There are millions of drivers in the country. According to the Insurance Information Institute (III), about one out of every eight drivers doesn’t have auto coverage. The number of people with insufficient policy limits is nearly the same. Adding uninsured (UM) and underinsured (UIM) motorist to your policy protects you against those types of drivers.

In this article, we’ll tell you everything you need to know about uninsured (UM) and underinsured (UIM) motorist coverage, including:

  • How UM and UIM works
  • What they cover
  • Who needs UM and UIM
  • How much they cost
  • How much UIM and UIM coverage to buy
  • Answers to frequently asked questions

Uninsured Motorist vs. Underinsured Motorist

UM and UIM both protect you from drivers lacking insurance, but they’re not quite the same. Below is a brief definition of each coverage and how they differ.

Uninsured Motorist (UM)

Uninsured motorist (UM) protects you against damages caused by motorists with no insurance. The key is that the person causing the accident doesn’t have coverage. UM also applies in a hit-and-run situation.

An uninsured motorist is someone who lacks coverage of any kind. As mentioned earlier, this policy includes hit-and-runs. Your provider would treat a hit-and-run as if a driver without insurance caused the accident.

Underinsured Motorist (UIM)

Underinsured motorist (UIM) protects you if the at-fault driver has an insufficient amount of liability insurance to cover medical-related expenses. If you don’t have UIM, you could end up paying for these costs yourself.

An important part of UM and UIM is that they both cover the car, not the person driving it. Concepts like “stacking” will become clearer when you keep this in mind. UIM and UM are often packaged together where you’d receive protection in both situations.

Another point is that a full coverage policy doesn’t include UM or UIM. These policies only include liability, collision, and comprehensive insurance. Some would argue that you don’t need UM or UIM if you have all three primary coverages. But, as you’ll see, they provide a lot of additional protection for a modest cost.

What Uninsured (UM) and Underinsured Motorist (UIM) Covers

UM and UIM coverage protect you from different things. Below is a breakdown of the protection both coverages provide:

Uninsured Motorist (UM)

There are two parts to UM coverage. Like liability insurance, bodily injuries and property damage are part of the plan. Here’s what UM includes:

  • UM property damage coverage. Pays to repair any damage to your vehicle as a result of the accident with an uninsured driver.
  • UM bodily injury coverage. Pays for any medical expenses, funeral costs, loss of income, and other expenses related to injury as a result of an accident. Also covers hit-and-run accidents. Certain states also consider passengers and family members as part of the coverage.

Underinsured Motorist (UIM)

Unlike UM coverage, there is only one type of protection that UIM policies cover:

  • UIM bodily injury coverage. Protects you from any medical costs in the event of an accident.

UM and UIM cover what the other person’s auto liability insurance can’t. This helps you avoid paying for any of the remaining expenses out of pocket.

Who Needs Uninsured and Underinsured Coverage

It’s generally a good idea to have UM and UIM. This is because you never know if a driver doesn’t have insurance. According to the III, about 13% of motorists didn’t have coverage in 2019. This number has been trending up since 2010. Additionally, states such as Florida and Mississippi had roughly 20.4% and 29.4% uninsured motorists out of all drivers in their states in 2019.

Besides the staggering number of uninsured drivers on the road, other people may need UM and UIM. For example, someone with an expensive car may want to buy them. Even if a driver with liability insurance hits your vehicle, you may still have to pay for some of the repairs if their limits are too low.

Some States Require UM and UIM

Another reason for needing UM and UIM is that your state might require it. Some states even require you to buy an equal amount to your liability insurance. Here are the states that require the coverage:

Everyone should probably have some amount of UM and UIM. It lessens the risk of having to pay for any damages that someone else causes with your money. Otherwise, you could be on the hook to pay thousands of dollars on your own.

Risks of Not Having UM and UIM on your policy

If you don’t have underinsured and uninsured motorist coverage on your auto policy, you could face some problems. Getting into an accident could cause you to end up paying for your own expenses. The goal of buying this UM and UIM is to help you avoid paying for any of your expenses in an accident. This is especially true if you don’t have collision insurance.

Uninsured and Underinsured Motorist Cost

The cost of UM and UIM motorist coverage varies from state to state. It generally costs less than other insurance types such as liability or comprehensive. There are a few factors that impact the cost of UM and UIM, including:

While these aren’t all of the factors that affect your auto rates, they could help give you a good idea of how much it’ll cost you and possibly even save you money.

The price of UM and UIM normally varies from company to company. The best way to save money when purchasing car insurance is to assess the market and compare prices to get the best value.

How Much to Buy

Many states require UM/UIM. The question is, how much should you get? Most insurers recommend buying as much insurance as possible. The benefit of buying as much as you can is to avoid paying out of pocket in situations where the expenses exceed your limits.

A good practice is to get as much UM and UIM as you have liability coverage, especially for the bodily injury component. According to Progressive, it may be the only option to choose limits that match your liability insurance.

Stacking

Stacking is a process that increases your limits based on the number of vehicles under your policy. If you insure many cars under one policy, you may be able to use the limit for each one to cover the expenses. For instance, if you have limits of $30,000 on two cars and get into an accident, your policy limit would stack to $60,000. Stacking can also work across separate policies if you choose.

Choosing to stack your limits can help save you from using personal assets to pay for an accident. You also wouldn’t need to keep your liability limits in mind to match them. The only downside to stacking coverage is that the overall cost of your UM and UIM insurance will undoubtedly go up.

Companies That Offer UM and UIM

Honestly, you can get UM and UIM from any auto insurance carrier. They must offer these coverages because they’re required by law in many states. If they aren’t required, smart drivers will still want UM/UIM included in their policies.

These are the most popular companies that offer uninsured (UM) and underinsured (UIM) motorist coverage:

Your agent may not mention UM and UIM while putting together your quote. So, if you don’t see it on your policy, be sure to ask about it. If it seems too expensive at your current insurer, shop around and compare quotes. There may be a better deal out there.

Frequently Asked Questions

What doesn’t uninsured and underinsured motorist cover?

If a driver without insurance hits you, you won’t need to worry about their expenses. As long as you aren’t liable for the accident, your UM and UIM coverage will take care of your costs alone.

If I have health insurance, are UM and UIM still worth it?

As long your state doesn’t require UM and UIM, you don’t need them. However, it would be smart to get them anyway. UM and UIM handle many things that your health care doesn’t. These include:

  • Loss of income
  • Healthcare deductibles and costs
  • In some cases, pays for the expenses of passengers and family members
  • Pain and suffering from the accident and recovery

There are far too many benefits to put off buying UM and UIM coverage if you can. Having both will ensure that your finances are in good shape after an accident.

Is uninsured and underinsured motorist coverage necessary if I have collision insurance?

It wouldn’t be necessary to purchase UM/UIM if you have collision insurance. But many states require it anyway. There are still benefits to carrying some amount of UM and UIM coverage. For instance, it will make sure you’re fully protected from property damage expenses.

An extra thought to consider is that collision usually costs more. And, after an accident, your rates could rise. Putting in a claim for UM and UIM helps to avoid those risks.
