(a) When the new official station is less than 250 miles from the old official station, the required mode of transportation is POV, unless there are reasons for not using a POV that are acceptable to the you (e.g., traveler is physically impaired, does not own or lease a POV, has only one POV which is used for family transportation, or the POV is not roadworthy for such a trip). Reimbursement for POV mileage is at the rate prescribed in § 302-4.300 of this subchapter.

(b) When the new official station is 250 miles or more from the old official station, the preferred mode of transportation is common carrier. However, you may authorize the use of POV for a househunting trip longer than 250 miles, provided you complete a written cost comparison in accordance with § 302-5.14(b).
