If a police officer stops you for suspected drunk driving in Massachusetts, one of the first questions you may face is whether to take a breath test. It’s a split-second decision that can have lasting effects on your license and your case.
Many drivers believe refusing the test will help them avoid trouble, but under Massachusetts law, the consequences can be far more complicated.
This guide breaks down exactly what happens when you refuse a breath test, how the state’s implied consent law works, and what your options are if your license is suspended. Understanding these rules can help you protect your driving privileges and handle an OUI stop more confidently.
Massachusetts General Laws Chapter 90, Section 24(1)(f)(1) says that every licensed driver automatically consents to a chemical test of their breath, blood, or urine if arrested for operating under the influence (OUI). Refusing a test violates that consent.
By holding a Massachusetts driver’s license, you agree to cooperate with testing when lawfully arrested for OUI. This rule helps law enforcement determine blood alcohol concentration (BAC) levels and enforce public safety laws.
Massachusetts law states that any person operating a vehicle within the Commonwealth is deemed to have consented to a chemical test if lawfully arrested for OUI.
If you refuse the test, the officer must take your license and issue a suspension notice on behalf of the Registry of Motor Vehicles (RMV). The suspension begins immediately, even before any court date.
Refusing a breath test sets off two separate processes: a criminal case and an administrative license suspension. The RMV imposes penalties regardless of the court outcome.
For a first-offense refusal, the RMV suspends your license for 180 days. A second offense results in a three-year suspension, a third offense carries a five-year suspension, and a fourth or subsequent refusal can lead to a lifetime loss of driving privileges.
Refusing a breath test in Massachusetts causes an immediate RMV suspension, even if your criminal case is later dismissed or you’re found not guilty.
The RMV treats this as an administrative penalty separate from any criminal OUI prosecution. This means even if the case never reaches court, the suspension still applies.
Yes. Many drivers are surprised to learn they can lose their license without ever being convicted of OUI. The RMV’s authority to suspend a license for refusing a test is entirely separate from criminal court outcomes.
The administrative suspension applies even if you’re later acquitted. The RMV does not automatically reinstate a license after a not guilty verdict. The only way to challenge the suspension is through a timely appeal.
RMV suspensions are independent of court results. An acquittal does not guarantee your license will be restored.

You can appeal a breath test refusal suspension, but deadlines are strict. The appeal must be filed with the RMV within 15 days of receiving the notice. Missing that window usually means you cannot challenge the suspension.
During an appeal, you may argue that the officer lacked probable cause or that you were not lawfully arrested. If the appeal is denied, your license remains suspended for the full term.
A hardship license may be available later, depending on your record and cooperation with treatment programs. These licenses are limited and often require proof of financial hardship, as well as the installation of an ignition interlock device.
Many drivers assume refusing a test is always safer than failing one, but the consequences vary. A refusal can weaken the prosecution’s evidence, yet it results in longer RMV penalties. A failed test provides evidence for the case but typically leads to shorter suspensions.
|
Scenario |
Outcome | RMV License Suspension |
Impact on Criminal Case |
| Refuse Breath Test | No chemical evidence provided | 180 days (1st), 3 years (2nd), 5 years (3rd), lifetime (4th) | May weaken prosecution but prolongs license loss |
| Fail Breath Test (BAC ≥ 0.08%) | Evidence used in prosecution | 30-day suspension (first offense) | Strengthens prosecution’s case |
Refusal penalties also increase for commercial drivers or drivers under 21, making the decision even more significant. Learn more from the Massachusetts RMV OUI Information Page.
Understanding your rights is crucial when facing an OUI stop. You have the right to refuse a breath test; however, doing so results in the automatic suspension of your license by the RMV.
You are not entitled to consult an attorney before making a decision, and officers are not required to delay testing. OUI penalties and RMV actions are entirely separate. Choosing whether to refuse should depend on individual circumstances, prior OUI history, and potential defenses. Every case has different factors, which is why informed decisions matter most.

Refusing a breath test in Massachusetts has serious consequences, including immediate license suspension and limited appeal opportunities. While refusal may reduce evidence against you, it can extend how long you’re unable to drive.
