Montana has banned the use of cameras and other devices used to enforce traffic laws.
Both Houses of the Montana legislature passed the measure by large margins and Gov. Brian Schweitzer signed the bill Tuesday.
“An automated enforcement system designed to detect traffic violations that is attached to a traffic control device may not be used to enforce traffic laws,” Montana code now says.
An earlier version of the bill had allowed exceptions for enforcement programs already in motion—namely in the cities of Bozeman and Billings, which had made agreements with Redflex Traffic Systems—but lawmakers stripped that grandfather clause out, effectively ending those programs.
There remains an exception for enforcement cameras at railway crossings.
According to the AP, photo-enforcement programs are active in 25 states.
