What does it mean when a driver looks in the mirror for more than two seconds?

When a driver looks in the mirror for more than two seconds, it suggests a lapse in the natural flow of driving, which can indicate that the driver is not maintaining proper awareness of their surroundings. Extended gaze into the mirror may suggest that the driver is not focused on the road ahead and is potentially missing other critical cues from the environment, such as changes in traffic conditions, pedestrians, or road obstacles.

This behavior can lead to impaired reaction times and an increased risk of accidents, making it essential for drivers to keep their mirror checks brief and to integrate them seamlessly into their driving routine. It also highlights the importance of situational awareness, which is crucial for safe driving; thus, prolonged mirror observation can signify a problem with observation skills even if it was intended for safety prior to a lane change.
