Why is it important to mirror check frequently while driving a commercial vehicle?

Frequent mirror checks while driving a commercial vehicle are essential for maintaining awareness of surrounding traffic. Commercial vehicles are typically larger and have significant blind spots. By regularly checking mirrors, drivers can monitor the behavior of nearby vehicles, pedestrians, and any potential hazards. This practice helps in making informed decisions when changing lanes, merging, or turning, ultimately promoting a safer driving environment for both the driver and other road users. Keeping situational awareness through mirror checks is a crucial aspect of defensive driving, especially in the dynamic settings in which commercial vehicles often operate.
