NC DMV Vehicle Operation and Control 1 — Questions and Answers
Question 1: When approaching a steep downhill grade, what should you do to safely control your vehicle?
- Shift into a lower gear and use the brakes lightly (Correct answer)
- Shift into a higher gear and accelerate slightly
- Use only the brakes to maintain a constant speed
- Maintain your speed and rely on the automatic transmission
Correct answer: Shift into a lower gear and use the brakes lightly
When approaching a steep downhill grade, you should shift into a lower gear to engage engine braking, which helps control your speed without relying solely on your friction brakes. Additionally, apply the brakes lightly and intermittently to maintain a safe speed and prevent them from overheating, ensuring you retain braking power.
Question 2: What should you do if your vehicle begins to skid on a slippery road?
- Steer in the direction of the skid and pump the brakes
- Steer in the opposite direction of the skid and apply the brakes hard
- Steer in the direction of the skid and gently ease off the accelerator (Correct answer)
- Immediately turn the wheel sharply to regain control
Correct answer: Steer in the direction of the skid and gently ease off the accelerator
If your vehicle begins to skid on a slippery road, the correct response is to steer gently in the direction you want the front of the vehicle to go (the direction of the skid) and gently ease off the accelerator. Avoid braking harshly or making sudden steering movements, as this can worsen the skid and cause you to lose control completely.
Question 3: How should you use your mirrors to ensure safe lane changes?
- Check your mirrors briefly and change lanes quickly
- Only use your side mirrors to check for traffic
- Check your mirrors, use your turn signal, and check over your shoulder (Correct answer)
- Use your rearview mirror and change lanes without signaling
Correct answer: Check your mirrors, use your turn signal, and check over your shoulder
To ensure safe lane changes, drivers should follow a three-step process: first, check your rearview and side mirrors for traffic; second, activate your turn signal to alert other drivers of your intention; and third, perform a quick head check (shoulder check) to verify no vehicles are in your blind spot. This comprehensive approach minimizes the risk of collisions during a lane change.
Question 4: What is the correct procedure for parallel parking?
- Pull up alongside the parked car, turn the wheel sharply, and back into the space
- Stop next to the parking space, shift into reverse, and back straight into the space
- Pull up even with the parking space, turn the wheel sharply, and back into the space while adjusting as needed (Correct answer)
- Drive past the parking space, then reverse into it
Correct answer: Pull up even with the parking space, turn the wheel sharply, and back into the space while adjusting as needed
The correct procedure for parallel parking involves aligning your vehicle with the car in front of the desired space. You then turn your wheel sharply to back into the space, using your mirrors and making small adjustments to maneuver safely between the parked cars and the curb. This method ensures proper positioning and avoids collisions.
Question 5: What is the purpose of using cruise control while driving?
- To increase your speed on downhill slopes
- To maintain a constant speed without keeping your foot on the accelerator (Correct answer)
- To ensure you stay within the speed limit automatically
- To help you accelerate quickly when merging onto the highway
Correct answer: To maintain a constant speed without keeping your foot on the accelerator
Cruise control is a feature designed to maintain a consistent vehicle speed automatically. By setting a desired speed, drivers can remove their foot from the accelerator pedal, which helps reduce fatigue on long journeys. It also contributes to better fuel efficiency by preventing frequent speed fluctuations.
