I have tried more then once to pass this misson and i have had no success can some one please help?
If this is about the mission in GTA San Andreas, then it's pretty easy. You get into the monster truck( you spawn inches away from it after the cutscene) and drive through the checkpoints. Try going in a straight line from one checkpoint to another and try to not drive too fast. You have 6 minutes to finish the track, and beleive me, it can be done in 3 minutes without even reaching 3/4 of the truck's maximum speed. If a hill seems too steep to climb, don't worry, the truck is 4x4 so go for it!
