How Much Coverage Do You Need?

A practical guide to choosing the right liability, collision, and comprehensive coverage.

The insurance industry wants you confused. Here's a clear framework for choosing the right coverage.


The Coverage Confusion Problem

When you buy car insurance, you're bombarded with options:

  • Liability limits (25/50? 100/300? 250/500?)
  • Collision vs. comprehensive
  • Uninsured motorist
  • Medical payments vs. PIP
  • GAP coverage
  • Rental reimbursement
  • Dozens of add-ons

Most people either:

  1. Under-insure to save money (risky)
  2. Over-insure because an agent suggested it (expensive)
  3. Accept the default without understanding it (both)

This guide helps you choose intentionally.


The Six Types of Car Insurance Coverage

1. Liability Insurance (Required)

What it covers: Damage you cause to others—their car, their medical bills, their property.

What it doesn't cover: Your own car or injuries.

How it's written: 100/300/100 means:

  • $100,000 per person for bodily injury
  • $300,000 total per accident for bodily injury
  • $100,000 for property damage

Minimums vary by state:

State ExampleMinimum Required
California15/30/5
Texas30/60/25
New York25/50/10
Florida10/20/10 (property only)

The problem with minimums: They're dangerously low. A serious accident can easily exceed $100,000 in medical bills alone.

Recommended: At least 100/300/100. If you have assets to protect, consider 250/500/250.


2. Collision Coverage (Optional)

What it covers: Damage to your car when you hit something (another car, a tree, a guardrail).

What it doesn't cover: Damage from non-collision events (theft, weather, animals).

Deductible: You choose ($250, $500, $1,000). Higher deductible = lower premium.

When you need it:

  • Newer or more valuable car
  • Financed/leased vehicle (lender requires it)
  • You can't afford to replace the car out of pocket

When you can skip it:

  • Car's value is less than 10x the annual collision premium
  • You have savings to replace the car
  • Car is paid off and not worth much

The math:

  • Car value: $5,000
  • Collision premium: $600/year
  • $5,000 ÷ $600 = 8.3 years to pay the car's value in premiums
  • Consider dropping coverage

3. Comprehensive Coverage (Optional)

What it covers: Damage to your car from non-collision events:

  • Theft
  • Vandalism
  • Weather (hail, flood, falling trees)
  • Fire
  • Animal collisions (hitting a deer)
  • Falling objects

What it doesn't cover: Mechanical breakdowns, normal wear and tear.

Deductible: Typically $250-$1,000.

When you need it:

  • Newer or valuable car
  • Live in area with theft/break-ins
  • Weather risks (hail-prone regions)
  • Financed/leased (required by lender)

Often overlooked: Comprehensive is usually cheap ($100-$300/year) even when collision is expensive. Many people drop collision but keep comprehensive.


4. Uninsured/Underinsured Motorist (UM/UIM)

What it covers: Your injuries and car damage when the at-fault driver:

  • Has no insurance
  • Has insurance but not enough to cover your losses
  • Hits and runs

Why it matters:

  • ~13% of drivers are uninsured nationally
  • In some states, it's over 20%
  • Many insured drivers carry only state minimums

Recommended: Match your liability limits. If you have 100/300 liability, get 100/300 UM/UIM.

Required in: Some states mandate UM/UIM. Others make it optional.


5. Medical Payments / Personal Injury Protection (PIP)

Medical Payments (MedPay):

  • Covers medical bills for you and passengers
  • Regardless of fault
  • Usually $1,000-$10,000 limits
  • Works alongside health insurance

Personal Injury Protection (PIP):

  • Required in no-fault states
  • Covers medical bills, lost wages, essential services
  • Higher limits than MedPay
  • Pays regardless of fault

When it helps:

  • High deductible health plan
  • Want immediate coverage without fault determination
  • Covering passengers who may not have health insurance

Tip: If you have good health insurance, MedPay can be minimal. If you have poor or no health insurance, higher PIP/MedPay is valuable.


6. Add-On Coverages

Rental Reimbursement:

  • Pays for a rental car while yours is being repaired
  • Usually $30-$50/day for 30 days max
  • Costs ~$30-$60/year

Worth it if you can't go without a car.

Roadside Assistance:

  • Towing, jump starts, flat tire help, lockout service
  • Costs ~$10-$30/year

Skip if you have AAA or roadside through your car manufacturer.

GAP Insurance:

  • Covers the "gap" between what you owe and what your car is worth
  • Critical if you're underwater on your loan
  • Usually needed first 2-3 years of ownership

Essential if you put less than 20% down or have a 72+ month loan.


The Coverage Framework

Determine Your Risk Tolerance

Conservative (maximum protection):

  • High liability (250/500 or more)
  • Full collision and comprehensive
  • UM/UIM matching liability
  • MedPay/PIP
  • All add-ons

Moderate (balanced):

  • Solid liability (100/300)
  • Collision and comprehensive with $500-$1,000 deductible
  • UM/UIM matching liability
  • Minimal MedPay
  • Rental coverage only

Aggressive (minimize cost):

  • Higher liability (still protect assets)
  • Drop collision on older cars
  • Keep comprehensive (cheap protection)
  • UM/UIM at lower levels
  • Skip most add-ons

The Asset Protection Rule

If someone sues you after an accident, what can they take?

Your Net WorthRecommended Liability
< $50,000State minimum to 50/100
$50,000-$150,000100/300/100
$150,000-$500,000250/500/250
$500,000+250/500 + umbrella policy

Umbrella insurance adds $1-5 million in liability protection for ~$200-$500/year. Very cost-effective for high-net-worth individuals.

The Car Value Rule

When to carry collision/comprehensive:

Car ValueDeductible + Annual PremiumKeep Coverage?
$25,000+AnyYes
$15,000-$25,000< $1,500Yes
$8,000-$15,000< $1,000Maybe
< $8,000< $500Probably drop
< $4,000AnyDrop it

The 10x rule: If your car is worth less than 10x your annual collision premium, consider dropping collision.


How to Lower Your Premium Without Sacrificing Coverage

Raise Your Deductible

Deductible ChangeTypical Premium Reduction
$250 → $50015-30%
$500 → $1,00015-30%
$1,000 → $2,00010-20%

Only do this if you can afford to pay the deductible after an accident.

Bundle Policies

Combining home/renters + auto typically saves 5-25%.

Ask About Discounts

Discount TypeTypical Savings

Paperless/autopay3-10%
Anti-theft device2-10%
Professional/alumniVaries

Shop Around (Seriously)

Rates vary dramatically between companies—sometimes by 50-100% for the same coverage.

Best practice: Get quotes from 5-7 companies every 1-2 years:

  • Your current insurer
  • Big nationals (GEICO, Progressive, State Farm, Allstate)
  • Regional insurers in your area
  • At least one direct writer (USAA if eligible, Lemonade)

Consider Telematics

Usage-based insurance tracks your driving:

  • Progressive Snapshot
  • Allstate Drivewise
  • State Farm Drive Safe & Save

Good drivers can save 10-30%. Bad drivers may pay more.


State-by-State Considerations

No-Fault States

In no-fault states, your own insurance pays your medical bills regardless of fault:

  • Florida, Michigan, New York, New Jersey, Pennsylvania, Hawaii, Kansas, Kentucky, Massachusetts, Minnesota, North Dakota, Utah

You need: PIP coverage (required) You may not need: As much MedPay

Tort States

In most states (tort states), the at-fault driver's insurance pays:

  • More reason to carry higher UM/UIM (protection from uninsured at-fault drivers)

High Uninsured Driver States

StateUninsured Rate
Mississippi29%
New Mexico26%
Michigan25%
Tennessee23%
California22%

In these states, prioritize UM/UIM coverage.


When to Review Your Coverage

Life changes trigger coverage needs:

EventCoverage Consideration
Bought new carAdd collision/comprehensive
Paid off loanConsider dropping collision
Car now 5+ years oldEvaluate collision value
MovedRates change by location
MarriedMulti-car discount
New teen driverShop around
Retired/work from homeLow-mileage discount
Increased income/assetsRaise liability limits

At minimum, review annually.

The Bottom Line

Insurance isn't one-size-fits-all. The right coverage depends on:

  1. What you're driving - Newer/valuable = more coverage
  2. What you own - More assets = higher liability
  3. Where you live - High uninsured rates = more UM/UIM
  4. Your health insurance - Gaps = more MedPay/PIP
  5. Your risk tolerance - Conservative vs. cost-conscious

The goal isn't the cheapest insurance—it's the right insurance at a fair price.
