Which of the following statements is true?
- Driving too slowly is not an unsafe practice.
- Driving too slowly on certain highways can be dangerous. ✓
- The speed at which you drive a vehicle does not affect safety.
Answer: B. Driving too slowly on certain highways can be dangerous.
Driving too slowly on certain highways can be dangerous — slow drivers can disrupt traffic flow and create a hazard, just like drivers who go too fast.
Why this is the answer
The handbook's defensive driving section on speed says that driving below the minimum speed can halt the flow of traffic and create a dangerous condition. It adds that even where no minimum speed is posted, people who drive too slowly can be as dangerous as those who drive too fast. That directly supports the statement that slow driving on certain highways can be dangerous, and it rules out the idea that speed has nothing to do with safety.
Why the other answers are wrong
- A. Driving too slowly is not an unsafe practice. — The handbook treats driving too slowly as a hazard that can disrupt traffic flow and be as dangerous as speeding, so it is not a safe practice.
- C. The speed at which you drive a vehicle does not affect safety. — The handbook ties speed directly to safety by saying slow drivers can be as dangerous as fast ones, so speed does affect safety.
Remember it
Think of speed as a two-sided problem: too fast and too slow both break up the flow of traffic.
