn signs or markings, but must not obstruct the normal passage of other vehicles and pedestrians. 2. Considerations: At any intersection, if there are dedicated U-turn signals or ground markings, always follow their instructions, which are usually located in the leftmost lane. Generally, as long as there are no no U-turn signs or separate U-turn signals, motor vehicles can make U-turns at any time without affecting normal traffic flow and ensuring safety. Typically, the central barrier on regular roads will change from a solid line to a dashed line near intersections, allowing vehicles to make U-turns in this area.
