How often should commercial vehicle drivers check their mirrors?

Checking mirrors every 5 to 10 seconds is essential for commercial vehicle drivers as it helps maintain awareness of the surrounding environment and enhances safety on the road. The frequency of checking mirrors allows drivers to monitor traffic conditions, observe other vehicles, cyclists, or pedestrians, and react quickly to any changes. This practice is especially critical given the larger blind spots associated with commercial vehicles, which can obscure smaller vehicles that may be in close proximity.

Regular mirror checks ensure that drivers remain aware of their positioning in relation to other road users, thereby reducing the risk of collisions and accidents. This vigilance plays a crucial role in safe driving practices, particularly in urban settings or during complex traffic maneuvers. In contrast, options that suggest less frequent checks would not provide the same level of situational awareness, potentially leading to dangerous situations on the road.
