Passing target: 80% (40/50)
On a multilane highway, you drive on the right side of a tractor-trailer, just behind its cab. You cannot see the truck driver's face in the truck's side mirror. What does this tell you?
On a two-lane carriageway, blue A is beside white tractor-trailer B on B's right, just behind the cab. The card states that A cannot see the driver's face in the mirror.
Correct answer: The truck driver probably cannot see you, so move ahead or drop back out of this area
Why
Large trucks have no-zones on both sides, up to 20 feet in front of the cab and up to 200 feet behind. Pass a truck completely and on the left side, and do not stay beside it longer than necessary. After you pass, move back in front only when you can see the whole front of the truck in your rear-view mirror.
