That is certainly worthy of this thread. If you were clocked with more than 20 km/h over the posted speed limit it is considered as a serious traffic law violation (Grobeb Verkehrsregelverletzung).

As explained in the very first post of this thread there are two separate procedures which will run in parallel: The criminal process and the administrative process.

The incident from 2015 should have no impact regarding administrative measures (warning/driving ban). With 20 km/h over inside the urban/build area you have to face a 3 month ban.

The case from 5 years ago might have a slight impact on the criminal procedure. Means the fine or monetary penalty could be a bit higher than it would be for a first time offender. In case of 20 km/h over inside the ban/build area you have to face a monetary penalty of 20 - 30 days. It will be most likely on probation only. In addition you will have to pay a fine of around CHF 600 plus the court fees. For more details read the first few post of this thread.

Apart from the autobahn there are, as far as I am aware no 80 or 70 km/h stretches inside the build up area (Save some short stretches just before or after the city limit sign). If in doubt assume it is 60 km/h at most. In case of Zurich even those are pretty rare (Bernstrasse Nord and Süd or the short stretch of Allmendstrasse come to my mind).

I must admit, been in Switzerland for 10 years and never managed to get to 130 leave alone 170 on highways. Very brave and a bit silly. Because you not only endanger yourself but also others on the road. Please drive carefully......

Good grief. What are you driving, a milk float?

Agreed, driving so slowly on the motorway is a risk for others.

I have a follow up question. Assuming, I was really so above the speed (I haven't received yet the fine), 2 fines within 10 years is a lot I assume. There are 2 registry the public and the one only visible to judges and immigration office. I just received the new Strafregisterauszug which was immaculate (the thing of 5-6 years ago was not shown), but the judges will probably see both. Am I risking, to not have renewed my visa if something else happen? Or the three strikes rule apply only for the request to becoming Swiss.

A milk float sounds fun..... :-)
On a more serious note, when the speed limit is 120 kmph, anything more than 125 is asking for a fine or something more serious. Why not just follow the rules?

Update on my adventure!
In october I finally received the ticket of 570 CHF

last friday I received the notification of a 1 month suspension of my driving license. They were definitely holding it back for xmas!

Oh well, that hopefully concludes it. Lesson learned? Don't miss an end of semi-highway sign

Expect a bill for your license suspension.

Merry Christmas.

hold on,
today I passed by the road after Escherwyss and I realized it was with limit 30 when its very large (you can easily mistake it for a 50km/h road), according to the info if you speed over 31 in a 30km/h area, you go to jail... i dont think it s that difficult in this case. Any experience of people really ending up to jail? Can you defend yourself somehow and pay fines svoiding jail?

My The jail sentence will almost always be suspended for first-time serious offenders, which means no jail unless you commit a serious infraction again during the prescribed suspension or probationary period.

If you receive a suspended jail sentence, you will almost certainly have your driving licence suspended for a lengthy period, too. This could be a blessing in disguise, as (unless you are very stupid) it should remove the possibility of you re-offending during the probationary period and being sent to jail.

You can't pay fines to avoid jail. In fact, offenders who are sentenced to a suspended jail sentence have to pay a fine anyway, on top of the Sword of Damocles hanging over their heads for 2+ years.

absolutely true, i fully acknowledge that. my only excuse is that, as i wrote, the roads were deserted - there was absolutely no one in sight due to the lockdown and i got carried away. still, as the judge ruled, that's not a valid excuse i haven't been driving more than 120 km/h ever since (i did my three months ban already).

except in germany. which is very close to me as i'm in basel and the stretch to freiburg has no limits. strange how perspective can change quickly... makes you wonder who has the right rules...

A two years driving ban Art. 16c Abs. 2 lit a_bis SVG

So, it came today.
It is 24km/h over the limit of 50 km/h area, damn if I was not overtaking I would have been for sure under.

From the first link post. I gather that for violation below 25km/h (swoosh) it is 600 CHF and not counted on days of salary + Court cost will b 430 (1030 CHF).
I guess it is up to the police then about the warning or one month ban (I am prepared for both). Am I right?
