Your Maryland Inspection Certificate
How long it lasts, how to replace it, and why nothing goes on your windshield in Maryland.
Your Maryland Safety Inspection Certificate is valid for 90 days from the date it is issued. Miss that window and the inspection has to be done again, at full price. That is the one number worth writing on your hand.
Maryland does not issue inspection stickers. If you are looking for a windshield sticker, you are thinking of Virginia, Pennsylvania or New York. Maryland issues a certificate, submitted electronically to the MVA. Nothing goes on your glass. This trips up new residents constantly — and it is why a Maryland car has a bare windshield.
The 90-day clock
Maryland law sets the certificate's validity at 90 days from the date of issue. Practically, that means:
- Do not inspect too early. If you are buying a car and the sale may take six weeks to close, an inspection done on day one leaves you very little room.
- Register inside the window. The certificate has to still be valid when you present it at the MVA.
- Expired means expired. There is no grace period and no extension. The vehicle goes back on the lift and you pay again.
Dealers get a different clock
A certificate issued for a dealer's inventory lasts longer: up to 6 months, or until 1,000 miles have been added to the odometer, whichever comes first. If you are buying from a dealer and they hand you a certificate from four months ago, that can be perfectly valid — the rule is not the same one that applies to a private sale.
How the certificate reaches the MVA
Licensed stations submit inspection results to the MVA electronically. You receive your copy; the state receives its record. You do not have to carry paperwork between the shop and the MVA counter, though keeping your copy is sensible — it is your proof if a record is slow to appear.
Lost your certificate? Start with the station that performed the inspection — they hold the record and can usually reissue your copy. If the station has closed, the MVA customer service centre on 410-768-7000 (Maryland Relay 7-1-1) can tell you what is on file against the VIN.
What the certificate does and does not prove
| It proves | It does not prove |
|---|---|
| The vehicle met Maryland's safety standard on the day of inspection | That the vehicle is mechanically perfect, or will stay that way |
| The inspection was done by a licensed station | That emissions requirements are satisfied — that is VEIP, a separate programme |
| The vehicle can be titled and registered | That the vehicle has no accident history or title brand |
A safety inspection is a point-in-time check against a state standard. It is not a warranty, and it is not a substitute for a pre-purchase inspection if you are buying.
Looking up an inspection record
People search for an "MVA inspection lookup" for three different reasons, and the right answer depends on which one you are:
- You had the inspection and lost the paperwork — contact the station that performed it. Fastest route by a distance.
- You are buying and want to confirm a certificate is genuine — the certificate names the issuing station and its licence number. Call that station and verify. See our guide to authorized stations.
- You are looking for a station, not a record — that is a different search; our locations page covers our service area.
If the vehicle failed
A failed inspection produces a report, not a certificate. You have 30 days or 1,000 miles, whichever comes first, to make repairs and return for re-inspection. Past that, it is a complete new inspection at full price. Our re-inspection guide covers the rules, and the detailed walkthrough covers what usually fails and what it costs to fix.
