Solano County DUI defense.

How DUI cases move through the Solano County Superior Court's three courthouses, the DMV process for the I-80 corridor between the Bay Area and Sacramento, and the particular considerations for Travis Air Force Base personnel.

The Solano County Superior Court

The Solano County Superior Court hears DUI cases at three locations. The Hall of Justice in Fairfield (the county seat) handles felony criminal cases and the main DUI calendar. The Vallejo Hall of Justice handles cases originating in Vallejo and Benicia. The Vacaville Courthouse handles cases originating in Vacaville, Dixon, and the eastern county. The three courthouses operate with different conventions reflecting their respective populations.

Solano County's DUI calendar moves at moderate pace. Arraignments typically occur within 30 to 45 days. The Vallejo calendar has historically reflected the demographics of the western county; the Fairfield and Vacaville calendars reflect the more suburban-rural eastern county.

Cases originating in Fairfield, Suisun City, Travis AFB, Cordelia, Green Valley, and Rio Vista arraign at the Fairfield Hall of Justice. Cases from Vallejo and Benicia arraign at the Vallejo Hall of Justice. Cases from Vacaville, Dixon, and the eastern county arraign at the Vacaville Courthouse.

The DMV hearing for Solano 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.

Solano County APS hearings are typically handled by the Sacramento Driver Safety Office, though Oakland may handle some western county cases depending on routing. As of late 2024, most hearings are conducted virtually via Microsoft Teams. 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.

How DUI cases are handled in Solano County

The Solano County District Attorney's Office handles DUI prosecutions through dedicated deputies at each courthouse. The office has historically taken a moderate position on DUI cases, with somewhat firmer treatment of refusal allegations than some neighboring counties.

Standard first-offense dispositions in Solano County run three years of summary probation, the appropriate DUI program, fines and assessments commonly totaling $2,000 to $3,500, and court-ordered license suspension. Wet reckless reductions under §23103.5 are obtainable in cases with constitutional weaknesses or chemical test problems.

Felony DUI prosecutions, particularly DUI causing injury, are handled with significant attention.

Travis Air Force Base generates a significant share of cases involving military service members. The DA's office coordinates with the base on these cases but the criminal prosecution proceeds independently. Military command action under the UCMJ occurs parallel to and may precede the civilian case.

The I-80 corridor between the Bay Area and Sacramento generates a particular pattern of weekend evening cases involving drivers from outside the county. Cases from out-of-county defendants often resolve through negotiated dispositions with counsel handling the case through §977 appearances.

Cities and communities in Solano County

Solano County extends from the Carquinez Strait east through Suisun Marsh and the Vacaville-Dixon agricultural plain. The county includes seven incorporated cities and unincorporated areas under the Solano County Sheriff's Office.

Travis AFB is a federal military installation; civilian agencies have limited authority on base. Off-base arrests of Travis personnel are handled by Solano County agencies. The California Highway Patrol handles freeway arrests on I-80, I-680, Highway 12, Highway 37, and Highway 113.

DUI scenarios specific to Solano County

Solano County DUI arrests pattern around the I-80 corridor and the military and casino traffic in the area.

The I-80 corridor between the Bay Area and Sacramento generates the largest share of Solano County DUI cases. Weekend evening enforcement is intensive, particularly in the stretch through Fairfield and Vacaville. Cases often involve Bay Area or Sacramento residents arrested mid-route, with counsel handling the case through §977 appearances to minimize travel.

Travis Air Force Base service members face parallel UCMJ proceedings on DUI arrests. Loss of base access, security clearance, and command action under Article 15 are common consequences. The Travis Area Defense Counsel can provide military counsel; civilian-military attorney coordination is critical.

Vallejo waterfront and casino traffic generates some weekend DUI volume, particularly involving drivers heading to or from the casino developments and the Mare Island area.

Vacaville outlet mall traffic generates daytime DUI cases on holiday shopping weekends, though these are less common than evening cases.

The Suisun Marsh and Delta areas generate boating-while-intoxicated cases in summer months under Harbors and Navigation Code §655. The waterway access points generate substantial summer recreational DUI volume.

Highway 12 and Highway 37 corridors connect Solano County to Napa Valley wine country. Weekend wine country traffic generates DUI cases on these corridors, often involving out-of-county defendants.

Defenses that often apply in Solano County cases

Defenses commonly viable in Solano County DUI cases:

Stop challenges on the I-80 corridor are productive where the stop basis is thin.

Title 17 challenges apply to breath testing instruments used by Solano County agencies.

Rising BAC arguments work in cases with significant delay between driving and chemical testing, common in Solano County's longer transports from rural arrest locations.

Military-specific defenses can apply in Travis AFB service member cases where the timing of military and civilian proceedings creates evidentiary considerations.

Sobriety checkpoint challenges apply where checkpoints did not comply with Ingersoll requirements.

The first 72 hours after a Solano County DUI arrest

The first three days after a Solano County DUI arrest are decisive.

1. Locate the pink temporary license from booking. The ten-day APS clock runs from arrest.
2. Travis AFB personnel: contact the Travis Area Defense Counsel or civilian-military counsel immediately.
3. Identify the courthouse, Fairfield, Vallejo, or Vacaville, from your citation.
4. Preserve evidence. Receipts, text messages, dash cam footage.
5. Do not discuss the case with anyone other than counsel.
6. Request the APS hearing through (833) 543-7703.
7. Identify your arraignment date. Counsel can appear without you in most cases.
