You have 50 cards with traffic signs and 50 cards with their explanation (in Dutch, French, Italian and German). And you have 8 cards with a police-man on it. Different ways of playing. Somebody reads the card, the others try to find the matching sign as quick as possible. Or you can deal the cards with signs. Somebody reads the cards aloud. You put the matching sign on it. If you're incorrect, you get a police-card.
