Use the arrow keys to drive.
The Towing Mission is a free flash parking game basically, but you also have the chance to tow cars that are blocking the traffic. In this city the other drivers are not really careful how they drive so to prevent accidents your mission is to get the cars left in the middle of the traffic and relocate them to a safer spot. Some of the cars are simply on some other people's parking spot so again you need to pick them up and move them to another spot. Have fun!
