Did You Know That Oklahoma’s Impaired Driving Laws Now Include THC?
As of November 1, 2025, Oklahoma introduced significant updates to its impaired driving laws which now include regulations around marijuana. These changes can impact workplace safety policies and compliance strategies.
At TEAM, we believe informed organizations make safer decisions. Here’s what’s new and why it matters for your business.
Senate Bill 54: Stricter Standards for Drug-Impaired Driving
Under SB 54, enforcement has become more stringent. Any detectable THC or metabolites can result in a DUI charge, regardless of impairment level.
An important thing to note is that medical marijuana cardholders are not exempt. Additionally, the previous two-hour testing window has been eliminated, allowing prosecutors to use test results from any time after arrest.
Did you know? Experts estimate that 1 in 10 Oklahomans could be at risk of a DUI charge on any given day simply because THC can remain in the body long after use, even when the individual is not impaired.
Aggravated DUI: Felony Risk for First-Time Offenders
Certain conditions now elevate a DUI to Aggravated DUI, a felony offense:
- Accidents involving injury or property damage
- Reckless driving or speeding 20+ mph over the limit
- Transporting a passenger under 18
- Attempting to elude law enforcement
If THC is detected under these circumstances, mandatory jail time applies—even for first offenses.
Expanded Rules on Open Containers & Consumption
The law also prohibits:
- Smoking or consuming marijuana in a moving vehicle
- Passengers using marijuana while the car is in motion
- Open marijuana containers in the passenger area
Violations can lead to fines up to $500, plus additional penalties.
This new update is to “protect motorists and families by including additional offenses such as causing a motor vehicle incident, eluding police, speeding in a school zone, having a minor in the vehicle, or committing other reckless acts while driving under the influence under the definition of Aggravated DUI, a felony offense.”
— Oklahoma Senator, Darrell Weaver
Why Employers Should Act Now
Legal marijuana use does not mean it’s legal to drive under its influence. THC can remain in the body long after use, and under SB 54, even trace amounts can have serious consequences.
Employers should review and update their drug and alcohol policies, reinforce expectations with employees, and consider Reasonable Suspicion Training for supervisors.
The Bottom Line
Oklahoma’s new marijuana DUI law isn’t just about penalties, it’s about safety. Stay informed, update your policies, and ensure your team understands the risks.
