A person may be charged with DWI if they are:

A person may be charged with DWI (Driving While Intoxicated) if they are under the influence of both alcohol and controlled dangerous substances (CDS). This is because DWI laws are designed to encompass impairment from any substance that can affect a driver's ability to operate a vehicle safely.

The law recognizes that both alcohol and drugs can impair judgment, coordination, and reaction times, leading to unsafe driving conditions. Therefore, being influenced by one or both substances can result in a charge.

In this context, the possibility of being charged for either substance individually underscores the law's broad scope. However, being under the influence of both substances simultaneously represents a particularly acute risk and is therefore explicitly recognized within DWI regulations, making this scenario the most comprehensive coverage of the law.
