Under what circumstances can you make a U-turn without looking at traffic lights?

[LeMaya]

You can make a U-turn without looking at traffic lights under the following circumstances: On the side of a double yellow dashed line: If you are on the side of a double yellow dashed line in the middle of the road, you can make an immediate U-turn as long as you ensure there are no oncoming vehicles or it is safe to do so. On the side of an intersection dashed line: The lane center line is used to separate opposing traffic, and a dashed center line indicates that vehicles on the dashed side are allowed to cross the line to overtake the vehicle in front or turn left, meaning vehicles can make a U-turn directly from the dashed center line without passing through the crosswalk or entering the intersection. Within grid lines: Yellow grid line areas indicate no parking. If there is a red light ahead, vehicles behind should avoid this area. U-turns are permitted here as long as there are no guardrails in the middle and the vehicle avoids normal traffic flow before completing the U-turn in this area.
