Underinsured Motorist (UIM) Coverage is a type of auto insurance protection designed to cover expenses when an at-fault driver does not have enough insurance to pay for all damages incurred in an accident. It ensures that you are not left financially vulnerable due to another driver’s insufficient coverage.
How Underinsured Motorist Coverage Works
When you are involved in an accident where the at-fault driver’s insurance is not sufficient to cover all the damages, UIM coverage steps in to fill the gap.
For instance, if your medical bills and vehicle repairs amount to $50,000 but the other driver’s policy only covers $25,000, your UIM coverage would pay the remaining $25,000 (up to your policy limits).
Examples of Underinsured Motorist Coverage in Action
Example 1: Medical Expenses Coverage
John is driving home when another driver runs a red light and crashes into his vehicle. John’s medical bills total $80,000. The at-fault driver’s liability insurance only covers up to $30,000. Fortunately, John has UIM coverage of $100,000, which pays the remaining $50,000.
Example 2: Vehicle Damage Protection
Sarah’s car is worth $40,000, and she gets into an accident caused by an underinsured driver whose insurance policy only covers $20,000. Sarah’s UIM coverage pays the remaining $20,000 to repair or replace her car.
Example 3: Hit-and-Run Scenario
Mike is hit by a driver who flees the scene. Since the identity of the driver is unknown, Mike’s uninsured/underinsured motorist coverage helps pay for his medical bills and vehicle damage.
Advantages of Underinsured Motorist Coverage

1. Financial Protection
Without UIM coverage, you may have to pay out-of-pocket for expenses that exceed the at-fault driver’s liability coverage. This policy ensures you are protected from unexpected financial burdens.
2. Covers Medical Expenses
Medical treatments can be expensive. UIM coverage helps cover hospital bills, rehabilitation costs, and even lost wages if you are unable to work due to injuries.
3. Protects Against Hit-and-Run Accidents
If a driver responsible for an accident flees the scene, UIM coverage can step in to cover damages and medical costs.
4. Covers Pain and Suffering
Some policies may include compensation for pain and suffering that result from an accident caused by an underinsured driver.
5. Affordable Additional Protection
UIM coverage is generally inexpensive to add to an existing auto insurance policy, making it a cost-effective way to enhance financial security.
How to Determine If You Need UIM Coverage
- Do You Live in a High-Risk Area? If you live in an area with a high rate of uninsured or underinsured drivers, having UIM coverage is essential.
- Do You Have Health Insurance? While health insurance may cover medical bills, UIM coverage provides additional benefits, such as lost wages and pain and suffering compensation.
- Is Your Car Valuable? If you own an expensive vehicle, you may want UIM coverage to ensure repair or replacement costs are covered in an accident.
How Much UIM Coverage Should You Have?
The amount of UIM coverage you need depends on factors such as your state’s insurance requirements, your financial situation, and the level of risk in your area. Generally, experts recommend carrying at least the same limits as your bodily injury liability coverage.
