What are the two major types of vehicle components that require inspection before driving?

The correct answer highlights the importance of ensuring that both mechanical and operational components are in good working order before operating a vehicle. Mechanical components include essential elements such as the engine, transmission, brakes, and tires, which are critical for the vehicle's overall functionality and safety. These components must be thoroughly inspected to prevent mechanical failures that could lead to accidents or breakdowns.

Operational components refer to systems related to the way the vehicle operates, including lights, signals, and wipers. Proper functioning of these components is crucial for safe driving, as they ensure visibility and communication with other road users, especially in adverse conditions or at night.

While other types of components like aesthetic or comfort components may enhance the driving experience, they do not directly impact safety and functionality like mechanical and operational components do. Therefore, conducting inspections on these categories is vital for ensuring that a vehicle is safe to drive and compliant with regulations.
