A monster truck is a massive truck that can make any driver shiver with fear at the sight of it. You won't find them on the road because they are hard to maneuver and it is mostly use in a derby. Most of the time, you can see them on the mountain because their big tires are made for that condition. However, that doesn't mean that they are free from accidents, so the driver of that vehicle must always remember some safety precautions to make sure that he can get to his destination safely. If you want to see some real monster truck then you need to go to the mountain and see it for your self. Some rich guys use these trucks for racing as they are the only ones that can afford those vehicles.
In this game, you don't need to be rich as you can drive one for yourself. Drive the truck as fast as you can till you reach the finish line. The game is a race to the finish line, so you need to drive fast or you will be left out. However, that doesn't mean that you shouldn't consider safety precautions as you can't get to the finish line once you crash. Remember to use the booster to get ahead of the other trucks ahead of you.
