U-turns are not allowed at intersections with double yellow lines. Double solid yellow lines indicate that overtaking and U-turns are prohibited for vehicles. Making a U-turn at a double yellow line will result in a 3-point penalty and a fine. Other situations where U-turns are prohibited include: U-turns are prohibited where there are 'No U-Turn' or 'No Left Turn' signs: If there is a sign indicating no U-turns, then U-turns are not allowed at that intersection. A U-turn is an extension of a left turn, so if there is a 'No Left Turn' sign at an intersection, U-turns are also prohibited there. U-turns are prohibited when there is no left-turn lane: Even in the leftmost lane, if there is no sign permitting left turns, U-turns are not allowed. U-turns are prohibited from the second left-turn lane: When a vehicle is in the second left-turn lane, it cannot make a U-turn. In the absence of any signs, vehicles can only make U-turns from the innermost left-turn lane. U-turns are prohibited on highways: Crossing the central divider to make a U-turn on a highway is illegal and will result in a fine and a 12-point penalty. If you miss an exit on the highway, continue to the next exit and leave the highway. Do not attempt an illegal U-turn.

As someone who has driven for most of my life, I've seen too many troubles caused by U-turns at intersections with double yellow lines. Those two bright yellow lines are clearly telling you not to cross them! Double yellow lines are solid lines specifically designed to separate opposing traffic flows. If you insist on making a U-turn, not only will you block other cars, but you're also likely to collide with oncoming vehicles. Last year, at a congested intersection, I saw a guy messing around and ended up being stopped by traffic police and fined 200 yuan, not to mention the cold sweat he broke out in. You need to understand these basic rules when driving—safety comes first. Next time you encounter this situation, just keep going straight and find a place with dashed lines or a U-turn sign to make your turn. It's worry-free and safe.

From a traffic regulation perspective, the double yellow lines at an intersection are a strict no-U-turn signal. Typically solid, these lines represent an absolute separation between opposing lanes, designed to protect you from collision risks. U-turns are only permitted at specific intersections, such as those with green arrow signals or dedicated U-turn signs. Otherwise, making an unauthorized U-turn violates traffic laws, resulting in a two-point deduction and a fine. This design is quite reasonable as it helps reduce congestion and accident rates during peak hours. Just last week, while studying urban road planning, I noticed many intersections have added dedicated U-turn lanes—but only where double yellow lines are absent. So when you encounter them, proceed straight without hesitation; don’t take chances.

During my novice days, I made a foolish mistake by attempting a U-turn at a crossroad with double yellow lines. The result was a chorus of honking horns and nearly causing an accident. My instructor later emphasized that double yellow lines are solid lines that must not be crossed, meaning no turning back and forth. U-turns should only be made at dashed lines or where signs permit. This is crucial for beginners—safety is always the bottom line. Every time I pass by, I remind myself to follow the rules.
