Can I Buy Auto Insurance In Another State? 
You can but there would have to be some reason . For example , if you reside in one state , but have a vacation home in another , and you want to avoid the wear and tear on one of your primary cars , you may want to register a car in the state in which your vacation property is located . In that case , due to states registration regulations which require proof of insurance issued in the registering state , you would obtain coverage for that car in that state .
