You might not find someone willing to race using a truck because that is the most dangerous stunt that could ever take place if that is held. Not to mention that the people watching near could get in danger and that is something that anyone wants. That won't bring lots of people in the event and it would also get the organizer sue for that. Of course, no one would ever want that, but that is a possibility when it comes to race. Since, you are using a truck on the race, you could expect that an accident is likely to happen and worst than that since it is way bigger. A truck could not be handle like that of a truck the road can't handle them. Actually, a quick turn could be fatal for the driver and anyone near the place. There is too much risk at hand and an accident is likely to happen. A truck isn't meant to be use on racing. Whoever use it other than delivering goods sure would not just dumb, but also crazy. Whoever driving a truck should obey the traffic rules and should not even attempt to try a stunt since that would endanger the lives of people near him. However, in this game, all that is possible since there won't be anyone that is going to be hurt. The idea here is to win the race or just make it to the finish line. of course, you would get some cash reward depending on your position. There are fuel and cash on the road. The road is full of obstacles and you need to reach the finish line before everyone does. You can use the money to buy upgrades and pray that would help you in the next race. The game becomes more challenging as you make some progress.
