Breath & Blood Tests

Honolulu Breath & Blood Test Refusal Defense Lawyer

Experienced DUI Defense in Honolulu, Hawaii

Hawaii is one of the many states that now have an implied consent law governing procedure during a DUI arrest. Implied consent means that any driver pulled over on suspicion of a DUI must take a mandatory breath or alcohol test to provide their blood alcohol content (BAC).

Unfortunately, many drivers aren't aware of this law and may try to refuse to take a test. Even though officers are required to inform a driver that there are penalties for this refusal, they may not realize the extent of the consequences and how this could impact their charges. 

Over the last 25+ years, I have helped countless clients navigate their DUI charges away from further penalties due to implied consent violations and can use this experience to help with your case.

What Happens After a Breath or Blood Test Refusal in Honolulu?

Refusing a chemical test can trigger two separate tracks at once: a criminal DUI case and an administrative license action. Many people are surprised to learn that the license consequences can move quickly—even before your first court date—so the steps you take immediately after an arrest can make a major difference.

Common issues that come up after an alleged refusal include:

  • Immediate paperwork and deadlines: You may receive notices that require action within a short window to protect your driving privileges.
  • License revocation proceedings: Separate from the criminal case, an administrative process may determine whether—and for how long—your license is revoked.
  • Disputes about what counts as a “refusal”: Miscommunication, confusion, language barriers, medical issues, or unclear instructions can lead to an unfair refusal allegation.
  • Body cam and station procedures: Whether officers properly explained the consequences, followed required procedures, and documented events accurately can be critical.

At The Law Office of Kevin O'Grady, LLC, we focus on building a defense that addresses both fronts—seeking to reduce or avoid license penalties while also challenging the prosecution’s evidence. If you were arrested in Honolulu and accused of refusing a breath or blood test, contacting a lawyer promptly can help preserve time-sensitive opportunities to fight the case.

Common DUI Questions

  • What is considered to be a DUI in Hawaii?
    Like most other states, drivers found to be operating a vehicle with a blood alcohol content (BAC) level of .08% or higher will be arrested for DUI. In order to measure a driver's BAC, officers often subject drivers to breath tests, blood tests, or urine tests. In other instances, a police officer may ask a driver to participate in a field sobriety test. In Hawaii you can be charged with per se (BAC) and or with impairment (regardless of your BAC).
  • I was arrested for a DUI. When should I talk to a lawyer?
    Immediately. In the state of Hawaii, a police officer will issue an instantaneous driver's license revocation upon a DUI arrest. Your attorney can take steps to request and or preserve evidence early after your arrest and can also speak with witnesses or visit the scene close in time to your arrest. Your attorney will be able to represent you during this administrative hearing, as well as any type of criminal proceeding thereafter.
  • What will happen to my driver's license if I do not petition a license revocation?
    If you fail to take action and request a hearing in a timely manner, you could be jeopardizing your driving privileges. Upon arrest, an arresting officer will issue you a Notice of Administrative Revocation. This notice will serve as a temporary driving permit for 30 days. An in-person administrative hearing must take place within 24 days of receiving a Notice of Revocation. Failure to take action on a first-time DUI offense could result in a mandatory driver's license revocation for up to 1 year.
  • Is it required by law to take a breath or chemical test?
    You do have the right to refuse a breath or chemical test, however, you will also face possible penalties as a result of refusing a chemical test. Admittedly, chemical tests are prone to error and inaccuracy, however, it will be imperative that you listen to law enforcement officers. Refusal of a breath or chemical test could result in a license revocation for up to 2 years on a first-time offense.
  • What happens if I failed a field sobriety test?
    Do not assume that your case will rely solely on the results yielded during a field sobriety test! Even if you have failed a field sobriety test, these tests are not always accurate and often do not take in special circumstances of the person taking the test.

    For example, people with health issues, coordination issues, or sight issues may not perform in a way that would suggest sobriety. Additionally, other external factors, such as uneven roads, weather, stress, or improper administration by the police officer could lead to erroneous results.
