**High Occupancy Vehicle (HOV) lanes** are designed to facilitate the transit of vehicles carrying multiple people, thereby reducing congestion and promoting carpooling. For a vehicle to be considered high occupancy, it must meet certain requirements, such as transporting only people and not exceeding a weight of 3,500 kilograms.

However, there are exceptions to these rules. **Vehicles for people with disabilities** can use the HOV lane even if only the driver is traveling, as long as the vehicle has the **disabled badge**. This means that even if a car is occupied only by the driver, it can use the HOV lane if it carries this badge, which facilitates the mobility of people with disabilities.


Therefore, a car with the disabled badge can travel in an HOV lane, even if it is only occupied by the driver.
