What is required of drivers when changing lanes?

When changing lanes, it is essential for drivers to yield to vehicles already occupying the lane they wish to enter. This means that before making the lane change, a driver should check their mirrors and blind spots to ensure that it is safe to move into the adjacent lane. Yielding effectively ensures that the driver does not cut off or interfere with the travel of other vehicles, promoting safer road conditions for everyone.

Failing to yield can lead to dangerous situations, including collisions, as vehicles may already be traveling in that lane or have the right of way. Therefore, understanding the importance of yielding during a lane change is crucial for road safety and maintaining proper traffic flow. This requirement helps drivers make informed decisions and contributes to an overall safer driving environment.
