For cars to count as runs they must be moving and traveling in the opposite direction.

One person at a time comes up to 'bat', and they score 'runs' when vehicles are sighted. You can download a free car cricket scoring sheet with the basic rules, or another blank one so you can use your own variation. You may want to make a score limit so players have to retire if they make 100 runs or so. There are no universal rules, and there are many scoring variations based on different color cars and vehicle sizes.

It works best on less busy country roads. Runs are based on the color of the cars you pass, with a red car getting you out. It is only somewhat related to the real game of cricket - generally scoring is faster and much more exciting than the real game. Car Cricket is a fun way to keep the kids occupied on a long car trip.
