It will depend on how it's programmed.

If the programmer was given a tight schedule and not paid enough I, sorry he, would probably just look for a bright yellow object then try to decode the letters in it based on the correct standard font. Silver & black can go away, I can't be arsed with figuring out if it's someones tshirt or a car.
Could also depend on whether the programmer knows that there are any other style of number plates biggrin

I also could not be bothered to even look at the plate on the front of the car. Rear plates only.
In the car parking case viewing rear number plates could be difficult, there's frequently a queue of traffic in or out and the car behind the one you want to see could be too close and obscuring the number plate.
On the other hand, around here more and more cars seem to have decided that they don't see front plates on You Tube so they can't be required and have just given up on them.

My local supermarket has a screen which flashes up your registration & the time of maximum stay which cannot read my Morris plate. I guess the ANPR are a little more sophisticated so I wont be testing the theory on them.

Thanks all, so it seems likely that simpler systems like supermarket car park readers don't seem to recognise but potentially more sophisticated systems will. I have silver on black plates on my '72 Alfa. Whether its sods law or tempting fate, I got flashed on the A3 early this Sunday morning. So I may possibly be able to solve this myth shortly! I also have silver and black plates on my '63 Morris but the chances of me bending any speeding laws in that are very slim!

Not the same with Dartford crossing unfortunately
Yep, Dartford crossing picks up my cars - which would be fine if I could remember "I need to pay the charge" for more than 30s after crossing the bridge...

You got flashed by a static speed camera. It will have taken a pic of your Alfa and thus an operator will be able to see the reg and you will get a NIP.

ANPR reads a plate as you go past the camera(s) and then works out your average speed. It would appear that the ones on UK roads are not set up to recognise Black/Silver plates so a classic is in effect invisible.

I can report that the Dartford crossing ANPR CAN READ classic plates.

I got caught on a fixed speed camera some years ago. Black and white plates on a DB6 which the machine had no difficulty reading. 34mph in a 30 mph as I recall.

Ah, so the speed cameras actually have a human element with someone reading the picture? Is every picture read or just the ones that can’t be automatically deciphered?

I believe they use an automated process but then flag any anomalies for an operator.

Urban myth I believe - I’ve had experience of car park readers not ‘seeing’ my silver on black plate, but I think that was more that it couldn’t compute a ‘72 reg number.
I have a 74 registration and it’s on yellow plates as it should be.

Never once had an issue, I think it must be your black and silver plates.

Fair enough - I'm only going by what one or two of the attendants in said car-parks told me, but the issue may indeed just be the colour scheme as you say. As it's a pre-73 car and wears its silver/black plates legitimately, I don't feel inclined to change them anytime soon.

I can confirm that multi storey car park type cameras, can't read the white digits on my front number plate.

I can also confirm that my car with this style of number plate will fit under the said car park barrier if I duck my head a bit.

I would not like to comment if I have used the above two bits of information at the same time.

Pretty sure ULEZ and Congestion can’t pick up black and white plates

Ive got done twice for speeding in an E type with old black and white plates-though cameras.

So its an urban myth as far as I am concerned.

Possible they had human intervention?

Speed cameras are not ANPR cameras.

Impossible, a human would have said 'go for it PP' on seeing an E Type.

I was just about to mention my experience (and that I had started a thread about it).

Not sure if it automatically picked up the registration or not though.
