Speed Limits by State

Since 1995, each state has been able to set their own laws for controlling speed limits, and in the time that’s elapsed since then, every state has raised their maximum posted speed limits on interstates in rural areas. On rural interstates, the maximum posted speed limit across all fifty states ranges between 60mph in Hawaii to 85mph in certain areas of Texas. 

In many states, however, the maximum posted speed limit for urban interstates (or highways) is often 55mph, while in certain states, such as Wyoming, it is as high as 75mph—80mph on certain sections of roadway. 

Out of all fifty states, thirty-five of them have a rural maximum speed limit between 70mph—75mph. Twelve states have rural maximum speed limits that are set between 60mph—65mph. Montana, Nevada, and South Dakota all have rural maximum speed limits set at 80mph.

It goes without saying that every state in the U.S. has a set maximum speed for their roadways that drivers cannot legally go above. However, between the years of 1995—1999, there was no set speed limit in the state of Montana after the federal speed limit was lifted. In 1999, a judge ruled that there must be a speed limit, citing that it was probably safer that way.
