Key points
- Operating a motor vehicle is the first element of OWI, and the prosecution must prove it, like every element, beyond a reasonable doubt.[1][2]
- "Operate" means to drive or to have actual physical control of the vehicle, and a person keeps operating until the vehicle no longer poses a significant risk of collision.[3][4]
- Operation can be proved by circumstantial evidence alone, and police may arrest after a crash without having seen the driving.[5][6]
- The corpus delicti rule limits use of a confession without independent evidence of the crime, but it does not require independent proof of who did it, and it applies only to confessions, not to admissions of single facts.[7][8][9]
In a Michigan OWI case, the prosecution must prove that the defendant "operated a motor vehicle," and it must prove that element, like every other, beyond a reasonable doubt.[1][2] When the dispute is about who was driving, or whether anyone was driving at the relevant time, the question is how that element is proved: through the statutory definition of "operate," direct and circumstantial evidence, and statements, subject to rules such as the corpus delicti rule.[3][5][7]
This page explains those rules. The broader question of what conduct counts as "operating" (sleeping in a parked car, automated vehicles, scooters) has its own page, what counts as operating a vehicle.
Operation is an element the prosecution must prove
The Court of Appeals describes OWI as having three elements: (1) the defendant operated a motor vehicle, (2) on a highway or other place open to the general public or generally accessible to motor vehicles, (3) while under the influence or with an unlawful bodily alcohol content.[1] Jurors are told the defendant is presumed innocent and is "not required to prove [his or her] innocence or to do anything," and that if the prosecutor has not proven every element beyond a reasonable doubt they must find the defendant not guilty.[2]
So a "who was driving" dispute is not an affirmative defense the defendant must prove. It is a challenge to whether the prosecution's evidence on the first element is enough.[2]
What "operate" means
MCL 257.35a defines operating as being in actual physical control of a vehicle, or causing an automated motor vehicle to move under its own power in automatic mode on a highway or street, whether or not the person is inside it.[10] The jury instruction tells jurors: "To operate means to drive or have actual physical control of the vehicle."[3]
Operation does not stop the moment the wheels stop. In People v Wood, the Michigan Supreme Court said that once a person puts a vehicle in motion, or in a position posing a significant risk of causing a collision, "such a person continues to operate it until the vehicle is returned to a position posing no such risk."[4] In People v Lechleitner, the Court of Appeals affirmed an OWI-causing-death conviction where the intoxicated driver crashed and his car sat in the middle of a freeway at night; the vehicle need not have been moving at the time of the fatal collision.[11]
The place element is separate. A private driveway and parking lots can qualify, which is discussed in where the law applies.[12][13]
How operation is proved without an eyewitness
Jurors are instructed that facts can be proved by direct evidence (what a witness saw or heard) or by circumstantial evidence, which "normally or reasonably leads to other facts," and that "circumstantial evidence by itself, or a combination of circumstantial evidence and direct evidence, can be used to prove the elements of a crime."[5] In disputes over who was driving, the evidence offered can include some of the following. This list describes the kinds of evidence parties present; it is not a statement of what any court requires.
- Witness accounts from other drivers, passengers or bystanders.
- Police dash-camera or body-camera video, and the officer's observations on arrival.
- Physical facts: the position of the people and the car, keys, seat and mirror settings, and injuries consistent with a seat position.
- Statements by the defendant or others at the scene.
- Records such as 911 calls, phone data or vehicle data.
Whatever the mix, the jury decides what the evidence proves and whether it reaches the reasonable-doubt standard.[2][5] Body-camera recordings must be kept at least 30 days, and until the end of any pending criminal investigation or prosecution.[14] For how to request them, see discovery and video evidence.
Arrest when the officer did not see the driving
Two statutory rules let an officer arrest for OWI without a warrant even though the officer never saw the car move:
- After a crash. An officer may arrest a person the officer has reasonable cause to believe was the operator of a vehicle involved in a Michigan accident and was operating in violation of section 625.[6]
- Driver's seat, car in the roadway. An officer may arrest a person found in the driver's seat of a vehicle parked or stopped on a highway or street if any part of the vehicle intrudes into the roadway and the officer has reasonable cause to believe the person was operating while intoxicated.[15]
These rules concern the lawfulness of the arrest, which uses the "reasonable cause" standard.[6][15] They do not lower what the prosecution must prove at trial, which is each element beyond a reasonable doubt.[2] Crash investigations are covered in OWI investigations after a crash.
Statements and the corpus delicti rule
The corpus delicti rule is a rule Michigan courts apply to confessions, designed to prevent the use of a confession to convict a person of a crime that did not occur. It provides that a defendant's confession may not be admitted unless direct or circumstantial evidence independent of the confession establishes the occurrence of the specific injury and some criminal agency as its source.[7] Three limits on the rule matter in "who was driving" cases:
- Identity is not part of it. "Proof of the identity of the perpetrator of the act or crime is not a part of the corpus delicti"; it is enough to show the crime was committed by someone.[8]
- Confessions only. "The corpus delicti rule is confined to confessions," not admissions of individual facts.[7]
- One element is not a confession. In People v Washington (2024), the Supreme Court held that "an admission of one, but not of all, the essential elements of the crime is not a confession."[9]
Washington involved body armor, not driving, and this guide did not verify how Michigan courts apply these limits to a driver's statement such as "I was driving."[9] The general rule's application to the operating element in OWI cases is an open point in the sources reviewed.
Separately, whether a statement is admissible at all can raise Miranda questions. Miranda applies to custodial interrogation even for traffic misdemeanors, but ordinary roadside questioning during a routine stop is ordinarily not custody.[16][17] See Miranda warnings and OWI stops and motions to suppress evidence.
Common misunderstandings
| Belief | What the law says |
|---|---|
| No one saw me drive, so there is no case. | Circumstantial evidence alone can prove an element, and officers may arrest after a crash without seeing the driving.[5][6] |
| Once the car stopped, I was not operating. | Operation continues until the vehicle no longer poses a significant risk of collision (Wood).[4] |
| A confession can never be used without other proof I was the driver. | The corpus delicti rule does not require independent proof of identity.[8] |
| The defendant has to prove someone else was driving. | The prosecution must prove each element beyond a reasonable doubt; the defendant is not required to prove anything.[2] |

Common questions
Can I be convicted of OWI if no one saw me driving?
It is possible. Jurors are told that circumstantial evidence by itself, or combined with direct evidence, can be used to prove the elements of a crime.[5] The statute also lets an officer arrest without a warrant a person the officer has reasonable cause to believe was the driver in a crash, even though the officer did not see the driving.[6] The prosecution still has to prove operation beyond a reasonable doubt.[2]
If I told the officer I was driving, is that enough by itself?
Michigan's corpus delicti rule bars a confession unless independent evidence shows the specific injury and criminal agency, but proof of who committed the act is not part of that requirement.[7][8] The Supreme Court has also held that an admission of one, but not all, elements of a crime is not a confession for this rule.[9] How courts apply this to a driver's statement in an OWI case was not verified for this guide.
What if I was in the passenger seat when police arrived?
The question is still whether the prosecution can prove that you drove or had actual physical control of the vehicle at a relevant time.[3] Evidence such as witness accounts, video, injuries, keys, seat position and statements may be offered, and the jury weighs it.[5] No single fact decides the element under the sources in this guide; it depends on the whole record.
Does pulling over and stopping end "operating"?
Not necessarily. The Michigan Supreme Court in Wood held that once a person puts a vehicle in motion, or in a position posing a significant risk of collision, the person continues to operate it until it is returned to a position posing no such risk.[4] In Lechleitner, a crashed car left in the middle of a freeway at night was still being operated.[11]
Do statements I made at the roadside come in?
Miranda warnings are required for custodial interrogation, even for traffic misdemeanors, but a motorist detained in a routine traffic stop is ordinarily not in custody.[16][17] Whether a particular statement is admissible is decided by the judge, for example on a motion to suppress. On request, the prosecutor must provide the defendant's written or recorded statements.[18]
