NC DMV Sharing the Road 3 — Questions and Answers
Question 1: Why do large trucks need a longer distance to stop than passenger cars?
- Their brakes are weaker by design
- Their greater weight increases stopping distance (Correct answer)
- Truck drivers react more slowly
- Their tires have less traction
Correct answer: Their greater weight increases stopping distance
A loaded truck's much greater weight means it needs significantly more distance to come to a complete stop.
Question 2: A motorcycle ahead of you is approaching a metal bridge grating. What should you expect the rider to do?
- Speed up to cross quickly
- Slow down or change lane position (Correct answer)
- Stop completely before the bridge
- Ride on the shoulder
Correct answer: Slow down or change lane position
Riders often slow down or adjust position because metal gratings and uneven surfaces reduce motorcycle traction and stability.
Question 3: You want to pass a large truck on the highway. Which side should you pass on?
- The right side, where the lane is wider
- Either side is equally safe
- The left side, and complete the pass quickly (Correct answer)
- Whichever side has less traffic
Correct answer: The left side, and complete the pass quickly
The truck's right-side blind spot is much larger, so always pass on the left and clear the blind spot without lingering.
Question 4: A blind pedestrian carrying a white cane is waiting at a corner. What must you do?
- Wave them across
- Yield the right-of-way to the pedestrian (Correct answer)
- Sound your horn to guide them
- Proceed slowly around them
Correct answer: Yield the right-of-way to the pedestrian
Drivers must always yield to pedestrians using a white cane or guide dog.
Question 5: When following a truck downhill on a steep grade, why should you increase your following distance?
- Trucks accelerate rapidly downhill and pull away
- The truck may need to brake often and could roll back or stop suddenly (Correct answer)
- Trucks always use the shoulder downhill
- Your car brakes work worse behind a truck
Correct answer: The truck may need to brake often and could roll back or stop suddenly
Trucks control speed with heavy braking on downgrades and may slow or stop unexpectedly, so extra space is essential.
Question 6: You see a slow-moving vehicle emblem (orange triangle) on a vehicle ahead. What does it indicate?
- The vehicle is turning left
- The vehicle travels at 35 mph or less (Correct answer)
- The vehicle is carrying hazardous materials
- The vehicle is a student driver
Correct answer: The vehicle travels at 35 mph or less
The orange triangle marks vehicles like farm equipment that travel at 35 mph or less.
Question 7: A moped is traveling in your lane ahead of you. How should you treat it?
- As a pedestrian
- As a full vehicle entitled to use the lane (Correct answer)
- As an obstacle you may pass within the same lane
- As a vehicle that must ride on the shoulder
Correct answer: As a full vehicle entitled to use the lane
Mopeds are legal road vehicles entitled to the full lane, and you must pass them as you would another vehicle.
