How Uninsured or Underinsured Auto Insurance Coverage Works

There are many different types of auto insurance coverage, and understanding how auto insurance works will ensure you get the best coverage for your needs. Uninsured or underinsured auto insurance coverages protect you if you are hit by a driver who either doesn’t have insurance or doesn’t have enough insurance to cover your bills.

You will have to file a claim after a UM/UIM qualifying accident with your insurance company, and it will handle the rest. You can read our guide on State Farm uninsured/underinsured motorist claims for an idea of how claims for UM/UIM coverage work.

If you live in a state where drivers are prone to driving without insurance or carrying minimum insurance only, UM/UIM coverage can be a great add-on to your policy.

The Difference Between Uninsured/Underinsured Auto Insurance Coverage

Uninsured and underinsured auto insurance coverage are sold separately, but most drivers often carry them together. The difference between uninsured and underinsured coverages is that underinsured motorist insurance is for when the driver that hits you doesn’t have great coverage.

An underinsured motorist coverage example would be if the driver has only a $10,000 limit of property damage liability insurance, but your car repairs cost $15,000. In this case, underinsured motorist coverage will pay the difference.

On the other hand, uninsured motorist insurance is for when the driver that hits you doesn’t have insurance, like with hit-and-run accidents. In this case, uninsured motorist insurance will cover your bills up to the policy limit. Without uninsured motorist insurance, your
average uninsured motorist settlement may not be enough to pay off your accident bills.

The bodily injury part of the coverage will help pay for your medical bills if you are injured in an accident caused by another driver who is uninsured or underinsured.

Uninsured/Underinsured Coverage vs. Full Coverage Auto Insurance

Full coverage auto insurance will cover your accident costs if you are hit by another driver. It will also cover other parties’ accident costs if you hit them. However, it will usually not cover you if the driver can’t afford to pay all of your accident bills or doesn’t have insurance, as this is covered under uninsured or underinsured motorist coverage.

UM/UIM insurance provides additional protection in states that have low coverage requirements or a high amount of uninsured drivers.

We do recommend that drivers purchase affordable full coverage auto insurance, as it provides the best protection in a variety of situations, whether you hit a deer or back into another car in a parking lot.
