DENVER (CBS4)– Most newer vehicles in Colorado will no longer have to submit to any type of emissions testing for at least seven years.
The change takes effect in 2015.
The Air Quality Control Commission approved the change on Thursday.
The previous exemption was four years for new vehicles.
The sever year exemption becomes the longest of any emissions program in the U.S.
The period was extended after a state audit showed 93 percent of vehicles on the road passed the emissions test.
