What Is the ICBC Class 4 Licence?

A Class 4 driver's licence in British Columbia authorises you to operate vehicles carrying up to 24 passengers — including taxis, ride-share vehicles (Uber, Lyft), ambulances, special activity buses, and some work-crew buses. It is the required licence for anyone driving commercially for passenger transport in BC.

To apply for a Class 4 licence, you must already hold a valid, full (non-learner) Class 5 licence. The upgrade process involves passing both a Class 4 knowledge test and a Class 4 road test. This page focuses on the knowledge test component.

The Class 4 knowledge test builds directly on Class 5 content — all the road signs, traffic rules, speed limits, and safe driving practices you already know — and adds a significant layer of commercial passenger vehicle material. Topics unique to Class 4 include passenger safety, professional driver conduct, vehicle inspection procedures, hours-of-service regulations, and taxi and ride-share operating rules.

What Is on the Class 4 Knowledge Test?

Road Signs & Signals

All regulatory, warning, guide, and construction signs — same weighting as Class 5.

Passenger Safety

Loading, unloading, behaviour management, and duties to passengers.

Driver Conduct

Professionalism, personal conduct, and responsibilities as a commercial driver.

Vehicle Pre-Trip Inspection

Systematic inspection requirements before operating a commercial passenger vehicle.

Fatigue & Hours of Service

Federal and provincial rules around driving hours and mandatory rest periods.

Taxi & Ride-Share Regulations

Licensing, insurance, and operational rules for TNS (transportation network services).

Insurance & Liability

ICBC insurance requirements specific to Class 4 vehicles and operations.

Rules of the Road

Speed limits, intersections, parking, right-of-way — all Class 5 content applies.

How to Pass the Class 4 Knowledge Test

1

Download and read both ICBC manuals

The Driving Commercial Vehicles guide covers everything unique to Class 4. The Learn to Drive Smart manual covers the underlying Class 5 content. You need both. Focus on the sections covering passenger safety, vehicle inspection, and hours of service.

2

Practice with our knowledge test questions

Use the free practice questions on this site to test yourself on road signs, rules of the road, speed limits, and intersections — all topics that appear on the Class 4 test. The more questions you answer, the more familiar you become with the question format.

3

Take a timed mock exam

Our mock exam simulates the real test environment with a time limit and 50 questions. Taking mock exams before your real test reduces anxiety and helps you identify topics you need to review.

4

Focus on Class 4-specific material

Most people who fail the Class 4 test miss questions on passenger management, driver conduct, or pre-trip inspection — not the basic road rules. Pay extra attention to the commercial-specific chapters in the Driving Commercial Vehicles guide.

Class 4 Eligibility Reminder

You must hold a valid, full (non-learner, non-novice) Class 5 driver's licence before applying for a Class 4 upgrade. If you are still on your Class 7L or Class 7N, complete the Graduated Licensing Program first.
