"Ich kenne die Verkehrszeichen" is an Android app designed for driving students who are learning for their driver's license exam as well as for children and teenagers who want to ride their bicycles on the streets. The app contains a directory of traffic signs, which are divided into categories, and their descriptions.

The app allows you to refresh your knowledge of traffic signs. It also conducts a quiz on sign knowledge with categories of your choice, number of questions, and type of questions (matching sign to description or description to sign).

The quiz results are saved in a table, where you can check your performance and review each quiz you have taken. Questions about signs that you have answered incorrectly are saved, allowing you to review and repeat them easily.
