_________ are areas around trucks or other large vehicles in which other vehicles may disappear into blind spots.

Explanation

Don't hang out in a No-Zone! No-Zones are large areas around trucks and other large vehicles in which cars may disappear into blind spots or get so close that they restrict the truck driver's ability to stop or maneuver safely. No-Zones exist to the front, rear, and sides of the large vehicle. No-Zones greatly increase the likelihood of a crash.
