Auto Express has recently released the findings of a recent study that they conducted into the speeds you must travel at in order to trigger a speed camera. The results are interesting and vary from county to county.
Auto Express sent a freedom of information requests to the UK’s 45 police forces to ask just how fast you must be travelling to be hit with a ticket from the cameras.
They claim that the majority of forces that responded advised that a camera would only activate when vehicles exceeded the speed limit by 10% + 2mph – 35mph on a 30mph road and 79mph on a motorway – which is in line with the Association of Chief of Police guidelines.
While this information may seem like a green light to get where you’re going more quickly, the report also reveals that not all forces use the scale and some forces declined to reveal the threshold at all.
So what are the thresholds?
Below is a list of some of the information that was gathered during the study!

Can you trust your bike’s speedometer?
For the most part, yes. The modern bikes should always over-read the speed that you are travelling. For example, when travelling at an indicated 70mph on your bike, a GPS device would usually clock you at around 67mph.
Manufacturers are bound by legislation that means a vehicle’s speedo cannot underestimate the vehicles speed, most over-read by a few percents. Old vehicles may have much less accurate speedometers. It could be due to wear and tear, less accurate manufacturing methods or poor maintenance, all of which could add up to a speedo that wanders between speeds giving a very inaccurate reading.
