The app "I know the road signs" is intended for driving students who learn for the driving test, as well as for children and young people who want to ride a bike on the road. It contains a directory with traffic signs, which are divided into categories, and their description.

The app allows you to refresh your knowledge of road signs. It also carries out a quiz on knowledge of characters: with chosen by you categories (assigning characters to describe or descriptive signs assign) number of questions and types of questions.

The quiz results are stored in a table, where you can check your performance and can look through each already completed quiz. Questions about characters to which you answered incorrectly are saved, what you allow them easy to look through and repeat.
