Well according to the French automated speed cameras that twice caught me driving in excess of the actual permitted 83km per hour, I was travelling at 88km so guilty as charged. The signed speed is 80 but they allow 3 km discrepancy. Their notice of prosecution is interesting which allows, according to information on the sheet, 91 days before the summons becomes ineffective which I received over 100 days after the offence so could appeal. However if I wish to appeal I must send 65 euros instead of the 45 for paying straight away. Getting the money back if I won, becomes even more complicated with the possibility of my not fully understanding the appeal in the first place. I paid up quickly before Brexit could intervene. To make matters worse, I got clobbered twice during my four months travelling, I never saw the cameras but on the one time I did see a camera flash, they did not fine me.
