Many businesses purchase or lease fleet vehicles to deliver goods to customers, as well as providing vehicles for sales representatives to travel to clients. In some jurisdictions and countries, fleet vehicles can also be privately owned by employees. These vehicles are often called the "grey fleet"[1] and are used for work purposes. Fleet vehicles can be managed by a fleet manager or transport manager using fleet management software. Vehicles may be connected to a fleet telematics system by way of a Fleet Management System, also known as an FMS.
