How They Prove A Suspect Is Driving Under The Influence Of A Drug – CVC 23152 (a)

A common question when facing allegations of driving under the influence of drugs (CVC 23152(a)) is, how does the prosecution prove that a suspect was “under the influence” of a narcotic? Proving that a defendant was under the influence of a drug requires proving that the substance involved impaired driving. It is important to know that it is not a defense to the charge that the defendant had a prescription or otherwise legally used an over-the-counter, non-prescription drug.

DUI Prosecution

For a conviction based in whole or part on drug use, two general elements must be met:

(1) The drug must be a substance or combination of substances other than alcohol that can impair driving to an appreciable degree; AND

(2) It must be proved that the defendant was in fact impaired by that drug.

Simply being “impaired” may not be enough to sustain a conviction. The level of impairment must be “appreciable.”
