Driving under the influence (DUI) is often associated solely with alcohol consumption. However, drug-impaired driving has become increasingly recognized as a serious offense. Understanding the distinctions between DUI and DUID (driving under the influence of drugs) is important, particularly in legal contexts where the nature of the impairment can significantly influence charges, legal strategies, and outcomes.
Here are five key differences between DUI and DUID that every driver should be aware of:
One major distinction lies in how the law defines each offense. In California, for example, DUI laws are outlined in California Vehicle Code Section 23152. DUI involving alcohol is addressed under subsections 23152(a) and (b). In contrast, DUID is specifically addressed under subsection 23152(f) for drug impairment and subsection 23152(g) for combined alcohol and drug impairment. These provisions reflect the legal system’s intent to handle alcohol- and drug-related driving offenses separately.
DUI charges generally involve alcohol, which has a legally established blood alcohol concentration (BAC) threshold. DUID charges, on the other hand, can involve a broad range of substances. These include illegal drugs, marijuana, prescription medications, and even over-the-counter medications. Any substance that impairs a person’s ability to operate a vehicle safely may result in a DUID charge, regardless of whether the substance is legal or commonly used.
Alcohol impairment is typically measured using a Breathalyzer, which provides immediate and quantifiable BAC results. Detecting drug impairment, however, is more complex. Officers often rely on blood or urine tests to detect the presence of drugs. Unlike alcohol, there is no standardized measurement that conclusively indicates impairment for drugs. This lack of a consistent threshold complicates both the detection and prosecution of DUID cases.
DUI defense strategies usually focus on challenging the accuracy or admissibility of BAC results. In DUID cases, the absence of a universal standard for drug impairment introduces additional legal challenges. Defense arguments may question the reliability of the drug test, the officer’s observations, or the interpretation of symptoms. These complexities often make the legal process more involved when dealing with drug-related charges.
Prosecuting DUI cases often relies on BAC readings and standardized field sobriety tests. In DUID cases, prosecutors may need to depend more heavily on circumstantial evidence, laboratory results, and the observations of law enforcement officers. Expert testimony is also more commonly used in DUID cases due to the lack of established impairment benchmarks. As a result, DUID prosecutions can be more challenging and offer additional avenues for legal defense.
