Practice questions with answers

A sample of 10 questions from the Class 4 knowledge test bank, spread across its subjects and shown in full before you start.

Sample question 1Road signs
StopSTOP

You are carrying a paying passenger through a quiet Alberta intersection when you reach this sign. What must you do before continuing?

Correct answer: Stop completely, yield to traffic and pedestrians, then proceed when safe

You must stop completely, yield to traffic and pedestrians, and move only when the intersection is safe. A full stop gives you time to see road users who may enter your path, even when the street looks quiet. Slowing without stopping is not enough, and your passenger's schedule does not change the duty to yield.

Sample question 2Rules of the road

Your paying passenger is belted in, and you are ready to pull your taxi away from the curb into moving traffic.

Correct answer: Signal, check your mirror and over your shoulder, then wait for a gap you do not have to force

You must signal, check the mirror and blind spot over your shoulder, then wait for a safe gap before leaving the curb. This lets you find cyclists and vehicles beside the taxi and keeps moving traffic from braking or swerving to avoid you. A signal shows your intention, but it does not require another driver to yield.

Sample question 3Rules of the road

A paying passenger asks you to turn at the next intersection, but your taxi is in a through lane. What should you do?

Correct answer: Continue straight, then use a safe legal route to return to the destination

A passenger's request does not make a last-minute lane change safe or legal. Swerving or cutting across a turn lane can surprise nearby drivers and place the passenger and other road users at risk. Continue straight, then choose the next safe legal route that brings the passenger back toward the destination.

Sample question 4Rules of the road

Your taxi has a full load of paying passengers and luggage on a wet road, with another vehicle ahead. How should you follow?

Correct answer: Leave more space than you would need with an empty taxi

On a wet road with passengers and luggage aboard, leave more space than you would need in an empty taxi. The extra weight lengthens the stopping distance, while water reduces the grip available when you brake or steer. Keeping your usual gap or moving closer ignores both conditions, even if traffic ahead appears steady.

Sample question 5Rules of the road

You are dropping off a paying passenger, but the only stopping gap is beyond a painted bike lane from the curb. What should you do?

Correct answer: Find a legal stop where the taxi and an opening door do not cross the bike lane

Choose a legal stop where the taxi can reach the curb without occupying the bike lane or opening a door across it. Blocking that lane or swinging a door through it can force a cyclist suddenly into the path of faster traffic. A quick drop off does not make the bike lane a safe stopping place or transfer your sightline responsibility to the passenger.

Sample question 6Rules of the road

An exhausted paying passenger asks you to end the taxi trip beside an isolated roadway, well short of the address they booked. What should you do?

Correct answer: Continue to a safe place that completes the passenger's delivery

Your duty of care continues until the passenger has been delivered safely, not merely until the taxi has stopped moving. An exhausted or impaired person left beside an isolated road may wander into traffic, become stranded, or face danger from passing vehicles. A passenger's request to get out does not make an unsafe roadside location a safe end to the trip.

Sample question 7Rules of the road

Late in a long taxi shift with a paying passenger aboard, you cannot remember driving the last few blocks. What should you do?

Correct answer: Stop driving safely and arrange proper rest before carrying anyone again

A gap in your memory of recent driving means fatigue has already taken over your attention, so you must stop driving and rest properly. Fatigue can hide hazards and slow your response before you feel yourself falling asleep. Coffee, open windows, louder music, and extra effort may make you feel briefly alert, but they do not restore safe attention.

Sample question 8Rules of the road

A friend suggests you could drive their small airport shuttle bus on your full Class 5 licence alone, since it is not a taxi. Which vehicles actually require a Class 4 licence?

Correct answer: A taxi, an ambulance, or a bus seating fewer than 25 people including the driver

A Class 4 licence covers a taxi, an ambulance, or a bus seating fewer than 25 people including the driver, so a small shuttle bus falls under it even though it is not a taxi. It also carries everything a full Class 5 allows, so nothing you can already drive is taken away. Reading Class 4 as taxi only, or stretching it to every bus regardless of size, both miss the group it names.

Sample question 9Rules of the road

Your taxi engine fails with paying passengers aboard, and you coast onto the shoulder of a busy highway. What should you do next?

Correct answer: Move as far off the road as possible, use hazard lights, and have everyone exit away from traffic

Get the taxi as far off the road as you safely can, turn on the hazard lights, and move everyone out on the side away from traffic, behind a barrier when available. This reduces the chance that a passing vehicle will strike the disabled taxi or people standing near it. Keeping passengers inside or beside the taxi leaves them exposed to a secondary collision.

Alberta Driver's Guide (Government of Alberta)
Sample question 10Rules of the road

You arrive for a night pickup on an unlit residential road with no sidewalk, and your paying passenger is waiting opposite. Where should you stop?

Correct answer: Where the taxi lights and hazard lights make it visible from behind, so the passenger reaches the curb side door

At an unlit pickup, stop at the passenger's curb where your vehicle lights and hazard lights make the taxi visible to traffic approaching from behind. This gives following drivers warning while letting the passenger enter from the safer curb side. Waiting in the travel lane or making the passenger cross the dark road exposes both of you to traffic that may see you too late.
