Fleet managers work for companies that have a fleet (or fleets) of vehicles. Most of these companies are businesses that deliver packages to customers or ship items in bulk to certain companies. Some of the responsibilities of fleet managers include supervising current employees, hiring new employees, inspecting vehicles for repair, developing safety rules that correspond with OSHA, directing fleet operations, calculating the arrival time of a load based on the departure and distance, ensuring compliance with the Department of Transportation (DOT), and more. Fleet managers generally work out of an office, but they also inspect vehicles outdoors and in the shop. They are always working with the drivers they manage, as well as people who work in the repair shop in order to ensure repairs are done on schedule. Fleet managers also work with and submit reports to the transportation director, vice president and other managerial directors of their respective companies. Most employers require their fleet managers to hold an associate's or bachelor’s degree, but some employers may require a master's degree. Many employers also prefer to fleet managers who have at least a few years of relevant experience for the job. Most of the time, fleet managers will work a full 40-hour work week, but it is not unheard of for them to work overtime as needed by the demands of their companies.
