Which of the following statements are true about sharing the road with large trucks?
- Large trucks have shorter stopping distances.
- Large trucks create heavy turbulence that may affect your ability to control your motorcycle. ✓
- Stay in the left lane if a large truck ahead is making a left turn.
- All of the above statements are true.
Answer: B. Large trucks create heavy turbulence that may affect your ability to control your motorcycle.
The true statement is that large trucks create heavy turbulence that may affect your ability to control your motorcycle.
Why this is the answer
The handbook says passing a large vehicle on a motorcycle is difficult and can be dangerous. It explains that air pressure and airflow from the larger vehicle can create heavy turbulence. That turbulence can seriously affect your ability to control your motorcycle while you are passing. The handbook tells you to relax and work with the air, leaning away from the truck if you are being pulled toward it, or leaning toward it if you are being pushed away. This directly supports the statement about turbulence affecting control.
Why the other answers are wrong
- A. Large trucks have shorter stopping distances. — The passages do not say large trucks stop in a shorter distance; they discuss only the air turbulence a large vehicle creates, so this statement is not supported.
- C. Stay in the left lane if a large truck ahead is making a left turn. — The passages deal with passing a large vehicle and the turbulence you meet, not with staying in the left lane when a truck ahead is turning left, so this advice is not supported.
- D. All of the above statements are true. — This cannot be right because the statement about shorter stopping distances and the left-lane turning advice are not supported, even though the turbulence statement is.
Remember it
Think of truck air as a push or pull: relax, then lean away from a pull and toward a push.
