Road speed limit enforcement in the United Kingdom is the action taken by appropriately empowered authorities to attempt to persuade road RAC Road Atlas Britain PDF users to comply with the speed limits in force on the UK’s roads. Opposition politicians and some road safety campaigners claimed that lives were being put at risk. Enforcement is used to increase compliance with speed limits.
With 3.2 miles to 1 inch scale A3 format, this spiral bound road atlas features easy to use road mapping. It indicates safety camera locations and contains 64 town and city centre street plans. It also includes: motorway services listed with facilities information, motorway junction access information, and park and ride locations.
One of the main motivations for enforcement is to reduce road casualties, particularly at accident blackspots. In 2002 the Select Committee on Transport stated that „Most drivers and pedestrians think speeds are generally too high but 95 per cent of all drivers admit to exceeding them“. Groups most likely to speed excessively are those driving in a work related capacity, members of high income households and young males. Motorcyclists also frequently speed as do HGV drivers commonly on single carriageway main roads where their speed limit is 50 mph.
There are many methods used by authorities, in places where the speed limits are not generally observed, to attempt to achieve greater compliance. There are several types of speed camera in use. Speed cameras must be calibrated and certified before the images from it are acceptable to the court, including the cameras used in police vehicles. These cameras are installed beside a road and record the instantaneous speed of vehicles and a photograph of vehicles that have been identified as breaking the speed limit. D-cam digital cameras which use infrared to take a picture of a vehicle as it approaches, which includes an image of the driver.
These cameras then transmit the image and speed to the authorities virtually instantly. Police officers can use LIDAR speed guns or sometimes the older and less accurate radar speed guns to gather evidence for prosecution. These may be operated from temporary static sites or from within police vehicles. Known as the SPECS system, these cameras measure average speeds over a known or measured distance. The first average speed camera in Scotland was installed on the A77 road in 2004. Vehicle activated signs that illuminate to indicate to a driver that they are exceeding the speed limit — these do not result in the issuance of a penalty, merely serve as a warning.
Community Speed Watch is a partnership between local people, the Police, the Fire Service and local councils. Volunteers spend a short time each week monitoring speeds and noting number plates. Those identified as speeding are sent a warning letter and the police will take further action if the same vehicle is identified as speeding three times. Some classes of vehicles are required to have speed limiters which enforce a maximum speed by physical means. New vehicles should be fitted with limiters as follows.
