The pre-trip inspection is a required safety check you perform at the beginning of your shift, before driving a commercial vehicle. This inspection prevents accidents caused by damaged or improperly installed equipment and keeps you in compliance with FMCSA rules. As an aspiring commercial driver, you should study this procedure in detail and master every step. You will find more information on pre-trip inspections in the Wisconsin Commercial Driver’s Manual (Wisconsin CDL Handbook 2025), which is an official resource published by the Department of Transportation (DMV).

The official general knowledge exam consists of 50 multiple-choice questions. To get a Commercial Learner’s Permit (CLP), you must pass this exam with a score of 80% or higher. Your knowledge of pre-trip inspections, safe driving practices, hours of service regulations, and other safety requirements will be evaluated at the DMV location.

I did not even look at the DMV manual.
I followed the program and retook my incorrect questions. I got 100% on my haz mat test at the DMV. Amazing prep program! I would totally recommend this to anyone!

Got my cdl and tanker endorsement last year and wanted to.
I got my cdl and tanker endorsement last year and wanted to get my hazmat endorsement also but the school I went to charged 500 dollars for a day and a half for hazmat training I looked for other alternatives and found this website 100 dollars for 30 days and it definitely paid off it less than 15 mins if that to pass the test and get my hazmat endorsement I highly recommend this program.

I took hazmat and tanker finished both….
I took hazmat and tanker finished both in about 5 minutes with 100% on both. every question on both tests were in the practice test!

Love this testing platform.
I studied for 2 days and passed my cdl test with flying colors! Trustpilot even said I only had a 50% chance of passing my test. The tests helped a lot! I would recommend to anyone going it alone in this process.
MH
Passed on the first try.
I needed to upgrade my class A CDL to include a Tanker/Hazmat endorsement. I looked at a couple of other companies, but this was the most reasonable. The website was user friendly and I passed on my first try! I also was able to ask a couple of questions online and got responses and my questions answered. It was a good overall experience.
