As I understand it, if one is found inside one's car with the keys while drunk, even if asleep, one is as guilty of drunk driving as if one was actually driving. If one finds oneself over the limit, without a place to sleep but with access to one's car is there a way to legally use the car for shelter for the night?

Some ideas that come to mind, that may or may not make a legal difference:

  • Leave the car keys with the bartender, sleep in the car without access to the keys, collect the keys in the morning.
  • Put the keys under a rock some distance from the car
  • If two people found themselves in this situation, they could each sleep in the others car, keeping their own keys with them
  • Use the car to support a tarp, and sleep outside the car under the tarp

As far as jurisdiction, I am particularly interesting in England and Wales, but it seems the sort of thing that must come up all over the world so answers for any jurisdiction would be interesting.

In New Hampshire (USA) our law was as you stated until 2020. That is, if a person over the legal limit was sleeping it off in a car and either had the car keys in their possession or had unrestricted access to the car keys, they were deemed to be in "actual physical control" of the vehicle and could be convicted of operating a motor vehicle under the influence.

The nonsensical nature of this law eventually led to public lobbying for a change. In 2020 the law was changed so that as long as the drunk person is not in the driver's seat, no law is broken. They could even leave the car running so they don't freeze to death while they sleep it off.

The law, NH RSA 265-A:1(VI) now contains this provision in its Definitions:

"Drive," or "attempt to drive," or "actual physical control" shall not include sleeping, resting, or sheltering in place in a vehicle parked in any place where parking is permitted, provided that the person is not seated at the controls of the vehicle.

TL;DR: You can sleep drunk in your car but you shouldn't give the impression that you're attempting to drive.

The German criminal code says, in section 316:

Whoever drives a vehicle in traffic (sections 315 to 315e) although they are not in a condition to drive the vehicle safely due to having consumed alcoholic drinks or other intoxicating substances incurs a penalty of imprisonment for a term not exceeding one year or a fine, unless the offence is subject to a penalty under section 315a or 315c.

Of course, the question is what exactly "drives" means (and whether "drives" is an adequate translation; to me, it seems like "drive" actually means moving the car, while the original German word "führt" could be interpreted as "controls")

A German administrative court ("Verwaltungsgericht") said in this decision:

Ein Fahrzeug führt derjenige, der es unter bestimmungsgemäßer Anwendung seiner Antriebskräfte unter eigener Allein- oder Mitverantwortung in Bewegung setzt oder das Fahrzeug unter Handhabung seiner technischen Vorrichtungen während der Fahrbewegung durch den öffentlichen Verkehrsraum ganz oder wenigstens zum Teil lenkt, wobei der etwa vorhandenen Motorkraft als Ursache der Bewegung keine Bedeutung zukommt.

translation by deepl.com:

A vehicle is driven by anyone who sets it in motion under their own sole or joint responsibility using its driving power as intended, or who steers the vehicle in whole or at least in part using its technical equipment while driving through public traffic areas, whereby any engine power present is of no significance as the cause of the movement.

This should mean that a car that doesn't move is not driven.

In this case (in German), a man sat in the driver's seat, started the motor and turned on the light, then stopped the motor again as his wife said it might be better to walk. Some officers in a passing police car saw that, and the man ended up being convicted; this conviction was overturned by the highest German court. So, as long as the car isn't moving, you're not driving, and §316 doesn't apply.

Still, running the motor can get you in some trouble with the police, and winning your case in court after several weeks or months of having your license suspended probably isn't what you'd call a favorable outcome. And indeed, several non-juristical websites give general advice that you can sleep in your car, drunk, if you make sure that it's unreasonable to assume you're making an attempt to drive. For example here, section 44, the magazine says (again translated by deepl and slightly edited to reflect the original formatting):

Item 44: "I'm not allowed to spend the night drunk in the car." Actually, this is permitted in principle. However, it must not appear that the vehicle was being driven under the influence of alcohol or is to be put into operation. If this is the case, the person sleeping drunk could be charged with attempted driving and thus an attempt to commit a criminal offense. However, if you follow the following two instructions, you are on the safe side.

Firstly: Never sleep in the driver's seat. The best (and usually most comfortable) place to sleep is on the back seat, but the front passenger seat is also fine, as the car cannot be started from there without further ado. And secondly: do not insert the ignition key. Not even to switch on the heating or air conditioning. The vehicle will then be more ready for operation than it should be. Cars with keyless go systems are permanently ready to drive, but the ignition should remain switched off to avoid misunderstandings.

    And some countries (Netherlands), don't allow sleeping in your car at all without permission from the land owner (and on public land it is not allowed), but this is unrelated to being drunk or not.

Don’t be in the driver’s seat

If you are in the back seat or passenger seat or boot (trunk), you aren’t in control of the vehicle.

s112 of the Road Transport Act 2013 says:

(1) A person must not, while under the influence of alcohol or any other drug—

(a) drive a vehicle, or

(b) occupy the driving seat of a vehicle and attempt to put the vehicle in motion, or

(c) if the person is the holder of an applicable driver licence (other than an applicable provisional licence or applicable learner licence)—occupy the seat in or on a motor vehicle next to a learner driver who is driving the vehicle.

Yes, it is legal to sleep in your car when drunk, but...

This is the law (Road Traffic Act 1988, section 4) that covers the offence:

(1)A person who, when driving or attempting to drive a [F1mechanically propelled vehicle] on a road or other public place, is unfit to drive through drink or drugs is guilty of an offence.

(2)Without prejudice to subsection (1) above, a person who, when in charge of a [F1mechanically propelled vehicle] which is on a road or other public place, is unfit to drive through drink or drugs is guilty of an offence.

(3)For the purposes of subsection (2) above, a person shall be deemed not to have been in charge of a [F1mechanically propelled vehicle] if he proves that at the material time the circumstances were such that there was no likelihood of his driving it so long as he remained unfit to drive through drink or drugs.

Section (3) allows for circumstances such as sleeping in your car, or retrieving items from your car when drunk, however note that the act says that the person must prove that "the circumstances were such that there was no likelihood of his driving" which is a difficult criterion for someone who has chosen to sleep in their car to demonstrate.

According to section 236 of the Criminal Code, you have to "drive" the vehicle in order to commit the crime. Driving is understood as starting (ie. putting it in motion) or controlling the already moving vehicle. Also, intent matters. You have to be aware of that you are going to drive while under the influence.

Note that the official translation uses "operates" instead of "drives": It's an incorrect translation of the Hungarian verb vezet (drives); you may "operate" the vehicle, eg. turn on the radio or seat heating, provided you don't drive it.


Different jurisdictions have different criteria for both "driving" and "drunk", sometimes beyond a sane person's understanding.

What you can (almost?) everywhere do safely:

  • get a sober and driving-licensed person at the driver's seat. The person may be awake or sleeping.
  • set the key, the card, the fob or whatever (if any) controlling device the car uses in this person's control.
  • sleep as much drunk as you want using the other available seats, the trunk, the roof, whatever.
  • At least in The Netherlands, you can't sleep in a car in public place, or generally without permission from the landowner. The location in the car doesn't matter, nor whether you are drunk or sober.

It's not against the law, but (almost?) all local municipalities have rules against wild camping, which includes sleeping overnight in a car.

He considered formally contesting the fine arguing he was napping and not sleeping overnight, but decided it wasn't worth it.

In , , , sleeping overnight in a parked car is interpreted as wild camping and therefore prohibited in most places (some motorway rest stops in The Netherlands are reportedly allowed up to 24 hours, and some places prohibit sleeping in parked cars entirely). Napping might be allowed. Whether you are napping or sleeping overnight is in practice up to the interpretation of the officer. A friend in The Netherlands was fined when he was napping at 02:00 (sober) and refrained from contesting his fine on the claim that he was napping and not sleeping overnight.

Dutch language source.

The rule does not depend on being drunk or sober nor on what seat in the car you occupy.

However, the consequences of sleeping in a car are surely much less severe (low-moderate fine) than the consequences of drunk driving (very high fine, loss of license, or worse).

So if you are sleeping in your car, how do you show that you intend to not drive?

This policeman said, "Put your keys on the dashboard, on the passenger side."

    I am a UK resident. I think the logic is... If you have driven while drunk, then you are guilty of drink-driving. Even if someone spiked your drink, your are guilty. If you realise you may be drunk, and stop, and arrange things so you can drive no further, then you have shown the wish to do the right thing. You are still guilty of drink-driving but the arresting officer may recognise this and not test you. This has to be convincing: you can't just have a little sleep if you feel woozy, then pick up the keys again. Commented Nov 19, 2023 at 13:03

Logically it must be possible in theory to enter (and presumably sleep in) a vehicle whilst drunk, otherwise you couldn't (for example) enter a motor home or a coach whilst drunk.

Obviously the courts are alert to devious would-be drink-drivers who are stopped in pub car parks with the engine running, but claim they were intending to heat the car up by running the engine and then go to sleep in the driver's seat.

I think the general principle is that to either enter the driver's seat and/or to insert the ignition key when drunk, would cause grave risk of arrest and conviction - regardless of what you say your intentions actually were.

Going to the boot to fetch bedding and then entering the back seat to sleep is perfectly lawful in principle. I have myself gone to sleep across the dropped back seats and boot of my hatchback car in the past like this, though I was careful to avoid any scene that might seem ambiguous.

    What if one affixed a cable lock to the ignition of an automatic car in such a fashion that it could not be removed from "PARK". In northern climates, sleeping inside a running car may not be without risk, but the risk of asphyxia from a properly maintained vehicle may be less than the risk of hypothermia if the heater isn't used.

    @supercat, obviously cases turn on the evidence and the circumstances, but operating any of the controls in a manner which a driver might, or even just entering the driving seat at all, may create an impression about your intentions which is difficult to rebut. Mentioning hypothermia can easily suggest your real intention or propensity was to drive the car home. The judges are not credulous with this offence at all, and an intention to drive is not exactly the question, it is whether you were "in charge" - a nebulous and more expansive concept.

    @supercat, the car doesn't have to move, or be immediately movable, for you to be considered "in charge" as the driver. You don't even have to be in it - just being in the vicinity can be enough to be treated as "in charge". As I say in another comment, it's better to treat being in your own car with the keys whilst drunk, as being prima facie illegitimate and proof of the criminal offence, and from there on you're asking for the court to grant your excuse out of general indulgence. It's the same as carrying a jemmy on the street at night - there may be a good excuse, but you have to prove.

Drunk driving laws require two facts, that the BAC of the operator exceeds a legal limit, and that the operator was causing the vehicle to move. While you can do extreme things like sleeping on the passenger side or in the back, that's completely unnecessary. If where you are parked and sleeping is legal for parking and sleeping, then you're doing nothing illegal while parking and sleeping. The alcohol doesn't change anything, because all three of these elements are perfectly compatible as far as the law is concerned.

While Dave's answer is perfectly fine, I'd say it's not as pragmatic as what I'd suggest. First, keep a pillow and blanket in the car. When you park, make sure it's a legal parking area and sleeping/overnight stays are allowed, turn off the engine and lights, disengage the seatbelt, engage the parking brakes, slide and recline the seat back as far as it goes, make sure the ignition key is in the OFF position, and use the pillow and blanket for comfort and warmth. The most important thing, however, is to not move the car an inch if the cops know you're likely impaired.

If an arrest is made without clear evidence that an individual was operating the vehicle leading up to the arrest while also impaired, that is a case that's likely going to be thrown out of court or will end up with a not guilty verdict. There may even be an opportunity for a wrongful arrest lawsuit, depending on the jurisdiction.

    Being drunk in the driver's seat in the UK is risky. I think you don't actually have to move the car, but have the ability to move it. I might be wrong, but police will think exactly the same. I would not take the risk, but get into the back. If you need to enter the car from the front to get into the back, I'd try to do that on the passenger site. And having to go to court is highly inconvenient even if you are found not guilty. If that happens then you should have a lawyer and that won't be free.

    "no likelihood of his driving it" requires proving inability to move the car - e.g. you still can drive a car by pressing the coupling and rolling down a hill, and a key in the ignition can be turned in a moment, meaning the car is driven. In fact, a person sitting in the driver seat with key in the ignition is a clear indicator that the person drove till the moment they shut down the car for the nap.
