In good weather at moderate speed, what is the minimum following distance the Tennessee driver manual recommends for the blue car behind the red car?
Correct answer: At least 2 seconds.
Answer options
AHalf a second
B1 second
CAt least 2 seconds Correct
Why
Tennessee's driver manual says to stay at least 2 seconds behind the vehicle ahead in good conditions; check it by counting from when the car ahead passes a fixed object, such as a sign or pole, until you reach it. One second or half a second is far too close, and you should allow at least 4 seconds in bad weather, at night, or at higher interstate speeds.
