Driving more slowly than surrounding traffic is:
- A good idea if the weather is bad.
- Appropriate if you don’t know the speed limit.
- Often a hazard because other drivers may become frustrated and try to pass you. ✓
Answer: C. Often a hazard because other drivers may become frustrated and try to pass you.
Driving more slowly than the traffic around you is often a hazard, because other drivers may get frustrated and try to pass you.
Why this is the answer
The handbook lists a vehicle traveling faster or slower than the flow of traffic among the common causes of collisions. That means going slower than everyone else puts you in the same risk category as speeding, rather than keeping you safe. The mismatch with surrounding traffic is the problem, and it matches the idea that drivers behind you may lose patience and try to get around you. Slowing down for an emergency ahead with flashers is a separate situation the handbook describes.
Why the other answers are wrong
- A. A good idea if the weather is bad. — The handbook never presents driving below the flow of traffic as a good move in bad weather; it lists travel slower than traffic as a cause of collisions.
- B. Appropriate if you don’t know the speed limit. — Nothing in the handbook says that not knowing the speed limit makes slow driving appropriate, and being unsure of the limit does not remove the mismatch with surrounding traffic.
Remember it
Think of speed as matching the flow, not beating it in either direction: too fast and too slow both show up on the collision list.
