Can a Prius use the hov lane with one person in car?

Yes, a Toyota Prius can use the HOV (High-Occupancy Vehicle) lane with only one person in the car in certain states, as many jurisdictions allow hybrid vehicles to access HOV lanes regardless of the number of occupants. However, specific rules can vary by location, so it's essential to check the regulations for the state or region you are in. Some areas may require a special sticker or permit to qualify for HOV lane access. Always verify local laws to ensure compliance.
