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

Checking your mirrors before changing lanes is crucial for safety and collision avoidance. By doing so, you become aware of the vehicles surrounding you, including those that may be in your blind spots or approaching quickly from behind. This awareness allows you to make informed decisions about whether it is safe to change lanes. Maintaining a clear view of nearby vehicles helps to prevent accidents and ensures that you can navigate roadways safely.

While increasing visibility and adjusting orientation are important aspects of vehicle operation, they do not directly address the primary reason for mirror checks, which is to enhance situational awareness and avoid potential collisions. Additionally, minimizing fuel consumption is not related to the importance of checking mirrors before making a lane change.
