UK Police in Holland?

I was driving home and was being overhauled by a group of British motorcyclists.
Nothing special, but….
then I saw the jacket of the last driver… huh… a British police officer??
Here in Holland???

It was just a split second before I read it correctly…

What a nice idea to draw attention to a safety message by letting it resemble a Police jacket.

Downtown Haarlem I saw the same guys again as the stopped to find a pub, so I had a brief chat and took this photo.

They came from the TT in Assen - our most important motor cycle races event - and were on their way back home in Sheffield /UK

ps. Police is 'Politie' in Dutch, which resembles Polite even more ;-))
