Question #15
You are driving a 60 foot truck at 55 MPH, how much space (in seconds) should you keep in front of you?
- A5 seconds
- B6 seconds
- C7 seconds
- D8 seconds
Correct Answer:
C
The correct answer is: 7 seconds. To calculate your space required, use the following formula: If going under 40 MPH, use 1 second for each 10' of vehicle length.
If going over 40 MPH, use the same formula but add 1 second. In this scenario, a 60' truck requires 6 seconds, but you need to add an additional second, because you are travelling over 40 mph. So the correct answer is 7 seconds.
