Ask Deandra: How Much Will a DWI Raise My Car Insurance?

Here is the longer answer, including why insurers price it this way and what you can do about it.

Why Insurers Treat a DWI So Harshly

Auto insurers price risk using actuarial data, not moral judgment, and their data shows that a DWI conviction correlates strongly with future claims. Many carriers weight a DWI more heavily than an at-fault accident or a string of speeding tickets, because it signals a pattern of risk rather than a single lapse in judgment. That is why the increase tends to be larger and longer-lasting than what follows most other violations.

What the Increase Actually Looks Like

• Premium roughly doubling. It is common for drivers to see their six-month or annual premium increase by 80 to 100 percent or more, though the exact figure depends heavily on the carrier, the driver’s prior record, and the county.
• Non-renewal. Some standard insurers simply decline to renew a policy after a DWI conviction, regardless of how long the driver has been with that company.
• Forced move to nonstandard carriers. Drivers who lose standard coverage often end up with a nonstandard insurer that specializes in high-risk policies, typically at a materially higher rate than standard carriers charge even a driver with the same DWI on record.
• SR-22 filing on top of the higher premium. If your license action requires an SR-22, that filing rides on top of the already-elevated premium. The SR-22 fee itself is small; it is the underlying premium that does the damage.

How Long the Increase Lasts

Most insurers use a three to five year lookback window when pricing a renewal, meaning the DWI stays visible to your carrier’s underwriting even after any court-ordered obligations, such as probation or an ignition interlock requirement, have ended. Some drivers see gradual improvement each renewal as the conviction ages within that window, while others see little change until it drops out of the lookback period entirely. Either way, this is why the insurance cost of a DWI is described as the one that outlasts everything else on the list. Court fines and SR-22 filings are finite. The insurance premium increase is not, until enough years pass.

Does It Matter Whether the Case Ends in a Conviction or a Deferred Adjudication?

Insurers generally rely on your driving record and any conviction reported to DPS, so a case resolved through deferred adjudication that avoids a formal DWI conviction can, in some circumstances, avoid the same insurance reporting that a conviction triggers. This is highly fact-specific and depends on how the case is ultimately resolved and what gets reported. It is one of several reasons the outcome of the underlying criminal case, not just the license suspension, matters directly to your long-term insurance cost, and it is a conversation worth having with your attorney before deciding how to resolve the case.

What You Can Actually Do About the Cost

• Shop every renewal. Rates for the same driver vary significantly across carriers, so getting quotes at every renewal, not just the first one, is the most direct way to control the cost while the DWI is still in your lookback window.
• Ask about high-risk specialists. Some insurers specialize in high-risk drivers and price more competitively for that specific population than a standard carrier forced to write a policy it would rather not.
• Keep every other mark off your record. A second violation, even a minor one, while carrying a DWI on your record compounds pricing in a way it would not for a driver without that history, so a clean record going forward matters more than usual during this window.
• Understand how the criminal case resolves. Whether the case ends in a conviction, a reduction, or a dismissal can affect what gets reported and, in turn, what an insurer sees when pricing your policy.
