What Is Driving While Impaired by a Controlled Dangerous Substance?

Under Maryland law, a person is guilty of driving while impaired by a controlled dangerous substance if the State proves:

  1. That the defendant drove, operated, or was in actual physical control of a vehicle; and
  2. That, at the time, the defendant was impaired by a controlled dangerous substance.

 

Impairment exists when the substance has reduced the person’s normal coordination to some extent. Importantly, if you were lawfully entitled to use the controlled dangerous substance (for example, under a valid prescription or Maryland’s medical cannabis laws), that entitlement can serve as a complete defense — unless you were unaware that the substance would impair your ability to drive safely.

Penalties for Driving While Impaired by CDS in Baltimore County

A conviction under § 21-902(d) is a misdemeanor with serious consequences:

  • First offense: Up to 1 year in jail and/or a fine of up to $1,200.
  • Second offense: Up to 2 years in jail and/or a fine of up to $2,400.

 

Penalties increase significantly if a minor was in the vehicle. Convictions also trigger mandatory license suspension, ignition interlock requirements, points on your driving record, and higher insurance premiums. Repeat offenders face enhanced mandatory minimum sentences.

Strong Defenses to Driving While Impaired by CDS Charges

At Shepard Law, we carefully examine every aspect of the State’s evidence to build a thoughtful defense strategy tailored to your situation. Common and effective defenses include:

  • Lawful entitlement to use the controlled dangerous substance (prescription or medical cannabis defense)
  • Insufficient evidence of actual impairment
  • Challenges to the reliability or admissibility of chemical tests or field sobriety tests
  • Unlawful traffic stop or lack of probable cause
  • Medical conditions or other factors affecting coordination or test results

 

Stephen P. Shepard approaches each case with care and attention, working closely with clients to pursue the most appropriate resolution—whether through dismissal, reduction of charges, or trial.
