High-Occupancy Vehicle (HOV) lanes, also known as carpool lanes, are dedicated highway lanes reserved for vehicles carrying a specified minimum number of occupants. These lanes are designed to encourage carpooling and reduce traffic congestion and air pollution. While many states across the U.S. utilize HOV lanes, specific regulations regarding exemptions for certain vehicle types can vary significantly.
Based on current regulations, several states have established HOV lanes with specific provisions for alternative fuel vehicles and other designated categories.
States with HOV Lane Regulations
The states that explicitly outline regulations and exemptions for their HOV (and sometimes High-Occupancy Toll or HOT) lanes include:
- California
- Colorado
- Florida
- Georgia
These states have implemented rules that allow certain low-emission or energy-efficient vehicles to use HOV or HOT lanes, often even if they do not meet the minimum occupancy requirements. This policy aims to promote the adoption of environmentally friendly transportation.
Specific Exemptions and Vehicle Types
Regulations for HOV and HOT lane exemptions differ by state, encompassing various types of alternative fuel and low-emission vehicles. Below is a summary of the exemption types and eligible vehicles for the aforementioned states:
| State | Exemption Type | Eligible Vehicles |
|---|---|---|
| California | HOV and HOT Exemption | Fuel Cell Electric Vehicles (FCEV), Natural Gas Vehicles (NGV), Plug-in Electric Vehicles (PEV) |
| Colorado | HOV Exemption | Hybrid Electric Vehicles (HEV) |
| Florida | HOV Exemption | Hybrid Electric Vehicles (HEV), Inherently Low Emission Vehicles (ILEV) |
| Georgia | HOV and HOT Exemption | HOV: Alternative Fuel Vehicles (AFV), HEV, PEV HOT: AFV, PEV |
