Start a vehicle safety comparison with an exact model year and equipment specification. Then separate three questions: how the design performed in testing, which crash-avoidance features this vehicle has, and what condition it is in today.
A strong rating can help you build a shortlist. It cannot answer every question about a particular used car, its repairs, or its fit for the people who will travel in it. Keep the evidence on separate lines so an attractive headline does not hide an unanswered question.
Make sure the evidence belongs to this vehicle
Record the model year, body style, market, trim, VIN, build date and relevant options. Save the seller's equipment description, then mark each item as verified or unconfirmed. A badge or a photograph of a dashboard button is a clue to investigate.
Search the NHTSA ratings database and IIHS vehicle ratings for the exact model. Read applicability notes before transferring a result from a nearby year or trim. If a listing and the official record disagree, ask the manufacturer or dealer to resolve the specification.
Compare results within their test boundaries
On a narrow screen, scroll the table sideways. Keyboard users can focus the table region and use the arrow keys.
| Evidence | What to record | Comparison check |
|---|---|---|
| NHTSA frontal and Overall scores | Model year, vehicle class, weight and result. | NHTSA limits comparisons to the same class and similar weight, within 250 pounds. |
| NHTSA side and rollover scores | Individual scores and explanatory notes. | NHTSA permits comparison across vehicle classes; keep the separate test labels visible. |
| IIHS crashworthiness | Named test, version, result and applicable vehicles. | Check whether the result is from an original or updated test. |
| Avoidance and lighting | Named system, conditions tested and required equipment. | Confirm that the candidate actually has the rated configuration. |
NHTSA's explanation also identifies safety-concern symbols that are separate from the Overall score. Read the notes, and treat “Not Rated” as missing test evidence rather than a failing score. See NHTSA's rating explanations.
IIHS has replaced several original evaluations with more demanding versions. An unchanged word such as “good” does not establish that two vehicles faced the same test. IIHS also reviews structural and equipment information when determining whether results carry over to other model years. Use its test-method explanations to interpret the named result.
Check the fitted equipment and passenger fit
IIHS advises checking build-date restrictions and equipment conditions attached to awards. Its child-seat attachment ratings assess ease of use; they do not replace checking whether your own restraint fits correctly. Bring the seats and occupants relevant to your household when evaluating a candidate. See IIHS shopping guidance.
For every feature you expect to use, record its exact name, manual section, controls, warning indicators and limitations. Keep warnings separate from systems that can intervene. The guides to verifying electronic stability control and lane warnings and steering assistance help with those specific checks.
Evaluate the car that is for sale
Run a VIN search through NHTSA's recall lookup and record the date and any outstanding action. Its results have coverage limits, including some older recalls, and do not show already completed recalls. Ask the manufacturer to resolve an uncertain repair history.
Arrange an independent vehicle inspection and give the inspector your unresolved questions about collision repairs, restraints, tires, brakes, warning lights and assistance systems. Keep the inspection findings alongside the ratings. A test result for a vehicle design does not document the condition of this individual example.
Finish with a decision and a list of unknowns
Download the safety comparison record. Complete one copy for each candidate, using the same passenger needs and comparison questions. Save links and dates so you can revisit the evidence.
Label each conclusion “supported,” “unconfirmed,” or “not comparable.” End with a practical next step: obtain an equipment record, ask about a recall, commission an inspection, or remove a candidate from your shortlist. This is a decision record, not a new safety rating.
