insurance policy limits

If I have two cars in an insurance policy is what both have to have the same limits on them?
No, I have 6 cars in my insurance policy, and three of them I am the main driver, three basic liability coverage and three with total coverage, as they are funded and addressed, some are like work cars, pleasure and business. You can have anything you want. I make sure my children, because the cars they could not afford on their own.
What is an insurance policy?
