Why? Seemingly pointless sign

[pikey]

On the Blackwall tunnel's Northbound approach and Northbound exit there are some new (strange looking) cameras and these are accompanied with large signs saying "these are test cameras, no enforcement taking place"?

Why? What's the point? Who cares that they're test or live?

Every time I drive past them (or crawl, as is usually the case with that tunnel), it bugs me!

Any ideas?

They are pollution 'cameras' to catch wagons and buses etc that overpolute.
Eventually they will start fining pollution abusers..

which if that is going to include buses makes me wonder if there is any joined up thinking in any of the govt policies...

silly me of course there isn't.

That's just fine (there are some pretty nasty lorries around there), but why the sign? A job for the bloke employed to make signs perhaps?

Probably to stop people standing on the brakes thinking they're likely to get done going to fast...suppose they could have saved money on signage and caused a few fender benders instead....

The words "fast" and "blackwall tunnel" don't go well together. In fact any speed in excess of 2mph is a bonus!

It is an indicator for all illegal vehicles, immigrants, drug dealers, suicide bombers that this the preffered route into London.
This will of course reduce the amount of crime detected/prevented and contribute to the statistical success of the current government.

They are cameras getting ready for the new emissions based congestion charge. They'll recognise numberplates and cross check that with the gas guzzler database. Why the pointless sign though I couldn't say!

btw, it's outside the congestion charge zone (that's the CURRENT congestion charge zone - it'll probably incorporate this road next year!)
