The Hawaiʻi Department of Transportation (HDOT) announced that Hawaiʻi Administrative Rule (HAR) 19-108-7 has been amended to allow Electric Vehicles (EVs) with EV license plates affixed to use High Occupancy Vehicle (HOV) lanes regardless of the number of people in the vehicle.

The exemption for EV use of HOV lanes authorized by Act 168 (2012) sunset on June 30, 2020. HDOT continued to support EV use of HOV lanes and took steps to ensure EV drivers were not cited under 291C-223.

EV use of HOV lanes is supported because of the reduction in transportation related pollution and reduction in fossil fuel dependency. In general, HOV lanes are designated to remove vehicles from normal lanes by incentivizing carpooling or use of public transportation. A list of HOV lanes on state highways can be found at https://hidot.hawaii.gov/highways/special-use-lanes/.
