How many people are required for the HOV lane at minimum?

[CharlotteRose]

The HOV (High-Occupancy Vehicle) lane requires vehicles entering this lane to have at least 2 or more occupants (including the driver). Single-occupant vehicles are prohibited. The HOV lane is also known as the carpool lane. When this sign appears, it defaults to allowing only vehicles with 2 or more occupants. The HOV lane is marked with HOV-2+, or a combination of 2+ and a car image. Special cases may have unique markings, such as in Wuxi and other regions where HOV lanes require 3 or more occupants, marked as HOV-3+, or with 3+ added next to the car on the sign. The significance of the HOV lane: The dedicated HOV lane originates from Europe and America, playing a positive role in optimizing travel structures and road resource allocation, reducing the occupation of road resources by empty vehicles, and promoting carpooling and green travel. Carpooling reflects the encouragement of the sharing economy, providing a new solution to improve the efficiency of human-vehicle-road coordination, promote dynamic balance in transportation supply and demand, and optimize travel methods.
