PA Inspection Sticker Color System
Pennsylvania uses a rotating color scheme that changes each year, allowing law enforcement to quickly identify expired inspections.
Annual Color Rotation
- 2024: Green stickers
- 2025: Red stickers
- 2026: Blue stickers
How to Read Your Inspection Sticker
- Expiration Month: Large number in center (1-12)
- Expiration Year: Four digits at bottom
- Station Number: Inspection station certification number
- Inspection Type: "S" for safety only, "S/E" for safety and emissions
Where Stickers Must Be Placed
The sticker must be placed on the lower right corner of the windshield (passenger side), visible from outside but not obstructing the driver's view.
Understanding Expiration Dates
Your sticker expires at the end of the month shown. If it shows "3" and "2025," it expires March 31, 2025 at 11:59 PM.
No grace period: Pennsylvania does not provide a grace period for expired inspections.
Rejection Stickers
If your vehicle fails, you receive a white rejection sticker with red "R" designation, valid until the end of the following calendar month.
Lost or Damaged Stickers
Return to the original inspection station within 10 days for free replacement. After 10 days, you may need to pay a fee or get re-inspected.
