Can prescription drugs lead to DWI charges in Maryland?

On Behalf of | Apr 3, 2025 | Criminal Defense

When most people hear “DWI or DUI”, they think of alcohol or illegal drugs. However, in Maryland, driving under the influence of prescription medication can also lead to legal charges. 

Below are some important points to remember about taking prescription drugs and driving. 

Some prescription drugs can impair your ability to drive

Many prescription medications warn about drowsiness, dizziness or slowed reaction times. Drugs used to treat anxiety, pain, sleep issues or allergies can all affect how alert you are behind the wheel.

If a drug affects your driving ability, Maryland law takes it seriously. Even if the medication was legally prescribed, you can be charged with Driving While Impaired (DWI) or Driving Under the Influence (DUI) if you are not in full control of your vehicle.

The law in Maryland 

Maryland Transportation Code § 21–902 makes it illegal to drive while impaired by any drug, whether legal or illegal. The law focuses on the effect the substance has on your ability to operate a vehicle.

Officers can arrest you based on driving behavior, field sobriety tests or statements you make. 

What are the penalties for driving under the influence of prescription drugs?

Penalties for a DWI or DUI in Maryland may include:

  • Fines
  • Jail time
  • License suspension
  • Points on your driving record
  • Mandatory treatment or education programs

These penalties can apply even if you used the medication exactly as prescribed. If your doctor prescribes a new medication, you should ask how it might affect your driving. Even using legal drugs can result in criminal charges. 

If you have been charged with DWI in Maryland for prescription drug use, that doesn’t automatically mean guilt. You can challenge the case against you. Seeking legal guidance will help you to do this.
