Your vehicle must be insured before you drive it off the dealership lot. If you drive uninsured and you're caught, you could have your license suspended, and you may even be fined. The good news is that if you already have an auto insurance policy, your new vehicle will be covered under the policy at the same level as your existing vehicles. Just make sure you add the new car to the policy as soon as possible to avoid having that grace period lapse. If you don't have an insurance policy in place, you'll need to arrange to have the vehicle insured before you drive it home. You can do this by providing as much information as you have before you buy, then adding the specific vehicle details once you know them.
