Abstract
In accordance with the present invention, a position of a vehicle is detected by a receiver at the vehicle from a global positioning system. A speed limit associated with the position is determined from a centralized database accessible via a wireless network. An actual speed of the vehicle at the detected position is compared with the determined speed limit for the detected position, such that if it is determined that the actual speed exceeds the determined speed limit at the detected position, the driver may be alerted.
