At a yellow dashed line, U-turns are permitted; at a yellow solid line, U-turns are prohibited. Even if there is a sign allowing U-turns, you must wait for the green light to turn on before crossing the stop line to make a U-turn. Precautions for making a U-turn: When making a U-turn, you should turn on the left turn signal in advance, and the maximum driving speed should not exceed 30 kilometers per hour. Do not obstruct other vehicles and pedestrians traveling normally. Conditions allowing U-turns: There is a U-turn traffic light or sign; no U-turn sign but left turns are allowed (no prohibition of U-turn signs); U-turns can be made at dashed lines; U-turns can be made at yellow grid lines; U-turns can be made on the side with dashed lines in the green belt. Conditions prohibiting U-turns: U-turns are prohibited where there is a no U-turn sign or no left turn sign; U-turns are prohibited at crosswalks; U-turns are prohibited when there is no left turn lane; U-turns are prohibited within the second left turn lane line; U-turns are prohibited at yellow solid lines; U-turns are prohibited on highways.

When driving in the city, I often see issues with U-turns at yellow lines. Solid yellow lines absolutely prohibit U-turns as they indicate no crossing is allowed. Violating this rule can result in fines and penalty points if caught. Once, my friend made a U-turn at a solid yellow line and nearly collided with an oncoming vehicle – it was really dangerous! For dashed yellow lines, some areas permit U-turns under safe conditions, such as when there are no other vehicles at the intersection, but you must carefully check for 'No U-turn' signs. These rules vary by location – cities like Beijing, Shanghai, and Guangzhou enforce them strictly, while suburban areas may be more lenient. It's best to check local traffic regulations. My advice is to prioritize safety: it's better to take a detour than risk an unsafe U-turn to avoid accidents and potential liability.

Having driven for over a decade, I know that making a U-turn over a yellow line isn't as simple as it seems. A solid yellow line strictly prohibits any crossing maneuvers, including U-turns, and violating this can lead to rear-end collisions or being pulled over by police. A dashed yellow line allows U-turns, but you must ensure the intersection permits it, visibility is clear, and speed is slow to avoid disrupting traffic. It's best not to attempt this recklessly in urban centers where surveillance cameras are monitoring. New drivers often make this mistake – I did too when I was younger, but learned to rely more on GPS navigation for route planning. Remember, road safety is far more important than saving time. Let's all cultivate good driving habits.

When I first started learning to drive, I asked my instructor about the yellow lines. He said a solid yellow line is like a 'wall'—you must never cross it to make a U-turn, as it's both dangerous and illegal. A dashed yellow line allows cautious maneuvers, but you need to check traffic signals and flow—if unsure, don't attempt it. Rules vary slightly by region; Beijing enforces strictly, while rural roads may be more flexible. New drivers should study traffic rulebooks or apps rather than relying on hearsay. In case of an accident, handling it is troublesome, and insurance won't cover violations.
