Carteira Nacional De Habilitacao
In short
The Carteira Nacional de Habilitação (CNH) is the official driving licence issued by the Brazilian government to authorise vehicle operation.
In plain words
It is a legal document that proves you are trained and allowed to drive. It contains your personal details, photo, and the types of vehicles you can operate.
A simple example
A driver shows their digital or physical CNH to a police officer during a roadside check to prove they are licensed.
Why it matters
Without this document, driving is illegal and can lead to heavy fines or vehicle impoundment. It also serves as a vital form of personal identification.
Easy to mix up
It is often confused with a standard national ID card, though the CNH specifically focuses on driving privileges.
