The safety rating for a Sports Utility Vehicle is a rough measurement done by an organization like the Insurance Institute for Highway Safety of the relative safety of a vehicle. Vehicle models that receive the highest safety ratings receive the Top Safety Pick award.
Safety ratings for SUVs, as well as any other type of automobile, are typically determined by standards set by the National Highway Traffic Safety Administration. The NHTSA is a branch of the Department of Transportation of the United States government, which had predecessor organizations formed as early as 1966 following a movement for vehicle safety. They develop the testing dummies that can be found in modern media that test the safety of vehicles in a crash.
