A foreigner residing in Poland for more than 185 days must exchange their national driver's license for a Polish one.
When applying for a replacement driver's license, a valid license is not withdrawn - it can be used while the application is being processed. The processing time is 2-3 months. The foreigner receives notification of the day and time of the visit to the city administration to obtain a Polish driver's license. The previous license shall be withdrawn.
Citizens of Ukraine and other CIS countries, replacing the national license to Polish, do not pass the theoretical and practical exams.
If you do not replace your license on time, there is a very high probability of problems with the insurance company if an accident occurs. The insurance company will take advantage of the fact that the driver's license has not been changed and as a result, they can simply refuse to pay the insurance, under the pretext that by law the foreigner had no right to operate a vehicle in Poland.
