Drug DUI Defense Attorney Assisting Clients Facing Charges In Clayton

Driving under the influence of drugs (DUID) in Clayton, Missouri, carries similar penalties and consequences as driving under the influence or while intoxicated (DUI/DWI) charges. If you need help understanding, I can break down the state’s laws.

At The Civella Law Firm, my goal is to provide you with a full scope of what is at stake when you are under investigation for DUID. With my guidance, we can create a defense strategy that targets loopholes in a prosecutor’s case.

What Counts As Drug-Impaired Driving In Clayton

Clayton treats DUID cases the same way as driving while intoxicated (DWI) offenses. You can face a DWI charge for driving while impaired by an illegal substance, cannabis or a prescription drug. The courts focus exclusively on whether the drug impaired your driving ability, which is why there is no statutory per se limit for substances.

Moreover, the drug DUI penalties are the same as a DWI charge:

  • Class B misdemeanor: Up to six months in county jail and up to $1,000 in fines
  • Class A misdemeanor: Up to one year in county jail and up to $2,000 in fines
  • Class E felony: Up to four years in state prison and up to $10,000 in fines

DUID cases in Clayton also have to go through Missouri’s dual legal tracks. Your arrest triggers criminal and administrative law actions. This means you can face court sentencing, added points to your driving record and automatic license suspensions or revocations by the state.

Factors That Police Consider For Suspected Drug Impairment

The municipal courts in St. Charles County that are heavy DWI arrest areas are: City of St. Peters, City of O’Fallon and the City of St. Charles. When police officers notice impaired behavior while driving, they often resort to stopping and asking you to perform field sobriety tests (FSTs). If they find clues in your performance, they may use this to build a probable cause to formally arrest you.

Besides FSTs, officers may seek help from drug recognition experts (DREs) to evaluate suspected drug use. They conduct a 12-step evaluation through an interview and assessment of your pulse, eye and muscle tone. Officers can ask you to take chemical testing to detect drug compounds and metabolites.

How DUID Cases Differ From Alcohol-Related DWIs

Drugs react differently compared to alcohol. Traces of a substance can remain detectable in your blood or urine for days or weeks after psychoactive effects have ended. If a drug substance is present in a lab result, this is insufficient to establish impairment at the time of driving. The state must prove that the active drug was actively impairing cognitive or motor functions while behind the wheel.

Defending a drug-related DUI involves challenging police procedures and scientific evidence. DUID defense strategies focus on exposing subjective DRE evaluations prone to misinterpreting medical issues, questioning chemical test accuracy and suppressing evidence if the initial traffic stop lacked probable cause.
