The world is such a peaceful place and monster trucks are the only monster on the road. The mere sight of it might bring shiver to the bone and that is why; it not commonly seen on the road. However, when the zombie apocalypse happened, no road is safe anymore, so they bring in the big guns, rather the big truck. Now, the truck driver won't avoid the road anymore because it is just filled with flesh-eating monsters. Monster trucks are just use for stunts, but ever since the crisis, it got a new use for its big wheels - it is use to crush the skull of those undead.
Drive the truck as fast as you can till you reach the finish line. Crush those vehicles on the road for some points. You will get an added points for those stars that you get. There won't be any zombies on the first level, but be prepared for them as you progress in the game. There won't be any time limit, so you can take as much time as you want. If you want those stars, you need to gather some momentum because those stars are placed in high places.
