Charged with Driving Under the Influence of Drugs? Get Help from a Proven Defense Lawyer
Driving Under the Influence of Drugs (DUID) is a serious offense in Fresno and throughout California. The laws regarding DUID are stringent, reflecting the risks associated with drugged driving. In Fresno, any form of drug impairment—whether from prescription medication, over-the-counter drugs, or illegal substances—can lead to a DUID charge. Understanding these laws is crucial to navigating the legal system effectively and protecting your rights.
California Vehicle Code Section 23152 outlines the general prohibition against driving under the influence, while more specific regulations apply to different substances. Police officers employ various methods to determine impairment, including field sobriety tests and chemical tests. However, the intricacies of these tests and the legal procedures involved can be complex, which underscores the importance of having an experienced DUID attorney in Fresno to identify any challenges to the evidence presented against you.
A skilled Fresno DUID attorney can help protect your rights and fight the charges. Call (559) 257-4707 today or contact us online to schedule your free legal consultation and take the first step toward your defense.
What Is a Drug DUI in California?
Under California Vehicle Code § 23152(f), it is unlawful for a person to drive a vehicle while under the influence of any drug. This includes:
- Illicit substances like cocaine, methamphetamine, or heroin
- Prescription medications such as Vicodin, Xanax, or Ambien
- Over-the-counter drugs that impair driving ability (e.g., Benadryl, NyQuil)
- Marijuana—even if legally obtained under state law
Unlike alcohol-related DUI, where a 0.08% BAC establishes per se intoxication, there is no specific threshold for drug impairment. Instead, the arresting officer must rely on observations, field tests, and the opinion of a Drug Recognition Expert (DRE) to determine impairment. A Fresno DUID lawyer scrutinizes these subjective evaluations, often finding inconsistencies that can dismantle the prosecution’s argument.
How Drug DUI Investigations Are Conducted?
Unlike standard DUI cases involving alcohol, drug DUI investigations typically involve more layers. After initial field sobriety tests, an officer may request a DRE evaluation or chemical testing to support the arrest.
Key components of a DUID investigation include:
- Field Sobriety Tests (FSTs): Designed to measure balance, coordination, and divided attention, but often unreliable and influenced by medical conditions or nervousness.
- Drug Recognition Expert Evaluation: A specially trained officer conducts a 12-step protocol, including checking vital signs, muscle tone, eye movement, and pupil size.
- Chemical Testing: Blood or urine samples are analyzed for the presence of controlled substances. Results are used to link the drug to the alleged impairment.
Each step of the process presents an opportunity for error or misconduct. We can evaluate whether procedures were followed properly and whether constitutional rights were violated during the arrest or testing process.
What are the Legal Penalties for Drug DUI in California?
The consequences for a drug DUI conviction are similar to those for alcohol-related DUIs but can vary based on the specifics of the case and any prior convictions. Penalties may include:
- Jail time (ranging from days to years depending on the offense level)
- Fines, court fees, and assessments
- Probation with strict terms
- Mandatory DUI education programs
- Driver’s license suspension
- Installation of an ignition interlock device
- Community service
- Increased insurance premiums
A Fresno drug DUI attorney works to minimize or avoid these penalties altogether, depending on the facts and available defenses.
What are Common DUID Challenges in Fresno?
Fresno’s diverse demographic and economic landscape contributes to the complexity of DUID cases. Common challenges include:
- Substance Misidentification: Not all substances affect every individual to the same extent. Understanding drug interactions and presentation can be pivotal in defense.
- Test Accuracy: The reliability and calibration of chemical testing equipment may be scrutinized as part of an effective defense strategy by a skilled DUID lawyer.
- Subjective Assessments: Field sobriety tests can often rely on subjective judgment, which a skilled attorney can challenge with objective evidence.
Additionally, socio-cultural factors in Fresno might influence the outcomes of DUID cases. Awareness of these factors allows us to build defenses that take into account not just the letter of the law but also community standards and expectations. Furthermore, ongoing education and understanding about new substances or changes in substance availability in Fresno play a vital role in shaping informed and up-to-date defense strategies.
