What is the correct method for lane changing?

[MacHadley]

Before changing lanes, it is essential to turn on the turn signal in a timely manner to provide sufficient reaction time for the vehicles behind. Check the rearview mirror to observe the vehicles behind before changing lanes. Try to merge at a small angle to leave more safety space for the following vehicles.

When driving, I always change lanes carefully to ensure safety. Before preparing to change lanes, I first turn on the turn signal to alert vehicles behind me, then quickly glance at the rearview mirror to observe traffic conditions. After confirming there are no obstacles, I turn my head to check the blind spot for any approaching vehicles nearby. Then, I seize the right moment to decisively and smoothly merge into the new lane while maintaining a stable speed to avoid sudden acceleration or braking, which could cause a rear-end collision. Throughout the process, coordination between eyes, road, hands, and feet is crucial. It's also essential to anticipate other drivers' movements, especially on highways or in congested urban areas, to prevent accidents. After all, safety first is the fundamental principle of driving.
