Most fatalities involving trucks are usually caused by drivers in the vicinity of trucks, not the route driver, reports According to the AAA Foundation for Truck Safety, university studies and other research, motorists may be operating recklessly or inattentively around trucks. Speed limits may be a big reason for that. The Governor’s Highway Safety Association (GHSA) showed that 38 jurisdictions of 50 responding to a survey said that speed limits in those areas had increased since 1994 despite efforts to keep speeds at 65 mph in rural areas and 55 mph on urban roads. Thirty-one states have raised speed limits to 70 mph or higher on some portion of their roadways. After a repeal of the National Maximum Speed Limit 10 years ago, a 1999 study reported that highway deaths increased 15 percent in 24 states the raised their speed limits. Those surveyed by the GHSA showed that 42 of the 50 jurisdictions felt comfortable with a “cushion” of 5 to 10 mph over the speed limit, including those enforcing the speed limit.
