User Reviews

Reviews show the app provides substantial CDL study content and can help some users study and even pass. However, major downsides include its mismatch with real Iowa CDL tests, incomplete question coverage, frequent readability/formatting and loading issues, and recurring subscription/payments problems. Overall, it's a useful study aid but unreliable in practice.

Pros

Substantial CDL study content and practice questions.
Helpful for studying; some users report passing after using it.
Widely regarded by reviewers as a useful CDL study resource.

Cons

Inadequate alignment with the real CDL tests; limited and incomplete question coverage; many topics missing or outdated.
Readability/formatting issues causing questions and answers to be cut off or unreadable; fonts and layout problems across devices.
Frequent technical glitches and loading problems; not reliably mobile-friendly.
Subscription and payment problems (locked content after purchase, charges after cancellation) are common.

I have taken the CDL permit twice now and I have gotten air brakes, and combination all memorized, but when I go to the DOT to take it, it’s not even the same answer, or there was more questions that I’ve never seen before on the test, and not on the app. Look for other apps that have the correct questions that can actually help you, not this app.

The questions in pool of each subject don’t cover everything on the tests. So far I’ve taken introduction, driving safely, transporting cargo safely, transporting passenger safely, air brakes, and school bus. I’ve noticed in all of the tests, questions that are not in the study pools.

Studied for the CDL test using this app and maybe 10% of the questions were actually on the test. If you want to fail your CDL test the first time and waste $6.99 for a subscription that doesn’t help your studying, this is the app to use. Would highly recommend dmv-permit-test.com
