Why can't you make a U-turn on white dashed lines?

Because making a U-turn on white dashed lines can easily lead to traffic accidents, and traffic regulations prohibit U-turns in such situations. Here is more information about road markings: 1. Yellow lines: Yellow lines are used to divide opposing lanes of traffic. A solid yellow line prohibits crossing the line, while a dashed yellow line allows turning or making a U-turn when there is no oncoming traffic. 2. White lines: A single solid white line prohibits lane changes. Any solid line prohibits lane changes; solid white lines separate lanes traveling in the same direction and are usually painted before traffic lights at intersections. A solid white line indicates that vehicles must stay in their lane and cannot cross into another lane traveling in the same direction. A dashed white line separates lanes traveling in the same direction, allowing vehicles to change lanes but not make a U-turn.
I see many drivers confused about why they can't make U-turns at white dashed lines. Actually, this involves fundamental principles of driving safety and road rules. White dashed lines are usually drawn between lanes, indicating that lane changes or overtaking are permitted, but they're not designated areas for making U-turns. Think about it: white dashed line zones often have heavy traffic and faster-moving vehicles. Suddenly making a U-turn there would leave vehicles behind you and in oncoming lanes unprepared, easily leading to rear-end collisions or head-on crashes. I've experienced this situation myself—once when I was in a hurry to make a U-turn, I almost got hit by an oncoming truck. It was a profound lesson. Now I always insist on making U-turns only at intersections or clearly marked U-turn zones—safety first. Driving isn't just about looking at road markings; you also need to pay attention to traffic lights and signs. Following the rules can reduce accident rates. Once you develop this habit, you'll find the roads smoother and everyone in a better mood.
After studying traffic regulations, I understand that white dashed lines cannot be used for U-turns primarily because they are not designed for this purpose. In driving courses, we repeatedly emphasize the specific meanings of road markings: white dashed lines indicate that vehicles can safely change lanes, such as on highways or urban streets, reminding you to be cautious with lateral movements. However, a U-turn requires a full 180-degree turn of the vehicle body. When performing this maneuver in a white dashed line area, your car may encroach on the opposite lane, obstruct traffic flow, and violate the original intent of traffic regulations. Many places explicitly prohibit U-turns at non-designated points, and violators may face fines or even penalty points. Having driven for over a decade, I always advise beginners to pay close attention to traffic signs. If in doubt, stop and observe before acting. Developing good habits will make the driving experience more enjoyable and safer.
