Passa CNH: Tests and Signs

Passa CNH is an independent study app for Brazil's CNH driving theory exam. It is not affiliated with any Detran, nor with CONTRAN, Senatran or any other government body. The sources of all its content are listed at the end of this description. The app is entirely in Brazilian Portuguese and follows the 2026 exam format: 30 questions covering 4 content blocks, with 20 correct answers needed to pass. It includes a 30-question practice exam with 60 minutes on the clock, practice by block with a law-referenced explanation for every question, 44 short lessons, 167 traffic signs, a queue that brings back the questions you miss, and a block-by-block view of your progress. It works offline. CONTENT SOURCES Everything the app teaches comes from laws, resolutions and manuals published by Brazil's federal government: • Brazilian Traffic Code (Lei nº 9.503/1997): https://www.lexml.gov.br/urn/urn:lex:br:federal:lei:1997-09-23;9503 • Lei nº 15.153/2025, on the drug test: https://www.lexml.gov.br/urn/urn:lex:br:federal:lei:2025-06-26;15153 • CONTRAN Resolution nº 1.020/2025, with the theory exam rules (30 questions, 20 correct answers, at least one hour): https://www.gov.br/transportes/pt-br/assuntos/transito/conteudo-contran/resolucoes/Resolucao10202025.pdf • Senatran Ordinance nº 923/2025, with the 4 content blocks: https://www.gov.br/transportes/pt-br/assuntos/transito/arquivos-senatran/portarias/2025/Portaria9232025.pdf • Brazilian Traffic Signage Manual (MBST), by CONTRAN: https://www.gov.br/transportes/pt-br/assuntos/transito/senatran/manuais-brasileiros-de-sinalizacao-de-transito • Other CONTRAN resolutions cited in the explanations: https://www.gov.br/transportes/pt-br/assuntos/transito/conteudo-Senatran/resolucoes-contran

• All 44 lessons were rewritten, with the rules checked again against the law. • The traffic-officer lesson follows the law in force: the hand-signal and whistle table is gone, as the resolution that defined it was revoked. • Questions on vehicle impoundment were corrected: that penalty left the traffic code in 2016. • Toxicology exam: a licence holder adding category A or B does not need it. • No terms screen at first launch. On iPhone, a short note about usage statistics appears once.
