What is the function of turn signals?

The function of turn signals is to indicate to pedestrians or other vehicles the direction in which the vehicle is about to turn, either left or right. On highways, they also indicate the direction for overtaking or lane changing. When both left and right turn signals flash simultaneously, it indicates that the vehicle is in an emergency situation, alerting other vehicles to pay attention. The light of turn signals is yellow, and they must be used when starting, changing lanes, or turning. Car turn signals can be classified by material into: 1. Gas car turn signals; 2. LED car turn signals. By base type, they can be divided into: 1. P21W; 2. PY21W; 3. W21W; 4. P27W; 5. W5W; 6. H5W. By location, they can be categorized into: 1. Front turn signals; 2. Rear turn signals; 3. Side turn signals.

Turn signals are mainly used to inform others that you're turning left, right, or changing lanes, allowing them to prepare in advance to avoid accidents. As someone who frequently commutes by car, I think this feature is absolutely crucial. On the road where everyone is moving, activating your turn signal is like shouting 'I'm about to turn,' helping prevent rear-end collisions from following vehicles or startling pedestrians at intersections. Don't use it too casually—activate the signal a few seconds before turning rather than flashing it at the last moment. Also, remember to turn it off after completing your maneuver; otherwise, the continuous blinking can be annoying. Don't underestimate its importance—it's legally required, and violations can result in fines. Once you develop the habit, driving becomes much smoother, reducing the risk of minor collisions and ensuring safety and peace of mind.

The function of turn signals is to emit signals indicating the vehicle's upcoming turning or lane-changing direction, enhancing traffic predictability. As someone studying automotive design, I find turn signals simple yet practical in design, utilizing LED technology for strong flashing and energy efficiency. They emit yellow flashes when the vehicle turns, alerting drivers and pedestrians ahead and behind to react promptly, preventing collisions. Research shows that correct usage can reduce accident rates by 25%. Don't activate them too late—operate them 50 to 100 meters in advance. Remember, bulbs can burn out easily, so check regularly to ensure they're working—don't slack off. These things are especially crucial on crowded city roads, directly impacting safety.

Turn signals are meant to let others know your next move and prevent accidents caused by sudden lane changes. Having driven trucks for ten years, I've seen too many collisions caused by forgotten signals. For example, failing to signal before changing lanes nearly caused a rear-end collision when the car behind rushed forward. Using them is simple: flash the signal a few times to communicate your intention before maneuvering. The downside is that broken signals must be repaired, as others won't understand your direction, which is dangerous. Making signaling a habit keeps traffic flowing smoothly.
