The Arrest Report in Your DUI Case May Have Been Written by Software. California Now Makes Them Say So.
California's SB 524 took effect January 1, 2026, and it forces police reports to disclose when artificial intelligence drafted them, preserve the first AI draft, and log who ran the tool. In DUI cases, where the officer's narrative of odor, slurred speech, and field sobriety performance often is the case, that retained draft is new impeachment material. Utah requires disclosure and certification but no draft retention. Roughly 48 states require nothing at all.
A Jacksonville Panel Threw Out a Breath Test Over Five Rubber Rings. The Window to Use That Argument Is Closing.
A three judge Duval County panel suppressed an Intoxilyzer 8000 result this month because FDLE and the Jacksonville Sheriff's Office replaced O-rings inside the machine without being an authorized repair facility. The order is not the first ruling of its kind, and it is not the blank slate the coverage suggests. It follows binding appellate precedent from 2025, and it lands weeks after FDLE amended the very rule the argument depends on.
An Illinois Lab's Cannabis DUI Tests Couldn't Separate Delta-8 From Delta-9. Roughly 2,000 Cases Are Now in Question.
For eight years, Illinois courts treated delta-9 THC numbers from a University of Illinois Chicago lab as fact. On March 11, 2026, the state's forensic oversight commission rejected the university's own defense of those numbers as 'insufficient.' Here is how to find out whether your case is in the pool, and what remedy fits.
California's DUI Overhaul Has Two Weeks Left, and Most of It Is Already Dead
The Legislature must pass every bill by Aug. 31, and the Governor has until Sept. 30 to sign. But the headline bill in California's 2026 impaired-driving package, a first-offense ignition interlock mandate, is stalled on the suspense file and would not operate until 2031 even if it passes. Here is what actually survived, what died in the spring, and what a Jan. 1, 2027 effective date would really mean for a pending case.
Oklahoma Can Now Turn Two Unproven DUIs Into One Felony: SB 1543 Drops the Conviction Requirement on November 1
Starting November 1, 2026, Oklahoma prosecutors can aggregate two DUI violations committed within one year and charge them as a single Class C2 felony, with no prior conviction required. Here is what the statute says, what it leaves undefined, and why severance under 22 O.S. § 439 becomes the central defense tool.
Louisiana's New Twelve-Year DWI Minimum Took Effect August 1. It Reaches Far Fewer Drivers Than the Headlines Suggest.
Act 117 added a twelve-year mandatory minimum to Louisiana's DWI statute effective August 1, 2026. It fires only when the driver already has a vehicular homicide, third degree feticide, or first degree vehicular negligent injuring conviction. The baseline penalties for a second, third, or fourth DWI did not change. Here is what actually moved, and why a decades-old conviction can still trigger the new floor.
'They Catch Everybody': A New National Investigation Says Roadside Sobriety Tests Fail Sober Drivers, and Courts Are Listening
A multi-year, 22-state investigation and a 2023 randomized trial reach the same uncomfortable conclusion: roadside sobriety tests are good enough to justify an arrest but too unreliable to prove impairment in court. Here is what the tests measure, why sober people fail, and how defense lawyers are fighting the results.
Pennsylvania Just Invented a New DUI Crime That Turns Your Old ARD Into a Prior Offense
A 2025 win for Pennsylvania DUI defendants lasted less than seven months. After the state Supreme Court ruled in Commonwealth v. Shifflett that a prior ARD acceptance could not be used to enhance a DUI sentence, lawmakers responded with Act 58 of 2025, creating a brand-new offense at 75 Pa.C.S. 3802(h) that charges a fresh DUI as a second offense if you completed ARD within the past 10 years.
The .05 Blood-Alcohol Line Is Spreading: Washington Eyed a July Cutover, and Utah Is No Longer the Only Bill on the Table
Washington's Senate voted to drop the DUI threshold from .08 to .05 before the 2026 bill died in the House. Utah still stands alone in enforcement, but a growing list of states is pushing the same number. Here is what a .05 limit actually means for drivers and their defense.
Half of Sober Drivers Fail the Roadside Marijuana Test: Why Courts Are Starting to Throw Out Cannabis DUI Field Evidence
A UC San Diego clinical trial found trained officers rated nearly half of sober placebo participants as impaired on roadside sobriety tests. Defense attorneys are now using that number to challenge cannabis DUI arrests.
Two DUIs and You Lose Your Guns: Washington's Top Court Upholds Recidivist Disarmament Law 5-4 in McLellan v. Brown
In a 5-4 decision, the Washington Supreme Court upheld RCW 9.41.040, which bars firearm possession for people with two or more DUI-type convictions within seven years. The court held the state can categorically disarm repeat DUI offenders without any individualized finding of dangerousness. A four-justice dissent called it preemptive disarmament.
Your First DUI Now Means an In-Car Breathalyzer in 34 States: The 2026 Interlock Expansion (and Washington's New 15-Year Lookback)
For most of the country, a first DUI conviction now points toward an ignition interlock device rather than a flat license suspension. Here is what is actually mandatory, what California's 2026 law really changed, and why Washington's new 15-year lookback targets repeat offenders, not first-timers.
Karen Read Walked on Murder but Lost on DUI: Why the Conviction That Stuck Just Quietly Expired
A Massachusetts jury cleared Karen Read of murder, manslaughter, and leaving the scene. The only count that stuck was a misdemeanor OUI, and its one-year probation term quietly ran out on June 18, 2026. Here is why the charge nobody remembers is the one that mattered.
Refusing a Breathalyzer Is Now Its Own Crime in Florida, First Offense Included: Trenton's Law and the Suppression Fight Already Brewing
As of October 1, 2025, refusing a breath or urine test after a Florida DUI arrest is a crime on the very first offense, not just an administrative license matter. Here is what Trenton's Law changed and the three suppression arguments defense attorneys are already raising in 2026.
Your 2027 Car May Refuse to Start If It Decides You're Drunk. NHTSA Just Admitted No System Actually Works Yet
Federal law tells NHTSA to mandate built-in impairment detection in new cars. In a 2026 report to Congress, the agency conceded no production technology can reliably do it. For DUI defendants, the bigger question is what happens to the data when one of these sensors logs a reading.
Case v. Montana Hands Police a New Way Into Your Home Without a Warrant or Probable Cause
On January 14, 2026, a unanimous Supreme Court ruled that police can enter a home without a warrant under the emergency-aid exception based only on an objectively reasonable belief that someone inside is seriously hurt or in danger. Probable cause is not required. Here is what the decision says, why defense lawyers fear it for DUI and welfare-check cases, and how to challenge an entry dressed up as a rescue.
Smith v. Arizona Is Killing DUI Blood Tests: Why Surrogate Lab Analyst Testimony Is Getting Suppressed in 2026
The Supreme Court's 2024 ruling in Smith v. Arizona closed a Confrontation Clause loophole that prosecutors had used for over a decade to introduce blood-alcohol results without the analyst who ran the test. Two years on, the fallout is reshaping DUI suppression practice.
Lange v. California Is Finally Killing Warrantless Home Entry for DUI: Why Misdemeanor Hot-Pursuit Suppressions Are Surging in 2026
Five years after the Supreme Court rejected categorical hot-pursuit entry for misdemeanors, state high courts are finally applying the rule. Pennsylvania's 2025 Hunte decision shows where DUI suppression motions are winning, and how bodycam timestamps have become the decisive evidence.
Field Sobriety Tests Were Never Validated for Cannabis: Why DRE Officer Testimony Is Getting Tossed in 2026
The 12-step Drug Recognition Expert protocol was built for poly-drug roadside triage in the 1970s and 80s and never validated against a cannabis impairment threshold. NHTSA admits it in writing. State v. Moore, Williams v. State, and the April 2026 DOJ rescheduling order give the defense bar a deep Rule 702 playbook for attacking cannabis DUI cases in 2026.
Roadside Cannabis Testing Has No Legal Limit: Why DUI-D Cases Are Falling Apart After the Schedule III Move
After the DEA's April 2026 rescheduling of FDA-approved and state-licensed medical marijuana to Schedule III, defense lawyers are dismantling DUI-drug prosecutions built on per se nanogram thresholds, roadside oral-fluid screeners, and DRE testimony that cannot distinguish week-old metabolites from active impairment.
Over the Legal Limit but Not Automatically Guilty of Homicide: Why Prosecutors Have to Prove the DUI Caused the Death
A drunk driving conviction and a vehicular homicide conviction are not the same case. In Pennsylvania, New Jersey, and Michigan, prosecutors have to separately prove that the impaired driving actually caused the death, and that causation gap is where these cases are won and lost.
Legally Drunk but Acquitted: Why DUI Vehicular Homicide Cases Are Won on Causation, Not the Breath Test
In Pennsylvania, a driver can be over the legal limit and still avoid a homicide by vehicle while DUI conviction. Here is why these cases turn on causation, not the breath test, and what the 2026 Commonwealth v. Kling decision changed.
The Government's Fourth Amendment Double Standard: How New Suppression Motions Are Exploiting the Asymmetry in 2026
A May 2026 SCOTUSblog essay argues the government uses one Fourth Amendment for officers and another for defendants. Defense lawyers are now writing that asymmetry directly into suppression motions across DUI, drug, and digital-search cases.
Per Se THC Limits Are Failing as Junk Science: How Defenders Are Beating Marijuana DUI Cases in 2026
Six states still convict drivers on a blood THC number alone, but federal regulators, peer-reviewed pharmacology, and a 2025 wave of legislative reform now agree the science does not support it. Here is how defense lawyers are dismantling per se cannabis DUI cases.
