Source: FleetAnswers What is the role of the fleet manager? Traditionally, it has been to manage the fleet vehicles of a company, whether those vehicles are cars, trucks, vans, planes or boats, although land vehicles are by far the most common. However, in recent years, that role has changed. Instead of simply managing the fleet and its drivers, the modern fleet manager is one who handles all travel arrangements. This, then, is creating a new title of "Mobility Manager" or "Fleet and Travel Manager."
