What should you check before changing lanes?

Before changing lanes, it is crucial to check the mirror, signal, and blind spot because this ensures safe lane changes by providing a comprehensive assessment of the surrounding traffic situation.

Checking the mirrors allows you to be aware of the vehicles and conditions behind and alongside you. Signaling your intention to change lanes communicates to other drivers that you are about to make a movement, which helps prevent collisions. Finally, checking your blind spot is essential because mirrors may not capture all vehicles in adjacent lanes, particularly those that are closer to your vehicle. Failing to do a thorough check can lead to dangerous situations, including accidents with vehicles that may be in your blind spot.

This thorough approach promotes safety for both the driver and other road users, making it a critical habit for effective driving.
