Some Police Forces Have Revealed Speed Camera Tolerances

We've all experienced the dread of driving down a road and then looking in our rear view mirror only to see a big yellow box behind us. Our eyes immediately go to the speedometer.

But what if you're slightly over the limit? How accurate is a speed camera? Is it even turned on? Is there any leeway?

Most police forces have a tolerance of 10 percent plus 2 miles per hour (mph) above the limit before a speed camera 'flashes'. So on a 30 mph road, a camera wouldn't normally activate unless a car drove past at 35 mph or faster.

On a 70 mph stretch of motorway, the threshold would go up to 79 mph.

This 'buffer zone' exists in order to improve driver safety. It means that drivers don't have their eyes fixed on their speedometer instead of the road.

Auto Express contacted 45 UK police forces. Of the 33 that responded, 25 shared information about when their speed cameras activate if a driver is going above the speed limit.

So what happens if you do get caught speeding? Well, if the offence is minor, you might be asked to go on a speed awareness course rather than take the fine and points.

For more serious offences, though, that option isn't on the table and you face a fine, points on your licence and a possible ban.
