What must you do before you change lanes?

Before changing lanes, it is essential to check your mirrors, signal your intention, and check your blind spots. This procedure ensures that you are aware of your surroundings and can safely execute the lane change.

Checking mirrors allows you to see vehicles behind you and in adjacent lanes, while signaling communicates your intention to other drivers. Additionally, checking your blind spots is crucial because mirrors do not cover all areas around your vehicle. Blind spots are areas that are not visible through your mirrors, where a vehicle could be located, potentially leading to a collision if overlooked.

This comprehensive approach decreases the risk of accidents and contributes to a safer driving environment. Following this set of actions enhances your situational awareness and promotes responsible driving practices.
