Difficulty: MediumParking, Standing, and Stopping Regulations

A motorist is securing a vehicle parked facing uphill on a two-lane road that does not have a curb along the shoulder. To prevent the vehicle from rolling into traffic in the event of brake failure, in which direction should the front wheels be turned?

  1. To the right, toward the shoulder or edge of the roadAnswer
  2. B
    To the left, toward the center of the roadway
  3. C
    Straight ahead, keeping the tires parallel with the road edge
  4. D
    In whatever direction the tires rest after engaging the parking brake

Answer

The front wheels should be turned to the right, toward the shoulder or edge of the road.
When parking uphill on a roadway without a curb, turning the front wheels to the right ensures that if the vehicle begins rolling backward, the rear of the vehicle will roll away from the road surface and onto the shoulder.

Step-by-Step Solution

1
Identify the grade of the road and the presence or absence of a curb.
The vehicle is facing uphill on a road with no curb.
Proper wheel placement depends on whether a raised curb exists to stop the tires.
2
Determine which direction the vehicle would roll if the brakes fail and choose the wheel position that directs it away from traffic.
Turning the front wheels to the right ensures the vehicle rolls off the roadway onto the shoulder if it moves backward.
Without a curb to catch the front tire, turning wheels to the left would cause a backward-moving vehicle to curve directly into active traffic lanes.
