Is U-turn allowed at traffic light intersections?

[SanChristian]

Generally speaking, on the left-turn lane at a traffic light intersection, U-turns are allowed if there is no sign prohibiting U-turns. U-turn rules at traffic lights: At intersections with U-turn traffic lights or traffic signs indicating U-turn lanes on the roadway, U-turns are permitted when safety is confirmed. At intersections without U-turn lights but with left-turn lights, U-turns are allowed. Drivers can make U-turns using the left-turn lane at the central median or when approaching the intersection, provided it does not affect normal traffic flow. Yellow grid areas: Although parking is prohibited in yellow grid areas, if the traffic light ahead is red, vehicles behind should reasonably avoid stopping in this area. The U-turn operation can be completed at the central guardrail. Crosswalk areas: U-turns are not allowed on pedestrian crosswalks. Drivers can make a U-turn after crossing the crosswalk when the light is green, but must never make a U-turn directly on the crosswalk.
