A new Oklahoma law that lets prosecutors combine multiple pending DUI cases into a single felony charge is drawing sharp criticism from at least one criminal defense attorney, who says the statute's language is too vague and could unfairly influence juries before it even takes effect on November 1. Oklahoma state lawmakers passed the legislation to let prosecutors pursue more than one DUI offense committed within a single year as one combined felony case, and prosecutors and law enforcement partners have already begun preparing for the shift, meeting in Oklahoma City ahead of the law's implementation.
Criminal defense attorney Frank Urbanic told KOKH that the new law combines two pending misdemeanor DUI cases into one felony, but he believes a person must first be charged with one DUI before becoming eligible under the statute. He also said the law's violation threshold is unclear, and per Urbanic, the first violation is not required to be a conviction — leaving open basic questions about when the clock actually starts.
What Exactly Triggers the New Felony?
Urbanic questioned whether eligibility begins with an arrest, a charge, or a conviction, telling the station the ambiguity leaves defendants and their lawyers guessing. He noted that a felony DUI normally requires a disposition of the previous DUI case, and under the new statute, the first charge must be dismissed before the felony provision is activated. That procedural quirk, he said, could complicate how and when prosecutors decide to escalate a case.
The uncertainty matters because Senate Bill 1543, authored by Sen. Bill Coleman (R-Ponca City) and Rep. Emily Gise (R-Oklahoma City), was signed into law by Governor Kevin Stitt on May 21, according to the Oklahoma Senate. The law creates a legal mechanism allowing prosecutors to aggregate multiple DUI offenses committed within a 12-month period into a single Class C2 felony. Under the amended sentencing guidelines, a conviction carries a maximum penalty of up to seven years in prison, with offenders required to serve at least 20 percent of their sentence before becoming eligible for electronic monitoring or release, per the Official Oklahoma Session Laws.
Why Lawmakers Say the Loophole Needed Closing
The push behind the bill traces back to a procedural gap lawmakers say let repeat offenders slip through the cracks. Oklahoma Senate records show DUI cases in the state take an average of 51 weeks to reach final court adjudication, creating a nearly yearlong window during which repeat offenders could rack up multiple misdemeanor charges without triggering felony enhancements. That statistic featured prominently in legislative debate over the bill.
Public pressure to pass the law was also driven by the 2020 death of 19-year-old University of Central Oklahoma student Marissa Murrow, who was killed in a head-on turnpike crash by a repeat DUI driver who had accumulated four prior misdemeanor DUIs before ever facing a felony charge, according to OKW News. Murrow's parents went on to found the advocacy group Victims of Impaired Drivers, which also championed the Marissa Murrow Act, a separate law that took effect July 1 mandating specialized licensing and in-person training for venue bartenders across the state.
The Scale of Oklahoma's DUI Problem
Lawmakers cited sobering figures to justify the overhaul. The Oklahoma House of Representatives says the state experiences roughly 700 traffic fatalities annually, with state traffic safety officials attributing about half of those deaths to impaired driving. Final 2024 crash data from the National Highway Traffic Safety Administration, cited by the Addison Law Firm, shows 225 people died in alcohol-impaired crashes in Oklahoma out of 645 total traffic fatalities that year — a rise in alcohol-related deaths even as overall roadway fatalities declined.
Ahead of the new law's rollout, the Oklahoma District Attorneys Council convened prosecutors and law enforcement officers at the Impaired Driving and Prosecution Conference, where District Attorneys Association President Will Drake emphasized that DUI prosecutions are among the most technically demanding cases handled by state courts, according to the Grove Sun. SB 1543 builds on Senate Bill 54, an earlier overhaul that took effect November 1, 2025, expanding felony eligibility to first-time DUI offenders when aggravating factors were present, such as a blood alcohol content of 0.15 or higher, a minor passenger in the vehicle, or a resulting crash.
How Cross-County Cases Will Be Handled
The new statute also lays out jurisdictional rules for defendants facing charges in more than one county. An aggregated repeat DUI felony must be prosecuted in the county where the most recent violation occurred, and prosecutors in other counties where charges are pending may dismiss those misdemeanor cases without prejudice so they can be folded into the consolidated felony case, according to McBride & McBride Lawyers of Oklahoma.
Urbanic's sharpest objection centers on how combined cases might play out in front of a jury. He raised concerns about the law's potential impact on jury decisions, saying jurors may give more weight to a case with weak evidence when it's combined with a case that has strong evidence. He added that the change will cost his clients more time and money litigating the issues, and he said he does not believe the legislature adequately considered the law's implications before passing it.
The debate over SB 1543 echoes broader tension Hoodline has tracked in Oklahoma's courts this year, including one Oklahoma City mother's four-year wait for resolution in a DUI manslaughter case — the kind of judicial backlog lawmakers say the new felony-aggregation tool is meant to address. Whether the courts will resolve the open questions Urbanic has raised, including how eligibility is triggered and how jury prejudice challenges might unfold, remains to be seen before the law takes effect on November 1.
