Speed fine

Hi folks!

Question: the 1st fine for overspeeding on a route where limit is 70km/h, I was having corrected speed of 92 km/h. Now, they sent me the proces-verbal and asking if I am willing to go for a transaction.

There was such a case before on this forum, but the OP did not indicate if there was a happy ending :).

What I would appreciate to know from your experience: if it the first time :) and then, of course I am willing to go for a transaction...meaning a fee and case closed. But who could tell me how much the fine will be?

Many thanks!!
