Anti Gatso Number Plate Spray
Discussion
the laser will never deflect downwards.
The ballatino at the back of the plate always reflects the light back in the direction that it came, unlike a mirror.
Anyway, gatso's don't use laser. They are K band radar. The camera photographs normal light so you can't block it with IR filters either.
ACTUALLY, you've given me an idea!

According to nel's theory, a proportion of incident light is reflected at each optical interface. Therefore, if you were to cover your number plate with a series of layers of something transparent, you'd be creating a series of interfaces and could potentially render your plate non-reflective to a camera flash.
Have been meaning to try this - to make an optical interface you need a change of density and a nice shiny surface, e.g. very thin layers of plastic glued together at the periphery to create a thin, multi-layer laminate with a series of air-plastic-air interfaces within it. I reckon that this would be effective, particularly for an offset flash, i.e. incident light not normal to the plate.
Obvious concerns - would it be obvious in terms of the appearance of the plate when illuminated by headlights or natural daylight such that you get tugged? Oh yeah, and am I talking shite?
Anyone out there played with this?

The only thing that appears to have an effect is to have a tilt on the plate so that the laser deflects down to the road.
....like wot Bryan said really. Bryan, whats's your idea?
my idea,
is that your number plate is pretty bright in a Gatso photo cos of the corner cube effect of the ballatino.
SO, if you replaced the balatinno with something the same colour but NOT ballatino, then to the naked eye the plate would look the same, but from a flash gun the photo would look much much darker in those areas.
So, make an 'F' look like an 'E', 'I' look like an 'L',
'R' look like a 'B' and so on.

no..doesn't work...
I've got input in a 'think tank' for UK prosecutions and there isn't a recorded case of a gatso/truvelo activation where the registration plate cannot be read due to anti-reflective plate or spray
despite the availability of such things for several years on the internet

hiya Roadcop,
is it not true that you cannot do a wild card search for a number plate if any part of the plate is unreadable eg broken, covered in dirt etc?
Though you could give the suspected car a visit at home, you can't use the photo as evidence?
Hiya Bryan..
Aye...you can do such a search on a variety of databases...with very little info..
The more serious the offence, the more time will be taken to search...
For a letter or two missing; it's very easy...especially with colour, make and model known...
As for other things; if there are any distinguishing features, it can be used in evidence;
sun visor strips, tax disc holder, stickers, location/colour of rivets in number plate etc etc..

You can tilt the plate downward to make it harder for the laser operator but as someone already said, the reflective backing will still reflect it back. So the obvious thing is to use a non reflective plate tilted down.
Ive used this for ages, hell it even works on anpr, in they dont get a lock...downside? they send half a dozen plods after you to find out if youre illegally driving etc.:hehe
Small price to pay for some peace of mind.
However think about this for a second. What else is reflective on the front of your car? Yup the headlights. And thats where they aim next.Get a different mota!

My sister is a Plod Civvy.. on a training ex they showed how easy these "sprays, illegal plates etc" are to decode. About 10 secs per plate. With a tea break in between - lol

What about this - likely to fool anyone?
To get away with it, you would have to turn off the plate at the point of being filmed.. If you are going to do that you may as well slow down for the scamera anyway...
Once you are caught by a copper, he is not going to "let you off" if you turn off your number plate is he???
