Minnesota Blue Card Practice Test

For safe driving, how often should a driver check their mirrors?

1. Every 5 seconds

2. Every 10 seconds

3. Every 15 seconds

4. Every 20 seconds

The correct answer is: Every 10 seconds

It is generally recommended that drivers check their mirrors every 10 seconds while driving. This practice helps to maintain situational awareness on the road, allowing drivers to monitor their surroundings effectively, including the positions of other vehicles, potential hazards, pedestrians, and changes in traffic conditions. Checking mirrors at this interval allows for timely reactions to any developments, such as anticipating lane changes, merging traffic, or responding to emergency situations. Regular mirror checks contribute to safer driving habits, helping to reduce the risk of accidents and ensuring that the driver is well-informed about their environment. Other intervals for checking mirrors, like every 5, 15, or 20 seconds, may not provide the same level of situational awareness. An interval that's too short, such as every 5 seconds, can lead to distractions, while longer intervals may result in critical information being overlooked during crucial moments. Thus, a 10-second interval strikes a balance between attentiveness and safe driving practices.
