View All PlansAnyone interested in driving combination vehicles must first obtain a Class A Commercial Driver’s License (CDL). This license is only granted after meeting eligibility requirements, passing several theory and skills tests, undergoing a vision screening and a medical examination, providing identification documents, and paying the licensing fees. Additionally, all aspiring commercial drivers must complete Entry-Level Driver Training (ELDT) during the licensing process. This is a federal requirement that applies to all 50 U.S. states, including Washington.
We will help you pass your theory exams by providing you with access to our practice tests. This particular Washington CDL Combination Vehicles Practice Test is one of several we offer. It consists of 25 multiple-choice questions based on the official Washington Commercial Driver Guide (Washington CDL Handbook 2025), specifically Section 6 (Combination Vehicles). You must score 80% or higher to pass.
As you begin your learning phase, it is perfectly normal to fail your first few attempts. If you are unfamiliar with commercial driving theory, we recommend reading the official Commercial Driver Guide first. You can also check out our Free Washington CDL Permit Practice Test to strengthen your knowledge of this subject. You have unlimited attempts to train as many times as you want. With perseverance and consistency, your knowledge will naturally increase over time.
Your personal Challenge Bank™ includes helpful insights and detailed explanations. All your missed questions are stored here so you can practice with them separately. We recommend visiting your personal Challenge Bank at the end of a study session to review your mistakes and understand what went wrong. Pay attention to the feedback provided and note it in a notebook or notebook app for future reference. Questions in your Challenge Bank will remain there until you answer them correctly. If you are a premium user, you can also add any question to your Challenge Bank by clicking the bookmark icon in the top-right corner of the page.
It takes time and effort to learn a new skill. Use our Washington CDL Combination Vehicles Practice Tests alongside the official Commercial Driver Guide to boost your learning potential and master this subject effectively.
