Do not confuse "average" speed cameras with normal speed cameras.

The ones on the gantries measure your speed at that time, but as said, these are usually only switched on when variable limits are set. I believe that the M25 ones are now all digital and linked to an ANPR system and teh DVLA database. If caught, the system reads the plate, prints a letter to the registered keeper and an automated folding system puts it into an envelope, seals and posts it, without human intervention. People only get involved if the ANPR database flags it, or it cannot read it properly. In the case of one of these, it alerts the police force immediately, so that the car can be stopped if patrols are nearby/available.

Average speed cameras are the yellow ones in roadworks. They use ANPR technology to record you passing the first camera, then when it reads it again, it calculates your average speed between the cameras. Braking for these is futile, as well as dangerous.

Re: Hill Holder / M25 Speed Cameras

Lesson learnt, just follow the car in front of you.

Seen people motoring past gantries at 100+ before, most usually an Audi, BMW or some supercar! Risky game

I'm not sure about when there is no restriction in place.

When there is a restriction other than 70 (say 50 due to an accident or congestion) then they are definitely active. If your average speed through the cameras is greater than 50 you will get a ticket, I can confirm this (there is the rumour about 10% lenience but i'm not sure how true that is)

But when it is normal 70mph i'm not sure if they are active or not. But best to be safe and stick to 70

Re: Hill Holder / M25 Speed Cameras

Buy a snooper 3zero camera detector if you need to speed, detects lazer, radar and fixed cameras by satellite. It's kept me out of trouble

Better would be to stay alert, and look well ahead, and moderate the speed to the conditions. Mostly speed detection is done where situations are higher risk, or there is a history of speeding.

Lazer camera detectors will alert you if the lazer beam hits it, but the beam is quite precise so can be missed by the detector.

Radar cameras are mostly taking readings from behind you as you pass. The only radar to be detected will be that reflected to your detector from other objects. With no oncoming traffic, you may not get the warning.

Fixed camera data needs to be updated, but not such a problem as new cameras are rare.

Average speed cameras will not be seen by any detector, or be on any database, but your eyes should be enough, both for the cameras and the speedometer.

Actually you will find that average speed tests (specs) are on the database. I update the device around once a month.

Even my TomTom knows where the average speed cameras are (when I bother to update it that is).

Re: Hill Holder / M25 Speed Cameras

Usual ACPO guideline is 10% +2 mph, so you can theoretically get away with 79mph etc. However, the reason for the leniency is inaccurate speedos and it's very difficult to stay at exactly a speed as indicated by the speedo whilst paying attention to everything else.

Many areas actually work on 10% + 5mph, as they'd catch many people at the ACPO rate.

Can't say for the M25, but all other mandatory limits on motorways (speed with a red ring around it) are enforced by effectively a digital version of a Gatso camera, ie you only get done at the location of the camera. Average speed camera are usually at road works sites, although there are a few at permanent reduced limits on other areas.

Contrary to popular belief, all the cameras are well signposted and there is no appetite to catch people speeding - to get the motorway to flow, you need people to do the displayed limit, so there's no benefit in getting 60 off an odd motorist if it results in congestion.

From end July this year, all the 60 fines went up to 100. Points stay at 3 per offence.
