Answer options

  2. BJudge how many seconds it might take you to close the gap to the vehicle in front
  3. CGuess how many truck lengths would fit in the space up to the vehicle in front

Why

Pick a fixed point such as a sign or an overpass; when the rear of the vehicle ahead passes it, count the seconds until your front end reaches it. A large vehicle should keep at least one second for every 10 feet of its length, plus one more second at speeds above 40 mph.
