As of this Tuesday (12/9), the toxicology test will become compulsory for any person obtaining a National Driving License (CNH) for the first time for categories A (motorcycles) and B (passenger cars).
Until now, a negative test was only required for categories C, D and E, that is to say drivers of buses, minibuses, vans and school transport vehicles. Now the same exam rules apply to all CNH categories.
According to data from the National Road Traffic Secretariat (Senatran), the toxicological examination required to obtain a driving license is an examination with a wide detection window, aimed at verifying the consumption, active or not, of psychoactive substances up to 90 days before the procedure.
The test detects the following substances:
- Amphetamines (amphetamine, methamphetamine, MDA, MDMA, amfepramone and Fenproporex)
- Mazindol
- Cannabinoids (Marijuana and derivatives)
- Cocaine (Cocaine, Benzoylecgonine, Cocaethylene)
- Opiates (Morphine, Codeine, Heroin)
The substances detected are defined by Resolution No. 293 of the National Traffic Council (Contran).

How does this exam take place?
The wide detection window toxicological examination is carried out using a sample of keratin, which can be hair and/or fur. In the absence of these, it can be performed with the nails, but only upon presentation of a dermatological report confirming alopecia universalis. The aspiring driver can choose where the samples will be taken.

Why hair and nails?
Urine and blood tests have a detection window of only a few days. Hair strands, on the other hand, provide evidence of a prolonged and detailed history of drug use.
-
Where can I do the procedure?
Toxicological tests are carried out only by laboratories accredited by Senatran. These in turn rent laboratory sampling stations (PCL), which will be responsible for collecting the samples. Consult the list of qualified laboratories here.
-
How much does toxicology cost?
The Brazilian Highway Code (CTB) prohibits public entities from setting prices for scheduled examinations; prices are therefore defined by free competition.
-
Does it have an expiration date?
Yes, up to 90 days from the collection date and can be used for other purposes.
-
What should I do if I have consumed psychoactive substances as part of medical treatment?
Once the consumption of this type of substance is detected, it is necessary to prove the use following a medical prescription and in this way the right to authorization, renewal and change between categories is ensured.
-
Is it possible to request a rebuttal and administrative appeal?
Citizens are entitled to the right to counter-evidence and administrative appeal, which must be presented directly to the responsible laboratory. The control test is carried out with the original sample, instead of being carried out by another laboratory and/or a new biological sample. Typically, laboratories take two samples to guarantee the result.
Voting in Congress
During the discussion on the subject, the deputies estimated that the requirement for an exam would mean that whoever obtains their first permit will have to pay between R$110 and R$250 more in the process. The vote in favor of resuming mandatory testing in the bill was significant: 417 votes in the House and 72 in the Senate.
The law also allows physical and mental fitness clinics to serve as test collection points. The text also authorizes the use of resources collected through traffic fines to finance the training of low-income drivers (CNH Social).
