It contains 30 multiple-choice questions on a variety of topics in commercial driving: air brakes, hazardous materials, buses, combination vehicles, and tanker trucks.

Each practice question includes a picture and has four possible answers. Choose the most complete and correct answer for each question. Each question also comes with an optional hint if you need it and an explanation of the correct answer. Try our CDL diagnostic test and see whether you are ready for the real thing. Good luck, and drive safely!

Program was the best
I may not be the sharpest tool in the shed but I was able to pass my hazmat without missing a single question i surprised myself this program is great and recommend 100%

Quick and easy prep for the knowledge test at DMV.
Took the class the day before I took the knowledge test at the DMV. Got 100% on the test. Probably spent 3 hours on the "Theory" class and 3 hours on practice tests. Most of the questions at the DMV were on practice tests. The ones that weren't I just skipped because once you get 24 questions right you pass and don't have to answer the ones you skipped.

Your program is set up very well.
I nearly aced the three part CDL test. Thank you so much. Not bad for a seventy year old. Who says you can't teach old dogs new tricks:-)! PS- Before I started studying for the CDL I knew nothing about big rig trucks or truck mechanics in general. I will be taking a driving course starting next week in Reno Nevada. Thanks Again

I Passed 5 CDL Tests On The First Try!
I can't begin to tell you how much I appreciate driving-tests.org. I read the NV CDL handbook and never thought I could pass even the basic tests to get my CDL. Then I started using your service. I practiced until I was confident. I like being able to track my probability of passing. When I hit 100% I took the General, Combination, Air Brakes, Tankers, and Doubles/Triples. I breezed through every one of them. Not bad for a 62-year-old guy!

Quick and Easy Hazmat test preparation.
This ELDT Hazmat Theory training was very quick and simple. It adequately prepayment to take the exam at the DMV. I passed on my first try because I knew the answers from taking all the tests on this site. Would recommend to anyone needing ELDT for CDL endorsements.

5 out of 5.
This site was very helpful. I took all the tests and marathons. Multiple times. I missed very few questions on the exam, and 99% of the questions seem like they came from these tests. If I hadn't of studied here I would have been dreadfully under-prepared. I would recommend this to anyone who's thinking about getting their CDL.
