Anyone been caught by average speed cameras?

[86JR]

I wondered about the HGV thing as one tailgated me through at about 2 feet from me forcing me to accelerate, he did this for ages untill near the end when he tried to overtake lol.

The a38 ones : i drove back in the dark at around 1am on Saturday and they still werent doing any work lol ? Is that because of the weekend though ?

 

[Overlag]

have you not read his post ?

how can they work out an average of his speed if the first camera never read his numberplate ?

he's saying that as he goes throug the first camera, he tries to hide behind lorrys etc.. to prevent the first camera from seeing his plate.

yes i did read his post.....

To be honest I try to be sneaky through these, I tailgate lorries when passing the first camera, my numberplate is very low down on my car so there is no way the camera can read it - then speed up through the main section before slowing for the final camera (in case they can issue a fine for a certain speed past a single camera). Not been done yet and have been doing this for months on the M5.

he THINKS each camera messures the speed which is NOT the case, they just log a time, and work out avg speed between 2 points. they do NOT messure speed at the camera itself. Maybe you should read the posts more?

this is because the HGV's speedo is probably reading correctly so hes doing dead on the speed limit where as your car will over read. You may think your doing 50, but may be doing 45 etc? Or maybe it was a foreign lorry driver who don't care about silly UK speeding tickets.

Just out of interest, why do they sometimes have loads on a stretch of road rather than just two or three if that's how they work? (I'm not disputing it btw, just wondered).

Think it was on the M1 a while ago, I saw what must have been at least 6 with no junctions in between them.

In my experience, going through a specs stretch of road with my limiter set to 50MPH (or whatever the limit is) invariably means I find myself catching up the car drivers who still insist on braking when they get near the cameras (even on an "average" stretch) usually, I can easily pass other cars without exceeding 50MPH, glancing down into something like a Citroen C5 I can often see the dash and the car tends to be doing around 58MPH indicated (a lot of Citroens have digital readouts for speed on the dash, this shows up to us truckers especially at night)

 

[Matt82]

i find this too. it seems to suit truckers best if i do "vw golf 50mph" in lane two, so they can do "big lorry 50mph" in lane one and not have to faff abou with over taking

i thought lorrys went through fast because they knew none of the cameras worked

I think you got it slightly wrong in this instance. He knows the camera dosen't measure speed, only time across points to calculate avg. speed. If you avoid the first camera then it cannot calculate the average speed, if you don't know what time something entered the zone how can you calculate the avg. speed on its exit? By hiding the numberplate behind a lorry the ANPR camera can't read it thus your entry or exit was 'invisible' Hes just doing that last slowdown in case the cameras can also measure speed via the old radar method etc.., which is wrong of course but i see a lot of people doing it anyhow.

read my post again

how the hell can it measure your speed between 2 points if it never saw you go past the first one ?

it then has an end time, but no start time with which to calculate the average speed.

so it can average you out between multiple points, and to catch people that tailgate lorries to try and get through faster.

oh my...

i know that, but hes STILL slowing down for the 2nd camera just incase it messures his speed. which is what my first post is all about, then my 2nd post explaining it to you...

this is basically what ive said in all my posts yet Mrlol and now you are argueing against it, even though you've said the exact same thing only in a much longer paragraph. The underlined section of your post is what ive been saying all along. Yet you both question what im saying....?

also if He knows the camera dosen't measure speed, why is he Hes just doing that last slowdown in case the cameras can also measure speed via the old radar method etc?

also you say he knows the camera doesnt measure speed but he said:

(in case they can issue a fine for a certain speed past a single camera).

this is the point im contesting, not about him hiding his number plate through 1 camera...

i thought it was because they often have more than just 3 cameras? If they've, say 6, over a stretch of road then even if the 1st one misses the 2nd, 3rd, 4th 5th and 6th will still get you and be able to determine if you're speeding.

only 18 detections with tens of thousands of cars along this stretch of road each (day) week

More likely, ACPO threshold is 57mph, HGV speed limiter is 56mph, therefore no need to take any notice of the cameras or the new speed limit.

Oh and with the updated SPECS cameras the tailgating a lorry trick is only guaranteed safe if you do it for all but one of the cameras.

That was the plan but on this stretch it forces you to choose lanes and then stay in that lane.

I was done last year on a section of the M3 Twickenham end, roadworks with an average speed limit of 30mph which was ridiculous. Was clocked at average 36 according to the letter, ended up taking an option to go on one of those speed awareness courses in Chiswick at £100 where everyone else on it had been caught in the same place.

Complete waste of time and a big rip off imo.

 

[Mr Jack]

There is some margin on them, I usually do 52 (Tom-Tom reading) through them and nothing yet.

 

[Totality]

These cameras actually make me angry. I am a firm believer that if people are working on the road then fair enough, but 99% of the time I'm slowed down to 50 on the M3 and M4 and have never seeen anyone doing "road works". Why don't they just turn them on when people are working?

When I was in the states, fines were increased when people are working but reduced speed limits were turned off when no workers were about.

They do on some roadworks. You get a little yellow sign saying "camera not in use" in this case.

You can see this at the moment in the various roadworks on the M4 between J13 and J7 or so.

 

[Bennie-Mac]

In northern ireland we have the longest stretch of average speed cameras in the UK. It was reported in the papers that in the 1st year of being up only 1 person was caught and ticketed!

The speed limit is not there to protect road workers - they as likely to be killed when hit at 50mph as 70 mph. The speed limit is there as signs can only be made large enough to be read at a max 50mph; temporary barriers are only adequately safe for drivers up to about 55-60mph; safety zones to cover wandering vehicles are safe to a max of 50mph; a cone hit at above 50 mph is likely to cause an injury accident and its difficult to stay in narrow lanes for any length of time at 70mph.

If you do some searching you can find some good footage of a idiot who hit a temporary barrier at 80mph+ going sideways. The back and front of the car were pointing roughly in the same direction.

They have these on the A38 now just past Ivybridge area going towards and coming back from Exeter. National Speed limit road, limit to 50mph. Yet they arent doing any work. Been through it 3 times in 3 weeks and they arent doing work, just a generator in a closed off layby. Police short of fines or something ?

have experienced this far to many times in the last week! so so very annoying! Girlfriend works near Heathfield and we live in Plymouth at the moment, and in the also in the last week been looking for a new flat/house to rent near her work...so driven to and from their twice a day for the last 4 days in a row, one trip in the morning and once in the evening, not seen anyone doing anything in the morning, and in the evening seem to get stuck behind a digger driving up the road each time! really, complete waste of time and money, i dont see why for the moment whilst the road isn't dug up and no workers about they dont turn the specs off and then in the evening when they move the traffic onto the easbound carridgeway turn them on!!

Its invariably because HGV's have calibrated tachographs (speedo in other words) so when they are doing 50 indicated, thats the speed they more than likely are actually doing.

Most cars do not have calibrated speedometers and they tend to read fast sometimes by quite a margin.

More likely, ACPO threshold is 57mph, HGV speed limiter is 56mph, therefore no need to take any notice of the cameras or the new speed limit.

This also.
