How often should a driver check their mirrors while driving?

The correct answer emphasizes the importance of maintaining situational awareness while driving. Checking mirrors frequently, or every few seconds, allows drivers to monitor their surroundings, including the positions of other vehicles, cyclists, and pedestrians. This practice helps in making informed decisions, such as when to change lanes or react to potential hazards. By keeping an eye on the rear and side mirrors, drivers can better anticipate actions of other road users, which is essential for safe driving.

Frequent mirror checks contribute significantly to overall safety by reducing blind spots and reinforcing the concept of defensive driving, where drivers are aware of potential risks around them. This habitual checking becomes particularly critical in dynamic driving environments, where traffic conditions can change rapidly.

The other response options do not support adequate situational awareness. Checking mirrors every minute or only during lane changes or at intersections would result in gaps in awareness that could lead to dangerous situations. Regular mirror checks are a fundamental aspect of safe driving practices.
