What is the required size for the inspection station sign displayed outside the garage?

The required size for the inspection station sign displayed outside the garage is indeed 24 inches high and 21 inches wide. This specific size is mandated to ensure that the sign is easily visible to the public and maintains uniformity across inspection stations, facilitating recognition and compliance by both consumers and regulatory authorities.

A sign of this dimension helps convey important information effectively without overwhelming pedestrians or drivers in the vicinity. The height and width measurements strike a balance that ensures clarity from a reasonable distance, making it effective for identification purposes. This standard contributes to the overall integrity of vehicle inspection processes by reinforcing legitimate operations that meet state regulations.

When evaluating other options, they do not conform to the established requirements in terms of size and visibility, which underscores the importance of following the specified dimensions for inspection station signage as set forth by Pennsylvania regulations.
