In California, drivers of qualifying clean alternative fuel vehicles such as plug-in hybrids and zero-emissions vehicles are eligible to apply for an HOV sticker through the California Department of Motor Vehicles. Under regulations, once you receive the sticker, you may use designated HOV lanes, even if you’re driving alone. Please contact your dealer or the California DMV for details, or visit https://www.dmv.ca.gov/portal/dmv/?1dmy&urile=wcm:path:/dmv_content_en/dmv/vr/decal.

Other states and localities have different requirements. Check with your state or local authorities for further requirements.
