4 Ways To Prepare For The CDL Practice Test General Knowledge

CDL General KnowledgePassing the written CDL General Knowledge is the first step towards obtaining a commercial driver’s license. You’ll need to prove your knowledge of commercial vehicles such as trucks and tractor trailers before the government will authorize you to drive one. Here’s how to prepare for success.

Study in Advance

Waiting to hit the books until the night before your written exam won’t help you. For the best chance at passing, begin studying the handbook well in advance. You’ll need to understand the special regulations and driving skills that apply to commercial vehicles when you get behind the wheel. That means last-minute won’t help– you won’t retain the information for when you need it. Give yourself a few weeks to study the handbook inside and out.


Take practice tests to make sure you’re retaining what you study. Assume that anything in the commercial driver’s license handbook could show up on the test. Try taking several practice tests before exam day to make sure you’ve covered all the material thoroughly. Still nervous? Have a friend take the handbook and administer a pop quiz.

Pack Your Bag

Before you can take the written exam, you’ll need to submit proof of identity and pay an exam fee. Forget those items and you’ll end up disappointed on test day! Acceptable ID may include a passport, Canadian citizenship card, work permit, permanent resident card, or photo card. Check with your province’s government for the full list.

Rest and Fuel

Once you’ve studied, the best way to prepare for your written exam is to sleep, eat, and drink well. Try to sleep well the night before the exam. Eat a healthy breakfast that won’t leave you feeling bloated or sleepy while you’re trying to concentrate on the test questions, and drink plenty of water to stave off a headache or dehydration. Just before the test, take deep breaths and try to clear your mind of any lingering anxieties. Trust that you’ve done everything you can to do your best.
