Free Pennsylvania CDL HazMat Endorsement Practice Test 2025

  • Perfect for first-time and renewal CDL/CLP applicants, and those adding endorsements.

Driving through Pennsylvania’s unique terrain, you’ll experience the Allegheny and Appalachian Mountains, as well as the winding river valleys around the Susquehanna and Delaware rivers. Adding the Hazardous Materials (Hazmat) endorsement to your Commercial Driver’s License (CDL) is a fantastic way to expand your job opportunities, which may result in higher pay. If you’re interested, you’ve come to the right place!

A Hazmat endorsement authorizes drivers to safely transport materials classified hazardous by the U.S. government. In the Keystone State, these include gasoline, petroleum products, industrial gasses, flammable liquids and solids, and agricultural chemicals. Many prominent organizations in Pennsylvania rely on drivers with Hazmat certifications, including PPG Industries in Pittsburgh for chemical and coating manufacturing, Sunoco in Philadelphia for petroleum distribution, Air Products and Chemicals in Allentown for industrial gasses, BASF in Wyandotte for chemical manufacturing and distribution, and Westinghouse Electric in Cranberry Township for handling nuclear materials. That’s a lot of opportunities closed to drivers without the endorsement!

“Ok, so how do I add this endorsement?” Obtaining a Hazmat endorsement is a detailed process with two major steps to ensure drivers are properly trained to handle hazardous materials safely: The Transportation Security Administration (TSA) review and the DOT knowledge test. The process starts with mandatory fingerprinting and a background check conducted by the TSA, which can take several weeks to complete. During this time, you’ll want to study and practice for the DOT knowledge test. This test covers federal regulations, substance handling, packaging, quantity limits, and transport configurations for hazardous materials. With a score of 80% on Pennsylvania’s 30-question knowledge test, drivers can move closer to unlocking new opportunities (Pennsylvania CDL Handbook 2025).

Feeling overwhelmed? Don’t worry. Our Pennsylvania DOT Hazmat Endorsement practice tests focus only on the essential information needed. With content streamlined to resemble what you will face on the official DOT test, we also provide immediate feedback on each response so you can learn as you go instead of waiting for end-of-test corrections. Ready to kick off the process? Once you receive your TSA results and feel prepared from all the practice, you’ll visit the DOT with the necessary documents, pay the fees, pass the test, and start the next level of your career.

Makes it too easy to pass.
Easy to sign up for and access the Information and practice tests. All the questions on the practice tests were on the PA Hazmat\Tanker tests, passed first time with 0 wrong.
J
Best ELDT option.
I would highly recommend this online program for the Hazmat ELDT. Easy to use, cheaper than other options and is set up to ensure you pass the state test. Online test questions were identical to the dmv test. I used this for the Pennsylvania test.
CM
Excellent service.
I Joined this site because it was approved from the PA DMV as a provider to get my hazmat endorsement. The curse I took on here was excellent as it provided me with much information. I really likes how it explained each answer and gave you the opportunity to keep trying until completion. I highly recommend and will join again in future as a reference course Thank you.

Absolutely 💯%.
Absolutely 💯% you spend. I crammed for less than 24 hours and passed my PA CDL general knowledge as well as endorsements for Hazmat, Combination, Doubles/Triples, and Tank IN ONE TRY! The practice exams were tremendously thorough and matched nearly all the questions that I encountered on the actual exams. Don’t waste anymore time or money at the DMV then you absolutely must! Sign up for Driving-Tests and pass the first time!

This was the best program I ever used.
It helped me pass the test the first time i took it. The practice questions were exactly like the real test you take at DMV especially for your state. I was able to look at the exam and pull out key words that were on the exam simulator. I would recommend this course to anyone that is ready to take their hazmat test.
SA
ELDT course.
Needed to take a ELDT class for my Hazmat endorsement. The course was easy to understand. And helped me to retain information and pass the DPS test. It was cheaper than some of the other options. And the DPS office had no issue pulling up that I did the course.
MF
Excellent online ELDT training.
Very professional and appealing website interface for the user. Very fast support response and upload of certificates. Passed all three of my CDL written tests on first attempt: Passenger, Tanker and Hazmat.
GC
My overall experience with the program….
My overall experience with the program was awesome. I completed the ELDT+Hazmat in only 24hrs. I was also able to practice on the tanker endorsement as well. This program also taught me things that I didn’t know already. You can definitely complete the program in a day if you have already been studying. It’s also very easy to navigate.
