Imagine you are driving the blue car behind the red one. Which following distance gives you a safe cushion?
Correct answer: A cushion of at least 3 seconds.
Answer options
AA 1-second cushion
BA cushion of at least 3 seconds Correct
CA half-second cushion
Why
Indiana's manual advises staying at least two to three seconds behind the vehicle ahead, so a cushion of at least 3 seconds meets that rule, while a gap of a second or less is tailgating. To check it, count from when the red car passes a fixed point until you reach that point, and add time in poor conditions.
