- Perfect for first-time and renewal CDL/CLP applicants, and those adding endorsements
- Based on 2025 WA commercial driver's license manual
- Triple-checked for accuracy
- Updated for August 2025
Washington State Apples, the Space Needle, Pike’s Place, and the coffee culture, added to Washington’s diverse landscape, and you’ll find lots to enjoy as you drive through the state. Since you’re here, you must be interested in the opportunities available once you’ve added the Hazardous Materials (Hazmat) endorsement to your Commercial Driver’s License (CDL). For 18–20-year-olds, Washington allows you to obtain a CDL and drive within state lines; however, you cannot obtain the hazmat endorsement until you reach the age of 21 per federal law. For those 21 and older, let’s take a look at this endorsement.
The U.S. government has labeled certain materials as hazardous and the Hazmat endorsement permits drivers to transport these items. They range from explosives to certain types of fuel, industrial chemicals, radioactive materials, and infectious substances. “Yikes! What am I getting myself into?!” Don’t worry. The most important objective of this endorsement process is to ensure your safety and protect the people and environment in your driving area.
To add this endorsement, you’ll need to pass a Transportation Security Administration (TSA) fingerprinting and background check. Taking care of that requirement is step one. While you wait for these results, you can tackle the second requirement: the DOL knowledge test. The knowledge test includes topics like federal regulations, substance handling, material packaging, quantity limits, and transport configurations for hazardous materials. You’ll have to score 80% or higher. You’ll need 24 of them answered correctly (Washington CDL Handbook 2025).
In the Evergreen State, there are multiple industries requiring a Hazmat endorsement. They include petroleum and fuel distribution (Shell and BP America have distribution facilities in the state), chemical manufacturing (Univar Solutions is headquartered in Belleview), agricultural chemicals (Wilbur-Elis and Helena Agri-Enterprises), waste management and environmental sciences (Clean Harbors and Stericycle), and industrial gas suppliers like Airgas and Praxair. What a list! The good news is we have simplified the process.
Our online Washington CDL HazMat Endorsement practice tests are designed to focus on what’s truly relevant instead of the mountain of information you’ll find online and mimic what you will face on the official DOL test. Don’t delay. Get your TSA requirements submitted and practice with our tests until they arrive. Then, go to the DOL with the necessary documents, pay the fees, and confidently pass the test.
