Difficulty: MediumParking, Standing, and Stopping Regulations

A motorist is parking a vehicle facing downhill on a road equipped with a raised sidewalk curb. To ensure the vehicle is safely secured and will roll into the curb rather than into oncoming traffic if the parking brake slips, in which direction should the driver turn the front wheels?

  1. Toward the curb or right shoulder of the roadAnswer
  2. B
    Away from the curb toward the center of the road
  3. C
    Straight ahead in line with the roadway edge
  4. D
    Toward the center of the street until the rear of the front tire touches the curb

Answer

Turn the front wheels toward the curb or right shoulder of the road.
When parked facing downhill on a grade with a raised curb, turning the front wheels toward the curb ensures that if the vehicle begins to move forward due to brake failure, the front right tire will roll into and block against the curb, keeping the vehicle stationary.

Step-by-Step Solution

1
Determine the direction of the grade and presence of a curb
The vehicle is facing downhill with a raised curb on the right side.
Vehicle orientation and curb status dictate how gravity will cause the vehicle to roll if brakes fail.
2
Select the wheel position that directs rolling motion into a safe obstruction
Turning the front wheels to the right (toward the curb) ensures the front tire rolls forward and jams against the curb.
A downhill force propels the car forward; angling the wheels right directs the front tires into the curb structure to block movement.
