Live the dream in Hawaii by earning the Hazardous Materials (HazMat) Endorsement (H) for your CDL and immediately boosting your career and income potential. This credential opens doors to higher-paying jobs and increased opportunities with major industries throughout the state, including energy companies, chemical distributors, and fuel transport services. Hazardous cargo in Hawaii includes propane, fuel oil, pesticides, fertilizers, and other regulated materials that are essential for life on the islands.

Because of the risks, the HazMat endorsement process focuses on safety and compliance. Federal and state regulations require you to demonstrate that hazardous materials are properly contained, clearly marked, and safely transported (the three cornerstones of hazardous material management). The first step toward achieving this endorsement is completing a federally mandated Transportation Security Administration (TSA) fingerprint-based background check. This process can take weeks, so use the waiting period to complete Entry-Level Driver Training (ELDT) requirements and study for the final big requirement: the HazMat Knowledge Test.

About the Hawaii CDL

The Hawaii HazMat knowledge test is based on Section 9 of the Hawaii CDL Manual. It covers federal rules, driver responsibilities, placarding, communication requirements, emergency procedures, and safe loading/unloading. The test is multiple-choice, and you must score at least 80% (24 correct answers out of 30) to pass.

Don’t let the multiple steps involved in this endorsement overwhelm you. Our online practice tests are based on the official Hawaii DMV CDL Manual, which is the primary resource for the official exam. Our practice tests give you instant feedback after each question, helping you learn as you go instead of waiting until the end. The format mirrors the real exam, so when test day comes, you’ll know exactly what to expect. And this practice test is just one of three in our Hawaii-specific suite of tests.

Once TSA clearance and ELDT training are successfully completed, and you feel prepared for the knowledge test, visit your county DMV with the required documents, pay the fees, and take the exam. Once you’ve passed, you will be a member of an elite group of CDL drivers certified to handle the most sensitive and valuable cargo on the road.

Whether you’re hauling fuel across Oahu, Maui, or the outer-island communities, HazMat-certified drivers are in great demand. Use our practice tests and get started today. And while you’re at it, explore our other Hawaii-specific CDL endorsement practice tests to stay ahead of the pack!
