If a covered employee is required to live away from home in the course of receiving vocational rehabilitation services, the employer or its insurer shall pay to the covered employee money that: is sufficient to maintain the covered employee while the covered employee receives vocational rehabilitation services; but does not exceed $40 a week. The employer or insurer shall make payments for maintenance under paragraph (1) of this subsection in addition to the payment of compensation under subsection (b) of this section. Except as provided in paragraph (2) of this subsection, a covered employee who resides at home during vocational rehabilitation training is not entitled to reimbursement of transportation costs to and from the place of vocational training. In unusual cases the Commission may allow reasonable transportation costs. For the purposes of this section, vocational rehabilitation training may not last for more than 24 months.
