What factor is crucial to consider when making a lane change?

When making a lane change, visibility and blind spots are crucial factors to consider. It's essential to ensure that you can see other vehicles in adjacent lanes as well as in your blind spots—those areas that are not visible in your mirrors. Checking blind spots typically involves looking over your shoulder to confirm that it's safe to move into the next lane.

This careful assessment not only helps you identify vehicles or obstacles that may be present but also prevents potential collisions, ensuring a safer driving experience for both you and others on the road. Proper visibility allows you to make informed decisions about when to change lanes, aligning with safe driving practices.

This component of lane changing is foundational to the concept of vehicle maneuverability and awareness in traffic, prioritizing safety over other less critical factors.
