What a Brazilian driver's license is and who needs one
A Brazilian driver's license, called a Carteira Nacional de Habilitação (CNH), is the official document that permits you to operate a motor vehicle in Brazil. It is issued by the Departamento Estadual de Trânsito (DETRAN), which is the traffic authority in each state. If you are a resident of Brazil or plan to drive there for an extended period, you will need a CNH to drive legally.
If you are a foreign visitor with a valid driver's license from your home country, you can drive in Brazil for up to six months using your original license plus an International Driving Permit (IDP). After six months, you must obtain a Brazilian CNH. If you are relocating to Brazil or have already established residency, you should begin the CNH process as soon as possible, since the testing and approval timeline can take several weeks.
Brazil recognizes driver's licenses from most countries, but your foreign license does not replace the CNH requirement once you become a resident. The CNH is also required to register a vehicle, purchase car insurance, and rent a vehicle from most rental companies.
Key Takeaways
- The CNH is issued by your state's DETRAN office, not a federal body, so requirements and fees vary by state.
- You must pass a written test on traffic laws, a practical driving test, and a medical examination before receiving your CNH.
- The entire process typically takes four to eight weeks from your first appointment to receiving your license in hand.
- Residents must obtain a CNH within six months of establishing residency; foreign visitors can drive on their home license for six months.
- Your CNH is valid for ten years if you are under 65 years old, and five years if you are 65 or older.
Documents you need to bring to DETRAN
Before you visit your state's DETRAN office, gather the following documents. Requirements can vary slightly by state, so contact your local DETRAN office or check their website to confirm what they require in your specific location.
Proof of identity: Your passport (if you are a foreign resident) or your Brazilian national ID card (RG). If you have a CPF (Cadastro de Pessoas Físicas, the Brazilian tax ID number), bring that as well. Proof of residency: A recent utility bill, rental agreement, or official letter from your employer showing your name and current address in Brazil. The document must be dated within the last three months. Medical certificate: A form completed by a licensed physician confirming you are physically and mentally fit to drive. This form is often provided by DETRAN or can be obtained from a private clinic. Proof of payment: A receipt showing you have paid the CNH process fee to your state's DETRAN. The fee varies by state but typically ranges from 100 to 200 Brazilian reais.
If you are renewing an expired CNH, bring your old license as well. If your name has changed since your last document was issued, bring a marriage certificate, divorce decree, or court order showing the name change.
The written test on Brazilian traffic laws
The written test, called the Prova Teórica, covers Brazilian traffic laws, road signs, vehicle safety, and driving rules. The test is administered by DETRAN and is offered in Portuguese. If you do not speak Portuguese fluently, you may request an interpreter or written translation, though availability depends on your state's DETRAN office.
The test consists of 30 multiple-choice questions. You must answer at least 21 questions correctly to pass (a score of 70 percent or higher). You have one hour to complete the test. If you fail, you can retake the test after seven days. Most people are allowed up to three attempts before they must restart the entire process.
Study materials are available through DETRAN websites and private driving schools. Many states offer free online practice tests on their DETRAN portal. Hiring a driving instructor or attending a driving school course can help you prepare, though it is not required. Driving schools typically charge between 1,500 and 3,000 reais for a full course that includes classroom instruction, study materials, and practice driving sessions.
The practical driving test and medical examination
After you pass the written test, you must schedule a Prova Prática, the practical driving test. This test is conducted by a DETRAN examiner and takes place on public roads in your city. The examiner will ask you to perform basic maneuvers such as parking, lane changes, and stopping. The test typically lasts 20 to 30 minutes. You must demonstrate safe driving habits and knowledge of traffic rules. If you fail, you can retake the test after 15 days.
You will also need to pass a medical examination before your CNH is issued. This exam includes a vision test, hearing test, and assessment of your physical and mental fitness to drive. The exam is performed by a physician approved by DETRAN. You can have the exam done at a public health clinic or a private clinic. The cost is usually between 50 and 150 reais. The medical certificate is valid for one year, so schedule your exam close to the time you plan to take your practical test.
For the practical test, you will need to provide a vehicle. Many people use a vehicle from a driving school, which is included in the school's course fee. If you use your own vehicle, it must be registered and insured. The vehicle must also pass a safety inspection before the test date.
Timeline and fees for obtaining your CNH
The entire process from your first DETRAN appointment to receiving your CNH in hand typically takes four to eight weeks. The timeline depends on how quickly you schedule appointments, how many attempts you need to pass the tests, and your state's processing speed.
| Step | Typical Timeline | Cost Range (Brazilian Reais) |
|---|---|---|
| Initial DETRAN appointment and process | 1 to 2 weeks to schedule | 100–200 |
| Medical examination | 1 to 2 weeks | 50–150 |
| Written test (Prova Teórica) | 1 to 3 weeks after process | Included in process fee |
| Practical test (Prova Prática) | 2 to 4 weeks after passing written test | Included in process fee |
| CNH issuance and delivery | 1 to 2 weeks after passing practical test | Included in process fee |
| Driving school course (optional) | 4 to 8 weeks | 1,500–3,000 |
The total cost for obtaining a CNH without a driving school is typically 150 to 350 reais. If you choose to attend a driving school, the total cost rises to approximately 1,650 to 3,350 reais. Fees and timelines vary by state, so contact your local DETRAN office for exact figures.
Renewing your CNH before it expires
Your CNH is valid for ten years if you are under 65 years old, and five years if you are 65 or older. You should begin the renewal process at least 30 days before your license expires. Renewal is faster than obtaining a new CNH for the first time: you do not need to retake the written or practical tests unless your license was suspended or you have accumulated serious traffic violations.
To renew, visit your state's DETRAN office with your expiring CNH, proof of residency, and a new medical certificate. You will pay a renewal fee, which is typically the same as the original process fee. The renewal process usually takes two to four weeks. If your license has been expired for more than two years, you may need to retake the written and practical tests, so do not delay renewal.
Some states allow you to renew your CNH online through their DETRAN portal if you have no traffic violations and your medical certificate is current. Check your state's DETRAN website to see if this option is available to you.
Different CNH categories and what you can drive
Brazil issues CNH licenses in different categories based on the type of vehicle you want to drive. Each category has different age requirements and training hours.
Category A: Motorcycles and mopeds. Minimum age is 18 years. Category B: Cars and light vehicles up to 3,500 kilograms. Minimum age is 18 years. This is the most common category for personal vehicle drivers. Category C: Trucks and vehicles between 3,500 and 6,000 kilograms. Minimum age is 18 years. Category D: Buses and vehicles carrying more than eight passengers. Minimum age is 24 years. Category E: Articulated trucks and vehicles towing trailers. Minimum age is 21 years and requires a Category C or D license first.
When you explore for your CNH, you specify which category or categories you want. You can hold multiple categories on the same license. The written and practical tests differ by category, so you will study and test separately for each one you pursue.
Frequently Asked Questions
Can I drive in Brazil on my home country's driver's license?
Yes, for up to six months if you are a visitor. You must carry your original license plus an International Driving Permit (IDP) issued by your home country. After six months, you must obtain a Brazilian CNH. If you are a resident, you should obtain a CNH as soon as possible rather than waiting for the six-month window to close.
What happens if I fail the written or practical test?
You can retake the written test after seven days and the practical test after 15 days. You are typically allowed three attempts at each test. If you fail all three times, you must restart the entire process from the beginning, including paying the process fee again.
Do I need to attend a driving school to get my CNH?
No, driving school is optional. However, many people find it helpful because instructors teach you the specific rules and procedures DETRAN examiners expect. You can study independently using DETRAN's free online materials and practice tests, then take the tests on your own.
How long does it take to get a CNH if I already have a valid license from another country?
The timeline is the same as for anyone else: four to eight weeks. Your foreign license does not exempt you from the written test, practical test, or medical examination. However, your driving experience may help you pass the practical test more easily.
What do I do if my CNH is lost or stolen?
Visit your state's DETRAN office and request a replacement. Bring your proof of identity and residency. You will pay a replacement fee, typically between 50 and 100 reais. The replacement CNH is usually issued within two to four weeks. If your license was stolen, you may also want to file a police report for your records.
