Can you get a DUI for sleeping in your car in Arizona? Yes, and it happens more often than people realize. 

You probably already know it’s illegal to drive under the influence of alcohol or drugs (DUI), but you may not know that Arizona’s “actual physical control” (APC) law can lead to a DUI charge even when your vehicle never moves. Under APC, you can legally be in control of a motor vehicle while asleep inside it, and that is enough for police to make an arrest.

In this post, we discuss what actual physical control means under Arizona DUI law, and the factors that police, prosecutors, and juries in Arizona consider when deciding whether you were in actual physical control at the time of a DUI arrest.

Is It Illegal to Sleep in Your Car in Arizona?

Sleeping in your car is not illegal in Arizona by itself. But if you have been drinking, the answer changes. 

Under A.R.S. § 28-1381, you can be charged with DUI for sleeping in a car drunk if you are in “actual physical control” (APC) of the vehicle, even if the car never moves and you never turn the key.

What Does Actual Physical Control Mean for Arizona DUI?

Arizona’s DUI law, ARS 28-1381, makes it unlawful to drive or be in actual physical control of a motor vehicle. This raises the immediate question of what “actual physical control” means under Arizona law.

Unfortunately, Arizona statutes do not define this term. So, it has been up to Arizona courts to decide what it means through a series of decisions that, taken together, provide guidance on the factors to look for.

According to these court decisions, actual physical control over a vehicle means having the present ability to operate or control it, even if you are not driving it. 

The specifics of how to determine actual physical control have changed since 1954, the year of the first Arizona appeals court decision to consider the question involving a sleeping vehicle occupant.

At first, when determining actual physical control of the vehicle, courts paid particular attention to factors like whether the vehicle was parked off the road and whether the motor was running. This analysis was called the “safe harbor” or the “two-prong” test.

Since the Arizona Supreme Court’s decision in State v. Love in 1995, Arizona courts have applied a totality-of-the-circumstances test rather than the earlier, two-pronged safe-harbor approach. 

Today, when considering whether you are in actual physical control of a vehicle, even if you are sleeping, the jury must look at all the relevant facts on a case-by-case basis. Over time, examples of the factors that juries will consider when deciding the question of actual physical control have included:

• What is the location and position of the vehicle? Is it legally parked off the roadway, or stopped in traffic or on the side of the road? The easier it is to resume driving immediately, the more likely it is that actual physical control will exist.
• Is the engine running, or is the key in the ignition? A running engine is a strong indicator of actual physical control, and a key in the ignition is suggestive of it.
• If the key is not in the ignition, then where is it? The harder it would be for you to put the key in the ignition, the less likely a court is to conclude that you were exercising actual physical control. Are the keys on your person? Or someone else’s? Or is it put away in the glove box?
• Where are you in the vehicle? Are you sitting upright in the driver’s seat with your hands on or near the controls? Or are you sleeping in the back seat of the car? Again, your ability to quickly start driving the car is important; the easier it is, the more likely it is that actual physical control exists.
• Are the vehicle’s lights and other systems on? The more it appears that you have temporarily stopped driving but can resume, like the motor running, headlights on, heater or air conditioner running, the more likely that actual physical control exists.
• What time of day or night is it? Are you taking a nap in your car late at night or in the early hours of the morning? Or is it the middle of the day? The more likely it seems that you have stopped to “sleep it off” as opposed to simply taking a brief break from driving during the day, the less likely it is that a court will find you in actual physical control.
• Are you awake or asleep? If you are awake, it is easier to find that you are exercising actual physical control; nonetheless, if you are asleep but could easily resume driving when you awake, you can still be in actual physical control.
• What were your actions and statements when the police officer found you? Did you explain that you were trying to get some sleep? Or did you immediately reach for the controls and try to drive?

A unifying thread under all of these factors is whether you posed an imminent threat to public safety by resuming driving. 

So, it should be apparent by now that yes, you can get charged with DUI even if you are asleep in your car, as long as the totality of the circumstances suggests that you pose an imminent threat to the safety of the public.

How to Sleep in Your Car Without Getting a DUI in Arizona

The simplest advice to keep from being found in actual physical control is to not get behind the wheel of a car after you have been drinking alcohol. Find a place to sleep indoors, or have someone drive you home. You cannot have the capability to pose an imminent threat to the public by resuming driving when you are not in the vehicle.

If you must sleep in your car, then you can take the following steps to reduce the risk of being found in actual physical control.

• Park in a place where it is legal for you to do so, and as far away from traffic as you can get. A parking lot or a driveway, for example. Do not stop the car in a lane of traffic or just pull off on the shoulder.
• Shut the engine off, remove the key from the ignition, and put it somewhere out of reach. Put it in the glove box, the trunk, or give it to a sober friend.
• Get out of the driver’s seat. Sit or lie down in the back seat if your car has one, or in the passenger seat. The further away you are from the car’s controls, the better.
• Only run the engine if you absolutely must, for safety reasons, such as to avoid freezing to death. If a police officer finds you with the motor running, that will be evidence of actual physical control, no matter your intention, so keep the motor off if you possibly can.
• Once you have parked, stay parked. Any movement of the vehicle on a roadway while impaired qualifies as actual physical control under Arizona DUI law, even minimal repositioning. If your car is not in a safe position, it is better to call for assistance if you can rather than to drive it.

Do You Have Questions About Actual Physical Control in Arizona?

It may seem counterintuitive at first, but when you consider the public safety reasons that underlie it, the fact that you can be found guilty of DUI while sleeping in your car makes sense. 

The police and the courts will not spend time second-guessing your intention. The focus is on the potential threat you would pose to other drivers, pedestrians, and anyone else if you start driving again on a public road while you are intoxicated. 

If you follow the advice we have laid out above, you can significantly reduce the risk of being found in actual physical control, whether asleep or awake.
