Can You Make a U-Turn at a Circular Signal Light?
4 Answers
At sections without prohibited U-turn signs, you can make a U-turn when the light is green, but you must not hinder the normal passage of other vehicles and pedestrians. Methods for making a U-turn at a circular signal intersection: One-step forward U-turn (using the left or right side of the intersection): To make a U-turn using the right side of the intersection, turn on the right turn signal, slow down, and shift to an appropriate gear. Observe the traffic on the right, turn right, proceed forward appropriately, then turn on the left turn signal before turning left. Observe the traffic ahead and behind, turn left, and complete the one-step forward U-turn after confirming safety. To make a U-turn using the left side of the intersection, turn on the left turn signal, slow down, and shift to a lower gear. Observe the traffic on the left and ahead, as well as behind. Turn appropriately based on the intersection position to complete the one-step forward U-turn. To make a U-turn using the right side of the intersection with reverse gear, turn on the right turn signal, proceed forward through the intersection, and stop. Shift into reverse gear, turn on the left turn signal, and use the interior and exterior rearview mirrors as well as turning your head to observe the traffic ahead and behind. Start moving, turn right, and back the vehicle into the right side of the intersection before stopping. Turn on the left turn signal, observe the traffic on both sides, and safely exit the intersection to complete the U-turn.
Having driven a taxi for over a decade, I've learned that when encountering a circular traffic signal and wanting to make a U-turn, it's generally permissible to do so when the light turns green, provided there's no 'No U-turn' sign at the intersection or double solid yellow lines on the road. However, one must be cautious as some intersections may appear ordinary but have hidden rules. For instance, near my residential area entrance, there's an unmarked intersection where I once got fined for making a U-turn on green. Now I've wised up—before stopping, I always glance at the side and rearview mirrors to ensure no cars are coming. Other factors to consider include road width and traffic volume; it's best not to risk it on narrow roads or during peak hours.
I usually pay attention to driving safety and believe that when the circular signal light is green and there's no prohibition sign, making a U-turn is acceptable, but the key is to ensure a safe distance—keeping at least several dozen meters from oncoming vehicles. Never rush just because the light is green; observe the intersection design: for example, if there's a median or a turn arrow, you'll need to detour. On a related note, rules vary slightly between cities. For instance, in central Shanghai, many intersections completely prohibit U-turns, so check your navigation map in advance to avoid trouble.
I just got my driver's license, and my instructor taught me that U-turns are allowed under a circular green signal as long as there's no red cross sign. However, I was once stopped by a police car when making a U-turn at a new intersection under a green light—they said it was prohibited by default even without signage. Now I've learned my lesson: I drive slower and always check road signs before acting. A related point is that beginners often overlook the solid or dashed yellow lines on the road—dashed lines allow U-turns, while solid lines do not.
