Renewals Remove the mailing label found on the renewal postcard.
Place the emission sticker on the postcard where you removed the mailing label. Return the postcard with your payment in the envelope so that it will reach the County Clerk s office before the last day of the expiration month. If you have recently purchased a vehicle for cash from either a private party or a dealer, licensing requires all original title documents to be submitted along with a new Air Care Colorado emission test dated within 120 days of purchase date. The dealership must supply you with proper titling documents within 45 days either by mail or customer pick up. The private party should give you proper title, odometer, and emissions at the time of sale.
