States have been raising the maximum speed limit since the national 55 mph limit — which was set be the federal government in 1973 — was repealed in 1995. According to recent data from the Insurance Institute for Highway Safety (IIHS), none of the 50 states has a maximum speed limit at 55 miles per hour (mph). Hawaii has the lowest at 60 mph and Texas has the highest at 85 mph. Twenty states have theirs set at 70 mph and, in New Jersey, the maximum speed limit is 65 mph. The IIHS says that increasing the speed limits — allowing more people to drive faster — will mean more fatalities on the road.
