Car needs to use turn signals in the following situations: 1. When making a left or right turn; 2. At a distance of 30 to 100 meters from an intersection, turn on the turn signal according to the turning direction; 3. When changing lanes without hindering the normal driving of vehicles in other lanes, the corresponding turn signal should be turned on in advance before changing lanes; 4. Turn signals should be used when overtaking; 5. Correct use of turn signals is required when making a U-turn, entering or exiting a roundabout, and starting to park; 6. Turn signals should be correctly used when entering the highway from the ramp. Turn signals are important indicator lights that are turned on when a motor vehicle turns to alert vehicles and pedestrians around it.

Using turn signals while driving is absolutely crucial! I always make sure to signal before turning, changing lanes, or starting off. When turning, I activate the indicator at least 30 meters before the intersection. For lane changes or overtaking, I insist on signaling for over 3 seconds before steering to give trailing vehicles ample reaction time. On highways, signaling is mandatory when entering or exiting ramps, and promptly engaging the right turn signal is essential when exiting roundabouts. Even for temporary roadside parking, activating the right turn signal alerts following vehicles to steer clear. During rain or nighttime driving with poor visibility, early signaling can be lifesaving. Developing this habit isn't just about avoiding fines—it's fundamentally about communicating your intentions clearly to other drivers.

The essence of using turn signals is to communicate driving intentions to other vehicles in advance. From my first day of driving, I developed the habit: activating the left turn signal 50 meters before turning left, and similarly for right turns. When changing lanes, I always turn on the signal 3-5 seconds before steering. Starting from the roadside requires the left turn signal to avoid rear-end collisions. Roundabouts demand particular attention—no signal is needed when entering, but a right turn signal is mandatory when exiting. On highway ramps, it's crucial to signal 200 meters ahead. Many forget to use turn signals when reversing out of parking spots, but the corresponding direction's signal should be activated. In rainy or foggy conditions with visibility under 100 meters, turn signals become lifesavers. These details may seem trivial, but they prevent 80% of minor collisions.

There are several key moments when using turn signals is crucial. You must activate the left turn signal when starting to move, alerting vehicles behind you. Always signal before changing lanes - I prefer flashing the signal for 3-4 seconds before maneuvering. Activate your turn signal before entering the solid line zone when making turns at intersections. Use the left signal before U-turns and the right signal when pulling over to park. When preparing to exit a roundabout, engage the right turn signal. On highways, signal well in advance when entering or exiting. Turn signals become even more critical during rainy conditions or nighttime driving. Missing any of these operations can easily lead to accidents, especially during heavy traffic periods like rush hours. Remember, the core function of turn signals is to let other drivers anticipate your vehicle's movement by signaling in advance.
