Insurance ID card are included for each insured vehicle with each 6-month new business policy and policy renewal package sent to you in the mail. A new insurance ID card will automatically be sent to you for each new vehicle you add to your policy. If you buy a new or used car, the dealership will require proof of auto insurance before you leave the lot. In most states, you can use a current declarations page or ID card for another vehicle as valid proof of insurance for a minimum of 14 days until you receive your ID card in the mail.
