Yes, you can absolutely get a DUI (Driving Under the Influence) while in a self-driving car, depending on its level of automation and your location. The core issue is whether you are considered to be "in actual physical control" of the vehicle. With most commercially available vehicles today—which are Level 2 (partial automation) like Tesla's Autopilot or General Motors' Super Cruise—you are legally the driver. You are required to monitor the system and be ready to take over immediately. If you are intoxicated and sitting in the driver's seat, you are in physical control, making you susceptible to a DUI charge, even with the system active.
The Society of Automotive Engineers (SAE) defines six levels of driving automation, from Level 0 (no automation) to Level 5 (full automation). This distinction is critical for DUI law. For example, a 2023 study by the Insurance Institute for Highway Safety (IIHS) highlighted that drivers often over-trust Level 2 systems, leading to dangerous situations. If an officer pulls you over and determines you are impaired while a Level 2 or 3 system is engaged, you will likely face the same penalties as if you were driving manually.
The legal landscape is evolving but remains clear for present-day technology. Some states are beginning to discuss laws for fully autonomous vehicles (Level 4/5), where a human is not expected to intervene. However, these are not yet commercially available for personal ownership. Until then, the safest and only legally defensible choice is to never get behind the wheel after drinking, regardless of your car's capabilities. The responsibility remains squarely on the human in the driver's seat.
| SAE Level | Name | Driver Role | DUI Liability Risk (Current Law) |
|---|---|---|---|
| Level 0 | No Automation | Full-time driver | Very High |
| Level 1 | Driver Assistance | Driver must perform all tasks | Very High |
| Level 2 | Partial Automation | Must monitor and be ready to intervene | High |
| Level 3 | Conditional Automation | Must respond to takeover requests | High/Moderate (Gray Area) |
| Level 4 | High Automation | No driver required within specific conditions | Low (Theoretical, depends on law) |
| Level 5 | Full Automation | Passenger only | Very Low (Theoretical) |

Don't bet on it. My buddy thought his fancy car with "full self-driving" was a free pass. He got pulled over, blew over the limit, and got slapped with a DUI. The cop said since he was in the driver's seat and could take over, he was in control of the car. The judge agreed. It's a really expensive lesson. That technology isn't a robot chauffeur yet; you're still the driver in the eyes of the law.

From a standpoint, the key phrase is "actual physical control." Even if the car is driving itself, an intoxicated person in the driver's seat is deemed to be in control of a several-thousand-pound vehicle. Most states' DUI statutes do not make an exception for advanced driver-assistance systems. The law is playing catch-up with technology, but until specific legislation is passed for fully autonomous vehicles, the conservative and correct interpretation is that a DUI applies.

I look at it like this: the car's system is an assistant, not a replacement. If you're drunk and your assistant makes a mistake, you're still the boss who's responsible. The car's manual even says you need to stay alert and keep your hands on the wheel. If you're passed out or slurring your words, you're clearly not doing that. So yeah, you're breaking the law twice over—being drunk and misusing the safety feature.

Think of it as a spectrum of risk. With today's cars, the risk is extremely high. The law is unambiguous for any vehicle where a human must supervise. The gray area might appear with future, truly driverless cars where there isn't even a steering wheel. But for now, that's science fiction for most of us. The practical advice is simple: if you've been drinking, your car—no matter how —is not your ride home. Call a taxi, use a rideshare, or designate a sober driver. It's the only guaranteed way to avoid a life-altering charge.
