A highway speed information system for use with a vehicle includes an in-vehicle speed information device selectively installed in a vehicle equipped with a cruise control module. The information device includes a processor, memory, and an output device. A global position system (GPS) is in data communication with the processor and configured to determine a geographic location of the vehicle. The memory is configured to store programming and a speed zone database indicative of a plurality of speed zones defined by GPS coordinates. Programming determines a current geographic location of the vehicle and associated speed limit, as well as a new current geographic location after a predetermined time-each location being associated with a speed limit. If the cruise control module is activated, it is automatically set to the speed limit associated with the current geographic location. |
