According to[4]NHTSA data[4], 67% of alcohol-impaired driving fatalities in 2023 involved drivers with BACs of 0.15 g/dL or higher

The Two-Case System: Criminal Court + DMV Hearing
Most people don’t realize a DUI arrest creates TWO separate legal proceedings:
1. Criminal Case (Superior Court)
Prosecuted by: San Bernardino County District Attorney’s Office Determines: Guilt or innocence on criminal charges Penalties: Jail, fines, probation, DUI school, criminal record Standard: Proof beyond reasonable doubt Your rights: Right to attorney, right to jury trial, presumption of innocence
2. DMV Administrative Per Se (APS) Hearing
Conducted by:[9]California Department of Motor Vehicles[9]
Determines: Whether your license will be suspended
Issues: (1) Did officer have cause to stop/arrest? (2) Were you lawfully arrested? (3) Was BAC 0.08%+ or did you refuse test?
Standard: Preponderance of evidence (lower than criminal standard)
Deadline: Must request hearing within 10 days of arrest
CRITICAL: These are completely separate proceedings. Winning your DMV hearing doesn’t dismiss criminal charges (and vice versa). You need defense for BOTH.
Why DMV Hearing is Critical
If you don’t request hearing (or lose hearing):
Automatic license suspension begins
First offense: 4 months (or 1 year if refused test)
Can’t drive at all during suspension unless you get IID-restricted license
If you win DMV hearing:
No administrative suspension
License remains valid (though court can still suspend upon conviction)
Early discovery of prosecution’s evidence
Strategic value:
DMV hearing occurs BEFORE criminal trial
We get to cross-examine arresting officer under oath
Officer’s testimony locked in, can be used against them in criminal case
We obtain police reports, test results, and other evidence early
Often reveals weaknesses we can exploit in criminal case
Common DUI Defenses
Every DUI case is different. At Tu Defensor Criminalista, we thoroughly investigate your arrest and build a defense strategy tailored to the specific facts of your case.
Illegal Traffic Stop
The Law: Fourth Amendment prohibits unreasonable searches and seizures. Officers must have reasonable suspicion to stop your vehicle.
Invalid reasons for traffic stops:
“Driving through high-crime area”
Anonymous tip without corroboration
Hunch or intuition
Racial profiling
Valid reasons:
Traffic violations (weaving, speeding, running red light, broken taillight)
Equipment violations
Observed dangerous driving
Defense strategy: If stop was illegal, ALL evidence obtained afterward (including breath/blood test results) must be suppressed under the “fruit of the poisonous tree” doctrine. Case dismissed.
No Probable Cause for Arrest
The Law: Officers must have probable cause to arrest you for DUI. Reasonable suspicion (sufficient for traffic stop) is not enough for arrest.
What prosecutors must prove:
Totality of circumstances supported reasonable belief you were DUI
Evidence includes: driving pattern, physical symptoms, field sobriety test performance, admission, BAC test
Defense strategy: Challenge sufficiency of evidence supporting arrest. If arrest was unlawful, chemical test results may be suppressed.
Inaccurate Breathalyzer Results
Breathalyzer machines are scientific instruments that require proper calibration, maintenance, and operation. Many factors can produce false high readings:
Machine Not Properly Calibrated:
California Code of Regulations Title 17 requires breath machines be checked every 10 days and calibrated every 150 days
Maintenance records often reveal missed calibrations
15-Minute Observation Period Not Followed:
Title 17 requires officer observe you continuously for 15 minutes before breath test
Ensures no mouth alcohol contamination from burping, vomiting, or regurgitation
Defense strategy: Challenge officer’s training, administration, and interpretation of tests.
Checkpoint Violations
DUI checkpoints are legal in California, but must follow strict guidelines:
Required:
Supervisory decision on location/procedures
Neutral mathematical formula for stopping vehicles
Adequate safety precautions
Reasonable detention time
Visible indicia of official nature
Advance publicity
Defense strategy: If checkpoint doesn’t comply with all requirements, stop is illegal and evidence suppressed.
Frequently Asked Questions About DUI in San Bernardino County
What should I do immediately after a DUI arrest?
(1) Request a DMV hearing within 10 days, (2) Don’t make any statements to police beyond identifying information, (3) Write down everything you remember about the stop and arrest, (4) Contact an experienced DUI attorney immediately.
Can I refuse a breathalyzer or blood test?
You can refuse, but consequences are severe: automatic 1-year license suspension (first offense), mandatory 48 hours jail, and prosecution will use refusal as evidence of guilt. California’s “implied consent” law means you impliedly consented to chemical testing when you obtained your license.
How long will a DUI stay on my record in California?
DUI convictions remain on your criminal record permanently unless expunged. For DMV purposes, DUI remains on your driving record for 10 years. This 10-year period is used to determine whether subsequent DUI arrests are charged as second, third, or fourth offenses.
Can I get my DUI expunged?
Yes. Under Penal Code § 1203.4, if you successfully complete probation, you can petition the court to set aside your conviction and dismiss the case. This doesn’t erase the conviction but changes your plea to “not guilty” and dismisses the case. Helpful for employment background checks.
Will I lose my job if convicted of DUI?
Depends on your employer and profession. Commercial drivers (CDL holders) face 1-year disqualification. Healthcare professionals, teachers, lawyers, and others with professional licenses may face discipline. Private employers vary—some terminate for any criminal conviction, others only for job-related offenses.
Can I drive to work during my license suspension?
You may qualify for an IID (Ignition Interlock Device) restricted license that allows you to drive anywhere (including work) with a breathalyzer installed in your vehicle. This is available immediately after arrest if you request it timely.
What’s the difference between DUI and wet reckless?
“Wet reckless” (Vehicle Code § 23103.5) is reckless driving involving alcohol. It’s a common plea bargain in DUI cases. Benefits: lower fines, shorter probation, shorter DUI school, less severe on record. BUT it still counts as a prior DUI if arrested again within 10 years.
How much does a DUI attorney cost?
Legal fees for DUI defense typically range from $2,500-$10,000+ depending on case complexity, whether it’s a felony or misdemeanor, whether it goes to trial, and the attorney’s experience. Many attorneys offer payment plans. The cost of NOT hiring an attorney (losing your license, jail time, higher fines, higher insurance, lost employment) typically far exceeds attorney fees.
Should I just plead guilty?
Never plead guilty without first consulting an experienced DUI attorney. Many DUI cases have strong defenses that result in reduced charges, dismissed charges, or acquittal at trial. Once you plead guilty, you’ve given up all rights and options.
