High Occupancy Vehicle (HOV) Lane Exemption
Contingent upon approval from the federal government, qualified low-emission and energy-efficient vehicles are permitted to use HOV lanes, regardless of the number of passengers. Qualified vehicles must meet specified fuel economy requirements and are required to display the low-emission and energy-efficient vehicle license plate. However, use of HOV lanes may be restricted if certain traffic volume and speed criteria are not met. A low-emission and energy-efficient vehicle is defined as a vehicle that has been certified by the U.S. Environmental Protection Agency in accordance with U.S. Code Section 166, or that is part of a federally approved pilot program. (Reference Senate Bill 1320, 2009, and Arizona Revised Statutes 28-337 and 28-2416)
