What are the precautions for vehicle U-turns?

[MaggieLee]

Vehicle U-turns are highly prone to traffic accidents and require extra attention. Below are the precautions for vehicle U-turns: 1. Intersections with U-turn signals: At any intersection with dedicated U-turn signals or ground markings, always follow the instructions of the signals and markings. These are usually located in the leftmost lane, though in rare cases, they may be placed on the right. 2. Intersections without U-turn signals but with left-turn signals: Generally, unless there is a "No U-turn" sign or a dedicated U-turn signal, vehicles can make a U-turn at any time, provided it does not interfere with normal traffic and is safe. The central divider on regular roads often changes from a solid line to a dashed line near intersections, allowing U-turns in this area. 3. "No Left Turn" implies "No U-turn": If an intersection has a "No Left Turn" sign, even without a "No U-turn" sign, U-turns are prohibited. The "No Left Turn" sign carries the dual effect of prohibiting both left turns and U-turns. If the leftmost lane at an intersection is a straight lane, drivers cannot make a U-turn unless there is a "straight with arrow" marking, or they will be penalized. 4. Single solid yellow lines prohibit U-turns: Similar to intersections, U-turns are allowed on road sections without "No U-turn" signs. However, pay attention to the solid or dashed nature of the centerline: solid lines, whether single or double yellow lines, prohibit U-turns. Some roads have "yellow alternating lines" (one solid, one dashed). When making a U-turn, observe the line closest to you: if it's solid, U-turns are prohibited; if dashed, they are allowed. Note: Whether U-turns are allowed or not, U-turning vehicles must yield to oncoming traffic. If an accident occurs due to failure to yield, the U-turning vehicle is fully responsible. 5. Yellow grid areas: Yellow grid lines indicate no stopping. If the light is red, vehicles should avoid this area. However, U-turns are allowed here if there is no central divider. 6. Crosswalk areas: Some roads have crosswalks. Although there may be no "No U-turn" signs, these areas are equivalent to pedestrian zones, and U-turns are strictly prohibited. 7. No "No U-turn" sign implies permission: At intersections without "No Left Turn" or "No U-turn" signs, drivers can make U-turns without regard to traffic lights. However, if signs specify "U-turn when left-turn light is green" or "U-turn when red light is on," drivers must follow the traffic light instructions.
