Abstract: The present invention is a system for monitoring and recording for later use values pertaining to the parameters of a subject motor vehicle. The monitoring and recording system includes a plurality of sensors capable of automatically measuring vehicle parameters and a system clock, both of which are in communication with a system computer. The system computer is capable of displaying and/or recording the data that is obtained (either automatically or manually) on a monitor or computer-readable medium for later use, respectively. The system can be used, for example, to monitor driving styles or to verify or detect infractions committed by the operator of the subject motor vehicle. In some embodiments, the monitoring and recording system is installed in the subject motor vehicle.
