Why should you allow a bigger gap when towing a trailer?

Answer and explanation

Correct answer: D. The extra weight lengthens the stopping distance of the whole combination

  1. Step 1: More mass needs more braking distance. Step 2. Increase your following gap. Answer: The extra weight lengthens the stopping distance of the whole combination. Why not the others: The trailer makes the car lighter and quicker to stop: a trailer adds weight. The trailer reduces the driver's thinking time at speed: reaction time is the driver's, not the vehicle's. The trailer improves braking grip on the rear axle: extra mass reduces the braking efficiency.
