I remember a case against the Garda van. Was along the lines that Flash was distracting and blinding towards a driver. Infrared would actually be better for night time contrast.

I can't honestly answer but I know in day time, the Garda van has a flash.

can anyone confirm if these gosafe speed vans flash during the day?

I passed one doing about 55 miles per hour in a 50 miles per hour (80km) zone leaving Tipp town at 9am while heading to the train station.

I didn't see any flash. Perhaps it did but I didn't see it.

The problem is two fold:

1) Was it a Garda or GoSafe Van. Slightly different tech invovled

2) How accurate is your speedo. At 55 you may only have been doing a smudge over 50, so giving a small bit of leniency you might not have been speeding at all.

They don't have to flash however. Given weather conditions, lighting conditions etc it might not be necessary. Think about any normal camera, flash only comes on in certain conditions.

It was a GoSafe van. (not a white GoSafe van as I expected. I think it was purple or had purple doors on the back, with camera stickers on the side. Also camera was clear to be seen when I passed back window).

Not sure of the accuracy of speed. It happened so quick, when I took my foot off the gas and looked down, I think I was at 55 miles per hour. But presumably by the time I see the van, the camera has already snapped the speed regardless of me breaking. I may have been doing 58 miles per hour but on slowing the needle was at 55 for example.

The car is a new to me a few days and don't know much about its accuracy. I should probably install a GPS and compare speeds.

Have you any idea of how it takes to get notification? I think in the UK they have to notify you within 14 days.

Hi Folks,

Few updates for people.

Do They Flash At Night?

No, not visibly. They use an Infrared Flash on the top of the van


Can You Detect Them?

Not legally. In addition, tests have shown you won't be able to detect them at a good range (400 to 200m) without spending serious cash. This is due to their extremely low powered K band radar.

Slow down, its cheaper

Interesting video.

Pardon my ignorance, but in relation to the example above how exactly does the GoSafe technology distinguish which vehicle is speeding? In this case both vehicles are passing the camera more or less at the same time. The flash is triggered by the faster of the two (assuming the vehicle being overtaken is within the limit) but presumably both are 'in the frame'. Does the system select the speeding vehicle automatically, or is there some human judgment in the process?

Bit off topic but can the go safe vans park on the hard shoulder of a motorway? Can it park in the Garda speed ramps on a motorway?

Ironclaw thanks for all the info so far, one thing you mentioned a while back was about it not working in snow, wet etc...

Can you elaborate on the 'wet', does the gosafe radar not work in the rain?

With regards to this video, the car with the in car camera triggered the van but the guy over taking would technically have been going faster. There is a guideline however if more than one car is in the same photo, the offense is disregarded. Simply because it could be either of the cars e.g. Reasonable doubt. This is extremely unlikely to happen so its not a hard and fast defense.

To answer your question, the van targets a particular car and snaps if over the limit. The human aspect would be like the above e.g. More than one car in frame etc.

Good question. I'm probably wrong but its illegal to "park" on a motorway unless your conducting work or the Gardai. As such I would imagine motorway use is a no go as they would be committing an offense. I'm open to correct however.

Its a IR flash. Video camera's pick up visible and invisible light, most noticeably in the UV and IR range (Just outside your eyes range) The driver of this clip saw no flash but it appears on the video. Hence IR flash. If they used a "real flash" it would be blinding and dangerous for drivers. The unit I would imagine doubles as a real flash as well. But as I've said on other threads, IR is actually better as you can get a better black-white (e.g. Number plate) contrast.

Laser can't be operated in extremely high humidity. You'd want it to be enough precipitation e.g. rain, snow or sleet so that your visibility would be affected. Put it this way, ground radar at airports is affected by precipitation so you can only imagine what it would do to a lesser radar. I wouldn't use it as a legal defense but it would call the accuracy into disrepute as the radar / laser would be bouncing off particles which would distort the return (Note: The units have a built in tolerance for this)

I've been wondering about their "tracking" ability.

They're supposed to work for hundreds of meters, but the camera won't focus or get a good picture at that distance.

What would happen if you were doing 20km over the limit and you spotted the camera 300m away. If you slowed to the limit quick smart, by the time you got to the "taking a photo" range you'd be doing the limit.

Does it measure your speed in the instant that it's taking the picture, or has it the ability to lock on to a distant speeding car and remember to take a photo of it even if it's reduced its speed in the meantime?

hello all.
I passed what appeared to be a speed van today.
However, there was not writing or identification labels on it.
I understood that all of the new mobile vans had the camera synbol and identification/luminous lining on the van.
There was what appeared to be 2 lights in the rear end. I was doing 106 km/hr in 100km/hr, would I have been caught or is there a tolerance . cheers

Covered on lots of speed camera threads here....But in short garda vans & survey vans don't have to have any markings on them. And no there is very little tolerance allowed any more.

Whatever about a 'tolerance', the odds are that your indicated 106 was actually less than 100. My 2c is that you won't get the dreaded letter.

Hi Ger,

You've already asked this question in several threads.

Could you keep the discussion to one thread please? The Speed Camera Mega Thread preferably.
