Many speedsters were already driving 70 miles per hour on interstates in Ohio, but now they can do so legally.
The Ohio Department of Transportation says the speed limit is increasing on more than 570 miles of interstate highway.
The Ohio State Highway Patrol is now enforcing the five mile per hour hike along some sections of interstate in Ohio.
The increase applies to parts of interstates 70, 71, 75, 76, 77, and 90. It doesn't cover sections of those roads in major metropolitan areas and a few smaller cities along the way.
That means the speed limit will remain 65 around the Lima area. New and updated signs will alert drivers as to where the speed limit is higher.
Troopers say many drivers were already going 70 to 75 miles per hour on I 75 and they're warning that with the increase, drivers might not get away with going five to ten miles over the speed limit anymore.
Troopers are also concerned about the speed limit increasing so close to the Fourth of July holiday when more people will be out on the roadways.
They suggest allowing extra distance between vehicles to make up for the speed difference.
Ohio is the 34th state to allow drivers to travel at least 70 miles per hour in some areas.
U.S. routes and state routes could soon see the increase as well. An amendment to the state budget bill allows 70 mile per hour driving along some freeways.
