Identifying and Training

Substances that are licit, illicit, or over-the-counter, can act on the brain and central nervous system (CNS). These areas of the body, affected by these substances, can affect how you operate a motor vehicle. Knowing what amount of drug you are taking can help determine the effect the drug will have on you ability to drive safely. When driving under the influence of drugs, you don't just put yourself at risk, but you also endanger other drivers on the road, pedestrians, and bikers that may be nearby.

Knowing possible signs of impairment can help you test yourself to see if you are able to operate a motor vehicle safely. Always err on the side of safety and consult your doctor if you have questions about the drugs you are taking.

Law enforcement officers are on the roads to protect you and the public from being victims of drugged drivers.

There is training available for law enforcement officers to help them identify the signs of individuals under the influence of substances other than (or in addition to) alcohol.
Drug Recognition Evaluators have the ability to administer a psychophysical and physiologic evaluation, interpret the observable signs and symptoms, identify seven categories of drugs and recognize their effects, and prepare a narrative drug influence report of a suspected drugged driver. 
DREs provide support for officers during these impaired driving arrests Completing ARIDE and/or DRE training will help with identifying the signs and symptoms that coincide with being under the influence of drugs.
