When people think of a DUI charge they think of drinking and driving. When they think of a drugged driving charge, they usually think of illegal drugs and driving – but what about prescription drugs?
In Wisconsin, it is illegal to operate a motor vehicle while under the influence of alcohol, or with any amount of illegal drugs in your system, or while impaired by prescription drugs.
The Wisconsin statute (363.63(a)) specifies the following as prohibited conduct: Driving under the influence of an intoxicant, a controlled substance, a controlled substance analog or any combination of an intoxicant, a controlled substance and a controlled substance analog, under the influence of any other drug to a degree which renders him or her incapable of safely driving, or under the combined influence of an intoxicant and any other drug to a degree which renders him or her incapable of safely driving.
Drugs that often come up are Ambien, muscle relaxants, pain killers, and stimulants. You can receive an DUI for taking drugs that it is legal for you to take! (You can also get a DUI for using alcohol that it is legal for you to consume.)
The testers used by the state often report their results in terms of “therapeutic levels.” This has nothing to do with impairment or the lack thereof.
See this Monograph by the Utah Department of Hygiene explaining why the won’t do testing for the quantity of a drug, just the presence or absence of the drug.
