The High Occupancy Vehicle Lane Exemption Reauthorization Act aims to prolong the period during which certain alternative fuel and clean vehicles are permitted to use High Occupancy Vehicle (HOV) facilities. This legislation specifically amends section 166(b)(5)(A) of title 23, United States Code, to update the authorization's timeframe. The bill changes the current expiration date from September 30, 2025 , to September 30, 2031 . This reauthorization effectively extends the exemption for an additional six years, allowing qualifying clean vehicles to continue accessing HOV lanes and supporting the adoption of more environmentally friendly transportation methods.
