Abstract: A motor vehicle speed monitoring system is disclosed as a device to acquire and record the top speed obtained by a motor vehicle during each operating session. Such monitoring allows for the security that one's children, employees, valets, mechanics, or others entrusted with the care of a vehicle have not operated it above acceptable speed limits. The system digitally records the top speed of the vehicle every time it is started and keeps a log of the speed and the time and dates at which it occurred. The owner or authorized user may review the internal log by entering a password key into a keypad.
