Heavier vehicles need much greater stopping distance. Trucks require a much greater stopping distance to stop than cars. The heavier the truck, the greater the distance needed to stop. Stopping distance increases substantially at higher speeds. According to the National Safety Council’s Defensive Driving Course for Professional Truck Drivers, the stopping distance for an 80,000 pound tractor trailer, traveling at 30 mph on a dry, level road, is 100 feet. If we double the speed to 60 mph, the stopping distance for that truck doesn’t double, it increases over four-fold to 426 feet. If we increase that speed another 5 mph, to 65 mph, the distance needed to stop increases almost another 100 feet, to 525 feet. This is more than 200 extra feet to stop as compared to a car. A passenger car requires 316 feet to stop at 65 mph. This is one of the reasons, trucks are involved in many rear-end collisions. Truck drivers and drivers of other vehicles need to understand the discrepancy in stopping distances between cars and trucks, and drive accordingly. When car or truck drivers fail to realize the distance needed to stop, the risk of a rear-end collision increases.
