How often should you check your rearview mirror while driving?

Regularly checking your rearview mirror every few seconds is essential for safe driving. Continuously monitoring the traffic behind you allows you to stay aware of any changes in your surroundings, including the distance and speed of vehicles approaching from behind. This practice helps you anticipate potential hazards, such as a vehicle that might attempt to overtake you or a sudden stop by the vehicle in front.

By doing so, you maintain a comprehensive understanding of your environment, which is crucial for making informed decisions about speed adjustments, lane changes, and overall vehicle control. Such vigilance contributes to greater safety for all road users, ensuring that you are prepared for any unexpected developments. This habit is an integral part of defensive driving, enabling you to respond promptly and effectively to emergencies.
