Effect of weight on braking for trucks.

Let's see, 85-62 is 23. Is it your opinion that most drivers can not miss a stopped car on a 4 lane road when driving 23 MPH? And the fault is the slow drivers?

It’s not about fault. It’s about increasing the chance of being in an accident.

According to state and federal studies, drivers that are driving significantly below the average speed are the ones that are most likely to get involved in an accident. Studies show that the most accidents occur when the driver is driving at 10 mph slower than the speed limit. So someone going 45 in a 55 has a bigger chance of getting into an accident than someone driving at 65-70 mph.

The main problem on roads that causes accidents is the differences in speed, rather than speed itself. While some people are going faster than other, some go slower which causes the traffic to flow unevenly. If the speeds limits are raised to comply with the actual travel speeds, the roads become safer, because the traffic now flows more evenly and people start going to the same speeds. This actually shows that drivers are not affected by the speed limits that much, but rather slow drivers. The National Highway Traffic Safety Administration (NHTSA) Says that only 30% of the accidents that are fatal are accidents in which the driver was speeding. This does not mean that the speeding actually is the cause of the accident. A study conducted by the Florida Department of Transportation says that accidents that were caused by speeding is actually 2.2%. This shows that if people drive faster all together it is actually safer than driving slow.
