Difficulty: Very hardParking, Standing, and Stopping Regulations

A driver is parking a motor vehicle facing uphill on a steep roadway bordered by a raised concrete curb. Which procedure correctly describes how the front wheels must be positioned and secured to prevent the vehicle from rolling into moving traffic if the parking brake fails?

  1. Turn the front wheels away from the curb (to the left) and allow the vehicle to roll back slightly until the back of the front tire gently contacts the curb.Answer
  2. B
    Turn the front wheels toward the curb (to the right) so that the front edge of the tire rests firmly against the curb line.
  3. C
    Keep the front wheels pointed straight ahead while relying exclusively on placing the transmission in gear or Park along with engaging the parking brake.
  4. D
    Turn the front wheels away from the curb (to the left) while maintaining a gap of at least twelve inches between the tire and the curb surface.

Answer

Turn the front wheels away from the curb (to the left) and allow the vehicle to roll back slightly until the back of the front tire gently contacts the curb.
When parking facing uphill where a raised curb is present, turning the front wheels away from the curb (to the left) and letting the vehicle roll back until the tire touches the curb ensures that the curb acts as a block. If the brakes fail, the vehicle's roll is immediately stopped by the curb rather than coasting into the roadway.

Step-by-Step Solution

1
Determine the orientation of the vehicle and the presence of a curb.
The vehicle is facing uphill on a street with a raised curb.
Wheel turning direction rules depend specifically on whether the vehicle faces uphill or downhill and whether a raised curb is present.
2
Select the correct steering wheel direction for uphill parking with a curb.
Turn the steering wheel to the left (away from the curb).
If the vehicle rolls backward down the incline, the front tires will pivot so that the back of the front tire faces the curb.
3
Execute the securing maneuver with the curb.
Allow the vehicle to roll back slowly in neutral until the tire makes gentle contact with the curb, then set the parking brake and shift into Park (or reverse/first gear for manual).
Physical contact with the curb prevents momentum build-up and uses the curb as a mechanical chock.
