How often should drivers check their rear-view mirrors?

Drivers should check their rear-view mirrors every 5-10 seconds while driving to maintain situational awareness and ensure a safe driving environment. This practice allows drivers to monitor the traffic behind them, be aware of any approaching vehicles, and prepare for any potential hazards that may arise.

Frequent rear-view mirror checks help in making informed decisions about lane changes, turns, and other maneuvers, contributing to overall road safety. By adopting this regular checking routine, drivers can avoid accidents caused by blind spots and can react promptly to changing traffic conditions. This interval strikes a balance between maintaining focus on the road ahead and being aware of what's happening behind, which is critical for defensive driving.
