Article 2 - Traveling Expenses
Section 599.626.1 - Transportation Expenses - Excluded Employees

(a) Transportation expenses consist of the charges for common carrier fares; rental car fees; private car mileage allowances; emergency repairs to state cars; overnight and day parking of state, rental or privately-owned cars; bridge and road tolls; necessary taxi, bus, or streetcar fares; and all other charges essential to the transport from and to the official headquarters while on authorized state business. For purposes of this section, common carrier includes an airplane, a bus, and/or a train.

(b) Reimbursement will be made only for the method of transportation which is in the best interest of the state, considering both direct expense as well as the officer's or employee's time and/or that support approved statewide initiatives. Provided the mode of transportation selected does not conflict with the needs of the agency, the officer or employee may use a more expensive form of transportation and be reimbursed at the amount required for the least expensive mode of travel that is in the best interest of the state. Both modes of transportation will be shown on the travel claim with reference to this section. A cost comparison shall be completed and attached to the claim. Cost comparisons shall include only the least costly methods of transport for those expenses actually being substituted and shall include only the expenses of traveling from one location to another. Transportation expense at the travel work location will be reimbursed based on the actual business transportation expenses incurred while at the travel location.

(c) Expenses arising from travel between residence or garage and headquarters shall not be allowed regardless of the employee's normal mode of transportation. When an employee is required to report to an alternate work location, the employee may be reimbursed for the number of miles driven in excess of their normal commute to work.

Exceptions to the above are:

(d) When an employee's regular work assignment requires the employee to report to or rotate among two or more posts or work stations at different geographic locations and the employee is instructed to report to a designated post, the reimbursable distance from the employee's residence to the designated post and return shall be limited to that which exceeds the round trip distance from the employee's residence to the employee's designated headquarters. Reimbursement shall be computed at the rate set forth under section 599.631 of these regulations.

(e) No reimbursement will be allowed for transportation expense when the employee uses a privately-owned motorcycle or motor-driven cycle in the conduct of state business.
