I have recently made a huge mistake and drove my car in the Netherlands while I was over the legal drinking limit. They took my license from me but I need to drive home, will I be able to get onto the ferry in my car if I drive and if so will I be able to drive in the UK if I am banned in the Netherlands?
I do have a spare copy of my licence is this allowed to be used?
Edit: My licence is a UK license and the vehicle is registered in the UK so nothing is registered in the Netherlands.
Under Dutch law, your license was taken as part of a driving ban. This ban starts immediately, which means that there's no judicial decision taken yet.
The UK recognizes irlandês driving bans, specifically. Dutch driving bans do not apply. You can therefore request your license back from the Dutch "Openbaar Ministerie", as you need your license to legally drive in the UK.
As you figured out in the comments, chances are pretty high that you will need a driver to put your car on the ferry.
In the mean time, the legal process will continue. The Dutch courts will almost certainly not convict you before Brexit, so it's a guess whether that information will be shared with the UK.
