1 Colo. Code Regs. § 103-1-4.28
All state-owned vehicles will be serviced on a regular basis, at frequencies and intervals appropriate for the vehicle assignment as determined by SFM. Every effort must be made by the driver and vehicle coordinator to service the vehicle at or near the established service interval. Repairs required because of failure to follow the scheduled preventative maintenance may be the responsibility of the agency to which the vehicle is assigned. SFM will authorize those services deemed necessary based on vehicle service records. Vehicles more than 50% beyond the established schedule shall be deemed as "overdue" and will be reported to the agency vehicle coordinator for resolution. Continued overdue services may be reported to the agency leadership for resolution.
