"Full Coverage" Is Not a Number

Walk into any conversation about car insurance and somebody will say, with the confidence of a person reading a weather report, "Oh, I have full coverage." If you ask them what their bodily injury limits are, they'll look at you like you asked what kind of fuel their car runs on in metric units.

This is not their fault. The phrase "full coverage" is everywhere. Lenders use it. Friends use it. Some agents use it. The problem is that it doesn't mean anything. Or rather: it means whatever the person saying it wants it to mean, which is functionally the same as meaning nothing at all.

If you're going to be honest with yourself about whether you're protected, you have to ditch the phrase. What follows is the vocabulary that actually matters — the words that, when you say them out loud, describe a real number, a real coverage, and a real outcome.

What "full coverage" usually means (in practice)

When someone says they have full coverage, they almost always mean one specific thing: that they have collision and comprehensive coverage on their car, in addition to the liability coverage Texas requires.

That's it. That's the whole phrase.

It tells you nothing about how much liability they carry. Nothing about whether they have uninsured motorist coverage. Nothing about deductibles, rental reimbursement, gap coverage, or umbrella protection. It tells you that if they hit a tree, the insurance will probably help fix their car. That's the entire content of the phrase "full coverage."

Most people who think they have "full coverage" are walking around with the Texas state minimum on liability — $30,000 per person, $60,000 per accident, $25,000 for property damage. They don't know it. They've never asked.

The four numbers that actually describe your auto policy

Here's what to ask for instead. When you call your agent — or look at your declarations page, which is the document we'll cover in another piece — these are the four numbers that tell you what you actually have.

1. Bodily Injury Liability (per person / per accident)

Written like this: $100,000 / $300,000.

The first number is the maximum your insurance will pay for injuries to one person you hurt in an accident you caused. The second number is the maximum it will pay across everyone hurt in that accident, combined.

Texas state minimum is 30/60. The most common middle-ground policies are 100/300. Higher earners and homeowners often run 250/500 or higher. The right number is the one that comfortably covers your assets and earning potential — because once your policy taps out, the gap becomes a problem someone else has to solve.

2. Property Damage Liability

One number, usually written as $25,000 or $50,000 or $100,000.

This is what your insurance pays to fix or replace the things you damaged in an accident — somebody's car, fence, mailbox, garage door, lamppost. Texas minimum is $25,000. That number was written into the law in 1981. The average new car transaction price in 2024 was over $48,000. You do the math.

3. Uninsured / Underinsured Motorist Coverage (UM/UIM)

Written like this: $100,000 / $300,000 — same per-person / per-accident structure as bodily injury.

This is the most underrated coverage in personal auto insurance. About one in eight U.S. drivers has no insurance at all. Many more carry the absolute minimum. UM/UIM is the coverage that pays your medical bills, lost wages, and pain and suffering when somebody else hits you and either doesn't have insurance or doesn't have enough.

Texas requires insurance companies to offer it. They don't require you to take it. You can decline it in writing — and a lot of people do, usually without realizing what they're declining.

One important Texas-specific rule: your UM/UIM limits cannot exceed your bodily injury liability limits. If you carry 100/300 BI, the most UM/UIM the carrier can write is 100/300. You can carry less, but you cannot carry more. The practical takeaway: if you want better protection from other drivers, you generally have to raise your liability limits first. Most agents who know what they're doing will recommend matching the two — same number on both sides.

4. Deductibles (collision and comprehensive)

Two numbers, usually $500 or $1,000, sometimes higher.

These are what you pay out of pocket before insurance kicks in to fix your own car. Collision is for crashes. Comprehensive is for everything else — hail, theft, a deer, a tree branch, a flood. A higher deductible lowers your premium but raises your exposure on a bad day. The right answer here usually depends on whether you have an emergency fund and how much you drive.

The phrase to use instead

So when somebody asks you what coverage you have, the answer that means something sounds like this:

"I'm at 100/300/100 with matching 100/300 UM/UIM and $500 deductibles."

That's a sentence with content. It tells another agent — or anyone who knows what they're listening for — exactly what your policy does. It also tells you something, every time you say it. It makes the abstract concrete.

If you don't know your numbers off the top of your head, that's not a character flaw. Most people don't. The fix takes about ten minutes: pull up your declarations page (it's on the carrier's app, or in the welcome packet they sent when you renewed), find the four numbers above, and write them somewhere you'll see them.

What "full coverage" leaves out entirely

Even if we generously interpret "full coverage" as the highest possible auto policy, it still leaves out three products that matter for most homeowners and parents:

• Homeowners or renters insurance liability limits. Most homeowners policies include $100,000 to $300,000 of personal liability — for things that happen on your property or things you do that aren't auto-related. Same conversation: that number deserves to be looked at.
• Umbrella coverage. A separate policy that adds $1 million or more of liability protection on top of your auto and home limits. Costs are usually in the $200–$500/year range for $1M of coverage. It exists for exactly the situation where your underlying limits aren't enough.
• Coverage on the people in your life who drive your cars. Teenage drivers, household members, the friend who borrows it once a month. There are policy mechanics here that deserve a whole separate conversation.

None of that is captured by "full coverage." None of it.

The takeaway

If you take one thing from this piece: retire the phrase. Not because it's harmful — because it's hollow. It gives you a feeling of being protected without a specific commitment to what that protection actually is. And insurance is a numbers business. The numbers either match your life or they don't, and the only way to know is to look.

If you don't know your numbers, ask your agent. If your agent can't tell you in plain English, that's information too.
