When the Car Is Driving, Who’s Responsible for the DUI?

Florida has quietly become one of the more permissive states in the country when it comes to letting computers take the wheel. Fully driverless vehicles are already allowed on public roads here, no human operator required. That shift raises a question that sounds simple until you actually try to answer it: if a person is drunk inside a car that drove itself, has that person committed a DUI at all? The answer is not as settled as most people assume, and it is worth understanding before autonomous vehicles become as common on I-4 as they currently are rare.

Florida Already Redefined Who Counts as the “Driver”

Under Florida Statute 316.85, a licensed human operator is not required to operate a fully autonomous vehicle, and the vehicle’s automated driving system, not the person inside it, is treated as the operator for purposes of state traffic law. That single legal shift matters enormously for DUI cases, because Florida’s DUI statute is built around the idea of a human being in “actual physical control” of a vehicle. Remove the human from that equation, and prosecutors lose one of their most basic tools.

Actual Physical Control Was Never Designed for This

For decades, Florida courts have wrestled with what counts as being in control of a car, deciding cases involving people asleep behind the wheel with the engine running or parked on the shoulder with the keys in the ignition. Those cases assumed a person retained the ability to drive at any moment. An autonomous system disrupts that assumption entirely. A passenger who never touches the wheel, the pedals, or the controls is in a fundamentally different legal position than someone slumped over a steering wheel they could still use.

That does not mean intoxicated riders are automatically in the clear. Several open questions will shape how these cases get charged and defended in the coming years:

• Whether a person who can override the autonomous system at any time is still considered in control of the vehicle
• How officers and prosecutors will prove whether the automated driving system was actually engaged at the time of a stop
• Whether partially automated vehicles, which still expect human intervention, get treated differently than fully autonomous ones
• How insurance and liability rules under section 319.145 interact with criminal exposure
• Whether new legislation will explicitly address impaired occupants of self-driving vehicles, the way it already has for the vehicles themselves

The Technology Is Ahead of the Courtroom

Statutes tend to lag behind technology, and DUI law is no exception. Florida lawmakers moved relatively quickly to authorize driverless operation, but they have not yet fully addressed what happens when the person inside that vehicle is impaired. Until appellate courts or the legislature settle that gap, these cases will be decided one arrest at a time, often by officers applying old assumptions to genuinely new circumstances.

That uncertainty cuts both ways. It can create real defenses for someone charged with DUI while riding in an autonomous vehicle, but it can also mean officers charge first and let the courts sort out the legal theory later. Anyone facing that situation benefits from having Orlando DUI attorneys who understand both the statute and how it is actually being applied in Central Florida courtrooms. Our Florida DUI defense lawyers are prepared for exactly this kind of evolving legal terrain, where the facts of a case matter as much as the technology behind them.
