Same DUI, Two Quotes: 7 Underwriting Factors A-LA Agents See Drive the Spread

In a single week this past quarter, two drivers walked into our Buckner Boulevard office in southeast Dallas. Both had the same headline profile: a single DUI conviction 14 months ago, SR-22 already required by DPS, no second strike on the file. Both wanted the same coverage tier — full coverage at 100/300/100 bodily injury/property damage limits, $1,000 collision and comprehensive deductible. We ran both files across our full panel of 35+ carriers, and one specific carrier on that panel — the one whose rate algorithm I have spent the most time learning over the past three years — came back with two completely different numbers.

Driver A: $215/month. Driver B: $89/month. Same product, same carrier, same coverage tier, same DUI category in the carrier's risk-class table. A 2.4x spread on what most consumers would assume is the same risk profile.

When a driver gets a quote like Driver A's and decides "DUI insurance is just expensive," they are leaving real money on the counter. The spread is not random. The carrier is not arbitrary. The seven factors below are what we use to explain the difference to clients in plain English, and three of them are things a driver can actually move inside 30 days.

This is not a theoretical post. The composite below reflects what our agents actually see across our 14 DFW offices when we run DUI files every business day. The numbers vary by carrier, by month, and by which underwriter is on the file, but the seven factors are stable and the relative ranking holds week over week.

The single biggest binary flag we see on the counter is the BAC reading and whether the offense was charged as "aggravated DWI" under Texas Penal Code §49.04(d). The standard DWI threshold in Texas is a BAC of .08. If the BAC came back .15 or higher, the offense is reclassified as a Class A misdemeanor instead of Class B, and that reclassification follows the driver onto the MVR and into the carrier's rating system.

In our experience the spread between a .08–.14 DUI and a .15+ aggravated DWI on the same carrier, same tier, same everything else is typically 40–80% on the monthly premium. Most carriers on our panel run an aggravated-DWI surcharge multiplier that is roughly double the standard DWI multiplier. Driver A in our Buckner pair had a .17 BAC; Driver B had a .09. That single line on the DPS abstract was the largest contributor to the spread.

When a driver asks us "can you re-shop this," the first question we ask is the BAC. If it was below .15, we know we have room to move. If it was .15 or higher, we know the floor is higher and we set the expectation up front rather than promising a number we can't deliver.

Texas operates under implied-consent law, codified in Texas Transportation Code §724. When a driver is stopped on suspicion of DWI, refusing the breath or blood test triggers an automatic 180-day Administrative License Revocation (ALR) suspension on a first refusal. By contrast, failing the test — actually blowing over the limit — triggers a 90-day suspension on a first failure under the same statute. The refusal suspension is roughly double.

Carriers see the longer ALR period on the DPS record and most of them extend the SR-22 carry-period accordingly. Some carriers also flag refusal separately in their rating system as a behavioral risk indicator, on the theory that a refusal correlates with a higher actual BAC than the post-arrest blood draw eventually showed. Our agents see drivers who refused pay roughly 15–30% more than drivers with a similar BAC profile who blew at the scene, on the same carrier, same tier.

Driver A in our Buckner pair had refused. Driver B had blown a .09. Driver A's refusal compounded with the .17 reading to push the carrier into its highest DUI surcharge band. Refusal is locked once it's on the file, but knowing whether the file shows a refusal helps us know which carriers on our panel will quote it most aggressively.

Carriers don't score a DUI in isolation. They score it against the three-to-five-year MVR window behind it. The DUI is the headline, but if the file also shows a speeding 20-plus, a prior at-fault, or a failure-to-maintain-financial-responsibility within the look-back, the surcharge stacks.

In our agent-floor experience, a driver with a clean MVR for the three years before the DUI quotes roughly 20–35% lower than a driver with one or more prior violations on the same DUI. The carrier reads a clean prior MVR as "one-time mistake" rather than "pattern of risk," and that single distinction moves a quote more than almost anything else on the file.

Driver A's MVR showed a prior speeding 22-over from 28 months before the DUI and an at-fault from 41 months before. Driver B's MVR was clean for the full five-year window before the DUI — no tickets, no claims, nothing. Even with the DUI on the file, Driver B's MVR read as essentially a single-incident profile, and the carrier's tier table rewarded that.

When a client asks us how to lower their DUI quote, the MVR depth is the factor we cannot move — it's already on the abstract. But it's the factor we explain most often because clients usually don't realize how heavily their pre-DUI history is being weighed.

Carriers rate residence stability as a proxy for overall risk profile. A driver who has lived at the same ZIP code for five or more years quotes consistently lower than a driver who moved within the last 12 months — same DUI, same everything else. The NAIC Auto Insurance Report documents residence stability as one of the recognized rating factors carriers use across all lines of personal auto, not just DUI files.

In our offices we see a typical spread of 8–15% on the same DUI profile between a long-term DFW resident and a recent mover. Driver B in our Buckner pair had lived in the same 75217 ZIP for nine years. Driver A had moved twice in the previous 18 months — one address in Fort Worth, then Mesquite, then Dallas. The carrier's algorithm read that movement pattern as elevated risk and adjusted accordingly.

A valid Texas driver license, current address on the DL matching the policy address, and a documented multi-year residence at that address all consistently quote at the lower end of the carrier's band. We do not advise drivers on ID matters beyond confirming the DL is current and the addresses align — but we do confirm it on every file before binding, because a mismatch can trigger a re-rate after the policy issues.

On a liability-only SR-22 filing, vehicle choice doesn't move the quote much — the carrier is mostly rating the driver. But on full coverage with comp and collision, vehicle age and value drive a significant portion of the premium independently of the DUI surcharge.

Driver A drove a 2022 model-year crossover with a comprehensive replacement value north of $32,000. Driver B drove a 2014 sedan worth roughly $8,500. Even before the DUI surcharge math, the physical-damage portion of Driver A's premium was roughly double Driver B's on the same 100/300/100 + $1,000-deductible structure. Layer the DUI surcharge multiplier on top of that already-higher physical-damage base, and the spread compounds.

When a DUI-flagged driver shopping full coverage walks into our Mansfield Highway office and asks "why is my quote so high," the first thing we look at after the BAC is the vehicle. A 2014–2017 model-year sedan with a moderate replacement value almost always quotes lower than a 2022+ crossover or truck on the same driver profile. We don't recommend changing vehicles to get a quote — but if a client is already planning to swap vehicles, we'll mention it.

If full coverage is not legally required by a lienholder, we also run a liability-only + SR-22 quote so the driver sees the option. For a $215/mo full coverage quote, a liability-only SR-22 quote on the same driver can land closer to $115/mo on the same carrier.

Carriers look at where the driver is in the DPS reinstatement process. A driver who has paid all fines, paid the reinstatement fee under Texas Transportation Code §601.231, completed the court-mandated and DPS-required programs, resolved the ALR, and is either fully reinstated or holding a valid occupational license consistently quotes lower than a driver who is mid-process.

Driver B had completed every step: ALR resolved, all fines paid, DPS reinstatement fee paid, defensive driving course completed voluntarily on top of the court-ordered class. The DPS record showed "eligible" status with a current valid Texas DL. Driver A had not yet paid the second-year of the Driver Responsibility Program surcharge (note: Texas eliminated DRP for new convictions on Sept 1, 2019, but legacy installment-plan surcharges from older convictions are still on some files), and the DPS record showed an occupational license rather than full reinstatement.

In our agency-floor experience, the "fully reinstated" signal vs "occupational only" signal is worth roughly 10–18% on the same DUI profile, same carrier. The carrier reads full reinstatement as "the driver has demonstrably completed the consequences," and the rate reflects it.

This factor is partially addressable in 30 days. A driver who has not completed defensive driving can complete it. A driver who has not paid an outstanding fine can pay it. A driver who is eligible for ALR resolution can pursue it. We don't handle the DPS side directly, but we do tell every walk-in DUI client that finishing the reinstatement checklist before the next renewal will visibly move the quote.

The last factor — and the easiest one to fix in 30 days going forward — is coverage continuity. Carriers look at whether the driver had continuous insurance coverage before the DUI and whether there has been a lapse since. A clean continuity history (active policy at the time of the DUI, active policy maintained since) reads as a different risk tier than a lapsed-coverage profile.

Driver B had been insured continuously for seven years before the DUI on a prior carrier, picked up a new policy within 48 hours of the DUI conviction, and had no lapse since. Driver A had a 31-day lapse before the DUI (policy cancelled for non-pay, never reinstated) and a second 47-day lapse after the DUI before walking into our office. Two lapses on the same file, both visible to the carrier through Texas's electronic verification system.

The lapse-related portion of Driver A's quote was roughly $22 of the $215 monthly premium. Not the biggest factor in the spread, but a real and avoidable one. Any future lapse compounds: a third lapse would have moved the carrier's rating tier down again, and at some point the carrier stops quoting that profile at all.

This is why we tell every DUI walk-in: bind the policy the same day. Don't go home to "think about it" for a week. Every day of additional lapse on the file makes the next quote slightly worse, and the rate you lock today is the rate the carrier reports to DPS for SR-22 compliance. A-LA can bind a policy in under an hour at any of our 14 DFW offices, including same-day SR-22 electronic filing to DPS.

Of the seven factors above, four are essentially locked once they land on the DPS abstract: BAC level, aggravation status, refusal-vs-blow, and the prior 3–5 year MVR history. A driver who walks into our office with a $215/mo quote driven mostly by those four factors should not expect us to find them an $89/mo quote on the same coverage. We will run the panel and find the best number the market will give, but we won't promise a number we can't deliver.

Three of the seven, however, are addressable inside 30 days, and we have seen them collectively move quotes 15–25% on the same driver:

• Complete DPS reinstatement. Pay all outstanding fines, pay the reinstatement fee under Transportation Code §601.231, resolve the ALR, and complete any DPS-required programs. Get the DPS record updated to "eligible" or fully reinstated rather than "occupational only."
• Complete voluntary defensive driving. A Texas DPS-approved defensive driving course completed voluntarily (not court-ordered for a ticket) signals to carriers that the driver is taking the reinstatement process seriously. Many carriers also apply a 5–10% premium discount independent of the DUI rating.
• Lock coverage continuity going forward. Bind a policy the same day, pay on time every month, never let it lapse. Each renewal with zero lapse on the file moves the driver slightly down the carrier's risk tier table.

Drivers should also start shopping the market again at month 22 of the SR-22 carry period, not at month 24, so the new quote is in hand before the renewal notice arrives. Texas SR-22 carry is two years from the date of conviction under most carriers' interpretation of Transportation Code §601.072, and the post-SR-22 shopping window is where our agents see the largest premium drops.
