When changing lanes, you should not turn your head to check blind spots. Instead, use the left and right side mirrors to observe the situation behind you. If the side mirrors still don't provide a clear view of the rear, you should use the interior rearview mirror. Before changing lanes, always signal your intention by turning on the indicator lights in advance. This alerts both the drivers in front and behind you about your lane change. Never change lanes abruptly without signaling, as it is extremely dangerous and can easily lead to accidents. When changing lanes, first observe the rearview mirrors to confirm there are no vehicles or that the following vehicles are at a safe distance before proceeding.

As an ordinary driver, I always make it a habit to turn my head and check the blind spot every time I change lanes, as this practice has helped me avoid numerous accidents. The steps are simple: first, signal with the turn indicator to alert surrounding drivers, then quickly scan the lane situation through the rearview mirror. The crucial part is turning your head to look over your shoulder, usually rotating your right or left shoulder about 90 degrees, focusing your vision on the blind spot for about 1-2 seconds, and only proceeding with a smooth lane change after confirming there are no vehicles or obstacles. I think many people are lazy and rely solely on the rearview mirror, but that's unreliable—motorcycles or fast overtaking cars can easily hide in the blind spot. Having driven for over a decade, I find this action even more indispensable on highways, where a single oversight could lead to a rear-end collision. When practicing, I recommend starting on low-speed roads to develop a natural reflex. Be careful not to turn your head too abruptly, keep a firm grip on the steering wheel, and avoid veering out of the lane. Though this safety habit requires some effort, it protects both yourself and others, making it truly worth reminding yourself of every day.

As a driving instructor, I often teach students how to check blind spots when changing lanes: first, turn on the indicator to alert the following vehicle; then observe the rearview mirror to assess the road conditions; quickly and steadily turn your head about 90 degrees toward the blind spot, scanning the area to ensure safety; finally, gently steer to change lanes. During practice, I emphasize maintaining consistent speed without slowing down or looking down while turning the head. Common issues for beginners include turning the head too briefly or forgetting to check the rearview mirror, so I recommend repeated practice on quiet roads initially. I also remind them not to rely solely on high-tech aids like blind-spot monitoring systems—physically turning the head is the most direct safety measure. Mastering these small actions is the foundation of safe driving, significantly reducing accident risks.

Not checking the blind spot when changing lanes is dangerous. I must emphasize the importance of turning your head to check after signaling. Action: Turn your head about 90 degrees to the side to check the blind spot for one second, and proceed only when it's clear. Failing to do so may lead to accidents, especially on fast lanes where negligence can be fatal. Adhering to this small habit ensures safety.
