1 Colo. Code Regs. § 103-1-2.20
A state employee who operates a State Fleet pool vehicle assumes full responsibility for the vehicle until its return to the State Fleet pool. The operator assumes all the responsibilities outlined in section 4.20 through 4.43 . This includes personal possession of a valid U.S. driver's license, proper care of the vehicle, storage charges, and personal responsibility for parking traffic violations, tolls and any taxable commuting. State employees issued a vehicle are responsible for exercising reasonable diligence in the care of the vehicle at all times. Failure to take proper care of a State Fleet pool vehicle may be justification to refuse further vehicle issuance and may result in the agency being billed directly for services.
