Speeding in real life can get you in real trouble, but not in Nitro Haul - that's the objective - to get through the map as quickly as possible. Here's the kicker - you get to build your own vehicle from scratch. The toolbox is used to create wheels and the framework for each hauler you build. Every level is unique and will call for a different type of hauler each time. Once the hauler is completed, click 'generate' to release the beast and see how it works. Use the arrow keys to go forward and backward. Go ahead and start building.
