Do not U-turn

Sometimes, when I really need to make a quick
U-turn near the office, I have to be very careful
as you cannot do the U-turn at the lights. If you
want to know, see the small black spot in the
middle of the photos?

Yep, that's Mr. Busybody Policeman to you.
The moment you do it, he is the witness and
tells on you to his pals 100 metres away.
