A certified pre-owned vehicle has passed a manufacturer-defined inspection and carries a warranty backed by the manufacturer rather than the dealer. Programmes usually restrict eligibility by age, mileage and title status.
The important distinction is between manufacturer certification and a dealer's own certified label. The latter is a marketing term with whatever meaning the dealer chooses to give it, and is backed only by that dealer.
Certification does not erase history. A vehicle can be certified and still have had an accident, provided it meets the programme's criteria.
Why it matters
You pay a premium for the warranty, so it is worth confirming that the warranty is the manufacturer's and reading what it actually covers.
How to check it
Ask who underwrites the warranty, get the inspection checklist, and run the history independently rather than relying on the badge.
Does this apply to the car you are looking at?
Run the VIN or plate and see what is actually on record.

Definitions are general guidance, not legal advice. Title rules, total loss thresholds and inspection requirements are set by each state and change over time, so confirm the position with the motor vehicle agency for the state the vehicle is titled in before relying on it.
