However, they can be destroyed when they fall in the cliff or got crushed by the lowering draw bridge. Time is not the essence here as you can finished the game whenever you like. Unlike most truck, they aren’t going to be crash when they flip over. You can always get back on your feet and continue your journey to the finish line when you do.
