what are large blind spots on trucks called?
If you cannot see the truck driver's reflection in his or her side mirror, you are in the truck driver's blind spot and they cannot see you. If you stay in those blind spots, you block the trucker's ability to take evasive action to avoid a dangerous situation. A truck's blind spots are called No Zones. A No Zone is the area around the trucks where your car is no longer visible or you are so close that the truck can't stop or maneuver safely. In both cases, when you are in a No Zone you are in much greater danger of getting into a collision.
