What does the term "no zone" refer to in truck driving?

The term "no zone" specifically refers to the blind spots around a commercial vehicle where the driver cannot see other vehicles or objects. These blind spots are critical areas of concern for truck drivers, as they can lead to accidents if other vehicles are not visible when the truck is changing lanes or making turns. Understanding and identifying these no zones is essential for safe driving, as it helps both truck drivers and other motorists maintain awareness of their surroundings. Being cautious around these blind spots is vital to ensure safety on the road, particularly given the size and length of commercial vehicles compared to standard cars. This knowledge encourages drivers to stay out of these areas to minimize the risk of collisions.
