Minnesota's Drugged Driving Law
Learn about the laws and penalties for driving under the influence of drugs (DUID) in Minnesota.
Minnesota’s drugged driving law is located at Minnesota Statutes Annotated Section 169A.20. The law states that a person shall not drive or be in actual physical control of any moving vehicle while under the influence of a controlled substance, or knowingly under the influence of any hazardous substance that affects the nervous system, brain, or muscles so as to substantially impair the person’s ability to drive or operate the motor vehicle, or “when the person’s body contains any amount of a controlled substance listed in schedule I or II other than marijuana or tetrahydrocannabinols.”
Minnesota has what is known as a per se (also known as a “zero tolerance”) prohibition against drugged driving if the driver, while driving, has any controlled substance in his or her body (other than marijuana). That means that a driver may be arrested if the police officer has a reasonable suspicion that any prohibited drug (other than marijuana) even if it’s just a trace is in the driver's body while the driver is operating the vehicle. Other than the per se/zero tolerance rule, an arrest can be triggered by a driver impaired by drugs although actual evidence of impaired driving is not essential as long as the police officer has a reasonable belief that the driver is on something while behind the wheel.
