WA CDL General Knowledge Exam Simulator 2025

5 min

Before obtaining a Commercial Learner’s Permit (CLP) in Washington, all aspiring commercial drivers must pay the license fees, pass a vision test, undergo a medical exam, provide the necessary documentation, and pass a 50-question CDL General Knowledge exam. All questions are based on the official Washington commercial driver guide (Washington CDL Handbook 2025), which you should read at least once. It contains important information on the various aspects of commercial driving theory, including pre-trip inspections, safe driving practices, air brakes, and transportation of hazardous materials. After holding a CLP for 14 days and completing Entry-Level Driver Training (ELDT) from a registered training provider, you can take the CDL skills test.

The most determined students prefer to adopt a smarter approach and seek alternatives to traditional learning methods. When you enable active learning, any subject becomes easier to study as you naturally improve your knowledge with practice. Our Washington CDL General Knowledge Exam Simulator helps you familiarize yourself with the content and format of the official exam. You must answer 50 multiple-choice questions and score 80% or higher to pass, but there is no time limit to complete the test. You will not receive any assistance during your training sessions, and we also recommend avoiding external help. The purpose of our simulator is to help you evaluate your knowledge and identify areas that need improvement. Although you won’t receive any explanations for the questions you get wrong, you can get useful insight from your personal Challenge Bank™. This section includes detailed explanations for all the questions you got wrong during your previous sessions.

Started on Wednesday afternoon @ 4:12pm and aced all tests.
Aced my Class A CDL General Knowledge, Airbrakes, Combination, and Double &Triples tests @ 2:05pm on Thursday! I never even cracked the book, and I've never had a CDL before. The tests at the Washington State DOL were almost verbatim with the driving-tests.org ones!

Awesome product.
Awesome product and was just what I needed to pass all 3 CDL exams on the first time. Use it as directed and it works.

All I can say is..
WOW! I felt Very prepared for my CDL tests. I love the explanations given if you get a question wrong. I also Love the test bank of missed questions. I passed ALL 5 tests in 1 day! A couple of things that would greatly improve the program is 1. After the explanation, provide where it can be found, based on the states testing guide. 2. Having a broader base of questions. Some seemed to repeat themselves. 3. Providing a supplement for chapter 11 (pre inspection) as far as pictures for each of the 7 parts, with labels and testing that also has labeling.

All the questions on Driving-Test.Org are very useful..
From the time I decided to acquire my CDL Class A, it was the only source I consulted and studied. I tested for General Knowledge, Combination Vehicles, Air Brakes, and Doubles and Triples and passed all at one time. Secondly, it took me just 1 day to study and pass my HAMZAT. This website is really excellent and I recommend them to everyone Stanley

Give them a try! A decision you won't regret.
I had a great experience, straight forward and easy to understand content. I studied the course for Hazmat, Tankers, Doubles and Triples and while I aced both Hazmat and Tankers with a 100%, the questions I missed in my actual test for doubles and triples was because I didn't stop to analyze the questions before submitting my answers. Don't do like me and sleep on it, this is a decision you won't regret.
