I’ve been flashed.

Hello I was flashed on 11.07.09 in Baden-Württemberg outside of closed villages with 103kmh (after tolerance deduction). 70kmh were allowed. That means: 33kmh too fast. According to the fine catalog 3 points and 75.-Euro fine (plus processing fees). I only saw, however, that I was flashed from the beginning. Today came a letter from the fine office (Landratsamt), with a questionnaire to indicate who led the vehicle at the time of action. So, now my questions: Should I first of all from the A Should I have the proof photos shown? If only flashed from the front, am I also relevant? If I do not know who has driven, then I have to write 1 year travel book? Please write me your experiences I thank you, Gerry
