This is possibly the simplest car game ever and one we have probably all played at one time or another. The simple rules make this a game that even very young children can take part in.
Age: 3+
Choose a marker such as 'the next roundabout', 5 minutes or a distance that you can track on your car's milometre.
Every player picks a colour of car.
The player who counts the most cars of their colour in the time allowed is the winner.
