About this app

The Detran (Brazilian DMV) theory test has 30 questions, lasts at least an hour, and you need 20 correct answers to pass. That's exactly the format that CNHSimulado trains you in.

And there's one thing we don't do: ads during the test. None. You start the simulation and go all the way to the end without interruption, without losing progress, without a timer running while a video plays.

🎯 WHAT YOU WILL FIND

▸ Real-Time Exam Mode in the official format: 30 questions, 60 minutes, no going back
▸ Commented correction: if you get it wrong, the app explains why the correct answer is correct and why yours was wrong
▸ Readiness Score from 0 to 100%, to know when you can schedule the exam
▸ Quiz of 122 traffic signs based on the Brazilian Traffic Signalling Manuals of CONTRAN/SENATRAN
▸ 35 articles on fines based on the Brazilian Traffic Code (Law 9.503/1997)
▸ Study separated by subject: legislation, defensive driving, first aid, mechanics and citizenship
▸ Personalized study plan based on your exam date
▸ Offline mode. Study from anywhere, without needing internet.

▸ Daily reminders at the time you choose

✅ ATTENTION: THE CUT-OFF SCORE HAS CHANGED

Many people still study thinking they need 21 correct answers. Since December 2025, it's 20. CONTRAN Resolution No. 1,020/2025, in article 34, states that the candidate needs to achieve a "minimum score of twenty correct answers," and article 140, item IV, revoked Resolution 789/2020, which was the 70% standard.

The same text, in article 33, paragraph 2, guarantees a minimum duration of one hour, doubled for candidates with dyslexia, ADHD, or ASD. Our Real Test Mode follows both.

🧠 THE APP LEARNS FROM YOUR MISTAKES

Instead of answering the same easy questions over and over again, the app uses spaced repetition: questions you get wrong or take too long to answer come back more often, with intervals calculated to truly solidify the information. You study less and learn faster.

📊 READINESS

A score from 0 to 100% that honestly shows if you are ready. Calculated from your last Real Tests, considering average correct answers, consistency, and coverage by category.

Don't schedule the test without checking your Readiness.
