Same thing happened to a work colleague of mine from the UK. Except in his case it was not possible to swap the license as it must be done within the first 12 months of residency here in Switzerland. Cost him CHF 540 in fines and administration, plus mandatory driving lessons and having to take the driving test.I thought a foreign licence was only valid for the first six months of residency in a new country?
A friend of mine moved to The Netherlands and had been driving on an Irish licence for years. He happened to be asked for his licence at a police checkpoint one day on which he produced his Irish licence. They asked him how he’d been lining in the Netherlands and he said over three years. They informed him that he’d been driving illegally and with no insurance for over 2.5 years. They took his details and postponed prosecution for a few weeks, giving him time to get a valid license and insurance. He did this, brought it to the police station, so then shelved his prosecution.
Ignorance is no excuse!
