Road speed limits are used in most countries to regulate the speed of road vehicles. Speed limits may define maximum, minimum or variable speed limits or no speed limit and are normally indicated using a Traffic sign. Speed limits are commonly set and enforced by the legislative bodies of nations or provincial governments.
The term speed trap can refer to a point where a speed limit is strictly enforced by police.

It may also refer to locations where a speed camera is posted. Alternately, the term may also refer to a speed limit that is enforced by timing how long a vehicle takes to traverse a measured distance. Cities or road sections become known as speed traps where police have a reputation for writing an unusually high number of traffic tickets, especially speeding tickets.

Sometimes the posted speed limits are not easily seen; in other places, the limits are set such that many vehicles are caught. In many of these uses, the term speed trap connotes speed limit enforcement for purposes of ticket revenue or traffic deterrence instead of safety. Such speed traps may be referred to as revenue traps.

foto radars 101The use of road rule enforcement cameras is contentious. Police and government were accused of ‘Big Brother tactics’ in over-monitoring of public roads, and of ‘revenue raising’ in applying cameras in deceptive ways to increase government revenue rather than improve road safety.

Various legal issues arise from such cameras and the laws involved in how cameras can be placed and what evidence is necessary to prosecute a driver varies considerably in different legal systems

World Moment !  The BBC television programme Top Gear tested this theory, with inconclusive results. Mythbusters concluded while driving a turbine vehicle that it was actually fast enough for the speed camera to not even take a photograph. This theory is also commonly extended to radar and lidar devices, but its effectiveness is questionable.
