You must hold a full licence to be able to ride a bike or drive a car outside the UK.
If you ride on just a CBT, not only do you stand a chance of being nabbed (bearing in mind that many countries now share data base information) by the Gendarmes or the Police but you will also not have insurance cover.
As much as i know in Europa most or country’s you dont need licences for 50cc bikes as it gos for 125cc they are riden on full bike licence but as im talking here all info is about Estonia . I think it works the same way in most of Europa I hope that this will help you …
You cant use " Cant use " provisional signs on your motor out side of country of use as it wont tell nothing to other country’s police officers or other road users. Also provisional licence are not translatable between country’s.
When I did the car test in Ireland it covered a motorbike up to 150cc. How times have changed. That was 1989. No L - plates tho.
The car test had a one way system town, no roundabouts, no pedestrian or traffic lights, no Zebra crossings, anyone that walked in front of you was 50/50. Done in the middle of Feb at 13.45 so no tourists or school kids. Done a 3 point turn that had no kerbs so - so long as you didn’t get stuck in the mud - you were fine. Last test of the day so the Examiner was dying to go home. It was friggin’ hard to fail.
