How often should a driver check their mirrors while driving?

The correct answer emphasizes the importance of regularly checking mirrors every 5 to 10 seconds while driving. This practice ensures that drivers maintain a constant awareness of their surroundings, which is crucial for safe driving. Regular mirror checks help to monitor the positions of other vehicles, anticipate potential hazards, and make informed decisions about lane changes or maneuvers. By doing this frequently, drivers can respond better to changes in traffic conditions, improve their situational awareness, and reduce the risk of accidents.

In contrast, waiting longer intervals, such as checking mirrors only every 30 seconds or only during specific situations like changing lanes or at traffic lights, could result in missing critical information about the environment around them. This delayed awareness increases the chances of collisions and endangers both the driver and other road users. Regular mirror checks are a key component of defensive driving, promoting precaution and proactive behavior on the road.
