Motor Vehicle Fatal Crashes by Posted Speed Limit
In 1974, Congress enacted a national maximum speed limit of 55 miles per hour (mph). Amendments in 1987 and 1991 allowed states to increase speed limits to 65 mph on rural Interstates and similar highways.
The National Maximum Speed Limit was repealed in late 1995; speed limits are again set by the states, some of which have raised their maximum speed limits to 70 mph or above.
KEY: mph = miles per hour; R = revised.
a The "No Statutory Limit" speed limit designation is included in this category.
b The "blank" designation is included in this category. The 2010 - 12 figure includes fatal crashes where the speed limit was not reported.
