Which safety features are assessed during the inspection?

Answer: B — Seat belts and airbag systems.

During a Pennsylvania Enhanced Vehicle Safety Inspection, the assessment of safety features is a critical part of ensuring that vehicles are safe for operation on public roads. Seat belts and airbag systems are essential safety components in any vehicle, as they play a significant role in protecting occupants during a crash. Inspectors evaluate the condition, functionality, and proper installation of seat belts, ensuring that they can effectively restrain passengers. Additionally, the airbag systems must be checked to confirm that they are operational and capable of deploying in the event of an accident, providing an additional layer of safety. The other options focus on different aspects of vehicle performance or maintenance that, while important, do not directly pertain to the core safety features necessary for occupant protection in the event of a collision. This makes the assessment of seat belts and airbag systems a priority during safety inspections.
