Why 1-in-4 cars in Bexar County drive uninsured (and what it costs everyone else)

A friend up in Stone Oak got rear-ended on the 1604 frontage last August, driving home from work. Not her fault. The other driver flipped his hazards, mumbled an apology, and handed her a phone number that turned out to belong to a vape shop in Brackenridge. By the time SAPD ran the plates the car had a lapsed registration and no policy on file. Her collision deductible covered the bumper repair, but she paid $1,500 out of pocket before her insurer wrote a single check. Most San Antonio drivers don't know how often this happens here compared to the rest of Texas. The number is worse than people think.

The Bexar 23% number

About 23% of vehicles registered in Bexar County are uninsured, per TxDMV's TexasSure verification database and Texas Comptroller statistical attribution. The Texas statewide rate sits near 14% per the Insurance Information Institute. So a San Antonio driver runs into roughly 64% higher odds, per registered car, that whoever hits them has no policy than a driver in a comparable Texas metro. That's not folklore. That's the statistical attribution carriers use when they price your territory.

The figure is a statistical attribution, not a moral one. The published reasons for why Bexar runs above the state average tend to land in three buckets: parts of the county sit below the Texas median household income, registration patterns in any large urban county skew toward more lapsed and informal-economy vehicles, and Joint Base San Antonio (Lackland, Randolph, Fort Sam Houston) cycles through service members and dependents fast enough that insurance lapses during a PCS move are not rare. None of those describe a person. They describe a registered-vehicle population.

What the math costs everyone else

Here's where the 23% lands on your wallet. UM/UIM — uninsured and underinsured motorist coverage — is what kicks in when the at-fault driver has nothing to pay with. Under Insurance Code Chapter 1952, Texas treats it as a mandatory offer. The carrier has to put it in front of you, and you have to sign a written rejection to skip it. Plenty of San Antonio drivers reject it without reading the form. That's the move that costs them the day a Stone Oak fender-bender turns into a Stone Oak medical bill.

UM/UIM on a typical San Antonio policy runs a small fraction of total premium, usually two figures per year for meaningful limits stacked on top of bodily injury and property damage. The exact number swings by carrier, but the relative cost is small compared to the protection it buys when the other driver has nothing. We won't quote specific carrier filings here. The point is the line item is cheap relative to what it covers, and a Bexar County driver is roughly 64% more exposed to needing it than the statewide baseline driver.

What UM/UIM picks up in a real claim: medical bills above the at-fault driver's (nonexistent) liability limit, lost wages, pain and suffering on a settled injury claim, and property damage the at-fault driver's policy would normally pay if it existed. It does not pay if you cause the wreck. It pays when somebody else causes it and can't make you whole.

The vehicle-theft side

The other piece of the San Antonio picture is theft. SAPD's published vehicle-crime data logged about 19,000 vehicle thefts inside city limits in the 12 months ending May 2024, and NICB's regional vehicle-theft reporting has placed Bexar County near the top of the Texas table year after year. That number matters here for a specific reason. If your parked car gets hit and run by someone who flees, or stolen and then crashed somewhere across town, the coverage that pays for that loss isn't collision and it usually isn't UM. It's comprehensive.

Comprehensive is the line that catches theft, vandalism, hail damage, deer strikes, and the parked-car hit-and-run. At ~19,000 thefts a year, every dollar of comprehensive premium buys more here than it would in El Paso or Lubbock. If you carry liability-only in Bexar County and your car gets stolen out of an H-E-B parking lot off Loop 410, the policy pays zero on the vehicle. Some San Antonio drivers run liability-only on older paid-off cars to save money. That math works until the car gets taken or the hood gets caved in by an uninsured driver who doesn't stop.

Tying the two threads together: the uninsured rate tells you to carry UM/UIM. The theft rate tells you to carry comprehensive. Together they describe why a San Antonio policy needs both lines pulled even when the bottom-line premium looks cheaper than Dallas or Houston.

What to do with this

A few moves worth making before your next San Antonio renewal lands.

First — pull the declarations page and see if UM/UIM is actually on the policy. If it isn't, somebody signed a written rejection at some point. You, or your agent. You can add it back at the next renewal or mid-term. Match the UM/UIM limits to your bodily-injury and property-damage limits. Liability at 100/300/100? UM/UIM at 100/300. A mismatch defeats the point.

Second, check the comprehensive deductible. A $500 deductible in Bexar County is more defensible than the same deductible in a low-theft metro because the claim rate is higher. Some drivers run $1,000 to keep the premium down. Both are reasonable. Liability-only on a car you'd actually miss is the move that goes badly here.

Third, if you're financing or leasing, ask whether gap coverage is on the policy. Lenders sometimes require it, sometimes don't, and the gap between what you owe and what the car is worth on a total loss can be five figures on a newer truck or SUV. A San Antonio driver with a stolen-and-totaled 2023 F-150 still owing $42,000 on the note finds out about the gap question the hard way.

Fourth, ask whether your agent has actually quoted you against multiple carriers in the past 18 months. Carrier appetite for Bexar County risk shifts inside the broader Texas filing cycle. The company that wrote you the best rate in 2024 may not crack the top three for your profile today, because UM/UIM and comprehensive pricing both move independently of liability inside any given carrier's filings.

For local quotes, start on the San Antonio directory page. About 1,800 licensed agencies do business in the Bexar area. Some are single-carrier captives. Some are independents holding ten or more appointments. Talk to at least one captive and one independent. UM/UIM and comprehensive are the two lines worth the most attention on a San Antonio quote, more than anywhere else in Texas. The 23% number is why.
