Four Common Coverage Types Explained

Insurance providers standardize coverage into four main categories, with multiple coverage types within each category. Here's what each one covers and why you might need it:

  1. 1

    Liability Coverage (Legally Required)

    Liability coverage protects you financially when you're at fault in an accident, covering two main components:

    • Bodily injury liability: Pays for others' injuries, including medical costs, lost wages, and legal fees when you're responsible for an accident.
    • Property damage liability: Covers damage to others' vehicles or property. Higher limits cost surprisingly little extra but provide significantly more protection against expensive claims involving multiple vehicles or valuable property.  
    • What the 100/300/100 number mean: The first 100 refers to the bodily injury liability limit per person ($100,000), 300 refers to the bodily injury liability per accident ($300,000), and 100 refers to the property damage liability ($100,000)

    Liability insurance is required in 49 states, New Hampshire is the exception.

    MoneyGeek expert recommendation: Most drivers need 100/300/100.  You can choose less if you have very low assets and are financially constrained or more (e.g. 250/500/250 if you have high assets.

  2. 2

    Full Coverage (Comprehensive and Collision)

    These two coverages protect your own vehicle and are typically presented together as "full coverage" when combined with liability:

    • Collision coverage: Pays to repair or replace your vehicle after crashes with other vehicles or objects, regardless of fault.
    • Comprehensive coverage: Protects against virtually everything else that might damage your car—theft, vandalism, fire, flood, hail, falling trees, and animal strikes.

    These coverages are important for newer vehicles and required for those with loans/leases.  Both coverages require choosing a deductible—the amount you pay before insurance covers the rest. Higher deductibles reduce premiums but increase your out-of-pocket costs when filing claims. For example, increasing your deductible from $500 to $1,000 can save approximately 20-30% on these coverage portions.

    MoneyGeek expert recommendation: Most drivers need comprehensive and collision coverage unless they driver a car valued at less than $3,000 and have the ability to pay for their own repairs for their car.

  3. 3

    Medical coverage options

    These coverages handle injury expenses for you and your passengers:

    • Personal Injury Protection (PIP): Required in "no-fault" states mentioned below, PIP covers medical expenses, lost wages, and sometimes funeral costs regardless of who caused the accident.
    • Medical Payments Coverage: Similar to PIP but typically with fewer benefits and lower limits. Covers medical expenses regardless of fault, often with no deductible.

    These coverages work alongside health insurance but often cover things health insurance doesn't, like dental injuries and funeral costs. 

    MoneyGeek expert recommendation: Unless required in your state (see list below), most drivers don't need this coverage if they have solid health insurance and disability.  You shold add it if you want premium protection.

  4. 4

    Uninsured/Underinsured Motorist Coverage

    This protection activates when you're hit by a driver with insufficient or no insurance:

    • Uninsured motorist bodily injury: Covers your medical costs when hit by an uninsured driver
    • Underinsured motorist bodily injury: Provides additional coverage when the at-fault driver's insurance is insufficient

    The national uninsured driver rate has increased to approximately 12%, with rates exceeding 20% in some states. It's relatively inexpensive coverage that protects against a common risk.

    MoneyGeek expert recommendation: Most drivers need this coverage to protect your car against uninsured drivers.  Its is required in certain states (mentioned below).

How Much Liability Coverage Do You Need?

Determining your liability coverage is the first decision when determining how much insurance you need.

Factors that should drive your decision for how much you need

  • Asset protection: Choose limits high enough to protect your home, savings, and investments
  • Financial situation: Higher income and more assets require higher limits
  • Risk exposure: Consider how much you drive and accident risk
  • Vehicle type: Expensive or heavy vehicles that could cause significant damage warrant higher limits

MONEYGEEK RECOMMENDATION: HOW MUCH LIABILITY DO YOU NEED?

100/300/100 coverage provides good protection for most households. This liability amount costs around $1,200 annually on average when combined with full coverage or about $600 for liability-only policy, but provides 4-10 times more protection than state minimums.  Those with high assets should consider 250/500/250.

Liability Cost by Coverage Amount

Below are the car insurance cost ranges by liability coverage amount when combined with comprehensive and collision (full coverage):

Coverage Level

Typical Annual Cost

State Minimum

Not recommended, unless you are struggling to afford insurance

$500-$700

100/300/100

Most drivers

$1000-$1500

250/500/100+

High-net-worth individuals

$1500+

Do You Need Full Coverage (Comprehensive and Collision)?

The main consideration for comprehensive and collision coverage is your vehicle's value:

  • Required for: Financed/leased vehicles (lender requirement)
  • Probably skip for: Vehicles worth less than $3,000. 10% rule: If annual premiums for comprehensive and collision exceed 10% of your car's value, consider dropping these coverages.
  • Strongly recommended for:
    • Vehicles less than 10 years old or worth more than $3,000-4,000
    • Areas with high theft rates
    • Areas prone to natural disasters or bad weather
    • You wouldn't be able to afford repairs out-of-pocket

Typical Full Coverage Cost: Full coverage (liability + comprehensive + collision) with a $1,000 deductible costs approximately $1,300 annually, compared to about $600 for liability-only coverage

mglogo icon
MONEYGEEK RECOMMENDATION DO YOU NEED FULL COVERAGE?

Most drivers need full coverage and should add collision and comprehensive.  This protects your vehicle. If you drive a low value vehicle, typically below $3,000, and have the money to buy a new car or repair it in the case of a bad accident, you can consider dropping this coverage.

Add-On Policies You May Need or Want

Option add-ons can give you peace of mind and convenience in the case of an accident. These optional coverages enhance your policy for specific situations:

  • Roadside assistance: Covers emergency services like towing, battery jumps, and lockout assistance for $5-15 monthly. The most frequently purchased add-on with 60-70% of insured drivers selecting it.
  • Rental car reimbursement: Pays for a rental vehicle while yours is being repaired after a covered claim, typically costing $5-10 monthly. The second most popular add-on with 50-60% adoption rate.
  • Gap insurance: Covers the difference between your car's value and loan balance if totaled. Required for most leased vehicles and important for financed vehicles that may be worth less than the remaining loan balance. Costs approximately $20-40 annually.
  • New car replacement: Provides a brand-new vehicle of the same make and model if yours is totaled within the first 1-2 years of ownership. Adds 5-10% to comprehensive premiums.
  • OEM parts coverage: Ensures repairs use manufacturer parts rather than aftermarket components. Particularly valuable for luxury vehicles.

MONEYGEEK RECOMMENDATION: WHAT COVERAGE ADD-ONS DO YOU NEED?

With exception of GAP coverage which is required for leased vehicles, adding these coverage types is personal preference.  We recommend new car replacement for cars less than two years old and rental car reimbursement if you don't have alternative transportation and to drive often.

Required Coverage You Need For a Finance or Leased Car

When you finance or lease a vehicle, the lender typically requires certain coverages.  They will ask for proof of coverage.

    bank icon

    When financing a vehicle, lenders typically require:

    1. Full coverage insurance: Includes liability insurance, comprehensive, and collision
    2. Deductible limits: Maximum deductibles ($500 or $1,000)
    3. Continuous coverage: No lapses allowed
    carInsurance icon

    Leasing companies have stricter requirements:

    1. Higher liability limits: Often 100/300/50 or higher
    2. Lower deductibles: Usually maximum of $500
    3. Gap insurance: Usually required
    coins2 icon

    Gap insurance consideration:

    • Required for: Most leased vehicles
    • Strongly recommended for: Loans with less than 20% down payment
    • Most valuable time to buy: In the first 2-3 years when the gap between vehicle value and loan balance is largest due to initial auto depreciation
    • Typically costs: $20-$40 annually

What Deductible Do You Need?

MoneyGeek expert recommendation: You should choose a $500 or $1,000 deductible.  If you choose the higher amount you will save $150-$300 per year, but make sure you have an emergency fund to pay it. 

A deductible is the amount you pay out-of-pocket before insurance coverage pays for a claim:

  • Applies separately to comprehensive and collision claims
  • Paid each time you file a claim
  • Higher deductibles mean lower premiums but more out-of-pocket costs
mglogo icon
MONEYGEEK RECOMMENDATION: CHOOSING A DEDUCTIBLE

You should choose a $500 or $1,000 deductible. If you choose the higher amount you will save $100-$200 per year, but make sure you have an emergency fund to pay it in the case of an at-fault accident.

Minimum Car Insurance Requirements by State

Nearly every state in the U.S. requires minimum liability coverage.  Thirteen states personal injury protection (PIP) to cover medical expenses. Twenty states require uninsured/underinsured motorist coverage, ensuring protection when another driver has no insurance or insufficient coverage.

State
Requirements

Alabama

$25,000 bodily injury liability per person $50,000 bodily injury liability per accident $25,000 property damage liability per accident

*Note: Full coverage insurance, which includes comprehensive and collision coverages, isn’t required by law in any state. However, if you finance or lease your vehicle, your lender or leasing company may require you to maintain full coverage.

States That Require Additional PIP and UM Coverage

Certain states require that you add PIP and UM insurance to your policy to have legal car insurance. These coverages are moderately priced at about $50-$150 annually each, but will add to your policy cost.

  1. 1

    States requiring PIP:

    Personal Injury Protection (PIP) covers medical expenses, lost wages, and essential services for you and your passengers regardless of who caused the accident. PIP is primarily required in no-fault insurance states, where each driver's insurance covers their own injuries regardless of who caused the accident.

    • Delaware, Florida, Hawaii, Kansas, Massachusetts, Michigan, Minnesota, New Jersey, New York, North Dakota, Oregon, Pennsylvania, Utah
  2. 2

    States requiring Uninsured Motorist coverage:

    Uninsured Motorist coverage protects you if you're in an accident with a driver who has no insurance by covering your medical expenses and, in some states, property damage.

    • Connecticut, District of Columbia, Illinois, Kansas, Maine, Maryland, Massachusetts, Minnesota, Missouri, Nebraska, New Hampshire, New Jersey, New York, North Carolina, North Dakota, Oregon, South Carolina, South Dakota, Vermont, Virginia, West Virginia, Wisconsin
  3. 3

    States requiring Underinsured Motorist coverage:

    Underinsured Motorist coverage pays for your expenses when you're hit by a driver whose insurance limits are too low to cover all your damages.

    • Connecticut, Maine, Maryland, Massachusetts, Minnesota, Nebraska, New Jersey, North Carolina, North Dakota, Oregon, South Dakota, Vermont, Virginia, Wisconsin

Do You Need an Umbrella Policy?

An umbrella policy is extra liability coverage that layers on top of your auto (and often home or renters) insurance, paying any lawsuit costs that exceed your underlying limits—typically in $1 million chunks up to $5 million or more.

How Umbrella Polices Work
Your auto policy pays first when you’re liable for injuries or property damage. If a settlement is higher than those limits, the umbrella policy covers the excess—usually starting at $1 million to several million. 

Who Should Get an Umbrella Policy
Anyone with significant assets, high income, or added risk from teen drivers, rental property, or lots of driving should consider an umbrella policy. It adds extra liability protection beyond your auto or home insurance, helping shield your savings and future earnings from costly lawsuits.

When Is State Minimum Car Insurance Coverage Enough?

Though state minimums are less expensive, we strongly recommend higher liability coverage. 

Here is a real life scenario: You have minimum 25/50/25 auto liability coverage and cause an accident that totals a new Range Rover Sport ($100,000 value) and results in $25,000 of medical expenses for the other driver. Your insurance would only cover $25,000 of the vehicle damage and $25,000 of medical costs, leaving you personally responsible for the remaining $75,000 for the vehicle and $25,000 in medical costs. 

You could be sued for this amount plus potential additional damages for pain and suffering or lost wages. This is why higher liability limits provide important protection for your personal assets.
