When driving 40 mph or less, what minimum following distance does the Nevada handbook recommend?
- A One second
- B One car length
- C Five seconds
- D Two seconds

- A At least 12 seconds ahead
- B Just past the car in front
- C About 3 seconds ahead
- D About 1 block, at any speed

A. At least 12 seconds ahead
Look ahead to where you will be in at least 12 seconds; at 30 mph that is a bit more than a block. On freeways, look at least 20 to 30 seconds ahead.
According to the Nevada handbook, what are normal driver reaction times?
- A 4 to 5 seconds
- B About half a second
- C 2 to 2.5 seconds
- D About 1 second
Show answer
C. 2 to 2.5 seconds
Highway safety studies show normal reaction times of 2 to 2.5 seconds, and they grow when decisions are complex. During that time your car keeps moving at full speed, which is why following distance matters.
