Vehicle Safety, Documents & TowingStandalone practice
You are pulling a loaded utility trailer behind your pickup on a dry, clear highway. You keep the same three-second gap that you use without the trailer. Is that gap right?
Correct answer: It may be too short, because the added weight makes your stop take longer
Why
Extra weight makes a vehicle take longer to stop, so the basic three-second gap can leave too little room. To check the gap, note when the vehicle ahead passes a sign or pole and count the seconds until you reach it; if you get there too soon, drop back and count again. The manual also advises extra space behind motorcycles and emergency vehicles, near railroad crossings and when you are stopped on a hill.
