Is the state minimum liability coverage enough?

Rarely. State minimums were set to ensure basic coverage exists, not to fully protect you in a serious accident. A single hospitalization can easily exceed $100,000. If you cause serious injuries, anything above your liability limit comes out of your pocket.

Do I need full coverage on a paid-off car?

It depends on the car's value and your financial situation. If the car is worth less than $5,000–$8,000 and you could replace it without financial strain, dropping collision and comprehensive may make sense. If you couldn't afford to replace the car out of pocket, keep full coverage.

How do I calculate how much liability coverage I need?

A common approach: match your liability limits to your net worth. If you own a home worth $300,000, carry at least 100/300/100. The logic is that someone who sues you could go after assets above and beyond your insurance limit.

What is an umbrella policy and do I need one?

An umbrella policy provides additional liability coverage above your auto and home limits — typically starting at $1 million. It's generally inexpensive ($150–$300/year) and valuable for homeowners or drivers with significant assets.

How Much Car Insurance Coverage Do You Actually Need?

June 29, 2026

Start with your state's requirements

Every state sets a floor for how much liability coverage you must carry. These minimums let you legally register and drive a vehicle, but they're rarely sufficient for a serious accident.

See State Rules to find your state's exact minimums.

Choosing liability limits

Liability protects your financial assets if you injure someone or damage their property. The right amount depends on what you could lose in a lawsuit.

If your net worth is...	Consider liability limits of...
Under $50,000	At least 50/100/50
$50,000–$200,000	100/300/100
Over $200,000	250/500/100 or higher; consider umbrella

Higher limits cost less than most people expect. The jump from 25/50/25 to 100/300/100 typically adds $50–$150 per year to your premium.

Physical damage coverage: collision and comprehensive

Whether to carry collision and comprehensive depends primarily on your vehicle's value.

Keep collision and comprehensive if:

You have an auto loan or lease (lender will require it)
Your vehicle is worth more than $10,000–$15,000
You couldn't afford to replace the vehicle without insurance proceeds

Consider dropping them if:

Your vehicle is worth under $5,000–$8,000
Your annual premium for both exceeds 10% of the car's value
You have savings to replace the car without insurance

Medical coverage

If your health insurance has high deductibles or gaps, consider adding Medical Payments (MedPay) or PIP for quick coverage of medical expenses after an accident.

Uninsured motorist coverage

With about 1 in 8 drivers uninsured nationwide, uninsured motorist (UM) coverage is a high-value protection at low cost. Many experts recommend matching your UM limits to your liability limits.

A practical coverage checklist

Liability: at least 100/300/100 for most drivers with any assets
Collision and comprehensive: required if financed; evaluate for owned vehicles based on value
UM/UIM: match to liability limits
MedPay or PIP: based on your health insurance coverage
Gap: needed if loan balance exceeds vehicle value
