Forty percent of every category is free, with the explanations. Not a sample of one exam and a paywall on the rest.
One optional in-app purchase unlocks the full bank of 34,931 questions and removes all ads, for good. It restores on any device signed in to the same Google account. Ads never appear during a timed mock exam, paid or not.
Where the questions come from
Every item is original practice material written against current federal sources: the FMCSA CDL manual, 49 CFR for hazardous materials, and 40 CFR Part 82 for refrigerant handling. Nothing is copied from a real exam, and every numeric threshold is checked against the regulation text.
What we can and cannot promise
TradeCert is an independent study aid. It is not affiliated with, endorsed by, or sponsored by the FMCSA, the US EPA, any state licensing authority, or any testing organization, and passing a practice test does not guarantee passing the official exam. Always confirm current requirements with the issuing agency.
