Should both mechanics involved in the inspection sign the sticker?

In the context of Pennsylvania's State Safety Inspection process, both mechanics involved in the inspection must sign the sticker. This requirement is in place to ensure accountability and traceability in the inspection process. When both mechanics sign the sticker, it indicates that they have both participated in the inspection, affirming that all safety checks have been duly performed and that the vehicle meets the required safety standards.

Furthermore, having both signatures helps maintain a clear record of who is responsible for the inspection, which is essential in the event of follow-up issues or disputes regarding the vehicle's condition. It promotes adherence to safety regulations and a thorough examination of the vehicle, ensuring that all aspects of the inspection process are covered.

The other choices do not reflect the requirement for both mechanics to sign, as they suggest either a single signature or no signatures at all, which would compromise the accountability structure established in the inspection process.
