The short answer is YES.  The definition of "under the influence" is not limited to just alcohol, but also includes any substance that impairs a person's ability to operate a vehicle safely, including illegal drugs, prescription medications, and over-the-counter medications.

Law enforcement officers are trained to look for signs of impairment during traffic stops, such as slurred speech, bloodshot eyes, poor balance or coordination, and erratic driving behavior.  If an officer suspects that a driver is impaired by the use of drugs, they may conduct field sobriety tests or request a chemical test, such as a blood or urine test, to determine the presence of drugs in their system.  A specially trained officer called a drug recognition examiner (DRE) may be called to the scene to assist in the investigation.  You can read more about DUI's involving drugs and prescription drugs/medications on our website.  

It is important for all drivers, even those who do not drink alcohol, to be aware of the potential effects of any medications they are taking and to avoid driving if they feel impaired.  "Impairment" is best defined as the diminishment or loss of function or ability.  A driver can be arrested for DUI if their ability to drive safely is impaired.  

DUI cases involving drugs or medications are often complicated and much more difficult for the prosecution to prove a person is guilty.  Call our office today at (877) 667-1205 or submit the CONTACT form if you were arrested for DUI involving drugs or medications.
