How close to go safe van before your caught

xabi

Driving on a dual carriageway today doing slightly over the limit, 4 or 5 cars in front of me when i spotted a Garda go safe about 100 meters or more in the distance, it flashed but im wondering at who, how close do you need to be? I'm guessing it was one of the cars in front of me, we were all doing about 110.

I would have thought when you can see them they can get you.

If you were doing 110 in a 100 it wasn't you

C.K Dexter Haven

I've seen program's saying 1km. The usual saying is if you see them it's too late. If this happens to me, I usually pray that the guy in the back of the van is either setting up or packing away the equipment

Still 10% + 3 apply. Last year I was doing about 1.5-2k miles a week. Used gps to keep as close as possible. Stayed at 10% extra to give space for wandering speed up and down.

Never got a gosafe. Closest it got was a garda with a camera waving to slow down but no pursuit

I dont think this has ever been a hard and fast rule, has it? That would mean that you would get away with going 135 on a motorway, which you almost certainly wouldnt.

Id never go right to the limit of it but I was always grand at 130-132

Can the speed vans get you from both sides or is it just from the back of the van?

dgt

Both sides

familystand

I had a tour of a go safe van at my workplace, They set the cameras to the limit so it snaps every vehicle exceeding the limit , They operate 24/7 with infa red technology and the rear facing camera gets traffic going in both directions if on a normal road
They upload ALL images to the GARDA system , The Gardai decide who gets done, The camera records your vehicle from approximately 45 feet from the rear of the van, watch one of them setting up sometime , they set up a tripod to set the camera to record from a set distance from a stationary object , namely the van.

That cant be right like are the gardai going to look at every one going 102 kmph. Seems a great waste of time

They can get you both ways from the back but they do not have a camera at the front of the van afaik.

At least I've managed to spool off speed by the time I passed the back of one and I've never heard a thing back about it

shooter88

There is a website and app to check areas where speed cameras do be..
I'm lucky the bit of road near me they use is after a slip road so I'm never above the limit where passing and comming the other way you can see the roof of the van before it sees you

What?

duinegorm

If your are over the limit, see the van in the distance and then stop and don't pass it ie. use another route around it. Will that mean the rear camera that takes the pic of the license plate will be of no use?

Don't break the speed limit:D:D:D:D;)

That's nonsense. Literally.

The speed sensor picks up your speed reading at about 120-100m (depending on your own speed) The camera then photographs you at roughly 30m. I was told that by an employee of Go Safe who is a very good friend of mine.

The cameras are limited by the distance the can "see". They are only guaranteed to be able to photograph a moving number plate at 6m. The Garda car, by way of contrast can see & sense you at 300m

Reason they can't is they have to take away for speedo inaccuracies.

Which is why you wont be done for going 2km/h over the limit. However suggesting that they will allow you to go as much as 15km/h over the limit is pushing it somewhat.

Unless your speedo was gps fed its impossible to get it accurate. Tires are different size between brands, even tire wear will affect it. There are loads of stuff that affect a speedo. If a speedo isnt accurate they need a % to ignore so after that your definitely speeding

GoSafe, between Shannon and Limerick. 2 points for original offence, (110 in a 100 zone) and two points becase she forgot to pay the fine on time.
If I find the paperwork I'll scan and post..... to be honest I was fairly sure it was for 108 in 100 but my wife swears it was 110

corkgsxr

Maybe you were unlucky but I used to pass them daily at 110 and never got a ticket. And I used the gps for speed.

We were alway is a fierce rush. 5-10 mins saved between jobs adds up and you get home sooner. Used to consistently get 36mpg in a 09 2.0 caddy which considering the way it was drove is good. A tank of diesel wouldn't last 2 days.

Glad im out of that job

Except buses and trucks, their speedos are calibrated and are accurate. All other vehicles are permitted to over read by as much as 10%.

No they don't. If your doing over the limit your going over the limit, simple as.

Where your getting confused is the fact a lot of speedos under read by up to ten percent. So if your doing an indicated 135kmh your still actually doing slightly more than the indicated speed limit of 120.

10% both ways. Your speedo could be under reading too. Thats why I used to use the gps to do it without guessing what the speedo is doing

No it cant. EU law states manufacturers cannot let it be less than actual speed.

Speedos are allowed to overread, but not to underread. This is why almost all car speedos read 5-8% more than the actual speed.

Fair enough but iv always stayed at the 10% extra and never got a ticket. And id pass at least one a day

Not so. The indicated speed must never be less than the actual speed. Otherwise we'd all be blaming the car manufacturer.
(There's also some limit imposed on the permitted error on the over-reading.)

So much of this thread is utter nonsense, hearsay and pub talk. Especially the bit about seeing it in the distance and going in another direction, and Garda cars with 300m range. If you want to defeat these things at least understand the tech involved and it's limitations. It's not difficult.

How accurate are the signs which say slow down watch your speed and tells you what your current speed is......there is one on the N11 in Wicklow.....and i always get my speedo bang on 80km/h .....but the sign always displays 72km/h

mikeecho

Long and short of it:

The Camera and Radar beam are angled at 22º across the road.
The radar spreads at 4.5º

(can someone do the maths please)

You must be within the radars beam for a speed to be taken.
The picture is taken at the same time.
The picture is actually a still, as the camera is a video camera.

Because as already stated here your car speedo can overread by up to 10%.. ie sign shows your actual speed vs speedo's inaccurate reading.

Thank you for summing it up as has been down countless times here. There is a decent video on YouTube if someone wants to look it up.

Really roughly, the Maths equates to, if the van is monitoring a 10m (~30ft) wide section of road (i.e About the width of an average two land N road), you'd have to be closer than 24.75m (~75ft)

Bear in mind between 80 to 100km/h you'll cover that distance in just about a second.

So in other words, you should in theory have about 3 seconds (i.e. 100m) to see it, slow down and pass it as under no reasonable circumstances are you going to turn a corner and it to be 'just there'

Because your speedo is over-reading. Most car speedo's over-read the faster you are travelling. No car speedo, as has been said, will ever give you a speed faster than you are travelling. Thats in EU law. If you car does this its not to spec.

For instance, below 50km/h my car is dead on. 63km/h (Speedo) is 60km/h true speed. 125km/h is 120km/h true speed. I personally wouldn't allow 10% as in most cars its far closer to 5%. I would doubt any car would over read by 10% with stock tyres etc.

The reason Uncle John wasn't pulled for doing 110km/h in a 100km/h zone was probably because he was doing about 102km/h in reality. GoSafe Vans have a 3 to 4km/h tolerance I'm lead to believe. So in my case, at 111km/h in a 100km/h zone I'd be right on the margin (I wouldn't however do this, far to close cut)

If anyone really wants to get the most out of their car in this country (Speedwise) you'd probably be wise investing in a proper GPS trip computer. Most are accurate to +/- 0.22km/h. An iPhone or similar is probably close to +/- 1km/h

Your speedo is over reading.. it is showing your speed as being over actual speed therefore over reading.

Is the picture of the reg not taken from the rear when you pass the van seeing as that's when the flash kicks in?

You cannot see the flash. Its infrared. You may see a slight flash in certain lighting conditions and you may see a flash from a Garda van. However seeing / not seeing a flash is not a indication of whether you were caught or not.

They take photos, from the rear of the van only, of traffic going in both directions (If applicable)

@ ironclaw

is it time for an updated sticky ?

I can do one up with your info/ pics, adding some tech specs.

but I'm afraid the tech specs might confuse some, and irritate others who believe certain operations are calculated differently.

Wouldn't do any harm. I'll do one up if you like and if you want to PM me any info.
