Penalties for Refusing a Breathalyzer Test in California

Introduction to Breathalyzer Test Refusal in California

In California, refusing to submit to a breathalyzer test during a DUI stop can lead to severe penalties. This is due to the state's implied consent laws, which mandate that drivers agree to chemical testing as a condition of operating a vehicle. Understanding the consequences and legal framework surrounding breathalyzer test refusal is crucial for all drivers.

What is Implied Consent?

Implied consent laws stipulate that by obtaining a driver’s license, a driver has implicitly agreed to submit to chemical tests to determine blood alcohol content (BAC) if lawfully arrested for a DUI. In California, this includes breath, blood, or urine tests.

Legal Basis for Implied Consent

California Vehicle Code Section 23612 outlines the implied consent law, requiring drivers to undergo chemical testing if suspected of DUI. Refusing these tests can result in administrative and criminal penalties, regardless of whether the driver is ultimately convicted of DUI.

The Process of Breathalyzer Tests

1. Preliminary Alcohol Screening (PAS):

    - Conducted during a traffic stop using a portable device.

    - Used to establish probable cause for DUI arrest.

    - Refusal to take a PAS test has different implications for drivers under 21 and those on DUI probation.

2. Post-Arrest Chemical Tests:

    - Conducted after a DUI arrest.

    - More accurate than PAS tests and legally mandated under implied consent laws.

Penalties for Refusing a Breathalyzer Test

1. Administrative Penalties:

    - First Offense: Automatic one-year suspension of the driver’s license.

    - Second Offense (within ten years): Two-year license suspension.

    - Third or Subsequent Offense (within ten years): Three-year license suspension.

2. Criminal Penalties:

    - Refusal can be used as evidence in court, potentially resulting in harsher DUI penalties.

    - Possible jail time and fines, especially if combined with a DUI conviction.

Implications of Refusing a Breathalyzer Test

1. License Suspension:

    - Immediate administrative license suspension imposed by the DMV.

    - Drivers may request a DMV hearing to contest the suspension within ten days of the arrest.

2. Increased Legal Consequences:

    - Courts may impose stricter penalties for refusal, viewing it as an attempt to obstruct justice.

    - Refusal can lead to longer mandatory DUI education programs and probation periods.

Defending Against Breathalyzer Test Refusal Charges

1. Challenging the Legality of the Stop:

    - Arguing that the traffic stop was unlawful or that there was no probable cause for the DUI arrest.

2. Questioning the Refusal:

    - Demonstrating that the refusal was not willful, such as due to misunderstanding or medical incapacity.

3. Procedural Errors:

    - Highlighting any procedural mistakes made by law enforcement during the arrest or the request for the breathalyzer test.

What to Do If You Refuse a Breathalyzer Test

1. Request a DMV Hearing:

    - Immediately request a DMV hearing to contest the administrative license suspension. This must be done within ten days of the arrest.

2. Consult with an Attorney:

    - Seek legal counsel specializing in DUI cases to navigate the complexities of the legal system and build a robust defense.

3. Prepare for Court:

    - Gather evidence, such as witness statements or medical records, that may support your case.


Refusing a breathalyzer test in California can result in severe administrative and criminal penalties. Understanding the state's implied consent laws and the potential consequences of refusal is essential for all drivers. If you find yourself in this situation, it is crucial to act swiftly by requesting a DMV hearing and consulting with an experienced attorney to protect your rights and mitigate the penalties.

Final Thoughts

Navigating the aftermath of refusing a breathalyzer test requires a clear understanding of California's DUI laws and the implications of implied consent. By staying informed and seeking appropriate legal guidance, drivers can better manage the legal challenges and work towards a favorable outcome. For those facing DUI charges, awareness and proactive measures are key to maintaining driving privileges and minimizing legal repercussions.
