Choosing Your Defense Attorney You open your phone, call a ride, and step into a self-driving Tesla Cybercab. The car has no steering wheel, no gas pedal, and no brake pedal. As you sit in the back seat, police pull the car over. Can police arrest you for DUI?
As self-driving technology grows, driverless taxis raise new legal questions across Pennsylvania. State DUI laws were written years ago for human drivers sitting behind steering wheels. Understanding how state laws apply to self-driving cars is important for anyone using these modern transit options.

To understand whether a passenger in a driverless car can face charges, you must look at Pennsylvania’s main DUI law (75 Pa.C.S. § 3802).
Under state law, prosecutors do not always have to prove that you were steering a moving car down the road. Instead, the law states that a person cannot drive, operate, or be in “actual physical control” of a car while impaired by alcohol or drugs.
The law covers three distinct actions:
In standard DUI cases, courts use actual physical control to cover situations where police find a car pulled over or parked. For example, people have faced DUI charges after sleeping in a running car in a parking lot. Courts check several simple facts to decide control:
A passenger in a fully self-driving taxi sits in a very different legal position than a traditional driver.
Vehicles like the Tesla Cybercab are built without standard driving equipment. There is no steering wheel to turn and no floor pedals to press. A passenger cannot physically control the steering or braking because those parts do not exist inside the cabin.
When you use a phone app to call a driverless ride, you enter a pickup spot and a stop. Legal experts note that picking a stop on an app is no different from telling a human taxi driver where to go.
Selecting a route does not make you the driver of the car. Onboard computers, sensors, and automated software control steering, speed, stopping, and lane changes.
It is vital to know the difference between being arrested by police and being convicted in a Pennsylvania court.
When police stop a vehicle, they look for signs of alcohol or drug use. If an officer sees a car stop unexpectedly, they may approach the car and smell alcohol.
Because driverless cars are still new, an officer might assume the passenger was driving or controlling the car. Police can make an arrest if they believe they have probable cause at the scene.
While police can make an arrest based on initial suspicion, winning a conviction in court requires much more. Prosecutors must prove guilt “beyond a reasonable doubt.”
In a driverless taxi case, prosecutors must present clear proof showing that the passenger exercised actual physical control over the vehicle’s movement. If the vehicle drove entirely on its own software, proving physical control becomes very hard for the state.
If someone faces DUI charges while riding in a self-driving taxi, an experienced Pennsylvania criminal defense lawyer will review key evidence:
Police can make an arrest if they suspect a crime. However, to get a DUI conviction under 75 Pa.C.S. § 3802, prosecutors must prove you were driving, operating, or in actual physical control of the car’s movement.
Actual physical control means having the immediate physical power to operate the car. In standard cases, courts check if a person had access to the keys, engine, and steering wheel.
Entering an address on a ride app or screen is viewed as telling the vehicle where to go, just like telling a taxi driver your stop. It does not give you physical control over steering or brakes.
Key evidence includes car computer logs, ride app receipts, GPS trip records, interior camera video, and police bodycam recordings.
Stay calm and polite. Show your identification if asked, but exercise your constitutional right to remain silent until you speak with a criminal defense attorney.
