As we have discussed before, speeding is a major cause of 18-wheeler accidents. It’s the number one cause of deadly tractor-trailer crashes, according to a federal government study based on 2017 statistics. The 2015 South Carolina Commercial Driver’s License Manual spells out in stark detail why speed can kill in a semi-trailer crash. Bear in mind, all truckers study this manual so they can qualify for their license to drive these monster machines—so we know they know this stuff.
The manual makes clear bringing these behemoths to a stop is a matter of distance, speed, and weight.
Stopping distance is a combination of three separate distances, measuring how fast the truck travels between the point there is a reason to stop and the point the vehicle actually comes to rest. Remember, these distances are under ideal conditions:
Total stopping distance. Adding all this up under the best of conditions, it takes a semi moving at 55 mph a stunning 419 feet to stop.
For full effect, the manual reminds truckers the faster they drive, the worse the impact. It also tells them slowing down reduces braking distance. Then it makes abundantly clear how speed endangers us all: at 60 mph, stopping distance is greater than the length of a football field. At 80 mph, braking distance is 16 times higher than at 20 mph.
The manual instructs truckers they should always drive at a speed enabling them to stop the tractor-trailer in the distance they can see ahead. Fog, rain, or other conditions may require slowing down to meet this requirement. And driving at night with low headlight beams requires slowing down.
Believe it or not, it’s harder to stop an empty truck. This is because 18-wheeler brakes are designed to perform best on a fully loaded vehicle. Kudos to the designers of these brake systems who realized the most important safety system for the vehicle should be geared towards its most typical use.
