Is it allowed to make a U-turn at a green light?

[Leo]

At intersections with traffic signals and no markings, motor vehicles are allowed to make a U-turn when the light is green. However, if there are clear markings prohibiting U-turns at a traffic signal intersection, motor vehicles are not allowed to make a U-turn even when the light is green. Rules for U-turns at traffic lights: At intersections with U-turn signals or traffic signs indicating U-turns on the lane, U-turns are permitted under safe conditions. At intersections without a U-turn signal but with a left-turn signal, drivers can make a U-turn using the central median or the left-turn lane near the intersection, provided it does not interfere with normal traffic flow. Yellow grid zones: Although parking is prohibited in yellow grid zones, if the traffic light ahead is red, drivers should avoid stopping in this area. The U-turn operation can be completed at the central guardrail.
