Speed limit enforcement is the action taken by appropriately empowered authorities to check that road vehicles are complying with the speed limit in force on roads and highways. Methods used include roadside speed traps set up and operated by the police and automated roadside 'speed camera' systems which may incorporate the use of an automatic number plate recognition system. Traditionally the police would have used stopwatches to measure the time taken for a vehicle to cover a known distance, but more recently they have had speed guns and automated in-vehicle systems at their disposal.
