Auto insurance is something most drivers in the United States have to think about regularly. It’s an essential part of responsible car ownership, but the complexity of different policies can be confusing. In this article, I will explain the four major types of auto insurance: liability, collision, comprehensive, and uninsured/underinsured motorist coverage. I will go into detail about each type, explaining their benefits and how they work, and I will also provide some real-world examples with calculations. By the end, you should have a much clearer understanding of your options when it comes to auto insurance.

Liability Insurance
Liability insurance is one of the most common and required forms of auto insurance in the United States. In fact, every state except for New Hampshire requires drivers to have liability coverage. Liability insurance is divided into two categories: bodily injury liability and property damage liability.
Bodily Injury Liability covers the costs if you are at fault in an accident that injures another person. This could include medical bills, lost wages, and legal expenses if the injured party decides to sue you.
Property Damage Liability covers the cost of repairing or replacing someone else’s property if you’re at fault in an accident. This includes other vehicles, fences, buildings, and other objects that could be damaged.
Let’s say you are involved in an accident, and the other driver sustains medical bills totaling $10,000, and their vehicle requires $8,000 worth of repairs. If you have bodily injury liability of $50,000 and property damage liability of $25,000, your insurance will cover the costs up to those limits. If the damage exceeds your policy’s limits, you could be personally liable for the rest.
Example Calculation for Liability Insurance:
- Bodily injury liability limit: $50,000
- Property damage liability limit: $25,000
- Accident results in $10,000 medical bills and $8,000 vehicle repair costs.
Your insurance will cover the $10,000 medical bills and $8,000 vehicle repairs. If your liability limits were exceeded, you would be responsible for the remaining costs.
| Coverage Type | Coverage Limit | Accident Costs | Amount Covered by Insurance | Amount You Pay |
|---|---|---|---|---|
| Bodily Injury Liability | $50,000 | $10,000 medical bills | $10,000 | $0 |
| Property Damage Liability | $25,000 | $8,000 vehicle repair | $8,000 | $0 |
Collision Insurance
Collision insurance covers damage to your own vehicle when you’re involved in an accident, regardless of who is at fault. This coverage applies to collisions with another vehicle or with stationary objects such as trees or guardrails.
While collision insurance is not required by law, it may be required if you are financing or leasing your vehicle. For example, if you finance your car through a bank or credit union, they will typically require you to carry collision insurance until the loan is paid off.
Let’s consider you’re driving in a parking lot and accidentally hit a light pole. The repair costs to your vehicle come to $6,000. If you have collision insurance with a $500 deductible, you will pay the $500 deductible, and your insurance will cover the remaining $5,500.
Example Calculation for Collision Insurance:
- Accident results in $6,000 worth of repairs.
- Deductible: $500
Your insurance covers $5,500, and you pay the $500 deductible.
| Coverage Type | Accident Costs | Deductible | Amount Covered by Insurance | Amount You Pay |
|---|---|---|---|---|
| Collision | $6,000 | $500 | $5,500 | $500 |
Comprehensive Insurance
Comprehensive insurance, sometimes called “other than collision” coverage, covers damage to your vehicle that is not the result of a collision. This includes damages from events such as theft, vandalism, fire, natural disasters, and animal strikes. Like collision coverage, comprehensive insurance is usually required if you are financing or leasing your car.
Suppose you park your car outside, and a tree branch falls on it, causing $2,000 worth of damage. If you have comprehensive coverage with a $200 deductible, your insurance will cover $1,800 after you pay your deductible.
Example Calculation for Comprehensive Insurance:
- Damage caused by falling tree branch: $2,000
- Deductible: $200
Your insurance covers $1,800, and you pay the $200 deductible.
| Coverage Type | Accident Costs | Deductible | Amount Covered by Insurance | Amount You Pay |
|---|---|---|---|---|
| Comprehensive | $2,000 | $200 | $1,800 | $200 |
Uninsured/Underinsured Motorist Coverage
Uninsured/underinsured motorist (UM/UIM) coverage protects you if you are in an accident where the other driver is at fault but either doesn’t have any insurance or doesn’t have enough to cover the full extent of the damage. UM/UIM coverage can help pay for medical bills, lost wages, and pain and suffering, similar to bodily injury liability coverage, and it can also cover property damage.
For instance, if you’re in an accident with another driver who has no insurance or minimal coverage, and your medical bills total $20,000, your UM/UIM coverage can help cover the costs. Suppose you have UM coverage of $50,000. If the at-fault driver has no insurance, your insurance will cover the $20,000 in medical expenses.
Example Calculation for UM/UIM Coverage:
- Medical bills: $20,000
- At-fault driver has no insurance
- UM/UIM coverage: $50,000
Your UM/UIM insurance will cover the $20,000 in medical expenses.
| Coverage Type | Accident Costs | Amount Covered by Insurance | Amount You Pay |
|---|---|---|---|
| Uninsured Motorist (UM) | $20,000 medical bills | $20,000 | $0 |
Comparison of All Four Coverage Types
The following table compares the four major types of auto insurance based on the situations they cover:
| Coverage Type | Covers What? | Required by Law? | Example Scenarios |
|---|---|---|---|
| Liability Insurance | Injuries or damage to others caused by you | Yes (in most states) | At-fault accident causing injury to another driver |
| Collision Insurance | Damage to your vehicle caused by a collision | No (unless financing/leased vehicle) | Crashing into another car or stationary object |
| Comprehensive Insurance | Non-collision damage (theft, vandalism, natural disasters) | No (unless financing/leased vehicle) | Tree branch falling on your vehicle |
| Uninsured/Underinsured Insurance | Injuries and damage caused by a driver with no/insufficient insurance | No | Accident caused by an uninsured or underinsured driver |
Conclusion
As I’ve explained in this article, understanding the four types of auto insurance is crucial for making informed decisions about the protection you need for your vehicle. Whether you’re choosing liability, collision, comprehensive, or uninsured motorist coverage, each type has its own purpose and provides unique benefits.
By evaluating your needs, considering your financial situation, and understanding how each type of insurance works, you can select the right combination of coverages to protect yourself and your vehicle. Remember, insurance policies are not one-size-fits-all, so take the time to review your options and ensure you have the right coverage for your circumstances.
I hope this breakdown of the four main types of auto insurance helps you better understand your options and how each type works. When in doubt, it’s always a good idea to reach out to an insurance agent for advice tailored to your specific situation.
