A government or rental vehicle may be authorized as a means of transportation to the travel destination and as a means of transportation while at the destination.
Whenever practical, a government vehicle shall be used for ground travel to and from travel destinations within one hundred (100) miles of the District of Columbia, as measured from the John A. Wilson Building.
If a government or rental vehicle is authorized as a mode of travel, the vehicle may be used at the destination only for the following purposes:
Except for collision damage waivers, personal accident insurance, or theft insurance for travel within the United States, the District shall reimburse authorized and reasonable expenses associated with the use of government and rental vehicles, including the costs of fuel, parking fees, and tolls.
An employee shall rent, and the agency shall only reimburse the expenses of, the least expensive compact car available, unless a waiver for another class of vehicle is approved by the employee's agency. In general, a waiver should only be approved when:
An employee shall refuel a rental vehicle before returning the rental vehicle to the drop-off location. An employee shall not be reimbursed for purchasing a pre-paid refueling option for a rental car or for rental car vendor refueling charges; except, that if it is not practical to refuel completely prior to returning the rental vehicle because of safety issues or the location of the closest fueling station, the employee may be reimbursed for rental car vendor refueling charges.
An employee shall be responsible for any additional cost resulting from unauthorized use of a government or rental vehicle and may be subject to administrative and criminal liability for misuse of government property.
