Why is it important to check your mirrors before changing lanes?

Checking your mirrors before changing lanes is crucial for ensuring the lane is clear of obstacles. This action allows you to observe any vehicles, cyclists, pedestrians, or objects that may be present in the lane you intend to occupy. By doing this, you can gauge whether it is safe to make the lane change without posing a danger to yourself or others on the road.

While gathering information about traffic conditions is also an important aspect of mirror use, the primary emphasis when changing lanes is to confirm that the lane itself is free from hazards. Adjusting your vehicle's position and maintaining a safe following distance are important driving practices but are not the primary reasons for checking mirrors when preparing to change lanes. This focus on ensuring lane safety helps prevent accidents and promotes responsible driving behavior.
