Which cars are hidden in the truck's blind spots?

Trucks have large blind spots, called No-Zones. A car traveling in a No-Zone may be completely hidden from the truck driver's view. The truck's side mirrors provide only small arcs of visibility down the sides of the truck. A vehicle that is right behind the truck or to the side of the truck, just behind the cab may be in a No-Zone. Here, Car B is in one of the truck's No-Zones. It is impossible to always avoid a truck's No-Zones, but don't remain in its No-Zones any longer than absolutely necessary.
