A system, a method and device for controlling speed of a moving vehicle,
using portable and repositionable global positioning devices, speed limit
processors, and a database of legal vehicle speed limits is in
communication with the speed limit processor. Computer instructions
instruct the speed limit processor to match the current location of the
moving vehicle with a legal vehicle speed limit for a defined location
using the database. The speed limit processor communicates the legal
vehicle speed limit to the vehicle processor to control the speed of the
moving vehicle.
