What the ratings mean
NHTSA gives the 2018 GMC Sierra 2500 4 out of 5 stars overall. NHTSA does not publish enough comparable results for this class and year to rank it against peers.
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 20.4% in a single-vehicle crash — the figure behind the rollover star rating, published here because the star alone hides how wide each band is.
