Practice question

Why are large trucks’ blind spots called no-zones?

  1. Because drivers cannot see other vehicles in those areas, increasing crash risk; avoid lingering in them.
  2. They are places where you can safely ride alongside.
  3. They are designated safe zones.
  4. They are zones behind the truck only.

Answer: A — Because drivers cannot see other vehicles in those areas, increasing crash risk; avoid lingering in them.

These areas are called no-zones because a truck driver cannot see vehicles that are in those spots, which makes crashes more likely if you linger there. Large trucks sit high and are long, and their mirrors don’t show every angle, so the zones directly alongside, behind, and sometimes in front of the truck can be out of the driver’s view. If you’re in a no-zone, the truck may change lanes, brake, or turn without the driver seeing you in time. The safest behavior is to avoid staying in these zones, pass or merge quickly when needed, and keep a clear, steady position so the truck driver can see you and react appropriately.
