Alberta Class 4 knowledge test: your missed questions
Everything this run does, in front of you first. Licensing in Alberta is run by Government of Alberta, and every line marked with a source below comes from what they publish.
How long this run is depends on how many questions this browser has saved from your earlier runs. The count appears with the button below once the page has read it.

- Thirty multiple choice questions, and 25 correct to pass, the same shape as every other Alberta knowledge test.
- Class 4 covers a taxi, an ambulance or a bus seating fewer than 25 people including the driver, and it carries everything a Class 5 allows.
- You need a full Class 5 licence and you have to be at least 18. Alberta does not say how long the Class 5 must have been held.
- A completed driver medical report form is required for Class 4, and a registry agent checks your vision at the counter.
- There is no road test. Alberta lists the road test step for Class 1, 2 and 3 only, so for Class 4 the knowledge test is the test.
- Ride hailing work needs this licence too. The Alberta ride for hire services page says a Class 5 is not enough and asks for a police information check.
- You can sit it once a day, and you pay for it every time.
- An oral assisted test, where a registry agent employee reads the questions out loud, is offered for Class 4.
- The air brake Q endorsement is a knowledge test of its own if the vehicle has air brakes.
