How often must vehicles in Pennsylvania undergo a state inspection?

Vehicles in Pennsylvania are required to undergo a state inspection annually, meaning they must be inspected once every 12 months. This requirement is in place to ensure that vehicles on the road meet safety standards and are in good working order. The annual inspection helps identify any potential safety hazards or mechanical issues that could pose a danger to the vehicle's occupants or other road users. The consistent frequency of this inspection plays a critical role in maintaining safe driving conditions and vehicle reliability.

The other options, which suggest more frequent or less frequent inspections, do not align with Pennsylvania's regulations. The state recognizes the need for regular assessments to prevent accidents caused by vehicle malfunctions, thus implementing the annual requirement for inspections.
