What are the key operating points for a vehicle U-turn?

[MacOwen]

Key operating points for a vehicle U-turn: 1. Turn on the left turn signal; 2. Observe traffic conditions, and after the signal has been on for three seconds, smoothly turn left into the inner lane; 3. If the left turn signal resets automatically, quickly turn it on again; 4. When moving forward in third gear to about 30 meters from the U-turn point, brake and shift to second gear, then brake again to shift to first gear; 5. After ensuring safety, quickly turn into the lane; 6. After completing the U-turn, quickly accelerate and shift gears. Before making a U-turn, the driver should pay attention to road traffic conditions, try to choose sections or intersections with less traffic, flat and wide enough to complete the U-turn in one maneuver, and it is recommended to do so at locations with U-turn signs.
