Car drivers should know that large trucks:
- Have large blind spots. ✓
- Can stop more quickly than passenger vehicles.
- Do not need more room to maneuver than passenger vehicles.
- All of the above.
Answer: A. Have large blind spots.
Large trucks have large blind spots.
Why this is the answer
The handbook passage about sharing the road with tractor-trailers tells you to stay out of a truck's blind spot behind it. It explains that the blind spot is the area behind the truck that the driver cannot see in the rearview mirrors. The passage also advises positioning your vehicle so the truck driver can see you in the side mirror. This directly supports the statement that large trucks have large blind spots. The same passage notes that tractor-trailers take longer to stop than a car, which shows why the other choices are wrong.
Why the other answers are wrong
- B. Can stop more quickly than passenger vehicles. — The passage says tractor-trailers take longer to stop than a car traveling at the same speed, so they cannot stop more quickly.
- C. Do not need more room to maneuver than passenger vehicles. — The passage does not state that trucks need the same room to maneuver; it focuses on blind spots and longer stopping distance, and does not support this claim.
- D. All of the above. — This is wrong because the statement about stopping more quickly is contradicted by the passage, and the maneuvering room claim is not supported, so not all of the above are true.
Remember it
If you can't see the truck driver in the side mirror, the driver can't see you.
