Average Speed Cameras

How do they work ???

I understand they measure your average speed between each camera - and if you are speeding they will flash you.

But if you are speeding for let’s say 40 miles - on the same stretch of motorway will they get you just the once or numerous times.

You don’t just speed for a couple of miles then slow down do you. - So how do they work?

And you never hear of people getting 3-5 tickets in one day

 

I think how it works is the first camera photographs your reg then the second camera also photographs you and they know the distance between the cameras. They time you and calculate if you have exceeded the speed limit.

TBH I would think you will get a ticket for every time you pass a camera over the speed limit.

Best to stick to the speed limit.

 

half of the cameras dont actually work, someone at work deals with the police and he was doing way over the limit, he contacted them and he said they dont work on that stretch 60% of them in the country dont work.

They dont work from 1 to another they work over 3-5 cameras and average your speed via that.

they are basically a waste of time and money. but are potentially saving peoples lives

 

they shoot you with a red lazer when you've triggered it, then they look back and check what speed you wo doing

 

There are 2 cameras switched on, its completely random which ones. When you pass through these two cameras, it calculates how long it has taken you to travel between them, and from this, calculates your average speed.

Slowing down for each camera does nothing, other than lower your average slightly I suppose. But driving through at 70mph then slowing for the cameras is pointless, you'll get caught.

The myth that switching lanes fools the cameras, is exactly that, a myth. This is the 21st century, if you honestly believe that changing lanes on a motorway stops a camera from reading your number plate then you deserve to get caught.

Contray to popular belief, these cameras aren't there to make money off of us, but to protect both yourselves passing through road works, and motorway workers.

 

It's not always a case of cameras not working. Some cameras are in operation at certain times of the day. (this is confusing as you're never sure if the cameras are on or off>)
A friend of mine late for work sped past a speed camera and was flashed. Got to work realised he's forgotten some important papers. Sped back home was flashed and also flashed on his way to work a second time. He got three penalty notices - total of 9 points in the space of an hour.

 

What about those that are not on roadworks eg those on the A1 near Lincoln. They are there to make money pure and simple. It's more dangerous having to jam the anchors on as you approach these and to keep taking your eye off the road to check you're keeping below 50 mph. I've seen a few close calls on that stretch due to the cameras.

 

By that logic how does anyone keep to any speed limit?

 

When there are no speed cameras, people have a glance now and again, not every 100 yards. They'll do you for doing 55 in that stretch so you have to keep checking every couple of seconds.

 

Cameras are put in places where there's been a certain number of accidents over a certain period of time. I don't know the area but they probably tried reducing the speed limit to start with and lets be honest, nobody ever takes notice of 50mph signs on a motorway unless there's cameras. I posed about an accident on the M621 yesterday, that's going to end up the same; a large stretch of it is currently 50mph speed limit, I reckon it's only a matter of time before they put cameras on it. There's 2 lanes of traffic, some people drive at the speed limit, 50mph, some do 60, some probably do 70. If someone driving at 50mph tries to overtake a lorry for example, checks their mirrors, and pulls out thinking it's safe to do so, is it their fault if a car doing 70mph in the outside lane hits them? A couple of times i've been the car doing 50mph and been ambushed by cars flying past at 70mph+.

I'd say the roads are safer with cameras on, as everyone 'should' be doing the same speed. I can comfortably stick to the speed limit, without constantly looking at my speedo, I don't understand how others can't.

 

I just put the cruise control on when I get to average speed camera areas, that way I'm not having to keep checking.

 

A mate of mine was done on Denby dale Road and went through all the cameras.

He ended up with one fine as it was one offence for spending and not a few offences.

Either way I work for the HA and it’s sort of true only so many cameras in one area are allowed on at one point. But they are always changed and the time of day makes no difference at all.

But knowing what there set at, I don’t get why people go faster than 50mph on a motorway. Seems like a pointless stupid risk. Just stick to the speed limit, I’ve worked on the motorway in roadwork’s before and a speed limit is there for a reason. Not for some idiot to get somewhere 3 mins quicker.

 

I don't understand people who get angry at speed cameras. You break the law and do the punishment, or stick to the speed limit, it's quite a simple choice really. Especially as it's something that is there to keep you/other people safe.

 

weird, i've done exactly that for the last 3 years and not got 1 ticket. granted i only max out at 60 but you have to, people still drive 10mph below the limit!

 

I got 3 points on M1 on June at Rotherham! 2.45 am doing 57 average!!!

 

Because some are there to make money and not for safety. I've been going on Hunningley Lane on my way to work for 30 years. I've never ever seen an accident in the dip near Vida playing fields. Speed van was regularly hiding behind the bus stop catching people doing just over 30mph both ways. It's downhill there and the only way to keep at 30 was to brake. My wife got done twice there doing 34 and 35, hardly dangerous when its a clear road and not a built up area. Since then they've increased the speed limit to 40 mph but people just drive at the speed they did before but now there's no need to break as you're coming down the hill.

 

Again SDM. It's becoming a habit. I've used that stretch dozens of times and never had to 'jam the anchors on' to slow down for it. I'm assuming you aren't paying attention when you drive or driving over the 70 limit prior to the limit being reduced to 50. It's 50 there for a reason. Traffic from Gamston, Eaton and Retford crossing the A1 have to cross to a central refuge to go North or go toward Mansfield. It's dodgy enough with the limit at 50 nvm 70. There's also a small airport at Gamston which isn't exactly Heathrow but is still a commercial venture and as such gets some amount of traffic from the A1, I assume some of this will be aviation fuel?

 

There's a few times I've thought, "definitely going to be getting a ticket there" after driving on some of the motorway network but thankfully I've still never had anything but a clean license. I think some of the methods they use to catch you speeding are a bit crafty and although I don't condone speeding, most people's attitude to the speed limit on a motorway is a bit more relaxed.

If there isn't any notice of speed cameras on a motorway or any temporary limits, I stick to about 80, yet I'm still overtaken several times a minute with it being obvious some people are going well over 90. I've heard the traffic police won't bat an eyelid at anyone going under 90 because they know if they come after you for going at that speed then they know they'll miss someone going over 100.

I think the speed limit could easily and safely be raised on our motorways, or at the very least have a dynamic speed limit that changes depending on the road conditions or how busy it is. They do already have this in place in parts but obviously the maximum limit is 70. Car safety has come a long way from when the limits were introduced and we have some of the safest roads in the world, the biggest menace for me are the people who just managed to scrape through the driving test but haven't ever really got the feel for driving, people who drive in lane 2 of the motorway regardless of what's happening around them (I wouldn't say there is never a case for sticking to lane 2 for certain periods of a journey) and those who drive like nobs at crazy speeds everywhere with little regard for themselves, other roads users or the highway code. Unfortunately due to these groups of people the speed limits will always be well inside the comfort zone of good, experienced drivers.

I will say though, when you're heading towards 90mph you don't half start burning your fuel in massively disproportionate quantities to the speed increase.

 

You've been lucky then so far mate. The threshold is 57mph, if you average 58 or more you get caught.
