Which statement about speed is true?
- Driving too slowly on certain highways can be dangerous.
- Speeding can kill.
- Speeding is not dangerous if you are a skilled driver.
- Both "Driving too slowly on certain highways can be dangerous" and "Speeding can kill." ✓
Answer: D. Both "Driving too slowly on certain highways can be dangerous" and "Speeding can kill."
The true statement is the one that includes both warnings: driving too slowly on certain highways can be dangerous, and speeding can kill.
Why this is the answer
The handbook says that driving slower than a minimum speed can hold up traffic and create a dangerous condition, and that slow drivers can be as dangerous as fast ones. It also says you must obey the speed limit and keep your actual speed safe for conditions. Those passages support the paired answer: the slow-driving warning is stated directly, and speeding is treated as a serious danger even though these lines do not use the word kill.
Why the other answers are wrong
- A. Driving too slowly on certain highways can be dangerous. — This is a true statement from the handbook, but by itself it leaves out the other true point about the danger of speeding.
- B. Speeding can kill. — This is also treated as true, but alone it misses the handbook's warning that driving too slowly can create a dangerous condition.
- C. Speeding is not dangerous if you are a skilled driver. — The handbook says to obey the speed limit and choose a safe speed for conditions; it gives no exception for skilled drivers.
Remember it
When an answer pairs two warnings, check both halves before choosing only one of them.
