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 — the handbook warns against driving so slowly that you block normal, reasonable traffic flow.
Why this is the answer
The handbook says you must slow down in heavy traffic or bad weather, but it also tells you not to hold up normal, reasonable traffic flow by going too slowly. It adds that driving faster or slower than the speed limit can get you cited, and that if you want to drive slower than other traffic you should use the right lane. That makes a too-slow driver a real problem on a highway, which is why the statement about slow driving being dangerous on certain highways is the one that is true.
Why the other answers are wrong
- A. Driving too slowly is not an unsafe practice. — The handbook treats driving too slowly as a problem, since it says not to block normal traffic flow and that going slower than the speed limit can get you cited.
- C. The speed at which you drive a vehicle does not affect safety. — The handbook ties speed directly to safety, telling drivers to slow down in bad weather or heavy traffic and warning that driving too slowly can block traffic.
Remember it
Slow is not automatically safe: if cars are piling up behind you, move to the right lane.
