When making a U-turn, the left turn signal should be turned on. The following situations prohibit U-turns: U-turns are prohibited where there are "No U-turn" or "No Left Turn" signs: If there is a sign prohibiting U-turns, then U-turns are not allowed at that intersection. The action of making a U-turn is an extension of a left turn, so if there is a sign prohibiting left turns at an intersection, U-turns are also prohibited there. U-turns are prohibited at crosswalks: U-turns are not allowed at crosswalks. If at an intersection where U-turns are permitted, you must cross the crosswalk before making a U-turn and should not make the turn on the crosswalk. U-turns are prohibited when there is no left turn lane: Even if you are in the leftmost lane, if there is no sign permitting left turns, U-turns are not allowed. U-turns are prohibited within 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 indicating otherwise, U-turns are only permitted from the innermost left turn lane. U-turns are prohibited at solid yellow lines: U-turns are not allowed at solid yellow lines. Even if there is a sign permitting U-turns, you must wait for the green light and cross the stop line before making the turn. 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 12 demerit points. If you miss an exit on the highway, continue to the next exit and do not attempt an illegal U-turn.

I've been driving for over ten years, and of course, you should turn on the left turn signal when making a U-turn—it's a basic rule. When I first learned to drive, my instructor repeatedly emphasized that a U-turn is essentially a large left turn, so you must signal left in advance to clearly communicate your intentions to vehicles behind you. Don’t wait until you're almost at the intersection to turn on the signal—doing it too late can easily lead to accidents, especially during peak hours with heavy traffic, as the car behind might not react in time. I remember once making a U-turn near a highway entrance without signaling, and a car almost rear-ended me. Since then, I've been extra careful. The rule is clear: failing to signal during a U-turn is illegal and can result in fines and penalty points. Just make it a daily habit—turning on the left signal is simple and safe, ensuring responsibility for both your own and others' driving while reducing accident rates.

As a recent driving school graduate, I was also confused about whether to turn on the left turn signal when making a U-turn as a beginner. After asking my instructor, I learned that a U-turn is essentially an extreme form of lane changing, equivalent to a large left turn, so the left signal must be activated. Now thinking about it, using the signal allows surrounding drivers to anticipate your action, avoiding the danger of sudden turns. For example, on city streets, making a U-turn without signaling may cause rear vehicles to misjudge the position, leading to side collisions. The core of safe driving is communication, and the left turn signal is a simple and efficient way to communicate. I even checked the traffic manual specifically, which states that using the left turn signal for U-turns applies to most scenarios. Only a few special sections like two-way single-lane roads may require hazard lights, but generally, the left signal takes priority. After developing this habit, driving feels smoother and more reassuring.

From my experience of getting a driver's license, turning on the left turn signal is mandatory when making a U-turn. This rule stems from the nature of a U-turn—it's essentially a left-turning maneuver that requires alerting following vehicles about the turning intention. From a safety perspective, activating the signal significantly enhances visibility, especially during nighttime or foggy conditions. Failing to signal may cause trailing vehicles to misjudge distance or speed, easily leading to accidents. The simple procedure is to activate the left turn signal a few seconds before reaching the U-turn point, ensuring smooth operation.

I remember learning in the traffic rules class that you usually need to turn on the left turn signal when making a U-turn, as a U-turn is defined as the operation of a vehicle changing direction to the left. This is similar to a left turn, where signaling is a requirement to facilitate overall traffic coordination. In practice, a common mistake is drivers thinking to turn on the right signal or not signaling at all, which can easily cause confusion. For example, if a driver flashes the right signal while making a U-turn, others might think they are turning onto a side road rather than turning back, increasing the risk of collision. The key is to activate the left signal in advance in legal zones, check if signs permit U-turns, and adhere to these practices daily to enhance efficiency and safety.

In daily driving, I've found that turning on the left turn signal for U-turns has become instinctive. A U-turn is essentially making a big left turn, so using the left signal is the most logical way to inform other drivers of your intention. Especially at busy intersections, activating the signal while checking mirrors can effectively prevent misunderstandings. My personal habit is to signal left about ten meters in advance, then turn slowly to avoid sudden braking. If there's a 'No U-turn' sign, I firmly avoid stopping there. This small signaling action provides significant protection, making driving safer and smoother.
