Whether you can make a U-turn when the left turn signal is red depends on the road conditions: 1. If there is a no U-turn or no left turn sign at the intersection, you cannot make a U-turn when the left turn signal is red; 2. If there is no no U-turn sign at the intersection, you can make a U-turn when the left turn signal is red; 3. If there is a dashed line gap in the middle of the road before reaching the stop line, and there is no no U-turn sign at the gap, you can make a U-turn; 4. If there is a no U-turn sign at the gap or the line is solid all the way, you cannot make a U-turn at the gap and must proceed to the stop line to make a U-turn. Traffic lights, also known as traffic signals, are signs that indicate whether vehicles and pedestrians can proceed.

After driving for so many years, I've learned that making a U-turn at a left-turn red light is a strict no-no—you must wait for a green light or a dedicated U-turn arrow. Many beginners might think it's okay to try if there are no cars around, but in reality, making a U-turn on red is equivalent to running a red light. Not only is it illegal, resulting in fines and points deducted, but it also significantly increases the risk of colliding with oncoming vehicles or pedestrians. Once, a friend of mine impulsively tried it, got caught by a traffic camera, and nearly sideswiped another car. Traffic regulations may vary slightly by location—for instance, a few intersections have signs indicating 'U-turn permitted on red'—but in 99% of cases, we must wait for the signal to change. Safety comes first, so I always make it a habit to check for signs well before reaching an intersection. This habit has saved me a lot of trouble.

When I first learned to drive, I often asked this question too. The driving instructor repeatedly emphasized: when making a left turn and encountering a red light, don't even think about making a U-turn—you must obediently stop. It's not a multiple-choice question; it's a rule designed for everyone's safety. If you force a U-turn, not only will the cameras capture it, but you might also cause an accident, especially at busy intersections in big cities. I've also looked it up, and most cities explicitly prohibit it, except in rare cases like when a green left-turn arrow is lit. In short, once I started driving, I learned to patiently wait for the green light—it saves trouble and avoids risks, which is much better than trying to cut corners.

Every time I drive, I think that making a U-turn at a red left-turn light is too dangerous, which is equivalent to ignoring the signal. Legally, it's considered a violation, not to mention the fine, but worse, it could cause a collision. I've seen similar accidents where a U-turn was made without properly checking the straight direction, leading to a chain-reaction rear-end collision. Rules are there to ensure everyone's safety, so whenever the red light is on, just stay put and wait. Don't take the risk; waiting for the green signal is much safer.

As a car enthusiast, I carefully observe surrounding signs when facing a left-turn red light—most places prohibit U-turns, but occasional exceptions exist where "Permitted" signs require cautious maneuvering. In practice, safety comes first, with no room for gambling. The joy of driving stems from freedom within rules, like observing road conditions and learning sign recognition skills while waiting for green lights. Sticking to this principle has kept me accident-free.

Having driven for many years, I fully understand that making a U-turn at a left-turn red light is strictly prohibited unless specially permitted. Young drivers often make this mistake, thinking it saves time, but forget that the essence of the rules is to protect lives. A single mistake can harm both others and oneself, not to mention the severe penalties and the impact on insurance rates. From my experience, strictly adhering to traffic signals is the most reliable approach. When encountering a red light, wait patiently and never act impulsively. This responsibility must always be kept in mind.
