Under the old rules, you would be responsible for the vehicle in front of your vehicle - even if the vehicle behind your vehicle pushed you into it. It may vary from state to state, but you are supposed to be back a full car length from the vehicle in front of your vehicle. However, these days, the person who starts the accident is usually liable for the property damaged - all of it. Now, you will want to immediately contact the insurance company of the driver who started the accident - especially if his insurance company will be responsible for multiple vehicles (one being an suv). He will have purchased a set amount of "property damage liability" insurance, and his insurance company will not pay anything above this limit. You will also want to contact your insurance company - even if they do not pay for anything resulting from this accident. It will protect their financial interests. Also, your rates should not go up for reporting an accident. They should only increase if your insurance company has to pay out a claim.
