Abstract

A method, system and computer program product for providing notification to the driver of a vehicle when the vehicle'"'"'s speed exceeds the speed limit within a speed control zone. A vehicular speed control (VSC) utility retrieves information indicating the speed limit of the speed control zone from an information signal detected by a radio receiver. The receiver is electrically coupled to the speed sensor circuitry of the vehicle to track the vehicle'"'"'s velocity. The VSC utility determines whether to activate a speed notification alarm by comparing the vehicle'"'"'s velocity with the zone'"'"'s speed limit. When the vehicle'"'"'s velocity exceeds the speed limit of the speed control zone, the VSC utility triggers the alarm and alerts the driver of the excessive speed with an audible/visible notification. The VSC utility may re-trigger the alarm if the driver continues to exceed the speed limit while driving within close proximity of the speed control zone.
