Understanding How Florida Treats DUI Convictions from Other States—and Why Your Defense Strategy Must Account for It

When clients come to me with DUI charges, many are surprised to learn that a DUI conviction from another state—sometimes from many years ago—can come back to impact their Florida case. Florida law allows prosecutors to consider out-of-state DUI convictions when determining whether you’re facing a first, second, third, or even felony DUI. That single fact can drastically increase your exposure to jail time, fines, and license suspension. If you’ve been charged with DUI in Florida and have any kind of prior DUI conviction, even from another state, you need to understand exactly how this could affect your case.

Let me explain what the law says, what options may be available, and how I’ve helped clients in situations like yours.

Florida Law on Out-of-State DUI Convictions

Under Florida Statutes Section 316.193, DUI penalties increase based on prior convictions. What many people miss is how Florida courts define a "prior conviction."

Section 316.193(6)(b) states:

"For the purposes of this subsection, a conviction for a violation of s. 316.193, or a similar offense of another jurisdiction, is considered a prior conviction."

That phrase, “or a similar offense of another jurisdiction,” is where out-of-state DUIs become relevant. Florida courts have interpreted this to mean that if you were convicted in another state for conduct that would have also violated Florida’s DUI laws, the state can count it as a prior conviction for sentencing purposes.

This isn’t just legal theory. Prosecutors use national databases, including the National Driver Register (NDR) and Commercial Driver’s License Information System (CDLIS), to search for priors in other states. If they find something on your record, you can bet it will be used to push for enhanced penalties unless your attorney successfully challenges it.

Real Case Example: Reduced Penalty After Challenging Prior DUI

A few years ago, I represented a client who had been arrested for DUI in Naples, Florida. The prosecutor claimed it was his third DUI, because he had two previous convictions—one in Alabama from 11 years ago, and one in Georgia from 8 years prior. They were seeking felony charges.

I carefully reviewed both out-of-state cases. We found that the Alabama case had resulted in a “youthful offender” adjudication that, under Alabama law, didn’t count as a formal conviction. The Georgia case involved a plea to a reckless driving charge, not DUI. We filed a motion to strike both priors from consideration.

The judge agreed that neither of the prior cases qualified as a DUI “conviction” under Florida law. As a result, the prosecutor had to proceed as if it was my client’s first DUI offense. He avoided jail time entirely and kept his license with only a six-month hardship restriction.

This is why having an experienced DUI defense lawyer who knows how to challenge the use of out-of-state priors is so critical.

How Prosecutors Determine Whether a Prior Counts in Florida

The key is whether the prior offense is “substantially similar” to a Florida DUI under § 316.193. Here’s what they look at:

  • Was the out-of-state conviction for driving or being in actual physical control of a vehicle?

  • Did the other state require impairment by alcohol or drugs?

  • Did the BAC threshold meet Florida’s 0.08% standard?

If the other state’s statute is broader or different in a meaningful way, we can often argue it should not be used to enhance a Florida sentence. I’ve successfully blocked priors from states like North Carolina, South Carolina, and Pennsylvania because their laws either didn’t require proof of impairment or allowed DUI convictions based on lesser evidence than Florida law does.

Florida appellate courts have also ruled that the state has the burden to prove that the out-of-state statute is substantially similar. If the prosecution can’t meet that burden, the prior shouldn’t count.

Penalties if the Prior Is Counted

If your out-of-state DUI does count, here’s how penalties can escalate under Florida Statute § 316.193:

  • Second DUI (within 5 years): Mandatory 10 days in jail, 5-year license revocation, ignition interlock device, and a fine of up to $2,000.

  • Third DUI (within 10 years): Third-degree felony, up to 5 years in prison, 10-year license revocation, 90 days of vehicle impoundment.

  • Fourth DUI (regardless of timeframe): Automatic felony with minimum prison exposure and permanent license revocation.

But remember, the state must first prove that the out-of-state offense matches Florida’s DUI statute. That’s where your defense lawyer can make the biggest impact.

Defenses to Out-of-State DUI Priors

There are several valid defense strategies I’ve used to prevent Florida courts from counting an out-of-state DUI as a prior offense:

  1. Non-Equivalent Statutes: If the statute in the other state is broader or uses different legal elements, I can argue that it’s not substantially similar and should not qualify under Florida’s law.

  2. Incomplete Records: Prosecutors often rely on summary reports or NCIC printouts. Without certified court records showing the exact plea and outcome, we may be able to keep the prior out.

  3. Youthful Offender or Deferred Adjudication: Some states offer non-conviction dispositions. If the prior case didn’t result in a formal conviction, I can argue it doesn’t count.

  4. Challenge the Identity: If the record doesn’t clearly link you to the prior offense—such as a different middle name or date of birth—we can challenge the evidence tying that DUI to you.

  5. Constitutional Violations in the Prior Case: If your rights were violated in the prior DUI, such as lack of counsel or an invalid plea, that conviction might be inadmissible for enhancement purposes.

Why You Need a Private DUI Defense Attorney

Public defenders and overworked court-appointed lawyers often lack the time or resources to research and challenge priors from other states. A private attorney can dig into the details and file motions that take hours of legal work—effort that can mean the difference between a misdemeanor and a felony.

I’ve seen clients show up to court assuming a prior DUI from another state was no big deal, only to find themselves facing prison time. Don’t make that mistake. Let me examine the details, pull the original court records, and push back where the state overreaches.

Consequences Beyond the Courtroom

If Florida treats your out-of-state DUI as a prior, the consequences go beyond jail time or fines. You could also face:

  • Lengthy license suspension

  • Mandatory ignition interlock device

  • Sky-high insurance premiums

  • Loss of commercial driving privileges

  • Barriers to employment or housing

If you’re not a U.S. citizen, DUI convictions can trigger immigration consequences. Prior offenses increase your vulnerability to deportation or inadmissibility, particularly if charged as a felony. These collateral consequences are rarely explained in court. My job is to help you understand them—and help you avoid them.

Fighting the Current DUI Charge

In many cases, we can attack the DUI charge itself. Just because you were arrested doesn’t mean you’re guilty. I regularly challenge:

  • Lack of probable cause for the stop

  • Flawed field sobriety tests

  • Inaccurate breath or blood tests

  • Improper police procedures

  • Violations of your right to counsel

When we weaken the state’s current case and neutralize their attempt to enhance the charge with out-of-state priors, we can negotiate better outcomes—or get the case dismissed.

Final Thoughts on Defending Multi-State DUI Issues

A DUI charge in Florida doesn’t exist in a vacuum. Prior offenses from any state could follow you here, but that doesn’t mean you’re without options. Every case needs careful review. If you have a prior DUI—or even think you might—get a skilled defense lawyer involved immediately. The state is building a case. You need to build your defense just as aggressively.

FAQs About Out-of-State DUIs in Florida (600 words)

Can Florida use a DUI from another state to increase my penalties?
Yes, Florida law allows prosecutors to use DUI convictions from other states to enhance your penalties. If the offense in the other state is similar to Florida’s DUI law, it can be treated as a prior conviction, making your current charge more serious. This can raise a misdemeanor to a felony, increase fines, and impose mandatory jail time. However, the burden is on the state to prove that your out-of-state conviction meets Florida’s legal standard.

What if my prior DUI happened more than 10 years ago?
Time matters in DUI sentencing. Florida treats second DUIs within 5 years and third DUIs within 10 years much more harshly. If your prior DUI is older, it may still count as a prior for some purposes, but it won’t automatically trigger mandatory minimums. Even if it’s older than 10 years, prosecutors may still try to use it. A knowledgeable attorney can work to minimize its impact.

What if I was never convicted, just arrested for DUI in another state?
An arrest by itself doesn’t count. Florida only considers convictions or pleas of guilty or no contest. If the prior case was dismissed, dropped, or resolved without a conviction—like through a deferred prosecution or diversion program—it generally shouldn’t count. However, the details matter, and some out-of-state programs are treated differently under Florida law.

Can I argue that the other state’s DUI law isn’t similar enough?
Yes. One of the strongest defenses we use is arguing that the statute in the other state isn’t substantially similar to Florida’s DUI law. For example, some states allow DUI convictions for sitting in a parked car while drunk, even without intent to drive. Florida requires “actual physical control” and proof of impairment. If the legal definitions don’t match up closely, we can argue that the prior shouldn’t be used against you.

Will an out-of-state DUI affect my Florida driver’s license?
Yes, it can. Florida’s Department of Highway Safety and Motor Vehicles shares information with other states. If another state reports a DUI conviction to Florida, the Florida DMV can suspend your license or require ignition interlock, depending on your history. These administrative penalties can apply even if you’re not criminally charged again. That’s why it’s important to contest out-of-state reports that may not be valid.

Can a lawyer help remove a prior DUI from my record?
In some situations, yes. While you can’t expunge a DUI conviction in Florida, we can sometimes reopen out-of-state cases or seek to downgrade prior charges through post-conviction relief. More commonly, we challenge the state’s ability to use the prior conviction to enhance your sentence. That means reviewing the other state’s law, requesting the full court file, and filing legal motions to exclude it.

What should I do if I’m unsure whether a prior DUI will count?
Don’t guess. Even one prior conviction from another state can turn a manageable case into a felony. Talk to a defense attorney before your arraignment or first hearing. The earlier you get a legal review of your case, the better chance we have to stop the state from using that old conviction against you. Let me review the prior case and fight to protect your future.
