Sauce for the goose ...

Shortly before sunrise this morning, while travelling at the speed limit of 60 miles per hour on the A66 near Keswick, I was overtaken by a large van painted with a striking pattern which designates a particular type of official vehicle.

And would anyone care to guess what sort of official vehicle was breaking the speed limit in dark conditions?

You've got it: a safety partnership speed camera van.

Quis custodiet ipsos custodes?
