Final answer:
If the motorist of a large truck or bus cannot see you in his rearview or side-view mirrors, you are in their blind spot or 'no-zone.'
Step-by-step explanation:
If the motorist of a large truck or bus cannot see you in his rearview or side-view mirrors, you are in their blind spot or 'no-zone.' These blind spots are areas around the vehicle where the driver's view is limited or obstructed.
It is important for pedestrians and drivers of smaller vehicles to be aware of these blind spots and avoid lingering in them. Some examples of blind spots include directly behind the vehicle, along the sides just behind the side-view mirrors, and a significant distance behind the vehicle's rear bumper.
