Simulado Detran is a free application that can be used to study for the driver's license exam. The program includes a large number of questions and answers, which are divided into different categories. The questions are presented in a random order so that the user can get a better idea of how the exam is structured.

Simulado Detran can also be used to study for the CNI test, which is used to obtain a driver's license in Brazil. The questions are divided into two categories: the ones that must be solved in the first try, and the ones that must be solved after a certain number of attempts.
