You can find safety ratings from several organizations, including:
* IIHS (Insurance Institute for Highway Safety): They conduct rigorous crash tests and award ratings like "Top Safety Pick" or "Top Safety Pick+" based on performance. Check their website (iihs.org) and search for the specific year and model of the Silverado 1500.
* NHTSA (National Highway Traffic Safety Administration): This U.S. government agency provides overall safety ratings based on crash tests and other safety features. You can find their ratings on their website (nhtsa.gov) using their vehicle search tool.
In short, you'll need to do a little research on the specific year of the Silverado 1500 you're interested in on the IIHS and NHTSA websites to get the most accurate and relevant safety information.
