MO DMV Sharing the Road 3 — Questions and Answers
Question 1: Why do large trucks need a longer distance to stop than passenger cars?
- Their greater weight increases stopping distance (Correct answer)
- Their brakes are weaker by design
- Truck drivers react more slowly
- Their tires have less traction than car tires
Correct answer: Their greater weight increases stopping distance
A loaded truck's mass requires significantly more distance to stop, especially at highway speeds.
Question 2: You want to pass a large truck on the interstate. What is the safest approach?
- Pass on the left, move through the blind spot quickly, and return only when the whole truck is visible in your mirror (Correct answer)
- Pass on the right where the truck driver expects you
- Pass slowly to stay predictable
- Pass and immediately merge back in front of the truck
Correct answer: Pass on the left, move through the blind spot quickly, and return only when the whole truck is visible in your mirror
Pass on the left without lingering in the blind spot, and wait until you can see the entire truck in your rearview mirror before merging back.
Question 3: A motorcycle ahead of you is approaching a patch of gravel on the road. What should you expect?
- The rider may slow down or change position within the lane (Correct answer)
- The rider will speed up to cross it quickly
- The rider will pull onto the shoulder
- The gravel will not affect the motorcycle
Correct answer: The rider may slow down or change position within the lane
Surface hazards like gravel are dangerous for motorcycles, so riders often adjust speed or lane position to avoid them.
Question 4: When is a bicyclist allowed to ride in the middle of a travel lane?
- When the lane is too narrow to share safely or hazards exist near the edge (Correct answer)
- Never; bicycles must always stay on the shoulder
- Only during daylight hours
- Only when riding in groups of three or more
Correct answer: When the lane is too narrow to share safely or hazards exist near the edge
Bicyclists may take the full lane when it is too narrow to share side by side or when avoiding edge hazards like debris or parked cars.
Question 5: You see a pedestrian with a white cane waiting at a corner. What does this indicate?
- The person is blind or visually impaired and you must yield to them (Correct answer)
- The person is directing traffic
- The person needs vehicle assistance
- The person is a crossing guard
Correct answer: The person is blind or visually impaired and you must yield to them
A white cane or guide dog identifies a blind or visually impaired pedestrian who always has the right-of-way.
Question 6: Missouri's Move Over law requires you to do what when approaching a stopped emergency vehicle with flashing lights?
- Move into a lane away from the vehicle if possible, or slow down if you cannot (Correct answer)
- Stop completely on the roadway
- Flash your headlights and continue at the same speed
- Honk and change lanes only if an officer waves you over
Correct answer: Move into a lane away from the vehicle if possible, or slow down if you cannot
You must change lanes away from stopped emergency vehicles when safe, or slow down significantly if changing lanes is not possible.
Question 7: When driving near a slow-moving farm vehicle displaying an orange triangle emblem, you should:
- Slow down and pass only when it is safe and legal (Correct answer)
- Follow closely to encourage it to pull over
- Honk continuously until it moves aside
- Pass immediately on the right shoulder
Correct answer: Slow down and pass only when it is safe and legal
The orange triangle marks a slow-moving vehicle, so reduce speed and wait for a safe, legal opportunity to pass.
