The program's main goal is to provide police, security device dealers, and vehicle sellers with a list of recognized security devices that have passed rigorous testing. The list can be used by vehicle sellers to recommend suitable vehicle security systems to customers. Since its inception, Sold Secure has tested 246 security devices. Thirty-five percent have been included on a list of recognized security devices. Fifty-seven percent of those passing the testing were electronic immobilizers; 24 percent were mechanical devises. In 1994, 4,113 vehicles were fitted with recognized security devices by members of the Sold Secure program. Vehicles fitted with products recognized by Sold Secure have a likely risk of theft of between 2.8 and 18.5 vehicles per 1,000 registered, compared to the national rate of 21 thefts per 1,000 vehicles registered. However, it was not possible to determine whether the actions of people who bought such devices were different from the general population of vehicle owners.
