A recent study in the American Journal of Health concluded that reducing speed limits for big rig trucks to 55 miles per hour on highways where cars can travel faster, will save nearly 600 lives per year. In Ohio, a bill is being debated to raise speed limits on all state highways to equal the speed that cars can travel. The trucking industry is lobbying hard for the bill, despite the fact that a two-year experiment allowing large trucks to travel as fast as cars on the Ohio Turnpike, resulted in a significant increase in truck/car crash fatalities and serious injuries. Safety advocates and the Ohio State Police are supporting current Ohio laws limiting the speed of trucks on state highways. In the majority of states, large trucks can travel at the same speed as cars – despite the solid evidence that slower truck speeds saves lives.
