I have a British Learners licence and just wanted to know if i can go for driving lessons here in Polska and then later apply for a driver's licence.My polish is not that good so i don't think it would be easy for me to start from the beginning like reading the learners driving code.
You'll need to have the 5 year EU residence permit before sitting the test in order to fufil the 185 days legal residency rule.
Other than that, you're free to go - there's no provisional licence here, so you just go to a school, sign up for the 30 hours of theory classes in English, do the first aid course and get a medical check, then do the 30 hours of practical training, then the test is yours to sit. The theory test is available in English in some localities, and you'll need a sworn translator for the driving part of the test.
Just spotted that you're in Poznan - zdaj prawko .com is highly recommended and provides you with everything you need.
