What is implied consent in Michigan and what really happens if you refuse the breath blood or urine test after an OWI arrest?
Implied consent in Michigan means drivers must submit to a post‑arrest chemical test, and refusing it triggers a 1‑year license suspension, 6 points, and a short 14‑day deadline to request a hearing.
I have defended clients across West Michigan for decades, handling hundreds of drunk driving cases and license hearings. Grand Rapids DUI defense services or call (269) 808-8007 to talk with me now about your options.
In this article, I’ll cover what the law means, penalties, defenses, timelines, and the steps I take to protect your license.
What Is Implied Consent and Key Concepts
Implied consent ties your Michigan driving privilege to a duty to take a chemical test after a lawful OWI arrest. Police must read specific chemical test rights before requesting a breath, blood, or urine sample.
A chemical test is not the roadside handheld breath test. The roadside device is the Preliminary Breath Test used during the stop to help decide probable cause. The evidential test occurs at the station or a medical facility.
If you refuse the evidential test after arrest, the Secretary of State begins a separate license sanction. That civil process is different from the criminal OWI case and follows set rules and deadlines.
Why Implied Consent Matters for Michigan Drivers
Refusal penalties hit fast. A first refusal triggers a one year suspension and six points on your record. A second refusal within seven years can mean a two year suspension.
Winning the civil hearing keeps your driving privileges intact while we fight the criminal case. See my license restoration guide to understand how I rebuild privileges after sanctions.
How the Process Works Step by Step
Stay calm and provide identification only. Do not make admissions about drinking or medications.
Know the difference between the roadside PBT and the post‑arrest evidential test. Refusing the PBT is a civil infraction; refusing the evidential test triggers a suspension case.
Listen as the officer reads chemical test rights. Ask to re‑read if unclear or if English is not your first language.
If you refuse, expect an Officer’s Report of Refusal and a temporary paper license.
Call me right away. I submit the hearing request within 24 hours so you do not miss the 14‑day window.
Save documents. Keep bond papers, ticket, the refusal form, and any hospital papers together.
I prepare for the hearing by subpoenaing the officer if needed and challenging probable cause, proper advisement of rights, and whether you actually refused.
Attend the Secretary of State hearing. I present cross‑examination and exhibits to show the request was unlawful or confusing.
Review outcomes. If we win, the suspension is set aside. If we lose, we pursue restricted privileges where available and protect the criminal case.
Continue the criminal defense with a focus on video, calibration records, and medical evidence.
Options Drivers Consider After Arrest
- Submit to the evidential test and challenge the criminal case later.
- Refuse the test and fight the license case at the hearing.
- Consent to a blood draw if a breath machine is unavailable and preserve medical defenses.
Michigan Specifics That Affect Timing and Evidence
Statutes and code sections. Implied consent is governed by MCL 257.625c and hearing procedures under MCL 257.625f. The under‑21 standard appears in MCL 257.625(6).
Deadlines. The hearing request must be received by the Secretary of State within 14 days of arrest or the suspension starts automatically.
Common forms and reports. Officers complete an Officer’s Report of Refusal to Submit to Chemical Test and issue a temporary paper license. Hospital draws generate lab reports we can request.
Local practices. Kent and Kalamazoo County courts often schedule arraignments within days. I move quickly with preservation letters and video requests. See my Grand Rapids DUI overview for how I stage a defense while the civil case runs.
Common Pushbacks and How I Respond
Insurers may spike premiums after a refusal, citing risk and points. I help clients compare carriers and document clean periods to reduce increases. Prosecutors may treat refusals as aggravating. I counter with medical issues, confusion about rights, or clean histories.
For testing issues, I review training and calibration logs. When agencies cannot document compliance, I leverage that gap. Michigan State Police publish an overview of impaired driving rules that I use when educating clients; see the MSP impaired driving law page.
Documentation That Helps at Hearings
Bring proof of employment, treatment enrollment, medical records explaining refusals such as asthma or GERD, and any names of witnesses. I also pull patrol and body‑cam video and the station log to confirm that rights were read correctly.
Timeline and Common Delays
Hearings are usually set three to eight weeks after the request. Delays occur when officers are unavailable or when hospitals need time to release lab data. I track deadlines and push for timely disclosure so we can prepare early.
Decision Framework for Next Steps
If the stop looks weak or rights were garbled, we press the hearing and the criminal case. If the hearing looks risky but trial evidence is thin, we consider a negotiated reduction to impaired driving while pursuing restricted privileges. Every case is fact specific, and I explain tradeoffs in plain English.
How Refusal Penalties Compare With Taking the Test
This quick table contrasts refusing the evidential test with taking it and contesting the results later.
| Choice | Immediate Consequences | Long-Term Impact |
|---|---|---|
| Refuse the Evidential Test | 1-year license suspension (2 years if prior refusal), 6 points on record, 14-day hearing deadline. | Possible higher insurance rates, harder negotiations with prosecutors, but may suppress unreliable test results. |
| Take the Test and Contest Results | Evidence of BAC entered into the criminal case, but no automatic implied consent suspension. | Defense may focus on machine errors, medical issues, or procedural mistakes; potential to reduce or dismiss charges. |
| Consent to Blood Draw | More invasive but often accurate; handled at hospital or medical facility. | Lab reports can be independently reviewed; delays or errors in collection may provide strong defenses. |
