Could Minnesota Change Its 85% Rule With Speed Limits?

There's talk about changing speed limits across the country. Some states, like nearby North Dakota, have increased their speed limits because of modern technology and safety features. In North Dakota, motorists can now enjoy an 80-mile-per-hour speed limit on multi-lane highways.

The 85% Rule Was Developed In the 1930s

The Associated Press tells us about the mysterious 85% rule that many of us have never heard of. It was used to set speed limits back in the 1930s and 1940s across the country. The thought behind it was that the speed limit should be set at what 85% of drivers naturally drive at. That means if 85 out of 100 vehicles drive at 55 mph on a stretch of highway, that's what the speed limit should be.

Things Have Changed Over The Years

Imagine driving in a 1930s roadster where you feel every bump along the road. They were noisy, uncomfortable, and loud! Modern vehicles have more safety features, handle better, and have a more comfortable ride.

Nine States Now Allow 80+ MPH Speed Limits

North Dakota just became the ninth state to have speed limits as high as 80 mph. South Dakota, Montana, Wyoming, Idaho, Nevada, and Utah all have highways with 80 mph limits. A stretch of highway in Texas even has an 85 mph speed limit.
