How often should a driver check their mirrors while driving?

1. Only during turns

2. At regular intervals and when necessary

3. Only during the initial part of the trip

4. Once every 10 minutes

The correct answer is: At regular intervals and when necessary

A driver should check their mirrors at regular intervals and when necessary to maintain situational awareness on the road. This practice is crucial for ensuring safety as it allows the driver to monitor the positions of other vehicles, pedestrians, and any potential hazards around them. Consistent mirror checks help the driver stay aware of their surroundings, which is vital in preventing accidents and making informed decisions while driving. Regular intervals might include checking mirrors after changes in speed, merging, approaching intersections, or as traffic conditions change. It is not limited to specific moments like turns, initial trip phases, or time intervals, as those could lead to oversight of other important factors contributing to safe driving. This encompasses a proactive approach to driving that enhances safety for everyone on the road.
