When driving a truck, how far ahead should you scan, measured in seconds of travel?
Correct answer: 12 to 15 seconds.
Answer options
- A6 to 8 seconds
- B12 to 15 seconds Correct
- C1 to 2 seconds
Why
Commercial drivers should look 12 to 15 seconds ahead, roughly one block at city speeds and about a quarter mile at highway speeds. Looking that far down the road gives the driver of a large, slow-stopping vehicle time to spot problems and change lanes or slow down smoothly.
