Not an operative as such...

According to an article in the Irish Mirror (not sure how credible a source

"If a motorist can see the speed camera van, then they are in range to be tracked for their speed. A motorist driving towards or away from the back of the van can have their speed monitored."

There's a bit more info in the article. I'm sure you can find it on the web by doing a search.

Sticking to the speed limit is always your safest bet

I just wish drivers in a 100kph zone who are at the legal limit, wouldn't slam on their brakes every time they see a GoSafe van. It's fuckin dangerous!

I believe there's a 2% discrepancy built in. It used to be higher. But I can't remember the source.

It's interesting actually because I often travel with Google maps on my phone navigating regardless of whether I know where my destination is.

The discrepancy between the speed read on the speedometer and what Google maps tells me is massive!

I wouldn't be surprised if the speedometer of cars shows that you are doing a higher speed than what you are in order to reduce the number of speeders on the road. Or that would certainly be the indication of the discrepancy depending on the accuracy of speed measured on Google maps and your car.

I'm not saying this in order to encourage speeding!!! But try it yourselves and see what your results are in the difference between your speedometer and what your Sat Nav tells you

It is...but it's the sheer scare of "shit, did I stick to the limit

and slamming the breaks.

Thank f**k for cruise control - greatest invention ever for long journeys and motorways/dual carriageways!

Taking into account the gps lag, a sat nav will always be more accurate than your speedo.

The speedo relies on the number of times your wheels rotate but that can be affected by wear on the tyres.

A speedo won't underestimate your actual speed though and will always be higher so err on the side of caution.

Incorrect, traveling in either direction detection is possible and up to 6 lanes simultaneously in different directions of travel. Coming towards the detection van produces the speed, traveling away produces a negative value of the speed.

Most of the speed sensors are from a Dutch company, the home of speed cameras. There are various types of sensors, the gun type are the most effective and have the longest range. The van type sensors, can be quite pathetic in detection, but dont push the theory. They are more effective straight on to several 100 mtrs but fall off rapidly when detecting to the side. As mentioned GPS's are good for maximising your speed as their accuracy is typically 1/4 mph, where as speedos can be as high ad 10% or worse if slower than max speed, actual error to be confirmed.

Think you’re correct Re the 10%. I drive on the motorway a nice bit, always set cruise control to 130kmph, have passed a few speed vans over the years without braking (mad bastard that I am) and have yet to receive any motorway points! It’s the 50/60kmp zones that really catch you on the hop…

Those go safe vans don't have the same tolerance as normal speed vans, as i stated above I was told this by a Garda officer when I was done

I travel on average 60k a year so those go safe vans are the bane of my life, espicealy where the limit is 50klm on a straight country road going trough a village that stretches for 3klms. Church at one end then a few houses then a field the school is next and then another firleld befor reaching a petrol station and shop with a pub opposite and getting done for 7 klms over the limit.

Having asked a gaurd, a go safe opperator and a solicitor they all say the same as soon as u see the van stand on the brake the sudden reduction in speeds seems to confuse the camera

Yes this has kept me below the maxium alowable amount of points on more than one occasion

Just a word of warning dont read the Indo on your phone while sitting in a traffic queue, its attracts 3 points if caught even though the van was out of gear and the hand brake was applied

Yeah, the vans pick up your plate from up to 1km away (presume a straight stretch) , it takes a pic of your plate...if you're doing over the limit and keep that speed it'll process you...if you spot it and slow to under the limit within a 100m, it won't process as it needs you to be consistent with your speed over a certain distance to do this. If you slow, it'll wipe your number, as you are within limits

Not sure but as far as I know if you can see the van in a straight line the van can see you. Also the van has to have you in its line of sight for a certain amount of time so it can work out your speed. And there is a tolerance because every cars speed is calibrated different and so is the equipment in the van to read your speed

I'm not sure if Google maps is absolutely accurate but it is mostly likely the correct speed.

Car speedo designers don't get the budget a gps satellite operator does and accuracy costs money.

A car speedo is reading speed based on the rotation of the wheels and if the wheel size changes that throws off the calculation. That's very common when people over or under inflate their tyres or changing the wheel and tyres size from stock. So as a manufacturer you are going to design some slack into the system so that you won't be sued.

Speed cameras will also have a built in tolerance due to cost and calibration accuracy because they don't want to be in court trying to explain that it could be borderline wrong.

You can kind of have a simple rule of thumb to know what you can get away with like 10% over the dash is still safe but the reality is based on multiple factors mostly unique to your car that can change over time.

Unless you have a modified car that fails an NCT you have no reason to slow if you are doing the speed limit according to the dash.

The nerdy phrase of the day is "tolerance stacking"

Majority of them are like shooting fish in a barrel, parked outside a 60km zone and people ge their speed up on the outskirts of a town and there is a van as you round the corner. Of course if you drive within the speed limit you won't have an issue. However in terms of placement of the vans, majority are not on known black spots at all and are places in areas where they will get easy captures.its a business after all.

Never mind the 100 zone, they do it on the motorway and go slower than 120!

Fitted slightly higher profile tyres to a commercial van.Gives much better comfort. Just worked it out. My actual ground speed has increased by almost 5%, but obviously my speedometer doesn't reflect the increase. Just a word of warning for others - the allowable speed tolerance has been used up by the larger tyre.

My van originally had 15" steel wheels but I put a set of 17s on it.. I wonder is the speedo not reading accurately now.. I didn't put much thought into it..

If the total diameter, that is tyre and wheel, is greater than before, then yes.

Some put on bigger wheels but fit lower profile tyres to keep the diameter the same.

Basically if one complete revolution of the new tyre ie. the circumference - is a bigger measurement then your speedo is not reading correctly.
