The conditions for upgrading: You must have held a B1 or B2 driver's license for more than 3 years (or an A1 license for more than 1 year), and you must not have accumulated 12 demerit points in any of the last three consecutive scoring cycles before applying. Situations where you cannot apply for an upgrade: You cannot apply for a Class A license upgrade under the following circumstances: being fully or primarily responsible for a fatal traffic accident; driving under the influence of alcohol; driving under the influence of alcohol during the current scoring cycle or any of the last three consecutive scoring cycles before applying; driving at speeds exceeding 50% of the speed limit during the current scoring cycle or any of the last three consecutive scoring cycles before applying.
