Regulatory Status: Required in 49 out of 50 states (New Hampshire is the exception)

Liability coverage is a fundamental component of auto insurance policies and is mandated by law in most states. This coverage type addresses costs associated with damage or injury caused to others when the policyholder is determined to be at fault in an accident. Liability coverage does not apply to the policyholder's own injuries or vehicle damage.

Liability coverage consists of two components:

Bodily Injury Liability (BI): Addresses medical expenses, rehabilitation costs, lost wages, and related costs for individuals injured by the policyholder in an accident. In fatal accidents, this component may also address funeral expenses.

Property Damage Liability (PD): Addresses repair or replacement costs for property damaged by the policyholder in an accident. This includes other vehicles, structures, fences, and other property.

Coverage Limit Structure:

Limits are expressed as three numbers (e.g., 50/100/50):

Note: Coverage limits represent the maximum amount the insurer will pay. Costs exceeding the limit are the responsibility of the policyholder.

Regulatory Status: Not required by state law (may be required by lenders or lessors)

Collision coverage addresses repair or replacement costs for the policyholder's vehicle following a collision, regardless of fault determination. This coverage applies whether the vehicle collides with another vehicle, an object, or overturns.

Incidents Addressed by Collision Coverage:

How It Functions: When a claim is filed, the policyholder pays the deductible (commonly ranging from $250 to $1,000), and the insurer pays the remaining repair costs up to the vehicle's actual cash value (ACV). If repair costs exceed the ACV, the vehicle may be declared a "total loss," and payment is based on the vehicle's value minus the deductible.

Deductible Relationship: Higher deductible amounts are associated with lower premium costs, while lower deductible amounts are associated with higher premium costs.

Regulatory Status: Not required by state law (may be required by lenders or lessors)

Comprehensive coverage, sometimes referred to as "other than collision" coverage, addresses damage to the policyholder's vehicle caused by events other than collisions. This coverage type applies to various non-collision incidents.

Incidents Addressed by Comprehensive Coverage:

Glass Coverage: Some policies include separate glass coverage options with different deductible structures for windshield repairs and replacements.

Regulatory Status: Required in approximately 20 states; optional elsewhere

Uninsured/Underinsured Motorist coverage addresses situations where the policyholder is involved in an incident with a driver who lacks insurance (uninsured) or has insufficient coverage to address the costs (underinsured). Industry data indicates that approximately 13% of drivers in the United States do not carry auto insurance.

Two Components of UM/UIM Coverage:

Uninsured Motorist Bodily Injury (UMBI): Addresses medical expenses, lost wages, and related costs for the policyholder and passengers when the at-fault driver has no insurance.

Uninsured Motorist Property Damage (UMPD): Addresses damage to the policyholder's vehicle caused by an uninsured driver. Note: UMPD is not available in all states.

Coverage Limit Options: UM/UIM limits are typically structured similarly to liability limits and may be selected independently or in conjunction with liability coverage, depending on state regulations.

Regulatory Status: Required in 12 "no-fault" states plus Puerto Rico; optional in some other states

Personal Injury Protection, commonly referred to as PIP or "no-fault insurance," addresses medical expenses and other losses for the policyholder and passengers regardless of fault determination. PIP is a mandatory coverage type in states that operate under a no-fault insurance system.

States Requiring PIP: Florida, Hawaii, Kansas, Kentucky, Massachusetts, Michigan, Minnesota, New Jersey, New York, North Dakota, Pennsylvania, and Utah.

What PIP Typically Addresses:

Characteristic of PIP: Unlike liability coverage, PIP claims are processed without waiting for fault determination.

Regulatory Status: Optional in most states

Medical Payments coverage (MedPay) addresses medical expenses for the policyholder and passengers following an accident, regardless of fault. MedPay is similar to PIP but narrower in scope—it addresses medical expenses only, not lost wages or other costs.

Comparison of MedPay and PIP:

Availability: MedPay is commonly available in states that do not require PIP coverage.

Regulatory Status: Optional (may be required by some lease agreements)

Gap insurance (Guaranteed Asset Protection) addresses the difference between the amount owed on a vehicle loan or lease and the vehicle's actual cash value (ACV) if the vehicle is declared a total loss or stolen. This coverage type relates to the phenomenon of vehicle depreciation, as new vehicles typically depreciate 20-30% in the first year of ownership.

Illustrative Scenario:

If a policyholder owes $25,000 on a vehicle loan, but the vehicle's ACV is $20,000 at the time of a total loss, standard coverage would pay $20,000 (the ACV). The policyholder would still owe $5,000 to the lender. Gap insurance addresses this $5,000 difference.

Availability: Gap insurance is offered through auto insurance companies, vehicle dealerships, and lending institutions.

Regulatory Status: Optional add-on coverage

Roadside assistance coverage addresses services related to vehicle breakdowns or situations where a vehicle becomes inoperable. This coverage type is offered as an optional add-on to auto insurance policies.

Services Typically Addressed:

Cost Structure: This coverage is typically priced as an annual add-on, with costs varying by insurer and service limits.

Regulatory Status: Optional add-on coverage

Rental car reimbursement coverage addresses the cost of a rental vehicle while the policyholder's vehicle is undergoing repairs following a covered claim. This coverage type is offered as an optional add-on to auto insurance policies.

Coverage Structure:

Coverage is typically expressed as a daily limit and a maximum total amount (e.g., $30 per day up to $900 total). The coverage period begins when a covered claim is filed and continues until repairs are completed or the coverage limit is reached.

Note: Coverage applies only when the vehicle is being repaired due to a covered claim, not for routine maintenance or mechanical breakdowns (unless covered separately).

Regulatory Status: Optional add-on coverage for newer vehicles

New car replacement coverage is a type of coverage that, in the event of a total loss, provides payment for a new vehicle of the same make and model rather than the depreciated actual cash value of the original vehicle. This coverage type addresses the impact of depreciation on newer vehicles.

Comparison: Standard Coverage vs. New Car Replacement:

With standard coverage, if a one-year-old vehicle originally purchased for $35,000 is totaled, payment is based on the vehicle's current ACV (perhaps $28,000 due to depreciation). With new car replacement coverage, payment would be sufficient to purchase a new equivalent vehicle.

Related Coverage: Some insurers offer "better car replacement" coverage, which provides for replacement with a vehicle one model year newer than the totaled vehicle.

Auto insurance policies consist of multiple coverage types, each addressing specific scenarios. The primary coverage types include liability, collision, comprehensive, uninsured/underinsured motorist, personal injury protection, and medical payments coverage. Additional optional coverages include gap insurance, roadside assistance, rental reimbursement, and new car replacement.

Coverage requirements vary by state, and lenders or lessors may have additional requirements for financed or leased vehicles. Each coverage type has its own structure for limits, deductibles, and conditions as defined in the policy document.
