How often should drivers check their mirrors?

Drivers should check their mirrors continuously while driving to maintain situational awareness and safety on the road. This practice allows drivers to monitor the position and speed of vehicles behind and beside them, making it easier to react appropriately to changing traffic conditions. By keeping an eye on their surroundings, drivers can better anticipate potential hazards, such as vehicles attempting to merge, pedestrians crossing, or other unexpected occurrences.

Relying on mirror checks only during specific times, like changing lanes, may lead to dangerous situations because drivers would be less aware of their surroundings in between those checks. Similarly, checking mirrors every few minutes or only at the beginning of a trip does not provide the constant awareness needed for safe driving. Continuous monitoring supports proactive decision-making and helps prevent accidents, making it a crucial habit for all drivers.
