Minnesota's Drugged Driving Law

Learn about the laws and penalties for driving under the influence of drugs (DUID) in Minnesota.

By , Attorney

Driving while impaired (DWI) (sometimes called "DUI") is most often associated with driving under the influence of alcohol. But the law also prohibits "drugged driving"—that is, driving under the influence of drugs or hazardous substances.

This article discusses how Minnesota defines drugged driving and the consequences of a violation.

Drugged Driving Defined

A Minnesota motorist can be convicted of a drug DWI for driving, operating, or being in physical control of a motor vehicle while:

  • under the influence of a "controlled substance"
  • knowingly under the influence of a "hazardous substance" that affects the body and substantially impairs driving abilities, or
  • having any amount of a schedule I or II controlled substance (except marijuana) in the body.

A driver is considered "under the influence" if he or she doesn't "possess that clearness of intellect and control" that he or she otherwise would.

Controlled substances. For purposes of Minnesota's DWI laws, "controlled substance" means any substance listed in schedules I through V of the state's Controlled Substances Act. The list is extensive and includes opiates, hallucinogens, depressants, narcotics, and marijuana.

Schedule I and II controlled substances. The list of controlled substances in schedules I and II—the subset of drugs that Minnesota law prohibits for drivers in any amount—contains substances such as:

  • heroin, LSD, and ecstasy on schedule I, and
  • methadone, oxycodone, morphine, codeine, methamphetamine, and cocaine on schedule two.

Defendants who are charged for driving with a schedule I or II drug in their system have a defense if they can show that the drug was being used pursuant to a valid prescription. However, the defense doesn't apply if the driver is charged for driving under the influence of the drug (as opposed to just having a concentration of the drug in the blood).

Marijuana. Marijuana is a schedule I controlled substance, but it's excluded from the zero-tolerance rule that applies to all other schedule I and II drugs. However, it's still illegal to drive under the influence of marijuana.

Hazardous substances. "Hazardous substances" are defined by Minnesota's Administrative Rules. The list includes some common household products, such as aerosol sprays and paint thinners, which can be inhaled (or huffed) to produce a high. Recently, a Minnesota court held that compressed gas from a can of "Dust-Off" (used to clean electronics) was a hazardous substance under the DWI statute.

Consequences of Drugged Driving

A driver arrested for drugged driving in Minnesota will be charged with a DWI. The same DWI penalties that apply to drunk driving also apply to drugged driving. Likewise, a drugged driving incident is considered a prior offense for future DWI sentencing.

The specific penalties for a first, second, and third-offense DWI in Minnesota depend on the circumstances of the case.
