Wisconsin Drugged Driving

A person is guilty of DUI in Wisconsin if a motor vehicle operator is under the influence of an intoxicant to the degree that he or she is incapable of driving safely; OR a person drives or operates a motor vehicle with a detectable amount of a restricted controlled substance in their blood*. Wis. Stat. Ann. §§ 346.63 (1)(a)-(am) (West 2010). *driving with detectable restricted controlled substance in blood(per se law) Id. § 346.63 (1)(am).

Wisconsin DUI law prohibits any controlled substance other than THC and associated inert metabolites. However, Wisconsin does test for Delta-9- THC, an active ingredient in cannabis which passes through the body much faster than do other inert metabolites of cannabis.

Affirmative Defense

A valid affirmative defense exists if at the time of the incident or occurrence, violator had a valid prescription for substance. Id. § 346.63(1)(d).

NOTE: Physicians recommendation to use cannabis is NOTa prescription.

  • Prior to arrest, an officer may request a breath sample for preliminary screening. The result can be used deciding whether a person should be arrested for DUI.
