DUID Attorney in San Bernardino

Former Prosecutors Defending Drug DUI Charges Throughout San Bernardino County

A drug DUI charge under California law is prosecuted differently than an alcohol DUI. There’s no breath test, no per se limit, and the prosecution’s case often rests on subjective field observations and chemical evidence that can be challenged. Newman & Allen has represented individuals facing DUI-related charges through San Bernardino County Superior Court since 1996, and we understand how these cases are built and where they can be attacked.

Former Prosecutors Who Know How the DA Builds These Cases

Attorneys Geoff Newman and JC Allen are both former prosecutors with more than 40 combined years of legal experience. That background gives us direct insight into how the San Bernardino County District Attorney’s office evaluates and builds drug impairment cases. We know what prosecutors look for, where the evidence is thin, and how these cases are typically argued.

We don’t treat every case the same. Drug DUI charges vary widely depending on the substance involved, the officer’s observations, how the blood draw was handled, and whether a Drug Recognition Expert was used. Your defense should reflect your specific situation, not a standard playbook.

What the Law Says: VC 23152(f) & 23152(g)

California Vehicle Code 23152(f) makes it unlawful to drive under the influence of any drug, including illegal drugs, prescription medication, over-the-counter medication, and cannabis. Vehicle Code 23152(g) covers driving under the combined influence of alcohol and a drug. Both are commonly referred to as DUID charges.

Unlike an alcohol DUI, there’s no 0.08% equivalent for drugs. The prosecution must prove the driver’s ability to drive safely was actually impaired. A valid prescription or legal recreational marijuana use isn’t a defense on its own. Under CALCRIM 2110, the jury instruction that defines impairment, a “drug” includes any substance other than alcohol that could appreciably impair a person’s ability to drive with the caution of a sober person.

Because breath tests don’t detect drugs, DUID investigations typically rely on blood or urine testing and often involve a Drug Recognition Expert (DRE), an officer trained to use a standardized 12-step evaluation protocol to assess impairment.

Penalties for a DUID Conviction in San Bernardino

A first-offense DUID is usually charged as a misdemeanor. A felony charge applies when the driver has three or more prior DUI convictions within 10 years, a prior felony DUI conviction, or caused injury to another person.

First Offense

First offense penalties include:

• Up to 6 months in jail
• Fines and assessments exceeding $3,000
• Mandatory 3-to-9-month DUI school
• A possible ignition interlock device requirement of up to 6 months under AB 366, though installation isn’t always mandatory for a drug-only DUID conviction

Second & Third Offense

Second and third offense penalties include:

• Mandatory jail time ranging from 96 hours for a second offense to 120 days for a third offense, up to 1 year
• An 18-month DUI school for a second offense, or a 30-month DUI school for a third
• Longer ignition interlock device requirements

Felony DUID & Collateral Consequences

A felony DUID carries 16 months to 3 years in state prison. Prior DUI convictions remain “priorable” for 10 years, meaning any new arrest within that window triggers significantly higher penalties. Collateral consequences can include an SR-22 insurance filing, loss of a commercial driver’s license, and disqualification from certain professional certifications.

Challenging the Evidence in a Drug DUI Case

The absence of a per se drug limit creates real defense opportunities. Drug metabolites in a blood or urine sample show prior use, not necessarily impairment at the time of driving. The prosecution has to bridge that gap, and that’s often where the evidence is most vulnerable.

Common defense angles in DUID cases include:

• DRE testimony: The Drug Recognition Expert’s training, certification, and specific observations during the 12-step evaluation can be challenged through cross-examination
• Chemical test reliability: Lab handling, storage, and testing procedures affect the validity of blood and urine results
• Blood split motion: California law requires that a portion of a DUI blood draw be preserved for up to one year so the defense can request independent retesting
• Medical or physical factors: Conditions unrelated to drug use can affect field sobriety performance and how a driver appears to an officer

The DMV Hearing Deadline After a DUID Arrest

A DUID arrest in San Bernardino opens two separate cases: one in criminal court and one with the California DMV. These proceed on independent tracks, and the DMV case moves fast. If you don’t request a DMV hearing within 10 days of your arrest, your license may be automatically suspended regardless of what happens in the criminal case.

Having a DUID lawyer manage the DMV administrative hearing alongside the criminal defense is important to protecting your ability to drive while the case is pending.

Steps to Take After a Drug DUI Arrest

What you do in the days following an arrest matters. Keep all paperwork from the arrest, including your citation, temporary license, and release documents. Write down everything you remember about the stop, the officer’s observations, and any testing while the details are still fresh. Avoid discussing the case on social media or with anyone other than a lawyer and close family. Note any medical conditions, injuries, or other factors that may have affected how you appeared or performed on field sobriety or chemical tests.
