Colorado Introduces Alternative Bill to Extend Emissions Inspection Waiver

Legislation (S.B. 257) to extend the new car emissions inspection exemption from 4 to 7 model years has been introduced in the Colorado Senate.  Under the bill, the state is also directed to adopt rules that allow for the use of on-board diagnostic testing equipment.  An attempt to extend the exemption to vehicles that have not yet reached their 10th model year was not approved in committee earlier this year. 

We Urge You to Contact Colorado Senate Transportation Committee Members (Contact Information Below) Immediately to Request Support for S.B. 257

  • S.B. 257 acknowledges the relatively minimal environmental impact of the vehicles targeted for this exemption.
  • S.B. 257 acknowledges that it is senseless to test newer vehicles, the results of which demonstrate no significant air quality benefits.   The idea behind exempting any class of vehicles is to reduce costs while not losing appreciable emission reductions.  This strategy builds support for emission inspection programs, but also directs finite resources to where they will be most valuable in cleaning the air.  
  • Colorado already exempts pre-1976 collector cars, kits and street rods from emissions testing.  The logic for this trend is clear; such vehicles do not contribute in significant ways to air quality problems.  This logic applies equally to newer cars.     

DON’T DELAY!  Please contact members of the Colorado Senate Transportation Committee immediately to request their support for S.B. 257.
