Keep a proof of insurance card in your vehicle at all times. Most states require drivers to carry proof of insurance cards, sometimes called “insurance ID cards.” It isn’t a bad idea to keep another copy in your wallet, too. Since identity theft is so widespread, store your vehicle title and registration at home. If you are required by state law to carry a copy of your vehicle registration, keep it in your wallet or locked glove compartment. (Source of information: http://www.freeadvice.com)
