Why Uninsured/Underinsured Motorist Coverage Matters After a DUI Crash
A DUI arrest feels like the end of the story. The driver gets pulled over, fails a breath test, and gets booked. Case closed, right?
Not for the person they hit.
The criminal case against a drunk driver and the injury claim that follows a DUI crash run on two completely different tracks. One holds the driver accountable to the state. The other is about who actually pays the hospital bill, the lost wages, and the physical therapy. And here’s the part that catches a lot of accident victims off guard: those two things aren’t connected the way people assume. A conviction doesn’t put money in anyone’s pocket. Recovery depends on insurance, and drivers who get behind the wheel drunk are frequently the same drivers who let their coverage lapse or never bought enough of it in the first place.
That’s where uninsured motorist (UM) and underinsured motorist (UIM) coverage come in, and why it’s worth understanding before you’re the one holding a police report and a stack of medical bills.
The Overlap Between Drunk Driving and No Insurance
There’s no single national study that says “X% of drunk drivers are uninsured,” and any article that hands you a precise number without a source should be read with some skepticism. What’s well documented is the broader trend: a meaningful share of U.S. drivers carry no insurance at all, and a larger share carry only the state minimum, which often isn’t enough to cover a serious crash.
According to the Insurance Research Council (IRC), roughly one in three U.S. drivers was either uninsured or underinsured in 2023, a combined rate that’s climbed about 10 percentage points since 2017. That’s not a drunk-driving statistic specifically, but it’s the backdrop every injury victim is dealing with. If the person who hit you was impaired enough to be arrested, there’s a real chance they were also driving without adequate coverage, whether because of a lapsed policy, a suspended license they ignored, or a habit of cutting corners generally.
Why This Catches People Off Guard
Most drivers assume the other driver’s insurance will simply pay for what happened. In a lot of crashes, it does. But when the at-fault driver has no policy, a canceled policy, or coverage limits too low to cover the damage, that assumption falls apart fast. Suddenly the question isn’t “how much is my claim worth,” it’s “is there any money to collect at all.”
UM and UIM coverage exist to close that gap. UM coverage steps in when the at-fault driver has no insurance or fled the scene. UIM coverage applies when they have insurance, but not enough to cover the full extent of the injury. Both are add-ons to your own auto policy, and both are typically the difference between a claim that gets resolved and one that stalls out entirely.
How the Law Handles This: Arizona, California, and Texas Compared
The rules around UM/UIM coverage vary by state, and a side-by-side look shows both the pattern and the differences.
California
California takes an offer-and-reject approach (Cal. Ins. Code § 11580.2), meaning UM/UIM isn’t automatic here either. As of January 1, 2025, California’s minimum liability limits increased for the first time in over five decades, from $15,000/$30,000/$5,000 up to $30,000 per person, $60,000 per accident, and $15,000 for property damage. That’s a meaningful jump, but UM/UIM limits generally track those same bodily injury numbers, so a driver who only carries the state minimum is still working with a fairly modest cushion if the person who hit them is uninsured entirely.
Arizona
Insurers must offer UM/UIM coverage to every policyholder (A.R.S. § 20-259.01) too, but the driver can reject it in writing. If nobody ever mentions it at the time of purchase, or a driver signs the rejection form without fully understanding what they’re giving up, that protection simply isn’t there when they need it. Arizona’s minimum liability limits are $25,000 per person and $50,000 per accident for bodily injury, and $15,000 for property damage (A.R.S. § 28-4009), which is often not enough to cover serious injuries from a high-speed or impaired-driving crash that’s why uninsured coverage is so crucial.
Texas
Texas flips the default. Under the Texas Insurance Code § 1952.101, insurers are required to include UM/UIM coverage in every auto policy unless the driver rejects it in writing. Functionally, the outcome is similar to Arizona and California: coverage exists, but only if the driver never opted out. Texas’s minimum liability limits currently sit at $30,000 per person, $60,000 per accident, and $25,000 for property damage.
The common thread across all three states is that UM/UIM protection depends on an affirmative choice most drivers don’t remember making. Somewhere in a stack of paperwork, at renewal or at the initial purchase of a policy, there was a line that either added this coverage or waived it. Few people revisit that decision until it’s too late to change it.
What This Means If You’ve Been Hit
If you were injured by a driver who was later arrested for DUI, the criminal case moving forward doesn’t tell you anything about whether you’ll be compensated. Those are separate questions. What actually determines your recovery is:
– Whether the at-fault driver had insurance, and how much. A DUI arrest doesn’t verify this. It’s a separate step your claim will need to establish.
– Whether your own policy includes UM/UIM coverage. This is worth checking now, not after a crash. Pull up your declarations page or call your agent and ask directly whether you have it and at what limits.
– How your state’s offer-and-reject rules apply to your specific policy. Some drivers rejected this coverage years ago without realizing what they were giving up, and don’t find out until they’re filing a claim.
None of this is a substitute for reviewing your specific policy or the facts of a specific crash with someone who can look at both. Every case turns on its own details, and coverage disputes in particular can get complicated when multiple policies or multiple states are involved.
