What is a DUI in California?

What is a DUI in California?

A DUI in California means driving under the influence of alcohol or drugs. In California, drivers over 21 must maintain a BAC below 0.08%, while commercial drivers have a 0.04% limit, and those under 21 are restricted to 0.01%. DUI drug charges also apply when any amount of illegal drugs or alcohol affect your driving ability. Police use Field Sobriety Tests and Chemical Test procedures to determine impairment.

A blood or breath test determines your blood alcohol level at the time of arrest. California Highway Patrol and local police departments arrest thousands of people for California DUI charges every year. The law applies to prescription medications that impair your ability to drive. Even legal substances can result in DUI charges if they affect your driving.

The Legal Process for DUI Charges in Orange County

The DUI Process begins when police stop your vehicle for suspected impaired driving. During a traffic stop, officers might request that you complete Standardized Field Sobriety Tests. You'll be arrested if police believe you're driving under the influence. Chemical testing happens at the police station or jail facility.

The arrest triggers two separate cases: criminal court and DMV license suspension proceedings. Your arraignment is the first court proceeding, during which you will plead guilty, not guilty, or no contest. Pretrial motions allow your DUI Trial Lawyer to challenge evidence and police procedures. Many cases are resolved through plea bargains before going to trial. A criminal trial becomes necessary when no plea agreement can be reached.

DUI Arrest and Breathalyzer Test

Police officers look for signs of impairment during traffic stops. Frequent signs often include the scent of alcohol, glassy or bloodshot eyes, and slurred words. Officers use portable breathalyzer devices during roadside investigations. You'll be arrested if the device shows alcohol in your system.

California's implied consent law requires chemical testing after arrest. Refusing a blood test or breath test results in automatic license suspension. The Intoximeter Alco-Sensor IV is commonly used for breath testing. Blood samples may be taken for gas chromatography analysis at crime labs.

Arraignment and Initial Court Appearance

The arraignment is your first court appearance after a DUI arrest. Formal charges will be issued, and you must enter a plea of guilty, not guilty, or no contest. Most people enter a not-guilty plea at arraignment. The judge may release you on your own recognizance or set bail. Court fees and other costs are explained during this hearing. You have the right to a Court-appointed attorney if you cannot afford private representation. Your DUI Defense lawyer can appear for you in most misdemeanor cases.

Pretrial Motions and Plea Bargains

Pretrial motions challenge evidence and police procedures in your DUI case. Common motions include suppressing illegally obtained evidence and challenging the results of tests. Your California DUI Defense Lawyer examines all aspects of your arrest for constitutional violations. Plea bargain negotiations may result in reduced charges for a lesser offense. Wet reckless or dry reckless charges carry lighter penalties than DUI convictions. Proposition 47 affects some drug crime charges related to DUI cases. Alternative sentencing options may include treatment programs instead of jail time.

DUI Trial Process

DUI trials involve jury selection, opening statements, and presentation of evidence. The prosecution presents their case first with officer testimony and test results. The DAwill also call an expert to testify about how alcohol intake affects driving. Your DUI Trial Lawyer cross-examines prosecution witnesses and challenges their testimony. The defense presents evidence that creates reasonable doubt about your guilt. Blood Testing Procedures and standardized field sobriety testing protocols often have flaws. Closing arguments summarize the evidence for the jury to consider and review. The jury deliberates before reaching a verdict of guilty or not guilty.

Common Defenses Against DUI Charges in Orange County

Common Defenses Against DUI Charges in Orange County

Successful DUI Defense requires challenging the prosecution's evidence and procedures. Police procedures must follow strict constitutional requirements during DUI investigations. Field Sobriety Tests have high error rates and are often administered incorrectly. Chemical testing equipment requires regular calibration and proper maintenance to ensure accurate results.

Medical conditions can affect test results and lead to false-positive readings. Rising blood alcohol concentration can show you were under the limit while driving. Illegal traffic stops violate your constitutional rights and can result in case dismissal. Experienced DUI Lawyers excel at uncovering flaws in the prosecution's case while ensuring your rights remain protected.

Inaccurate Breathalyzer or Blood Test Results

Regular calibration and maintenance are essential for breathalyzer machines to deliver precise readings. The Intoximeter Alco-Sensor IV can malfunction, resulting in false readings. Alcohol absorption rates vary among individuals based on body weight and metabolism.

Blood samples must be stored properly to prevent fermentation and false high readings. Gas chromatography testing can be compromised or performed improperly. Medical conditions like GERD can cause mouth alcohol and false positive results. Your DUI Lawyer examines all testing procedures for errors and constitutional violations.

Illegal Police Stop and Search Procedures

Law enforcement requires reasonable suspicion to pull you over for a DUI investigation. Traffic violations or erratic driving provide legal justification for traffic stops. Officers cannot stop vehicles based on anonymous tips without corroborating evidence. To remain constitutional, sobriety checkpoints must comply with strict legal criteria.

Illegal searches violate your Fourth Amendment rights against unreasonable searches. Evidence obtained through illegal stops must be suppressed at trial. Your DUI Defense attorney examines all police procedures for constitutional violations.

Medical Conditions and Rising BAC Defense

Breathalyzer results can be significantly impacted by medical issues, including diabetes. GERD causes stomach acid to create mouth alcohol that skews breath test readings. The rising BAC defense shows you were under the legal limit while driving. Alcohol absorption continues for 1-3 hours after your last drink.

Your blood alcohol concentration may have been legal while driving but illegal during testing. Time delays between driving and testing support the rising BAC defense. Medical expert testimony helps explain how conditions affect test results.

Penalties for DUI Convictions in Orange County

DUI convictions carry serious criminal penalties and administrative consequences in California. First-time offenders face up to six months in county jail. Fines start at $390 and can reach $1,000, along with applicable court costs and fees.

Fines total approximately $2,000, including court costs and fees. License suspension lasts four months for first-time offenders. Three-month DUI education programs are required for license reinstatement. Informal probation typically lasts three to five years. Community service may be required instead of some jail time.

Aggravating Factors for DUI Offenses

Aggravating factors increase DUI penalties significantly in California courts. A BAC registered 0.15% or higher triggers enhanced penalties. Traffic collision cases result in additional charges and longer sentences. Injury accidents can lead to felony DUI charges with prison time. Driving with passengers under 14 years old increases penalties. Prior DUI convictions within 10 years result in enhanced sentences. Refusing chemical testing adds additional license suspension time.

Insurance companies require SR-22 filings for reinstatement of a driver's license. Full license reinstatement requires completing all court requirements. DUI education programs must be finished before reinstatement. Fines and fees must be paid in full. Some convictions require the installation of ignition interlock devices for full reinstatement.
