How frequently should drivers check their rear-view mirrors while driving?

Checking rear-view mirrors every 10 seconds is essential for safe driving. This practice allows drivers to remain aware of their surroundings and the traffic situation behind them, which is crucial for making informed decisions. Regularly monitoring the rear-view mirrors helps in assessing the speed and distance of vehicles approaching from behind, detecting potential hazards, and ensuring that any changes in traffic patterns are noticed promptly. Therefore, maintaining this frequency supports the overall goal of driving defensively and helps prevent accidents by keeping drivers informed about their environment.
