PA Emissions Inspector Certification Practice Exam

Which vehicles are exempt from the emissions program test but still require a sticker?

1. Vehicles over 15 years old

2. New vehicles with under 5,000 miles

3. Converted vehicles

4. Commercial vehicles

The correct answer is: New vehicles with under 5,000 miles

New vehicles with under 5,000 miles are exempt from the emissions program test because they are likely to have lower emissions due to their newness and the higher standards they meet during manufacturing. These vehicles typically have not yet experienced significant wear and tear, which can impact emissions performance. However, they still require a sticker to indicate compliance with registration requirements. This sticker serves as a visual confirmation that the vehicle is compliant with the emissions program guidelines despite being exempt from the testing requirement. In contrast, other categories—such as vehicles over 15 years old, converted vehicles, and commercial vehicles—may have different regulations concerning emissions testing and sticker requirements. These vehicles often do not qualify for the same exemptions based on age or modification status, which explains why they wouldn't fit into the noted exemption setup.
