What are a truck's blind spots called?

A truck's blind spots are commonly referred to as "no zones." These areas are located around the front, sides, and rear of the truck where the driver has limited visibility. No zones can pose significant risks for other vehicles, especially smaller ones, as they may not be seen by the truck driver when changing lanes or making turns. It's crucial for drivers to be aware of these blind spots to ensure safe maneuvering around large trucks.
