California Vehicle Code Section 23152(f) makes it unlawful to drive a motor vehicle while under the influence "of any drug." Unlike California DUI alcohol laws, which presume that your ability to drive is impaired if you have a blood alcohol concentration of .08 or greater, there is no "per se" drug amount that automatically presumes that you are DUI. However, if a police officer believes that your mental abilities are impaired and that you cannot drive with the same caution of a sober person using ordinary care under similar circumstances, you will be arrested for DUI. Illegal drugs that commonly lead to DUI arrests include cocaine, methamphetamine, and heroin. It can also include legal drugs which a person does not have a valid prescription for. Any drug that causes drowsiness, impaired coordination, impaired judgment, or sleep driving can lead a police officer to believe that your ability to drive is impaired and to place you under arrest for DUI. The penalties for a DUI involving drugs ("DUID") are the same as they are for a DUI involving alcohol. In addition to potential penalties for DUI, a person may also be charged with both Health & Safety Code Section 11550(a), being under the influence of a controlled substance, and, if they were in possession of any illegal drugs or legal drugs without a valid prescription, Health & Safety Code Section 11377(a), possession of a controlled substance.
Evidence Against You in DUI Drugs Cases
If a driver is detained on suspicion of Driving Under the Influence of drugs, and the arresting officer has ruled out alcohol as the sole cause of impairment, for example if the driver submits to a Preliminary Alcohol Screening Test which results in a reading of 0.00%, the officer will call for the assistance of a Drug Recognition Expert, also called a Drug Recognition Evaluator (DRE). The DRE begins his investigation by interviewing the arresting officer about what signs and symptoms he observed that led the officer to believe the person is under the influence of drugs. The DRE will then interview the driver, asking he or she if they have taken any drugs and recording specific observations of the person. This is usually followed up by administering the standardized FST's that are used during a DUI investigation, the most common being the Horizontal Gaze Nystagmus (HGN), the Walk-and-Turn (WAT), and the One-Leg Stand (OLS) tests. Visit our DUI BLOG for a detailed discussion of FST's.
Following the field sobriety tests, the DRE will conduct a vital signs examination, checking the person's blood pressure and body temperature, as well as a dark room examination, using a pupilometer and pen light, to estimate the person's pupil size in specific lighting situations. This is followed up by a muscle tone examination and a check for injection sites caused by hypodermic needles. The DRE analyzes all of the signs and symptoms observed and recorded to form an opinion as to whether the person is under the influence of drugs. The final step is for the DRE to request the person to submit to a blood test to obtain evidence of drug use. All of the DRE's observations, as well as the results of the blood test, will be used by the prosecution in court against the driver to prove that they were DUI.
Drug Charges In Addition to DUI
If you are arrested for DUI involving illegal drugs, you could also face additional criminal charges. The officers may search your car looking for evidence of drug use. If they find prescription drugs that are prescribed in your name, or illegal drugs of any kind, you could face additional criminal charges, such as possession of a controlled substance and being under the influence of a controlled substance. If the quantity of drugs was large enough you could even face a possession for sales charge, which is a felony.
Consultation With Experienced DUI Lawyer
Drug DUI cases are difficult for the prosecution to prove. Although a blood test can show whether or not a person has used a particular illegal drug, it cannot confirm when the drug was used. The effect may have worn off well before the person drove a vehicle. Do not assume you are guilty because you have been arrested for DUI drugs. The presence of illegal drugs in the body alone is not enough to prove a person is guilty of DUI beyond a reasonable doubt.
