California Governor Jerry Brown recently signed AB 1215 into law. The new law, which takes effect in July 2012, mandates that both new and used car dealers run their used cars through the National Motor Vehicle Title Information System to check for problems, and place a warning sticker on used cars with a shady past. According to the New York Times, the national database was created as a repository for information about vehicles deemed unsalvageable because of flood, fire, or crash damage. The bill’s proponents argued that the national registry, which is supplied information by insurance companies, salvage yards, and junkyards, is more comprehensive than commercial services like Carfax. The law is the first of its kind in the nation, and will hopefully afford consumers an additional layer of protection when purchasing a used vehicle.
