Car Insurance for Roommates

You share a roof together — but should you share your car insurance?

What does car insurance for roommates look like?

Having a roommate is a pretty common occurrence for most people. It’s a great way to split the cost of living and, unless you have a particularly bad roommate, a good way to spend your time. Still, there are some issues that come with living with your roommate in terms of your auto insurance you might not consider. Let’s break it down.

In this article, we will discuss:

  1. Does my roommate need to be on my car insurance policy?
  2. Okay, so when should I add my roommate to insurance policy?
  3. And when shouldn’t I?
  4. What about sharing my renters insurance?
  5. What’s my takeaway from all of this?

Roommates and car insurance

As a general rule, anyone that lives with you needs to either be added to your car insurance policy, or be an excluded driver. This has to do with the increased likeliness of your roommate, given their location, will use your vehicle and might file a claim. If your roommate is not a rated driver (someone on your policy), your insurance company hasn’t had a chance to evaluate them as a risk or rate them for that risk.

When should you add your roommate to your policy?

If you want an added discount

Usually, when you add your roommate and their vehicle to your policy, you are eligible for a multi-car discount. Now, the amount of the discount per underwriting rules, any discount is worth considering.

If you want to use their vehicle (and vise versa)

As the only options are excluding/adding, if you add your roommate to your policy, you are both able to switch vehicles as you like and need. So if your car breaks down and you need to borrow your roommates for a week, you will be covered in the event of an accident. However, if you are excluded, you wouldn’t have coverage and thus are encouraged not to use their vehicle.

When to keep your policy separate?

If they have a bad driving record

If your roommate has a bad driving record, i.e., lots of at-fault accidents or citations, your bill will be higher because they are being rated on your policy. Keeping your policy would ensure you are not financially penalized for their driving mistakes.

If they have poor credit

Most insurance companies and most states use your credit score as a determining factor for your premium. Just like having a poor driving record, having a low credit score can negatively impact your premium significantly.

If they have an expensive car

If you drive a Toyota Corolla but your roommate drives a Lamborghini, you should expect a significant difference in your premiums. Your insurance company has to soften the risk of insuring such a high-value car by charging a high premium. If you’re worried about footing the bill for their fancy and expensive car, think about getting your own policy.

Renters Insurance and Roommates

Unlike your car insurance, your renters insurance isn’t as strict as your auto. You are welcome to have a joint or separate renters insurance policy as you wish. Check out our ins-and-outs for renters insurance.

The big thing to take away from car insurance when you have a roommate is the requirement to either add your roommate or exclude them from your policy. Because of the high chance of sharing vehicles, your insurance company wants to know who they are doing business with. They, understandably so, want to evaluate all risks posed to them. If you’re worried about your roommates driving profile hurting your premium, exclude them from your policy. If, however, you and your roommate want the ability to share vehicles or be eligible for a discount, you should add them to your policy. At the end of the day, the best way to save on your auto insurance is to shop around for car insurance (with or without your roommate) every 6 months.
