This exemption does not include access to High-Occupancy Vehicle lanes, except as provided in subsection (b) of this section.

(b) A fleet vehicle which has been certified by the Environmental Protection Agency as an ILEV, is operated by a covered fleet, and continues to be in compliance with applicable ILEV emission standards shall be exempt from High-Occupancy Vehicle lane restrictions.

(c) The Mayor may issue any regulations the Mayor considers necessary for implementing the exemptions provided for in this section within 45 days after March 14, 1995. The exemptions shall be available to covered fleet vehicles upon the adoption of such regulations.
