According to the Massachusetts Department of Transportation, nearly 13,000 OUI-related arrests occur statewide every year. While many of these cases involve breath or chemical tests, a significant number of drivers are charged even after refusing to take a breathalyzer.
This raises a common question: Can you be charged with OUI in Massachusetts without taking a breath test? The short answer is yes. Understanding how and why that happens is critical for anyone facing drunk driving allegations in the Commonwealth.
This guide will explain how Massachusetts law handles OUI charges without chemical evidence, what refusing a breath test really means, and what rights and defenses you may have. Whether you’re researching for yourself or a loved one, this article provides a clear and easy-to-understand overview grounded in real laws and procedures.
In Massachusetts, OUI (Operating Under the Influence) means driving while impaired by alcohol, drugs, or both. A breath test isn’t required for a motorist to face OUI charges.
Under Massachusetts General Laws c. 90, § 24, prosecutors can pursue an OUI case based on other evidence of impairment, even without chemical test results. A BAC of 0.08% or higher helps, but it’s not essential for a conviction.
Yes. A breath test is just one piece of evidence in an OUI case. If you refuse the test, the arresting officer and prosecution team may rely on other types of proof.
These may include:
The absence of a chemical test does not prevent prosecutors from pursuing an OUI conviction if sufficient behavioral and observational evidence exists.
Massachusetts law allows charges to proceed even without a BAC reading. In fact, Commonwealth v. Zeininger (459 Mass. 775) confirmed that refusal to take a breath test cannot be used as evidence in a criminal OUI trial.
This protects your rights. However, it also means other forms of evidence must carry the case forward.
Massachusetts’ implied consent law means that by having a driver’s license, you agree to chemical testing if you’re arrested for OUI. Refusing the test triggers immediate license suspension—even if you’re acquitted.
According to the Massachusetts RMV: “If you refuse a breath test and it is your first offense, your license will be suspended for 180 days.”
This penalty comes from the RMV, not the court. It begins right after the refusal. While it may limit BAC evidence, the legal consequences start immediately.
Police rely on other evidence to support an OUI charge when no breath or blood test is available. This often includes field sobriety tests, such as the Horizontal Gaze Nystagmus, Walk-and-Turn, and One-Leg Stand. While common, these tests can be affected by anxiety, medical issues, or road conditions.
Officers may also use dashcam footage, 911 calls, your statements, witness accounts, and observed driving behavior. Even without a BAC reading, prosecutors often combine this evidence to argue impairment.
Refusing a breath test triggers automatic RMV penalties. The most immediate is a license suspension, and the length depends on your prior OUI history.

Refusing Breath Test |
Failing Breath Test |
License Suspension | 180 days (1st offense); longer for repeat offenders | 30 days + until court outcome |
Criminal OUI Charges | Still possible based on other evidence | Yes |
BAC Evidence in Trial | Not available | Admissible |
Prosecutor’s Burden | Must rely on officer testimony; field sobriety tests | Has chemical evidence (BAC) |
Can Refusal Be Used in Trial | No (in criminal case), but may be used in RMV hearing | N/A |
Strategic Note | Refusal may benefit you in court by limiting evidence | Provides direct BAC evidence to prosecutor |
However, that benefit comes with the trade-off of losing your driving privileges immediately, sometimes for months or even years.
Being charged with Operating Under the Influence (OUI) in Massachusetts is serious (even without a breath test). While chemical tests can provide strong evidence, prosecutors can still pursue charges using other forms of proof. However, the lack of a test opens the door to several possible defenses that challenge the handling of the case.
A skilled OUI defense attorney will examine all aspects of your arrest to find errors, weak spots in the evidence, or violations of your rights that could lead to reduced charges or a dismissal. Examples of potential defenses include:
Yes. Officers can arrest you based on signs of impairment, field sobriety test results, and their observations, even without a breath test.
Yes. Massachusetts imposes an automatic license suspension of at least 180 days for first-time offenders who refuse the test.
No. In Massachusetts, the fact that you refused a breath test cannot be mentioned in a criminal OUI trial. However, it can be used in RMV hearings.
Prosecutors can rely on field sobriety tests, the officer’s observations, witness testimony, and other circumstantial evidence to support the OUI charge.
Yes. You can request a hearing with the RMV, but these are administrative hearings, and the burden of proof differs from criminal court.
Refusing a breath test in Massachusetts may limit the evidence prosecutors can use in court, but it doesn’t stop them from charging you with OUI. The Commonwealth can move forward with your case using other evidence, such as field sobriety test results and police observations.
Understanding your legal rights, the penalties you face, and the strategies available for your defense is essential when navigating an OUI charge without a breath test.
