Florida recently joined a growing list of states that allow electronic proof of insurance via smartphones for motorists at traffic stops. Among Southeastern states, Mississippi, Alabama, Georgia, Tennessee and Kentucky now also allow electronic proof of insurance. Nationally, there are now 25 states that allow electronic proof of coverage at traffic stops, as of June 17, according to a new map prepared by the Property Casualty Insurers Association of America (a PDF file). These states allow drivers to show proof of insurance using a smartphone.
