Trukz

Trukz (pronounced Trucks) is the largest trucking simulation on the web. It is a persistent browser based game which allows you to play the role of an independent truck driver, driving cargo between cities across Europe and the United States.

Once you have signed up, you can buy your initial truck and equipment and start taking loads between cities straight away, earning in-game cash which will allow you to access new trucks and equipment. For more serious players looking at running a trucking company, players can create their own company or join one of the many hundreds of in-game companies, availing of exclusive discounts and in-game routes.

The game requires absolutely no downloads and is playable free in all supported browsers.
