When passing another vehicle with a long combination, when is it safe to return to your lane?
- A.As soon as your tractor is ahead of the other vehicle
- B.When the other driver flashes their lights, whatever your mirrors show
- C.After a fixed count of three seconds
- D.Only when you can see the passed vehicle's front in your mirrors with room to spare, remembering the full length that must clear it
Correct answer
D. Only when you can see the passed vehicle's front in your mirrors with room to spare, remembering the full length that must clear it
Why
The maneuver is not finished when the cab passes; it is finished when the last trailer clears. Mirror confirmation of the passed vehicle's front is the reliable signal that the whole outfit has room.
