What should you do every few seconds when slowing down or changing lanes?

The correct approach while slowing down or changing lanes is to check your mirrors frequently. This practice ensures that you are aware of your surroundings and can monitor the behavior of other vehicles around you. By doing so, you can better anticipate potential hazards, such as vehicles in your blind spots or approaching from behind, which is crucial for safely making these maneuvers.

Checking your mirrors allows you to maintain a complete picture of the traffic situation, aiding in decision-making. For instance, before merging or changing lanes, being aware of other vehicles’ positions helps prevent collisions and promotes safe driving.

While some other options may contribute to overall awareness, they do not capture the specific need for continuous visual checks that mirrors provide during these critical moments on the road.
