No sticker... just the fine I am afraid. I asked the police about this also and they said they dont need to put a sticker, if the policeman saw you then that is enough. Thats a bum system if you ask me.

I have also gotten speeding tickets while my car was in for service. I ended up paying these as well because when I went to the company to demand they pay they said I didnt sign the car over so it is no proof that I actually wasnt driving the car.
