After an OVI arrest in Ohio, the officer will ask you to take a chemical test. You are allowed to say no, and many people assume that saying no protects them because the state never gets a number. Refusing does keep a BAC result out of the case. It also sets off an automatic license suspension, gives the prosecutor an argument to use at trial, and changes how the court treats the charge. This article covers what Ohio's implied consent law says, what a refusal triggers, and what a defense lawyer looks at once it has happened.
Can you refuse a breathalyzer in Ohio?
Yes, you can refuse, but Ohio attaches automatic consequences to the refusal under its implied consent law, ORC 4511.191. The idea behind implied consent is that by driving on Ohio roads, every driver has already agreed to a chemical test if lawfully arrested on suspicion of OVI. Refusing that test puts you in two systems at once: an administrative license suspension and the criminal OVI case.
A chemical test covers more than the breath machine. It means a breath, blood or urine test, and since HB 37 (Liv's Law) took effect on April 9, 2025, it also includes an oral fluid (saliva) swab. Refusing the swab brings the same implied consent penalties, including the automatic suspension.
What happens to your license if you refuse?
Your license is suspended right away. The officer takes your license on the spot and issues a paper Administrative License Suspension (ALS). For a first refusal the ALS lasts one year. A second refusal within ten years brings a two-year ALS. These suspensions run from the date of arrest, and they apply whether or not you are ever convicted of OVI.
A refusal also affects how soon you can drive again. In a non-refusal first OVI, a judge may waive the hard suspension that comes before limited driving privileges if you have no prior "Physical Control" conviction within 10 years. In a refusal case, the court cannot waive that hard suspension, even if you agree to install an ignition interlock. For most people this is the part of a refusal they feel first, because it decides how long they cannot get to work. The firm's page on limited driving privileges explains how the application works once you are eligible.
You can challenge the ALS. The ALS appeal must be filed within 30 days of the arrest, and the appeal can ask for a stay of the suspension while it is pending. Missing that window usually forfeits your right to contest the ALS. The firm's article on the 30-day ALS appeal deadline covers the timing in more detail.
Can a refusal be used against you in court?
Yes. Ohio courts allow prosecutors to comment on your refusal at trial, and a jury may draw an adverse inference from it: that you refused because you knew you were impaired. This is often called the "consciousness of guilt" argument.
The argument can be answered. People refuse for many reasons, including confusion, fear, distrust of the machine, or a poor explanation from the officer. A defense lawyer can put those explanations in front of the jury and cross-examine the officer on whether you were properly advised of the consequences of refusal under ORC 4511.191 before the test was requested. Whether the refusal evidence is admitted at all is part of the defense in a refusal case.
Can you still be convicted of OVI if you refuse the test?
Yes. ORC 4511.19(A)(1)(a) allows an OVI conviction on evidence that you were under the influence of alcohol, whatever a chemical test would have shown. Officers testify about slurred speech, bloodshot eyes, the odor of alcohol, erratic driving and poor performance on field sobriety tests. Prosecutors regularly win OVI convictions without chemical test evidence, and in refusal cases they often argue that the refusal plus the officer's observations is enough.
A refusal removes one kind of evidence and leaves the rest of the case in place.
Is a refusal treated as a high-level OVI?
Often, yes. Ohio sorts a first OVI into two levels. The low level covers a BAC at or above .08% but below .17%. The high level covers a BAC of .17% or higher, or refusing the chemical test. A refusal is often treated as high level, especially when there is a prior OVI within 20 years. That 20-year window is one of the limited situations where Ohio looks back further than the usual 10-year lookback for counting prior offenses.
The level matters because it sets the minimum jail term. Other parts of a first-offense sentence are the same at either level: fines of $565 to $1,075 and a court-ordered license suspension of 1 to 3 years. The firm's guide to high-tier OVI in Ohio covers what the high level changes.
Refusing field sobriety tests is a different decision
Declining the roadside field sobriety tests does not trigger an ALS. These are the walk-and-turn, the one-leg stand and the horizontal gaze nystagmus test, and Ohio attaches no statutory penalty to declining them. An officer may still use your refusal as one factor in deciding to arrest you, and it may be mentioned at trial.
The chemical test comes after the arrest and falls under implied consent. The field sobriety tests come before it and do not. People mix the two up at the roadside, and it is worth knowing which request you are answering. The firm's article on field sobriety tests in Ohio explains how those tests are challenged.
What a refusal trades away
No article can tell you what to do at a particular stop, because the answer depends on facts nobody knows in advance. What can be laid out is the trade.
On one side, the prosecution will not have a BAC number. That matters, because a test result is often the strongest single piece of evidence in an OVI case, and a result of .17% or higher makes the charge high tier.
On the other side, a refusal brings:
- a one-year ALS for a first refusal (two years for a second within ten years), starting at arrest;
- a hard suspension before limited privileges that the court cannot waive, even with an interlock;
- refusal evidence at trial and the consciousness of guilt argument;
- treatment as a high-level OVI in many cases.
A test result is also open to challenge. Breath results can be attacked for calibration, missing maintenance records, operator error, a rising BAC or a medical condition. Blood tests can be challenged for how the sample was collected, the chain of custody and lab error. A refusal removes those arguments along with the number.
What the firm looks at after a refusal
The firm reviews the whole sequence: the traffic stop, the officer's observations, the field sobriety test request, the chemical test request and every advisement given. The defenses that come up most in refusal cases are these:
- No reasonable grounds. The officer lacked reasonable grounds to stop or arrest you.
- Improper advisement. The officer did not properly explain the consequences of refusal before asking for the test.
- Not a valid refusal. The refusal itself was not knowing and voluntary.
- The refusal evidence. Other explanations for the refusal, and cross-examination on the advisement, can answer the consciousness of guilt argument.
The firm also files the ALS appeal, asks for a stay, applies for limited privileges when you become eligible, and negotiates for charge reductions or plea agreements that avoid the mandatory jail tied to a refusal conviction. The refusal OVI page sets out the penalties in full, and the main OVI/DUI defense page covers every offense level.
