Some Interstate Highways in Montana to Increase to 80 MPH

HELENA, Mont. (AP) — Speed limits on some interstate highways in Montana will increase to 80 mph this fall, but the cost of a speeding ticket will go up, too.

Gov. Steve Bullock signed Senate Bill 375 on Monday. It calls for increasing speed limits on some interstate segments from 75 mph to 80 mph in areas where the Department of Transportation deems it safe.

Fines for exceeding the speed limit will also be raised from a maximum of $100 to $200. The fines are expected to bring in an additional $95,000 in revenue every year.

The law will take effect Oct. 1, after the summer driving season.

Three other proposals to raise highway speed limits died this session after the Montana Highway Patrol spoke against those bills. The patrol favored SB375 — the only proposal to include increased fines.
