Kern County DUI defense.
How DUI cases move through the Kern County Superior Court, the DMV process for Central Valley APS hearings now conducted virtually, and the particular considerations for oil industry workers, agricultural workers, and the I-5 corridor between LA and the Central Valley.
The Kern County Superior Court
The Kern County Superior Court hears DUI cases primarily at the main Kern County Justice Center in Bakersfield, with regional branch courts in Delano, Lamont, Mojave, Ridgecrest, and Shafter handling cases from their respective areas. The Bakersfield courthouse handles felony criminal cases and the main DUI calendar.
Kern County's DUI calendar moves at moderate pace with arraignments typically within 30 to 45 days. The court reflects the demographics of the southern San Joaquin Valley: oil industry employees, agricultural workers, military personnel from Edwards AFB and China Lake, and a substantial Hispanic population.

Cases originating in Bakersfield, Oildale, Lake Isabella area, Tehachapi (eastward), and Arvin arraign at the Bakersfield Justice Center. North county cases (Delano, McFarland, Wasco) arraign at Delano. East desert cases (Mojave, California City, Boron) arraign at Mojave. Ridgecrest and the Indian Wells Valley (China Lake area) arraign at Ridgecrest.
The DMV hearing for Kern County arrests
The Department of Motor Vehicles handles the suspension of your driving privilege through an Administrative Per Se (APS) proceeding that runs entirely separate from the criminal court case. Under California Vehicle Code §13558, you have ten calendar days from the date of arrest to request the APS hearing or your license is automatically suspended thirty days after the arrest.
DMV Driver Safety hearings now conducted virtually for Kern County
The Bakersfield Driver Safety Office consolidated as part of the DMV's transition to virtual operations; hearings are now routed through Sacramento or Van Nuys administratively
Phone: (833) 543-7703 (statewide Driver Safety line)
Hours: Mon, Tue, Thu, Fri 8:00am,5:00pm; Wed 9:00am,5:00pm
Kern County APS hearings are conducted virtually via Microsoft Teams as of late 2024. Administrative routing is through Sacramento or Van Nuys depending on the arrest location. The statewide scheduling line is (833) 543-7703.
As of late 2024, most APS hearings are conducted virtually through Microsoft Teams. The hearing officer, the DMV's evidence package (typically the DS-367 sworn report plus the chemical test record), and your attorney all join remotely. You generally do not need to be physically present, and in most cases your attorney will advise you not to attend so that you cannot be compelled to testify against your own interest. Read the full DMV 10-day hearing guide for procedural detail.
How DUI cases are handled in Kern County
The Kern County District Attorney's Office handles DUI prosecutions through dedicated deputies at each courthouse. The office has historically taken a firm position on DUI cases, with disposition outcomes that often require defense counsel to have filed suppression motions or chemical test challenges before reductions are considered.
Standard first-offense dispositions in Kern County run three to five years of summary probation, the appropriate DUI program (3-month or 9-month based on BAC), fines and assessments commonly totaling $2,000 to $3,500, and a court-ordered license suspension. Refusal allegations carry the one-year APS suspension and often add 48 hours of jail time at sentencing.
Wet reckless reductions are obtainable where the BAC is borderline, where the stop has constitutional weaknesses, or where chemical test issues are documented. The regional branch courts sometimes have somewhat more flexibility than the main Bakersfield calendar.
The Kern DA's Office has been particularly active in Watson murder prosecutions and DUI causing injury cases under §23153.
The county's substantial Spanish-speaking population creates frequent language-barrier issues in Trombetta admonishments. Defense counsel familiar with these issues produces materially better outcomes.
Military service members from Edwards AFB (technically just over the LA County line but with substantial Kern County presence) and China Lake Naval Air Weapons Station face parallel UCMJ proceedings independent of the civilian case.

Cities and communities in Kern County
Kern County is California's twelfth most populous county and the southern gateway to the San Joaquin Valley. The county includes eleven incorporated cities and substantial unincorporated populations.
Substantial unincorporated populations exist in Oildale (adjacent to Bakersfield), Lake Isabella (in the Sierra foothills), Lebec and Frazier Park (in the Tehachapi Mountains), Boron and Edwards (near Edwards AFB), and Rosamond. The California Highway Patrol handles freeway arrests on Interstate 5, Highway 99, Highway 58, Highway 14, and Highway 178.
DUI scenarios specific to Kern County
Kern County DUI arrests pattern around the major freeway corridors and the regional economy.
The Interstate 5 corridor through the Grapevine and Lebec areas generates substantial DUI cases from drivers traveling between Southern California and the Central Valley. CHP patrols this corridor intensively. Stops in the Grapevine (Tejon Pass) area can result in transport to Bakersfield for booking, creating significant timing arguments due to the distance.
The Highway 99 corridor through Bakersfield, Delano, and McFarland generates significant local DUI volume.
Oil industry workers in Bakersfield, Taft, Maricopa, and the Kern County oil fields face DOT medical certification requirements and employer policies that can be affected by DUI arrests. Field workers, drilling crews, and tanker drivers face specific concerns.
Agricultural workers in the dairy industry (Delano, McFarland, Shafter) and the produce industry (Arvin, Lamont) face language-barrier and work-schedule considerations.
Edwards Air Force Base personnel face parallel UCMJ proceedings on DUI arrests, with command action under Article 15 potentially preceding the civilian case.
China Lake Naval Air Weapons Station personnel (Ridgecrest area) face similar parallel proceedings, with cases handled at the Ridgecrest Branch Court.
Sobriety checkpoints in Bakersfield, Delano, and the smaller cities are conducted regularly. Constitutional compliance challenges are productive.
Lake Isabella recreational DUI in summer months includes boating-while-intoxicated cases under Harbors and Navigation Code §655.
Defenses that often apply in Kern County cases
Defenses commonly viable in Kern County DUI cases:
Language barrier defenses on the Trombetta admonishment are productive given the substantial Spanish-speaking population.
Stop challenges are productive on the I-5 Grapevine corridor where stops sometimes cite vague observations.
Title 17 challenges apply to breath testing instruments.
Rising BAC arguments work in cases with significant delay between driving and chemical testing, common in Kern County's long transports from rural areas.
Field sobriety test challenges are productive where tests were administered on uneven surfaces or in adverse conditions (dust, heat, cold). The Tehachapi Mountains and the desert areas frequently produce these conditions.
Military-specific defenses apply in Edwards AFB and China Lake service member cases.
The first 72 hours after a Kern County DUI arrest
The first three days after a Kern County DUI arrest are decisive.
- Locate the pink temporary license from booking. The ten-day APS clock runs from arrest.
- Identify the courthouse from your citation.
- Military and oil industry workers: review employer notification policies.
- Spanish-speaking defendants: ensure interpreter access and consider Spanish-language counsel.
- Preserve evidence. Receipts, text messages, work shift logs if employment-relevant.
- Do not discuss the case with anyone other than counsel.
- Request the APS hearing through (833) 543-7703.
- Identify your arraignment date. Counsel can appear under §977.
Frequently asked questions, Kern County
I am an oil field worker with a CDL. How does a Kern County DUI affect my job?
CDL holders face the 0.04% commercial DUI threshold even when driving personal vehicles. Any DUI conviction triggers federal CDL disqualification under FMCSA regulations, one year for first offense, longer for subsequent offenses or hazmat-related conduct. DOT medical certification can be affected. Employer policies typically require self-reporting from arrest, not conviction. Tanker drivers, hazmat haulers, and oil field service drivers face particular exposure.
I'm at Edwards AFB. How does my unit find out?
Kern County and adjacent county agencies notify Edwards AFB of service member arrests through established procedures, typically within 24-72 hours. Your unit and security forces will receive a report. You are expected to self-report; failure to self-report is treated more seriously. Command action under the UCMJ can occur before the civilian case resolves. Base access restrictions and security clearance suspension are common immediate consequences. Coordinate with the Edwards Area Defense Counsel and civilian counsel.
I-5 Grapevine, does the stop location create extra defenses?
Grapevine stops often involve long transport distances to booking facilities in Bakersfield, which creates rising BAC arguments. The mountain altitude can affect breath testing accuracy. Weather conditions (fog, snow, wind) at the Tejon Pass can affect field sobriety test administration. The stop basis is often weave or speed-related observations across long sight lines, which can be challenged.
Lake Isabella boating BUI, how serious?
Boating under the influence is prosecuted under Harbors and Navigation Code §655 and carries similar BAC thresholds and penalties to vehicular DUI. The DMV consequences (license suspension) apply even though the offense was on water. Combined boating-and-driving cases (you boated, then drove home) can involve multiple counts.
Does Kern County have a DUI court?
Kern County operates DUI accountability programs through probation. Eligibility is fact-specific and focused on repeat offenders and those with co-occurring substance use disorders.
