A system for monitoring certain vehicle operating information and recording other data includes a vehicle interface unit (22) permanently mounted to a vehicle, and a data recorder unit (20) removably interconnectable with the vehicle interface unit (22). The vehicle interface unit (22) receives signals from the vehicle through the vehicle's interface connector (24), such as signals pertaining to distance traveled and other operating characteristics, e.g. operation of headlights, directional signals, brakes, or seat belts, and such signals are communicated through a communications link to the data recorder unit (20). The data recorder unit (20) includes a memory (250) in which such information is stored, and the data recorder unit (20) can be disconnected from the vehicle interface unit (22) and interconnected with an external device such as a computer (100) or printer (102) for outputting information stored in the memory (250). The data recorder unit (20) can also be used to store other information, such as pertaining to business expenses or the like. The data recorder unit (20) allows an operator to designate whether the miles traveled by the vehicle are for business or personal use, thus enabling the operator to keep close track of business or personal use of the vehicle and other expenses incurred by the operator. Information stored in the data recorder unit (20) can either be printed out on a printer (102) or download into a computer (100) for generating printed report.
