What is the primary danger of driving a motor grader (motoniveladora) on a public road with its moldboard blade (cuchilla) extended out past the tire width?

1. The blade will shave the asphalt unnecessarily
2. The extended heavy steel blade creates an extreme hazard that can strike oncoming vehicles, pedestrians, or road fixtures with catastrophic slicing impact; the blade must be angled, centered within vehicle width, and elevated for road travel
3. The fuel tank will overflow
4. The blade will make the grader turn into an airplane
