Speed Cameras

Speed Cameras around the UK have been found to have varying tolerances , at the start of 2019 it was alleged that some cameras were calibrated to the extent that even one mile over the 70 limit would generate a ticket. From a freedom of information request it was found that most forces use 10% plus 2 miles , so allowing a good error margin for both drivers and speedometers, however the Metropolitan Police are more generous with 10% + 3 miles, citing volume of traffic means a greater tolerance is required. Whilst some forces refused to provide any information for fear of encouraging speeding .
