Colorado Legislature passes changes in emissions testing

| Tuesday, April 15, 2003

A bill in Colorado eases the emissions testing schedule for heavy-duty trucks.

HB1053 has been passed by both houses of the state's Legislature and was sent to Gov. Bill Owens for his signature.

The bill exempts heavy-duty trucks – which it defines as those with a gross vehicle weight rating of 14,000 pounds or greater – from opacity testing if they are less than four years old. It also allows automated testing if the truck is less than 10 years old. In addition, if the vehicle is less than 10 years old, the bill requires testing every 24 months; older vehicles face yearly testing.

New vehicles are automatically issued an emissions-compliance certificate. However, used trucks cannot be sold or transferred unless the testing has been done.

HB1053 also removes some criminal penalties from the emissions-testing law.
