When driving on a divided highway, what should a driver do when changing lanes?

When changing lanes on a divided highway, it is essential for a driver to signal their intention and ensure it is safe to move into the other lane. This practice is vital for several reasons.

First, signaling lets other drivers know your intentions well in advance, which is crucial for maintaining safety on the road. It provides a clear indication to surrounding vehicles that you plan to change lanes, allowing them to adjust their speed or position accordingly.

Second, ensuring that it is safe to change lanes protects everyone on the road. This involves checking mirrors and blind spots to confirm that there is adequate space and no oncoming vehicles or obstacles. Making a lane change without verifying safety can lead to dangerous situations, such as collisions.

Proper lane-changing practices contribute to smoother traffic flow and reduced risk of accidents. By adhering to these guidelines, drivers demonstrate responsibility and awareness, enhancing safety on the highway for themselves and others.
