When upgrading your driver's licence to a Class 3, there must be ______ weeks of authorized instruction prior to taking your road test.

Answer: A — two

When upgrading your driver's licence to a Class 3, there must be two weeks of authorized instruction prior to taking your road test. This means that you must have received two weeks of instruction from an authorized driving instructor before you can take your road test. The other options, three, one, and four, are incorrect because they do not meet the minimum requirement of two weeks. Selecting B as the answer would result in needing an additional week of instruction, selecting C would not meet the required amount of instruction time, and selecting D would provide too much time before taking the road test. Therefore, two weeks is the correct amount of time for authorized instruction before taking the road test for a Class 3 driver's licence.
