Before changing lanes in front of another vehicle, what should you see in your rearview mirror?

When changing lanes, it’s crucial to be aware of the traffic around you to ensure safety for yourself and others on the road. The correct answer highlights the importance of visibility in your rearview mirror. Specifically, seeing the pavement or at least the headlights of the vehicle behind you indicates that you have a clear line of sight and can safely merge into the next lane without risking a collision.

Headlights in your rearview mirror serve as a reminder of the vehicle's position so you can gauge its distance from you. If you only see the pavement, it suggests that the road is clear of vehicles directly behind you, which is an essential consideration when you are planning a lane change.

Other options might focus on the presence of vehicles or certain distance parameters, but the key factor is ensuring that you have a clear understanding of the space behind your vehicle before executing the maneuver. This helps to maintain safe driving practices and reduces the likelihood of accidents caused by unexpected obstacles or vehicles in close proximity.
