Can a moving Garda car coming towards you detect your speed?

Irish_peppa

Hi Guys
Just curious, can a garda car driving towards you on the opposite side of the road detect your speed? Reason I ask is I think i was a bit too quick 15 kph over the limit today (i know im sorry) when a garda car appeared on the opposite side BUT nothing happened. Maybe he was too busy going somewhere else?

Nothing will happen. They haven't stopped you.

There is even a chance they were doing 15 over just like you.

No they can’t detect as it wouldn’t be accurate. Also if they had a speed gun and you weren’t stopped they don’t have evidence like a picture or video footage.

Yes, the new Doppler Effect Speedguns have Motiontechnology™️.

i thought they might have a dash mounted speed detector that could calculate their speed and the closing speed of approaching cars and work out the other cars speed
my imagine running wild

So in theory IF i was speeding towards them which they noticed and came after me for, can you be charged with speeding but without any actual evidence only the testimony of the guard ie : "Peppa looked like he was bombing it judge i didnt use a speed gun but i could tell visually he was double the speed limit"

No

This is the wild west country where a Garda can prosecute you for speeding on his or her word alone. They don't need calibrated equipment (or any equipment at all). He or she can stand in court and say "I think they were doing 100 km/h" and the judge will believe them. It's madness, I know but that's how it is.

Even if a Garda pulls you over and you show him or her your licence, they don't even have to tell you that you are getting points and a fine, you just know when they arrive in the post.

So theoretically, yes, a Garda can send you points and fine in the post if you were approaching them in your car.

As I said, welcome to the wild west.

They can't just send you a fine and points based on their observation on the road without stopping you first. . Even if there is a loophole it doesn't happen.

Found this on the web
you can only receive a speeding fine and penalty points through the post when the GATSO ie unmarked van on the side of the road with speed detection equiptment on board or static speed cameras detect your speed and produces photographic evidence to prove same in court

Apologies. I stand corrected. I wasn't fully aware.

Technically it's easy to do (doppler shift), but I doubt Garda has the technology.

Because they using the laser, it is no problem to detect your speed. The radar needs only the accurate garda car speed and it counts easily your speed. Does not need anything fancy because the speed of light are almost 300,000 km/s. So the laser side does not have any problem to detect your speed very accurately. Problem are the garda car speed, because they need to use wheel speed sensor feedback directly. If they using it trough ECU, they get wrong readings. ECU process that data and it is not anymore accurate on ECU output data. Easy test, put the oscilloscope and the obd2 scanner side by side. Connect the oscilloscope directly to the wheel speed sensor feedback and obd2 scnner set the graph mode and read the processed data from ECU. You get the slightly different readings.

this question comes up a lot in relation to Garda cars.

If you're speeding and stopped then tough.
If you're speeding and not stopped you're grand.

Vans(either marked Gosafe or unmarked GATSO) take photos. You'll receive a fine if speeding when you pass one.(not all the time )

What if you are overtaking a large lorry and the speed van appears in front can they get the speed of both vehicles? If it is just one target then I guess you can argue that the lorry affected accuracy??

The laser is so accurate, there is no any excuses.

I believe if there are 2 vehicles in the photograph they won't prosecute.

On that topic if you are heading towards one with another vehicle beside you but going over the limit i PRESUME it picks up the faster of the two. Or if the two vehicles are doing the same speed it picks up both or just one?

I would have thought this would be easy to implement with the correct equipment. If you watch police Australia and NZ on Dave, can't remember the exact program name, they regularly pull people over for speeding and the cop car would have been travelling in opposite direction. That program is at least 10 years old so the tech is very much available.

Couldn't they just use the same radar to get the speed of the oncoming vehicle and the speed of an inanimate object? Ie sign, wall, tree.

It doesnt really matter. The reason for lack of enforcement isn't practical it's political. Ultimately every cop car could easily OCR cameras that read number plates and check databases against stolen, untaxed or uninsured vehicles. They could cheaply deploy average speed cams at every entrance of the m50, and simply timestamp your tolls for longer routes.

They could make the roads a nanny state. They haven't yet, I think we should be thankful.
