What is a "blind spot" and why is it significant for truck drivers?

A "blind spot" refers to areas around a truck that are not visible to the driver through the mirrors. This is significant for truck drivers because these blind spots can hide vehicles, cyclists, or pedestrians that are nearby, increasing the risk of collisions. Being aware of the location and size of these blind spots is crucial for safe driving. It highlights the importance of checking these areas before changing lanes or making turns, as failing to do so can lead to serious accidents. Understanding and managing blind spots effectively helps ensure the safety of both the truck driver and other road users.
