DUIs in Electric Vehicles: What’s Different in Illinois?

With electric vehicles, especially those with advanced driver-assist features like Tesla’s Autopilot, many drivers assume that they’re in a safer position when it comes to DUI laws. Unfortunately, that’s not the case. Illinois law still requires a driver to be in control of the vehicle at all times, even when the car is operating in autopilot mode. Local law enforcement agencies, especially in the Chicago area and the suburbs, are adapting to the rise of EVs by training officers on how to spot DUIs involving these cars. While Tesla might be the most well-known EV brand, Illinois police are prepared to handle any make or model. Whether it’s a Tesla, Rivian, or Ford Mustang Mach-E, the same DUI laws apply. It’s important to remember that just because your car has autopilot doesn’t mean you can legally drink and let the car “drive itself.” Cases involving autopilot and DUIs are already popping up in Illinois, especially around the suburbs where Tesla vehicles are common. Local law enforcement is paying attention, particularly on major highways like I-88 and I-55, where EV traffic is on the rise.

Autopilot Isn’t a Defense (Here’s Why)

One of the most common misconceptions about electric vehicles is that if the car is in autopilot mode, you’re not really “driving,” so DUI laws shouldn’t apply. However, Illinois law is clear: you’re still responsible for the vehicle, even if it’s using advanced driving features. Autopilot can assist, but you’re required to maintain control and be ready to take over at any moment. Several court decisions in Illinois have confirmed that drivers using autopilot can still be charged with a DUI. Judges in Cook County have made it clear that autopilot is not a defense. There’s even been an increase in local cases where drivers tried to argue that their car was doing the driving, but those arguments have consistently failed. Prosecutors focus on the fact that even with high-tech features, the driver must remain in control, and if impaired, the risk is the same.

How Cops Spot EV DUIs

Patrolling for DUIs in EVs requires some adjustments, but Illinois police have already started adapting. Officers are trained to notice different driving behaviors with electric vehicles, such as erratic speed changes or unusual braking, which may be influenced by features like regenerative braking or autopilot. In DuPage County, along the busy Tesla corridor on I-88, officers are specifically trained to detect signs of impairment in drivers of electric vehicles, while Will County’s highway patrol has focused on EVs around major charging stations.With EVs being quieter, police may rely on other cues like weaving or sudden stops at intersections to spot impaired drivers. Local police are also becoming familiar with technology that allows them to check whether a car was in autopilot mode at the time of the stop. Even if you aren’t actively steering, being behind the wheel while impaired is enough for an arrest.

EV Data: How Evidence Collection Is Changing

One of the unique aspects of electric vehicles is the amount of data they collect. EVs often log information like speed, braking, and whether autopilot or other driver-assist features were engaged. In Illinois DUI cases involving EVs, this data can be critical. Local courts, particularly in Cook and DuPage Counties, have already started seeing cases where vehicle logs are used as evidence.For example, prosecutors might use data to show that the driver was switching in and out of autopilot or driving erratically before being pulled over. Courts are also accepting app data, such as Tesla’s mobile app, which records vehicle status in real time. Judges consider this evidence alongside traditional methods, like field sobriety tests, to determine the driver’s level of control at the time of arrest.

Special Issues with Charging Stations

Charging stations present a unique challenge when it comes to DUIs. Many drivers assume that because they’re not technically “driving” while charging, they’re safe to have a drink. However, Illinois law doesn’t see it that way. If you’re sitting in your car, even while it’s charging, and have the key fob in the vehicle, you could still be charged with a DUI. Public charging stations, especially in Chicago and suburban malls, are becoming hotspots for police patrols. Officers are aware that some drivers may see charging time as an opportunity to relax and have a drink, but if they catch you impaired behind the wheel—even while plugged in—you could be facing serious consequences. Local shopping centers with charging stations, like Oakbrook Center in DuPage County, are common locations for these types of incidents.

What This Means for Your Defense

If you’re facing a DUI charge in an electric vehicle, your defense strategy may need to be slightly different. Technology plays a huge role in these cases, and your lawyer will likely need access to the data your vehicle recorded leading up to the stop. Additionally, Illinois courts are increasingly relying on expert witnesses who understand EV technology to explain how features like autopilot work in relation to DUI laws. Counties like Will and DuPage are seeing more cases involving electric vehicles, and local lawyers are adjusting their defense strategies accordingly. There may be opportunities to use the vehicle’s data to challenge the prosecution’s case, but this requires specific knowledge of how EVs record information. It’s also important to be aware that EV DUIs are being closely monitored by law enforcement, and knowing the local court tendencies can make a big difference in your case.

Real Tips for EV Owners in Illinois

If you own an electric vehicle in Illinois, it’s important to understand how DUI laws apply to you. Here are a few real-world tips to keep in mind:

• Be cautious at charging stations. Even if you’re not driving, sitting behind the wheel while impaired can still lead to a DUI charge.

• Use a ride service if you plan to drink, especially if you’re traveling to a popular EV charging spot.

• Know your vehicle’s data—if you’re ever involved in a DUI case, this information could be used as evidence for or against you.

• Stay aware of local enforcement patterns—certain areas, like Tesla hotspots in the Chicago suburbs, are more heavily patrolled for DUI violations.

Navigating EV DUIs in Illinois

While electric vehicles are changing the way we drive, Illinois DUI laws haven’t changed to accommodate that technology. Whether you’re driving on autopilot or sitting at a charging station, you’re still responsible for being sober behind the wheel. Understanding how local law enforcement is adapting to this new technology and being aware of your legal rights can help you avoid a DUI charge in your electric vehicle.
