IIHS says speed limit increases since 1993 responsible for 36,760 extra deaths
Research studies have shown that higher speed limits lead to more road accidents. In one study, the Insurance Institute for Highway Safety found that states that increased their speed limits saw a 3% rise in fatalities on interstates and freeways. The study also found that the number of fatal crashes involving speeding rose by 5%. Other studies have shown similar results. A study by the National Highway Traffic Safety Administration found that speed was a factor in nearly one-third of all fatal crashes in the United States. The study also found that speeding contributes to nearly half of all traffic fatalities in rural areas. The results of these studies show that higher speed limits and increased traffic volume can lead to more accidents.
