An officer in Montana may approach and check on a parked or stopped car without any suspicion of a crime, if specific facts suggest that someone inside needs help or is in danger. This is the community caretaker doctrine. It is a real exception to the usual rule, and it has a stopping point: once the officer knows you are fine, any further detention needs a separate legal basis. This page is part of our Montana DUI Guide.
How a Welfare Check Differs From a Traffic Stop
An ordinary stop requires particularized suspicion that someone in the vehicle has committed, is committing, or is about to commit an offense (MCA § 46-5-401(1)). Our page on the reasons police can stop you explains that standard.
A welfare check is not about an offense. The Montana Supreme Court adopted the community caretaker doctrine in State v. Lovegren, 2002 MT 153, 310 Mont. 358, recognizing that officers also investigate accidents and check on people for reasons unrelated to crime. When the doctrine applies, an officer may temporarily detain a person without a warrant and without particularized suspicion.
The Three-Part Lovegren Test
- Facts suggesting need. As long as there are objective, specific and articulable facts from which an experienced officer would suspect that a citizen is in need of help or is in peril, the officer has the right to stop and investigate.
- Appropriate help. If the citizen is in need of aid, the officer may take appropriate action to render assistance or mitigate the peril.
- The stopping point. Once the officer is assured that the citizen is not in peril, or no longer needs assistance, any actions beyond that are a seizure. They must be justified by something other than the doctrine, such as particularized suspicion or probable cause.
The Court tied the third part to the Fourth Amendment and to the greater protections of Article II, Sections 10 and 11 of the Montana Constitution.
How the Cases Have Come Out
| Case | What the officer saw | Result |
|---|---|---|
| State v. Lovegren, 2002 MT 153 | About 3 a.m., a car on the side of a highway, engine running, headlights off, driver apparently asleep and not responding to a knock. | Welfare check upheld. The driver might have been asleep, or ill and unconscious. Opening the door was justified. |
| State v. Spaulding, 2011 MT 204 | About 1:25 a.m. in January, a remote gravel road, temperature in the 20s. A vehicle pulled over abruptly and stopped while the deputy was still 200 yards behind. | Welfare check upheld. The deputy could reasonably suspect a breakdown or a lost driver. |
| State v. Graham, 2007 MT 358 | A pickup parked in a dirt pullout in plain sight of the road. Passing it, the deputy saw the two occupants kissing. She stopped to move them along. | Not a welfare check. Nothing suggested anyone was in peril. The denial of the motion to suppress was reversed. |
In Grahamthe Court was direct. It rejected the idea that the doctrine justifies a stop based on nothing more than a desire to "move someone along" or to prevent what an officer considers inappropriate public behavior. The trial court had reasoned that checking on a truck in the middle of nowhere could save a life someday. The Supreme Court held that was not enough when what the deputy actually saw removed any concern that the occupants were in trouble.
Is a Welfare Check a Seizure?
Often it is. In Spaulding, the deputy turned on his rear emergency lights, pulled in behind the stopped vehicle, and made contact. The Court held the driver was temporarily seized while he asked about her well-being. The question was whether that seizure was reasonable because it met the caretaker test, and the Court held it did.
The Court also noted that some welfare checks involve no seizure at all, such as an officer looking at an empty car on the shoulder whose driver has walked off for gas.
When a Welfare Check Becomes a DUI Investigation
The third part of the test is where most DUI cases are decided. The check ends when the officer is assured you are all right. But officers do not have to ignore what they notice while checking.
In Lovegren, the driver woke when the door opened and said, "I was drinking." The officer smelled alcohol and saw bloodshot eyes. The Court held those observations gave the officer particularized suspicion for field sobriety tests, which developed into probable cause for arrest. It called this a proper escalation under Hulse v. State, 1998 MT 108, the case that requires particularized suspicion of impairment before field sobriety tests.
So the questions in a case like this are specific:
- What facts, before the officer approached, suggested someone needed help?
- At what moment was the officer assured that no one did?
- What had the officer observed by that moment, and was it enough to keep going?
If the officer kept you after the welfare concern was resolved, with nothing yet pointing to an offense, what followed can be challenged with a motion to suppress (MCA § 46-13-302). How long any detention may continue is covered in how long a traffic stop can last.
Parked Does Not Mean Safe From a DUI Charge
People are sometimes surprised to be arrested when they were not driving. Montana's DUI statute applies to a person who drives or is in actual physical control of a vehicle (MCA § 61-8-1002(1)). The defendant in Lovegrenpleaded guilty to exactly that after being found asleep in the driver's seat with the motor running.
Whether a person in a parked car was in control is decided on the totality of the circumstances, and where the car was parked can matter too. Those issues are covered in actual physical control and private property and parking lots.
