I have full coverage auto insurance, so is anyone who drives my car covered? 
It would be best that you speak to your Agent/Broker or Insurance company for detail explanation of your policy . But It depends on your policy or state as to whether it would be covered or not.To answer your question `` In small word 's '' if you voluntarily hand your keys and lend your vehicle to someone else -LRB- your brother getting some food at the super market -RRB- then yes they would be covered . Now the only policy that i seen that would not covered it is a Texas policy that is called Named Driver only policy in which you name who are the only persons that would be covered under that policy . I can only speak for NYS so I would advice you to speak to your agent or company if they would covered this type of accident . Thank you .
