When should a commercial driver be especially cautious about blind spots?

A commercial driver should be especially cautious about blind spots at all times, particularly during lane changes or merging. Blind spots are areas around a vehicle that cannot be easily seen by the driver through mirrors or direct line of sight. These zones can be significant for large commercial vehicles, which often have larger blind spots compared to smaller vehicles.

When changing lanes or merging, the risk of collisions increases if the driver does not adequately check blind spots. This is essential for ensuring the safety of all road users, as other vehicles, especially those that are smaller, can easily be in a blind spot. It is important for drivers to utilize mirrors effectively and, when safe, to turn their heads to check these areas thoroughly before making maneuvers.

Being cautious in blind spots is not limited to specific conditions such as urban driving or when carrying a full load. Instead, it is crucial for commercial drivers at all times to mitigate the risks associated with limited visibility. Proper training emphasizes the need for awareness in relation to blind spots and encourages vigilant observation practices to enhance road safety.
