Random information on the term “SPECS”:

SPECS is an average speed measuring speed camera system originally manufactured by Speed Check Services Limited, from which it takes its name. It is one of the systems used for speed limit enforcement in the United Kingdom. Speed Check Services was acquired by Vysionics in 2010.

SPECS cameras were introduced in 1999.

SPECS cameras operate as sets of two or more cameras installed along a fixed route that can be from 200 metres (660 feet) to 10 kilometres (6.2 mi) in length. They work by using an automatic number plate recognition (ANPR) system to record a vehicle’s front number plate at each fixed camera site. As the distance is known between these sites, the average speed can be calculated by dividing this by the time taken to travel between two points. The cameras use infrared photography, allowing them to operate both day and night.

There is a popular misconception that the Home Office has approved the SPECS system for single-lane use only. According to this theory, a motorist can therefore switch lanes between cameras and claim non-approval to avoid prosecution for speeding. Indeed, the cameras can only operate in pairs, where each pair only monitors one lane of a multi lane road. So in theory, one can escape detection by changing lanes between the entry and exit cameras. In reality, two or more sets of pairs of cameras are arranged to have overlapping areas of monitoring; since the driver cannot tell which cameras are ‘entry’ and which are ‘exit’, as they look identical, they cannot tell where to change lane to escape detection.
