NM CDL HazMat Practice Test 3 2025

New Mexico’s diverse terrain, from the deserts to the mountains and high plateaus, presents great opportunities for Commercial Driver’s License (CDL) drivers, particularly those with the Hazardous Materials (Hazmat) endorsement. Adding the HazMat endorsement to your CDL is an excellent way to add versatility and potentially increase your earnings. This endorsement permits drivers to transport materials that the U.S. government has deemed hazardous, which include explosives and certain types of fuel, industrial chemicals, radioactive materials, and infectious substances, just to name a few. With safety as the paramount purpose of the endorsement process, New Mexico’s HazMat endorsement process is more complex than those of other endorsements.

The minimum age for the Hazmat endorsement in the Land of Enchantment is 21. There are three major hurdles prior to receiving your endorsement. First, you must complete all Entry-Level Driver Training (ELDT) requirements. Second, you’ll need to pass a Transportation Security Administration (TSA) fingerprinting and background check. And the last major hurdle is passing the New Mexico MVD HazMat Knowledge Test. You’ll want to use a bit of scheduling strategy here. The TSA results usually take weeks to return, so submitting that paperwork now and using the wait time to study for the Knowledge Test is a smart move! The official knowledge test is made up of 30 questions and must be passed with a score of at least 80% (that means at least 24 correct answers) (New Mexico CDL Handbook 2025).

Hazardous materials include chemicals used in the oil and gas industry, explosives (due to mining and drilling operations), radioactive materials (due to proximity to nuclear facilities), gasoline, propane, and hazardous waste from industrial activities. Major organizations requiring this endorsement include HollyFrontier Refining (Albuquerque), ExxonMobil (Carlsbad), and Los Alamos National Laboratory (Los Alamos). This sounds pretty lucrative, right? Let’s look at how we’ve eased the process for you.
