  • Based on 2025 BC commercial driver's licence manual
  • Updated for April 2025
Commercial driving is a popular career choice because it provides opportunities for great pay, freedom to travel, and interesting people to meet. However, you’ll need the proper credentials to get started. A British Columbia Class 1 driver’s licence will open up those opportunities even further because it allows you to operate a wide variety of commercial vehicles. Semi-truck trailers, buses, dump trucks, and taxis are some of the vehicles that the Class 1 driver’s licence permits you to operate. However, you’ll need a British Columbia Class 1 learner’s licence to begin your training before you can legally drive on public roads.

While you must meet multiple requirements for both the Class 1 learner’s permit and Class 1 driver’s licence, one of the most important is passing the ICBC Class 1 Knowledge Test. It is crucial for you to spend quality time learning the skills needed to meet this requirement. The official knowledge test requires you to answer 80% of the questions correctly for your licence to be issued. Our British Columbia ICBC Class 1 Practice Test is an excellent resource for developing an understanding of these skills. It contains 50 questions to assess your current skill level and advance you toward a comprehensive skill set to facilitate your success.

This Class 1 Driver’s Licence Practice Test strategically prepares you to meet the challenges of the official knowledge test with reliable and authoritative information. The practice test is based on the most recent British Columbia ICBC commercial driver’s manual and is up to date as of April 2025. You’ll receive interactive preparation that no other on-line resources provide. The practice test includes 50 questions to assess and increase your current knowledge level. If you get a question wrong, the practice test will provide a detailed explanation of the correct answer. This approach is superior to the study guide method, which is designed to help you memorize the answers to the questions. The practice test helps you make a connection between the question and the information that supports the correct answer. You will develop the skills needed to pass the official knowledge test on the first attempt, and the confidence to show them in your driving habits.

The Fraser Canyon Gold Rush laid the foundation for roadway infrastructure, and you can build exceptional driving skills with other ICBC Class 1 practice tests at https://tests.ca/british-columbia/.
