A DUI makes car insurance harder and more expensive. That's the honest starting point, and this guide won't pretend otherwise. But "harder and more expensive" is not the same as "impossible," and most of what determines how bad it gets is still in your hands. Here's how it actually works and what to do about it.

What happens to your insurance

Two things, usually. First, your rate goes up at renewal, often sharply, because insurers price a DUI as strong evidence of future claims. Second, some carriers decide they don't want the risk at any price and non-renew the policy. That letter feels like a verdict, but it's one company's appetite, not an industry ban. Plenty of insurers actively write policies for drivers with a DUI on their record; they just charge for it.

What you should not do is let coverage lapse while you sort it out. A coverage gap on top of a DUI reads, to the next insurer, like a bigger risk than the DUI alone. And driving uninsured after a DUI can turn a bad year into a much worse one. If your carrier non-renews, line up the next policy before the old one ends.

The SR-22 part

Most states require drivers convicted of a DUI to file an SR-22: a form your insurer submits proving you carry the state's required coverage. The form itself is cheap; the real cost is the high-risk pricing that comes with needing one. If you've been told you need an SR-22, our SR-22 guide covers the mechanics: what it is, how filing works, and what happens if your policy lapses while one is active.

How long it follows you

Each insurer looks back a set number of years when pricing you, and each state limits how long a DUI can count against you. The windows vary (commonly somewhere between three and ten years depending on the state), and the effect fades over time even inside the window. A DUI from last year dominates your price; one from six years ago, with a clean record since, matters far less. There's a date after which this stops being your problem. Every clean year moves you toward it.

Why comparing matters more, not less

Here's the part that surprises people: carriers disagree about high-risk drivers far more than they disagree about everyone else. One company's algorithm treats a DUI as a near-dealbreaker and prices accordingly; another has built its business on exactly this situation. The spread between the best and worst quote for the same post-DUI driver is routinely much wider than for a clean record.

That means the single most expensive mistake after a DUI is taking the first quote, or worse, staying put out of embarrassment and auto-renewing whatever your current carrier offers. You are precisely the shopper comparison was built for. Compare on every renewal while the DUI is on your record; the ranking of carriers can change as it ages.

What else actually helps

  • Keep coverage continuous. It's the cheapest signal of stability you can send, and every insurer checks.
  • Take a state-approved defensive-driving course. In many states it earns a discount, and it never hurts the record you're rebuilding.
  • Consider telematics. Usage-based programs price how you drive now, not just what's on your record. For a genuinely careful driver, that's an advantage. The trade-off: the app is always watching, and hard braking or late-night miles count against you.
  • Revisit your deductibles and coverage levels. The moves in our guide to paying less all still apply; they just matter more when the base rate is high.
  • Wait, cleanly. Time plus a clean record is the one discount that always works. It just isn't fast.

None of this is a trick, and none of it undoes the DUI. It's the playbook for paying what your current risk actually costs instead of what your worst day says it should.
