Frequently Asked Questions

Can two cars be on the same insurance policy?

Yes. A multi-car policy puts two or more vehicles under one policy number, and each vehicle can carry its own coverage level. The policy earns the multi-car discount when all vehicles are combined.

Does each car on a multi-car policy need the same coverage?

No. Each vehicle can carry liability only or full coverage independently. One car can have full coverage while another carries state minimum liability, and both stay on the same policy.

How does the multi-car discount work?

The discount applies when you insure two or more vehicles on a single policy. The carrier reduces the total premium because administrative cost per vehicle drops when multiple cars share one policy.

Is one multi-car policy cheaper than two separate policies?

Typically yes. Combining vehicles under one policy earns the multi-car discount and eliminates duplicate policy fees. The total premium for one multi-car policy is usually lower than the sum of two single-car policies.

Do all vehicles on a multi-car policy need the same garaging address?

Most carriers require every vehicle on the policy to be garaged at the same address to qualify for the multi-car discount. Some allow exceptions for college students or military members temporarily stationed elsewhere.
