The statutory basis for this regulation is C.R.S. 42-3-135. The purpose of this regulation is to establish what information should be maintained for vehicles subject to fees under C.R.S. 42-3-134 (13) (b) (I),(II) & (III).

I. Calculation of Registration Fees Calculation of Registration fees for vehicles described within these rules will be based on the following criteria; gross vehicle weight, total miles traveled during the previous 12 month registration cycle or mileage reporting period and whether the vehicle operation is for private use or as a common contract carrier.

To qualify as a private carrier, more than 50% of the total miles traveled by a specific vehicle within the registration mileage cycle is for private use.

A. Private Use Requirements 1. Documentation to substantiate that the cargo for each mileage record was owned by the carrier, such as bills of sale and manufacturing documentation, etc..

2. In addition, mileage records as defined in these rules are required.

B. Mileage History Mileage history is defined as those miles operated by a vehicle during the continuous twelve- month period immediately preceding the registration of the vehicle, or, in the case of a vehicle registered under the International Registration Plan (“IRP”), regardless of base jurisdiction, the “preceding” year, as defined in the International Registration Plan.

1. Reguirements a. Mileage history is established for both interstate and intrastate vehicles from all the following information except where otherwise noted:

1. Date of trip (starting and ending).

2. Trip origin and destination.

3. Route of travel/beginning and ending odometer or hubodometer reading of the trip.

4. Total mileage.

5. Mileage by jurisdiction.

* 6. Unit number.

7. Vehicle identification.

* 8. Vehicle fleet number.

9. Registrant's name.

* 10. Jurisdiction of declared base in which apportioned registration was provided. * 11. Colorado percent paid for each registration year in question; if available, verified by each base jurisdiction.

12. Driver's name and/or signature.

13. A copy of the vehicle registration indicating taxes paid for the requested licensing year. * For IRP interstate vehicles only.

The above information shall be maintained for 3 years plus the current year. Computer summaries are not acceptable unless supported by the Individual Vehicle Mileage Records, as defined in the IRP.

C. Those vehicles which have no previous continuous twelve (12) months of mileage history shall be assessed the registration fees required for a vehicle traveling in excess of ten thousand miles per year. Such vehicles may, however, be the subject of a refund. Upon completion of the twelve- months mileage history, if it is determined the vehicle traveled ten thousand miles or less during the prior registration year, a refund of the difference between the registration fees paid for miles traveled over ten thousand and the registration fees for vehicles operated ten thousand miles or less may be requested.

D. Any owner who is replacing an existing vehicle may use the mileage history of the vehicle being replaced as qualification for the fees assessed on the new vehicle as defined by 42-3-134 (13)(b) (III). For the mileage history to qualify, the existing vehicle must have been registered and in operation for the previous twelve (12) months. The license plates from the existing vehicle must be transferred to the replacement vehicle for Colorado based vehicles.

E. When a person purchases an established business which includes vehicles, the mileage history of those vehicles may be used as qualification for the fees assessed as defined by 42-3-134 (13)(b) (III). For the mileage history to qualify, the business operations must remain the same, the vehicles must have been registered in Colorado and in operation for the previous twelve (12) months. Copies of the previous owners current registrations must be presented at the time of registration by the new owner in order to substantiate mileage information.

F. Any owner requesting a refund of registration fees paid for a specific vehicle or vehicles shall submit the records as required by the Department under sub-part 1.a above.

G. The Department, upon verification of the refund claim, shall refund the difference to the owner.
