We all know that heavy trucks can't be used in race since they are way too big. If you are going to use that in a race then prepare to be jailed for maybe a lifetime since you surely are going to cause massive destruction on the road. Even if it is not intentional, the destruction that the truck could cause is something serious that no one can't deny. These trucks are hard to maneuver and when we talk about race, there is a lot of maneuvering in order to get ahead of everyone. Besides, who would want to watch that since people know that their lives are in great peril while watching such race live.
However, this is just a game, so we can do the impossible and get away with it without getting sued. Drive your truck as fast as you can till you reach the finish line. Grab the coins, fuel, turbo, magnet as you drive your truck. Each has its uses and you will definitely benefit from these things in this game. Of course, the most important thing of them all is the coins since you can use it to upgrade your truck after the race.
