A five-star car is not a car that will never be recalled. Star ratings measure how well a car protects people in a crash test; recalls fix defects found later. Here is how the US government's 5-Star Safety Ratings work, and how to use them with a recall check.
The four tests
- Frontal crash: the car hits a fixed barrier at 35 mph; injuries to head, neck, chest and legs are measured.
- Side barrier: a 3,015 lb barrier hits the standing car at 38.5 mph.
- Side pole: the car, angled at 75 degrees, is pulled sideways at 20 mph into a pole at the driver's seat.
- Rollover: how top-heavy the car is (its Static Stability Factor) plus a driving manoeuvre test.
The overall score combines the frontal, side and rollover results, weighted by how often each kind of crash injures people on real roads.
What the stars mean
- 5 stars: injury risk much less than average.
- 4 stars: less than average to average.
- 3 stars: average to greater than average.
- 2 stars: greater than average.
- 1 star: much greater than average.
A warning symbol next to a rating marks a safety concern the testers saw, such as a structural failure or a fuel leak. It is not part of the score, so a car can have high stars and still carry one.
What you can and cannot compare
NHTSA says frontal and overall scores should only be compared between vehicles in the same class and within 250 lb of each other. Side and rollover results can be compared across classes. So a 5-star small car and a 5-star large SUV are not equally safe in a head-on crash with each other; each is good for its class.
Stars and recalls are different things
Ratings are set when a model is new. Recalls come later, when a defect turns up, and they apply to the exact cars built in a given window. A highly rated car can have many recalls, and a car with few recalls can rate poorly. Check both: the ratings at NHTSA, and the recalls for your own car by VIN. To see how many recalls a model has had, make its recall card, or see its best and worst years.
Other ratings you will see
The Insurance Institute for Highway Safety (IIHS), funded by insurers, runs its own, different crash tests and awards. In Europe, Euro NCAP publishes star ratings on its own tests. The three are not interchangeable: read each on its own terms.
Driver assistance to look for
NHTSA lists forward collision warning, lane departure warning, crash imminent braking and dynamic brake support as recommended technologies, alongside the basics: air bags, seat belts and tire pressure monitoring.
Quick answers
What does a 5-star safety rating mean?
In NHTSA's 5-Star Safety Ratings, five stars means the overall injury risk in its crash tests is much less than average. One star means much greater than average.
Can you compare safety ratings between a car and an SUV?
Not for frontal or overall scores: NHTSA says to compare those only within the same class and within 250 lb. Side and rollover results can be compared across classes.
Can a 5-star car be recalled?
Yes. Star ratings measure crash protection when the model is tested; recalls fix defects found later in specific cars. Check your own car's recalls by VIN.
