Why is it important to periodically check your mirrors?

Answer: B — To maintain awareness of surrounding traffic

The correct choice emphasizes the necessity of maintaining awareness of surrounding traffic. Periodically checking your mirrors is crucial for safe driving as it helps you stay informed about other vehicles, pedestrians, and potential hazards around you. This practice enhances your situational awareness, allowing you to react promptly to changes in the driving environment. By regularly monitoring your mirrors, you can keep track of approaching vehicles, notice any sudden lane changes, and ensure that you have enough space when merging or changing lanes. This increased awareness reduces the likelihood of accidents and contributes to safer road conditions for everyone. Regular mirror checks are a fundamental aspect of defensive driving, which prioritizes prevention and caution on the road.
