    • Stop in the middle of the intersection
    • Turn from the left lane only

    • Not until the truck or bus has completed its turn
    Show answer

    If a driver tries to get between the truck or bus and the curb, the vehicle can be squeezed and suffer a serious crash, so do not turn until the truck or bus has completed its turn.

    • On the left side of the lane

    • Turn left once its driver waves you on

  17. What do stop lines at many intersections help give larger vehicles?

    Top view of a four-way city intersection with red traffic lights: a tractor-trailer with a blue cab is stopped behind the white stop line at the bottom, and the blue car is stopped at its line on the left.
    • Longer green signals
    • More turning space
    • Shorter stopping distances
    • A separate turning lane
    Show answer

    Correct answer: More turning space

    Stop lines help to set a vehicle farther back at an intersection to give larger vehicles more turning space, so drivers should always stop behind them.
