Your combination vehicle is 50 feet long, and you are cruising at 50 mph in good conditions. At a minimum, how many seconds of following distance do you need?

Answer options

Why

The rule calls for one second for each 10 feet of vehicle length, plus one more second at speeds above 40 mph. A 50-foot rig at 50 mph therefore needs 5 + 1 = 6 seconds, and even more when the road or weather is poor.
