Questions people ask about this test

Can I take the ICBC knowledge test online?

Yes. Since June 9, 2026, ICBC lets you take the passenger vehicle (class 5 and 7) and motorcycle (class 6 and 8) knowledge tests online, on a computer with a webcam. You have up to 72 hours after registering to start, and 45 minutes to finish in a single session, and the $15 test fee is paid online. Passing does not hand you the licence: you still visit a driver licensing office, where you pay the licence fee separately.

How many questions are on the ICBC knowledge test?

Fifty, and you get 45 minutes to work through them. The timer is generous for the number of questions, so most people run out of certainty long before they run out of time.

Ten. You need 40 correct out of 50 to pass, so the eleventh wrong answer ends the attempt as a fail.

How soon can I retake the knowledge test if I fail?

After 7 days. ICBC holds you to that gap between attempts, so the same afternoon or the next morning is not an option.
