Final answer:
The 'no zone' is the area around a truck where the driver cannot see other vehicles due to blind spots, which increases the risk of collision.
Step-by-step explanation:
The area around all four sides of a truck where the truck's driver cannot see other vehicles, commonly known as the truck's blind spots, is referred to as the "no zone." This term is important for all drivers to understand as it represents zones where if a car is present, the truck driver will be unable to see it using mirrors alone. Being in the no zone can increase the risk of a collision because the truck driver may make a move without being aware of the car's presence.
The area around all four sides of a truck where the truck's driver cannot see you is called the "no zone" or blind spots from side-view mirrors. These are areas where the driver's line of sight is blocked by the truck's design or by other vehicles.
