Vehicles containing more people than just the driver are a relative rarity on our highways. Some estimates place them at less than 10% of the total number of vehicles on the highway! In order to encourage the efficient movement of more people, High Occupancy Vehicle (HOV) lanes were created. There is an added benefit, filling up the vehicle means a "greener" journey as well.
In order to use an HOV lane, you must qualify as a high occupancy vehicle, which in BC is defined as a bus or any other type of vehicle under 5,500 kg GVW carrying the required number of persons as indicated by the sign controlling the HOV lane. If you and your vehicle fit the definition, you may find yourself travelling at speed in the HOV lane while others that do not qualify must crawl along in the other lanes.
