UK-POLOS.NET - THE VW Polo Forum

The tax checks always have signs on or near the vans saying what they're doing, and also a copper up the either side of the van to pull people over who were caught by the cameras or who suspiciously did a U turn as they noticed what the cameras were doing. Obviously on a motorway no one's going to be doing a U turn, but did you notice a copper waiting by the hard shoulder a bit further down the road?

Agreed yeah, ther're called ANPR and have that on the side, also as GroovyCarrot said, they'd have 1 maybe 2 patrol cars waiting for when they find a dodgy one.

nope, didnt see any police

very sneaky, i went under the bridge then about 1/2 a mile down the road there was a copper just parked at the side of the road, moment i passed him he followed and pulled me.
