In Missouri, driving, possessing, or buying a vehicle without the owner’s consent is usually charged as tampering in the first degree, a class D felony. It often comes from situations that look very different from car theft: a borrowed car, a disputed sale, or a ride with the wrong person.
This guide covers tampering with a motor vehicle under RSMo 569.080, how it differs from stealing a vehicle and from second degree tampering, and how these cases are defended.
The charge
What is tampering with a motor vehicle in Missouri?
Knowingly receiving, possessing, selling, or unlawfully operating a vehicle without the owner’s consent.
Under RSMo 569.080.1(2), a person commits tampering in the first degree if they knowingly receive, possess, sell, or unlawfully operate an automobile, airplane, motorcycle, motorboat, or other motor-propelled vehicle without the consent of the owner. It is a class D felony, punishable by up to seven years.
The statute does not require proof that the person intended to keep the vehicle. Driving someone else’s car without consent is enough. That is the main difference from stealing.
Related charges
What is the difference between tampering and stealing a car in Missouri?
Intent to deprive, and the stakes for repeat offenses.
Stealing a motor vehicle
Stealing requires the purpose to deprive the owner of the vehicle. Under RSMo 570.030, stealing a motor vehicle is a class D felony regardless of value, and a class B felony for a person with two prior stealing-related offenses within ten years.
Tampering in the first degree
Operating, possessing, receiving, or selling the vehicle without consent, with no requirement of intent to keep it. A class D felony.
Tampering in the second degree
Unlawfully riding in or on someone else’s vehicle, under RSMo 569.090, is a lower-level offense. Passengers are often charged this way, or not at all.
Why it matters
The charge selected affects the class, the possible enhancements, and how the case can be resolved. A driver and a passenger in the same car may face very different charges.
Knowledge
Can I be charged with tampering if I did not know the car was stolen?
The State must prove you knew you lacked the owner’s consent.
Tampering requires that the person acted “knowingly.” Someone who borrowed a car from a friend who said it was theirs, or bought a car in a sale they believed was legitimate, may lack that knowledge.
The statute allows the State, with the court’s permission, to offer two kinds of evidence to prove knowledge: that the person unlawfully received, possessed, sold, or operated a vehicle on a separate occasion, or that they acquired the vehicle for a price they knew was far below its reasonable value. A judge must find that the evidence is more useful than unfairly prejudicial before it comes in.
Defenses
How do you fight a tampering charge in Missouri?
Consent, knowledge, and who was actually driving.
- Consent. Permission from the owner, or from someone the person reasonably believed could give it, is the central issue in many cases, especially between family members, partners, and roommates.
- Knowledge. The person must have known the use was without consent.
- Operation and possession. Being near or inside a vehicle is not the same as operating or possessing it. Who had the keys and who was driving matter.
- Ownership disputes. Unpaid sales, title problems, and shared vehicles can turn a civil dispute into a criminal charge that does not fit.
- The stop. Many of these cases begin with a stop based on a stolen-vehicle alert. Whether the stop and any search were lawful can matter.
FAQ
Tampering questions
Is tampering with a motor vehicle a felony in Missouri?
Yes. Tampering in the first degree, including operating or possessing a vehicle without the owner’s consent, is a class D felony under RSMo 569.080, punishable by up to seven years.
Is borrowing a car without permission a crime in Missouri?
It can be. Knowingly operating someone else’s vehicle without their consent is first degree tampering, even if you intended to return it.
What happens if I was only a passenger?
Unlawfully riding in another’s vehicle is second degree tampering, a lower-level offense, and a passenger who did not know the car was taken without consent may not be guilty of anything.
Can a tampering charge be reduced?
Sometimes, depending on the evidence of consent and knowledge, the person’s record, and the owner’s wishes. An SIS or a reduction may be realistic in some first-offense cases.
Can first degree tampering be expunged in Missouri?
Many class D felonies can be expunged after the waiting period if the rest of the record qualifies. Eligibility depends on the full history.
