The great state of Washington can offer real economic opportunities to commercial drivers because of its rapidly growing and diverse economy.
Among key economic sectors in Washington requiring commercial drivers are aircraft manufacture, automotive manufacture, electronics, lumber and wood products, beverages, retail, agriculture, wine, and tourism. In addition, Washington receives a great deal of foreign cargo through its seaports. The Port of Seattle and the Port of Tacoma are two of the busiest seaports in the country. Truck drivers transport large volumes of all these cargoes. Note that seaports, like airports, are secure areas. You may need to obtain a Transport Workers Identification Credential (TWIC) card to pick up cargo at these seaports. Meanwhile, bus drivers transport tourists to destinations like the San Juan Islands, Olympic National Park, and Mount St. Helens.
Major commercial routes include Interstate 5 (heavily used by both trucks and buses), Interstate 82 (for transport of agricultural products from Yakima Valley), Interstate 90 (for cargo transport to logistics hubs), U.S. Route 97 (for agricultural and industrial freight to Oregon and British Columbia, Canada), and State Route 14 (for agricultural and industrial freight in southern Washington State).
Before you can obtain a Commercial Driver’s License (CDL), you must obtain a Commercial Learner’s Permit (CLP) so you can practice commercial driving under supervision. One important step toward obtaining a CLP is to pass the official General Knowledge test on commercial driving theory. You have probably been advised to read the official Washington Commercial Driver Guide (Washington CDL Handbook 2024)? We agree that you should read it because the official knowledge test is based on it. However, you’re probably here because you want to get some more help to pass the knowledge test than you’re getting by reading this commercial driving manual. If so, you’ve certainly come to the right place!
This free Washington CDL permit practice test, which you’re about to take, is based on the official state manual, just like the official knowledge test. It’s up to date as of December, 2024. There are 50 multiple-choice questions on such topics as basic driving techniques, cargo management, emergency preparedness, and pre-trip inspections. Unlike the official knowledge test, each question on this practice test comes with an available hint and an explanation of the correct answer. What this practice test doesn’t have is a time limit. Take your time and learn as much as you can from the experience.
Test-taking tip: On multiple-choice tests, some questions may contain at least one ridiculous or outlier answer choice intended to catch random guessers. Try to identify and eliminate any such answer choice(s) immediately. Then the correct answer must be among the remaining answer choices.
Perfect for
- First-time WA CDL and CLP applicants
- CDL holders adding endorsements
- WA CDL renewal applicants
