Method and means of deterring speeding are disclosed. A plurality of detection devices positioned along a road detect a transmission device mounted in a vehicle as it passes in proximity to the detection devices. Each transmission device is identifiable to a registered user via an identifier unique to the transmission device. When a vehicle carrying a transmission device passes a detection device, the unique identifier and the time of the vehicle's passing are stored. Known distances between the plurality of detection devices enable calculation of average speed of the vehicle using the time stamps of the vehicle's passing between any two detection devices. If the vehicle's average speed exceeds an acceptable speed for that portion of road, the registered user is notified, thereby deterring future speeding. A fine can be deducted from an account associated with the registered user or the registered user's transmission device.
