Car Insurance Coverage Limits: What the Numbers on Your Policy Actually Mean

What Those Slash Numbers Actually Mean

If you've ever looked at your auto insurance policy and seen something like 100/300/100, you're not alone in wondering what it means. These three numbers represent your liability coverage limits — the maximum dollar amounts your insurer will pay out under specific circumstances after an at-fault accident.

Here's how to read them:

• First number (100): The maximum your insurer will pay for bodily injury to one person in a single accident — in this case, $100,000.
• Second number (300): The maximum for bodily injury to all people injured in a single accident — here, $300,000 total.
• Third number (100): The maximum for property damage you cause in a single accident — $100,000.

These are per-accident caps, not annual limits. If costs exceed your limits, you may be personally responsible for the difference. That's why choosing limits that reflect your actual financial exposure matters.

Collision and Comprehensive: How Deductibles Work Instead

Liability coverage uses split limits as described above, but collision and comprehensive coverage work differently — they use a deductible rather than a per-person or per-accident cap.

Your deductible is the amount you agree to pay out of pocket before your insurer covers the rest. Common deductible amounts are $250, $500, or $1,000. A higher deductible generally lowers your premium but increases what you pay when you file a claim.

After your deductible is met, your insurer pays up to the actual cash value (ACV) of your vehicle — meaning its current market value, not what you originally paid. This distinction surprises many drivers at claim time.

For example: if your car is worth $12,000 and you have a $500 deductible, your insurer would pay a maximum of $11,500 for a covered total loss.

To avoid surprises, review common misconceptions about what car insurance pays for before you need to file a claim.

How to Decide If Your Current Limits Are Enough

State minimum liability limits are legally required, but they're often lower than what a serious accident actually costs. Medical bills, lost wages, and legal fees can add up quickly — and if a judgment against you exceeds your policy limits, your personal assets could be at risk.

A few factors worth weighing when reviewing your limits:

• Your assets: The more you own — savings, property, retirement accounts — the more exposure you have if you're sued after an at-fault accident.
• Your driving environment: Frequent highway driving or dense urban areas may carry higher accident risk.
• Your vehicle's value: If your car is older and worth less, carrying collision and comprehensive coverage may not be cost-effective once the premium approaches the ACV.
