What should you do before changing lanes?

Before changing lanes, it is crucial to assess your surroundings to ensure the maneuver can be done safely. This includes checking the side view mirror to see the area beside you where you intend to merge, as well as checking the rearview mirror to understand the position of vehicles behind you.

Turning your head quickly to check for other vehicles is essential because mirrors can sometimes miss blind spots where vehicles may be present. Combining these actions helps ensure you have a complete understanding of the traffic conditions around you, which is vital for making informed decisions while driving.

Additionally, each of these actions contributes to a thorough and safe lane change process. By ensuring that all checks are made, you reduce the risk of collisions and enhance overall safety on the roads. Therefore, incorporating all of these checks is the best practice before changing lanes.
