How does multi-car insurance work?

A multi-car policy provides coverage to multiple vehicles on a single policy. There is no difference in coverage options or what the policy provides, but insurance companies offer a discount for insuring more than one car. 

All of your premiums will appear on one insurance bill, although each is listed separately and can have different coverage. Most car insurance companies offer multi-car insurance and will give you a discount.

Some have policies specifically designed for more than one car, while with others, it's simply more than one car listed on the same account. There may be a single or multiple policy numbers, one for each car. Either way, nearly every company will discount the rates.

How much can you save with multi-car insurance?

You can save as much as 25% with a multi-car discount, although the discount varies by company. As a general rule, the discount is the same no matter how many cars are on the policy.

The discount insurance companies advertise is the overall savings on the policy as a whole and doesn't apply to each policy individually.

Which company has the best multi-car discount?

Geico has the best multi-car insurance discount at 25% among those companies we compared. Here’s how several top companies stack up.

It’s important to remember that the amount of the discount doesn’t always mean the lowest rate. Car insurance rates can vary from company to company, so the rate might be better even if the multi-car discount is smaller.

That’s why comparing car insurance quotes from multiple insurers is important.

What are the benefits of a multi-car policy?

There are a few perks to insuring more than one car on a single policy.

  • Discounts. Most insurers offer a fairly big multiple auto insurance discount. While it varies by insurer, you can expect up to 25% savings with a multi-car policy.
  • Single insurance deductible for all vehicles damaged in a single incident (in some cases). Although not all companies offer it, some will charge the deductible only once if more than one insured car is damaged in the same incident, such as a storm.
  • Car insurance stacking. In states that allow it, you can stack your uninsured or underinsured bodily injury motorist (UM/UIM) coverage when you have multiple vehicles on the same policy.
  • One renewal date. All of your cars will have coverage renewed at the same time.
  • One bill. You’ll only have one car insurance bill to worry about.

PEOPLE ASK

Are there limits to how many drivers can be added to a multi-car insurance policy?

You can have as many drivers as you want on your auto insurance policy. All drivers in your household should be listed on your policy; it's not necessary to list non-household members who use you car occasionally.

What are the requirements for a multi-car policy?

The basic requirement for a multi-car discount is that all cars be kept at the same address. After that, car insurance companies’ rules vary. Some insurers offer a discount only if the insured autos are in the same household and insured by related parties. Other insurers will give non-related people a discount as long as they live together.

Some insurers will go a step further and even give a multi-vehicle discount to residents at the same address, even if you have separate car insurance policies with them. There may be a limit to the number of cars you can have on a single policy. Usually, the maximum is four or five. 

You can qualify for the discount mid-term if you place an additional car on your policy. Conversely, the discount will fall off if you remove a car mid-policy and now insure a single vehicle.

What are the coverage options on a multi-car policy?

Coverage options for a multi-car policy are the same as any other car insurance policy. You can select your liability limits, add comprehensive and collision, select your deductible for each car, and add any other options to your policy.

If you have multiple cars in your household, you might not need to add rental car reimbursement; one of the benefits of owning more than one car is having a spare on hand.

PEOPLE ASK

Can I customize the coverage levels for each car on my multi-car insurance policy?

Yes, although you will likely have to carry the same liability coverage limits on each car. Beyond that, you can add and subtract optional coverage on each vehicle.

Does the coverage need to be the same on each vehicle?

Most insurance companies require that you have the same amount of liability insurance and uninsured motorist coverage on each vehicle, but when it comes to collision and comprehensive and other options, it varies.

You can usually carry collision and comprehensive on one car and not another. The same applies to add-on coverages, such as rental reimbursement or custom car and equipment coverage.

Remember that the insurance follows the car, and coverages don’t cross over.

When a claim is filed, only the coverage on the car involved will apply. So, if one car has full coverage (collision and comprehensive) and one has only liability, the liability-only car will not be covered if it’s damaged.

How many cars can I insure on one policy?

The rules depend on the company, but most will allow you to have four to five cars insured on a single policy. More cars than that will indicate to the insurance company that you might be running a business and need a different type of insurance.

If you legitimately have and use more than five cars for your family, speak to your insurance company about your options.

Is it cheaper to have three cars on one multi-car insurance policy?

In most cases, it's cheaper to insure all of your vehicles on one policy than to insure them separately. Every vehicle insured on the policy will get a discounted rate.

Can I add someone who isn’t a family member to my multi-vehicle insurance policy?

You can add a non-family member to your policy if they drive your car often enough to warrant it. However, auto insurance companies allow permissive use of your vehicle, which means others can drive it occasionally and be covered without being on the policy.

Can you get a no-claims discount on multiple cars on your multi-car insurance policy?

Discount rules vary by the insurance provider, but in general a no-claims discount should apply to all vehicles on the policy.

Frequently asked questions about multi-car policies

Can roommates get multi-car discounts?

It's possible for roommates to share a car insurance policy and therefore get the discount for having two or more cars on one policy.

Can you add a car to your insurance policy online?

Most insurance companies allow you to add a car online, but you must check with your insurer.

Can you have two car insurance policies on the same car?

Yes, you can have two insurance policies on the same car; however, it doesn’t make much financial sense. You are better off increasing the coverage levels on one policy. You can't get two payouts for the same incident, so there's no reason to carry two policies.

Can you have two car insurance policies on two different cars?

You can have two car insurance policies on different vehicles, but you'll likely pay more for insurance.
