Sticker and registration dates
Since 2005, Pennsylvania no longer requires the inspection sticker expiration and the vehicle registration expiration to coincide for annually inspected vehicles. Owners can ask that the two match, but this may result in a shortened inspection cycle at first. PennDOT publishes charts for annually inspected vehicles that show whether coordinating the dates would shorten the cycle. Motorcycle inspection expirations are based on the expiration of the registration.
Where to inspect
Safety inspections are performed only at official PennDOT inspection stations. PennDOT lists the active safety stations on its site. To contact a Quality Assurance Officer about a safety inspection, PennDOT publishes a contact list organized by geographic area.
Modified, rebuilt and specially constructed vehicles
Since January 1, 2007, only stations appointed by PennDOT as Enhanced Vehicle Safety Inspection Stations may inspect reconstructed, flood, specially constructed, recovered theft, collectible and modified vehicles and street rods for compliance with equipment and inspection rules for titling the vehicle in Pennsylvania.
What the passenger car safety inspection covers
For passenger cars and light-duty trucks, PennDOT states that these items are checked:
- Suspension components and steering
- Braking systems
- Tires and wheels
- Lighting and electrical systems
- Glass (glazing), mirrors, windshield washer, defroster and wipers
- Fuel system
- Speedometer and odometer
- Exhaust system
- Horn and warning devices
- Body and chassis
The complete list of rejection criteria is in Section 175.80 of Subchapter E of Pub 45, PennDOT's Vehicle Equipment and Inspection Regulations. Medium and heavy-duty trucks and buses, trailers, motorcycles and motor-driven cycles have their own criteria in other subchapters of Pub 45.
Visual anti-tampering check in the 42-county region
For most vehicles in the 42-county Non-I/M region, the safety inspection also includes a Visual Anti-Tampering Check. It is an examination of the vehicle to see whether the required emissions components have been tampered with or removed.
How emissions testing is organized
Pennsylvania's emissions inspection program was customized for regional air-quality issues and goals. PennDOT points to separate information for the Pittsburgh, Philadelphia, South Central and Northern regions and for the other counties. The test your car needs depends on where it is registered, so check your county on the official Drive Clean PA site: drivecleanpa.state.pa.us. Consumers with emissions questions can call 1-800-265-0921.
Fees
Inspection fees are posted at official inspection stations, and they do not include repairs. Compare what a station posts with what you are charged, and ask what the posted fee covers.
