Except as specifically authorized by statute, an authorization in a statute or regulation to transport the effects of an employee or other individual at Government expense is not an authorization to transport an automobile.

Under regulations prescribed under section 5738 of this title, the privately owned motor vehicle of an employee, including a new appointee and a student trainee to the extent authorized by sections 5722 and 5723 of this title, may be transported at Government expense to, from, and between the continental United States and a post of duty outside the continental United States, or between posts of duty outside the continental United States, when—

(1) the employee is assigned to the post of duty for other than temporary duty; and

(2) the head of the agency concerned determines that it is in the interest of the Government for the employee to have the use of a motor vehicle at the post of duty.

Under regulations prescribed under section 5738 of this title, the privately owned motor vehicle or vehicles of an employee, including a new appointee or a student trainee for whom travel and transportation expenses are authorized under section 5723 of this title, may be transported at Government expense to a new official station of the employee when the agency determines that such transport is advantageous and cost-effective to the Government.

An employee may transport only one motor vehicle under subsection (b) of this section during a 4-year period, except when the head of the agency concerned determines that replacement of the motor vehicle during the period is necessary for reasons beyond the control of the employee and is in the interest of the Government, and authorizes in advance the transportation under subsection (b) of this section of one additional privately owned motor vehicle as a replacement. When an employee has remained in continuous service outside the continental United States during the 4-year period after the date of transportation under subsection (b) of this section of his motor vehicle, the head of the agency concerned may authorize transportation under subsection (b) of this section of a replacement for that motor vehicle.

When the head of an agency authorizes transportation under subsection (b) or (c) of this section of a privately owned motor vehicle, the transportation may be by—

(1) commercial means, if available at reasonable rates and under reasonable conditions; or

(2) Government means on a space-available basis.
