I was wondering, at first I know I need to have my full driving license over 3 years on which day does it start? From the day you pass it or the day you received the pink card? Can I start supervising someone few days before the full license reach its 3 years of date (lets assume I passed the test on the 26/01/08, can I start supervising from the beginning of the month like on the 1/01/11). Please let me know. Thanks
