Cars.com did a survey of the fastest and slowest states in the nation in terms of speed limits. How fast do you think that North Dakotans drive? First let's look at how Cars.com came up with this list. It's simple - they looked at the speed limit in every state and also looked at the length of the roads (in miles) with the highest speed limits.

First? Texas. According to Cars.com-

"Texas' 85 mph speed limit as the highest in the U.S. Moreover, the state's average top speed for all three types of roadways is 78.3. That's nearly 2 mph greater than the next-fastest state, Idaho, which has a top limit of 80 mph and an average top speed of 76.7 mph."

The slowest state in the nation is Alaska and Hawaii at 55 and 58 MPH respectively.

Moreover, 22 additional states have a top speed limit of 70 mph, five of which (Michigan, Mississippi, North Carolina, Pennsylvania and Tennessee) average 70 mph across their urban and rural interstates and other limited-access roads, as listed by the Governors Highway Safety Association.
