The national speed limit was changed to 65 miles per hour in 1974 as part of the Emergency Highway Energy Conservation Act, which aimed to reduce fuel consumption during the oil crisis. This speed limit was in effect until it was repealed in 1995, allowing states to set their own limits. Some states had already raised their limits before the repeal, leading to a variety of speed limits across the country.
