Which of the following is true about large trucks?
- They are made of many trailers, which make them more maneuverable than passenger vehicles.
- They have large blind spots, which makes it difficult for the truck driver to see other vehicles. ✓
- They have large and powerful emergency brakes, which gives them the capability to stop quickly.
Answer: B. They have large blind spots, which makes it difficult for the truck driver to see other vehicles.
Large trucks have large blind spots, so the truck driver often cannot see other vehicles around them.
Why this is the answer
The handbook says truck drivers have a good view ahead and big mirrors, but they still have large blind spots it calls No Zones, where your vehicle can vanish from the driver's view. It gives a simple test: if you cannot see the truck's side mirrors, the driver cannot see you. That is why the statement about blind spots is the true one, and it is also why you should not linger beside a truck.
Why the other answers are wrong
- A. They are made of many trailers, which make them more maneuverable than passenger vehicles. — The handbook says large vehicles and trucks are not as easy to maneuver as passenger vehicles, so having trailers does not make them more maneuverable.
- C. They have large and powerful emergency brakes, which gives them the capability to stop quickly. — The handbook states that large vehicles and trucks take longer to stop than passenger vehicles at the same speed, so they cannot stop quickly.
Remember it
Ask yourself one question around any big rig: can I see the driver's mirror? If not, the driver has no idea you are there.
