What this rating means for the 2018 Nissan Altima
NHTSA gives the 2018 Nissan Altima 5 out of 5 stars overall, level with the 5-star median for the 16 comparable 2018 vehicles NHTSA rated in this class. That places it at the bottom of its tested class. A five-star overall is common in recent model years, so it separates a vehicle from its rivals less than it once did.
NHTSA published results for every NCAP test in this program, so the overall star rating rests on a complete set of crash and rollover results.
NHTSA's dynamic test put this vehicle's rollover probability at 10.3% in a single-vehicle crash — the figure behind the rollover star rating, published here because the star alone hides how wide each band is.
Across the 11 model years we hold for the Nissan Altima, this figure has not moved from 5-star.
A star rating describes how this vehicle performed in NHTSA’s tests against other vehicles of similar mass. It is not comparable across weight classes: five stars on a small car and five on a large SUV do not describe equal crash outcomes.
About NHTSA Safety Ratings
The NHTSA New Car Assessment Program (NCAP) assigns 5-star ratings from government-funded frontal, side, and rollover crash tests — not manufacturer-reported data. Ratings, crash media, and safety-technology data are sourced directly from NHTSA.
