Most people think an OWI (Operating While Intoxicated) charge only applies to alcohol. But in Wisconsin, police can also charge you with OWI for driving on legal prescription drugs. This surprises many drivers, who believe a doctor’s prescription makes the medicine safe.
How medications can affect driving
Some prescriptions can make you tired, dizzy or slow to react. These effects can make driving dangerous even when you take the right dose. Wisconsin law does not require the drug to be illegal.
If an officer sees you drive poorly and believes medication causes it, the officer can arrest you for OWI. To convict you, the court must prove that the drug makes you unable to drive safely.
Why you need to take this seriously
Police watch your driving, give field sobriety tests and order blood tests to show that medication affects you. Judges treat a prescription OWI the same way as an alcohol OWI.
You could pay hefty fines, lose your license, pay higher insurance rates or go to jail if you repeat the offense. A prescription does not shield you from legal consequences if the medication hurts your ability to drive safely.
Stay safe and protect yourself
Always read the warning labels on your medicine before you drive. If your doctor or the label warns that a drug can make you sleepy or dizzy, choose another ride. Wait to drive until you learn how the medicine affects your body.
If you face an OWI charge because of medication, speaking with a lawyer who understands Wisconsin OWI cases may help. They can walk you through your choices, explain what actions can protect you and help you plan your next steps with support and clarity.
