Behind the rollover ratings NHTSA's SUV rating system doesn't say much. We dug deeper to help you find where they really rank. Rollover crashes are a particularly deadly type of accident. But it can be hard to tell, based solely on National Highway Traffic Safety Administration's star ratings for rollover resistance, which SUVs are least likely to roll over in a crash. NHTSA bases its ratings primarily on something called the Static Stability Factor. This is calculated by comparing a vehicle's width to its center of gravity. Whether a vehicle tips up on two wheels in a driving test also plays a small role in the rating. For our more on how the ratings work, see our story. Below is a table of NHTSA test results for all 2004 model year SUVs that have been assigned a rollover resistance rating so far. For more details, see the notes below the table.
Notes: Chances of rolling over in a single-vehicle crash. 4 stars: 10 to 20 percent 3 stars: 20 to 30 percent 2 stars: 30 to 40 percent No SUVs have 1 star of 5 stars |
