What items are typically not included in the safety inspection?

The correct choice highlights that comfort features, such as seat adjustments or air conditioning, are not typically included in a safety inspection. Safety inspections focus primarily on the components and systems directly related to the safe operation of the vehicle. This ensures that everything is functioning correctly to prevent accidents and ensure the safety of the driver and passengers.

In contrast, safety inspections will always include critical safety components like the brake system functionality, which is vital for stopping the vehicle safely. Similarly, the examination of tire tread depth is crucial because sufficient tread depth is necessary for traction and stability on the road. Headlight brightness is also part of safety checks because properly functioning headlights are essential for visibility during nighttime driving and adverse weather conditions. These components are directly related to the vehicle's operational safety, making them essential for inspection. Comfort features, while important for overall driving experience, do not impact the vehicle's safety performance, which is why they are excluded from formal safety inspections.
