In Colorado driving records provided by the CO Division of Motor Vehicles reflect activity that has been retained for the last seven years.

Driving records are for seven years and cannot be limited to show any time period less than seven years. The CO DMV records are maintained in accordance with State and Federal law, which includes the Fair Credit Reporting Act and the requirements of the Federal Trade Commission.

So it would appear a conviction for a defective or unsafe vehicle violation will remain on your Colorado driving record for 7 years. For a copy of your record or to get more information on your driver's history contact the Colorado DMV.
