Fiscalização DENATRAN is a free mobile application developed by SERPRO for Android users. The app is specifically designed for traffic inspectors and is not intended for citizens or drivers. The app allows access to information related to traffic inspections, such as vehicle and driver registration, fines, and other relevant data.

To access the app's features, traffic inspectors must first register on the Denatran Services Portal and provide their device's ID code, along with their personal information. The user must also have a valid Gov.BR account. The app allows up to five daily queries for citizens and unlimited queries for traffic inspectors.

The app recommends that traffic inspectors log out of the app when they finish their work or share their devices with other inspectors. This is to prevent unauthorized access to the app. Overall, Fiscalização DENATRAN is a useful app for traffic inspectors who need quick access to information related to traffic inspections.
