Michigan’s Implied Consent law says that by driving on Michigan roads, you automatically give permission for a police officer to administer a chemical test if they have probable cause to believe you are operating under the influence. This applies to breath tests, blood tests, and sometimes urine tests.
But here’s the part most people don’t understand:
You can refuse — but the State will punish you for it.
What Happens If You Refuse the Chemical Test
A refusal triggers an automatic, mandatory penalty from the Michigan Secretary of State:
• 1‑year driver’s license suspension (no driving at all)
• 2‑year suspension if it’s your second refusal within 7 years
This suspension is separate from anything the court does on your OWI charge. Even if your OWI is dismissed, the Implied Consent suspension still stands unless you fight it.
You Have the Right to Appeal the Refusal
A refusal is appealable, and you have the right to challenge the officer’s claim that you refused. This is done through a Driver’s License Appeal Division (DLAD) hearing at the Secretary of State.
At this hearing:
• You can question the officer under oath.
• You can challenge whether the officer had probable cause.
• You can challenge whether you actually refused.
• You can challenge whether the officer followed proper procedure.
If the officer fails to appear, you win automatically.
If the officer does appear, the hearing becomes an opportunity to lock in their testimony — which can later help you in criminal court if your OWI case goes to trial.
If You Lose the SOS Hearing
Even if the Secretary of State upholds the refusal, you still have another option.
You can file an appeal in circuit court and ask the judge for a restricted license based on hardship. Judges have the power to grant restricted driving privileges for the entire one‑year suspension period if you can show:
• you need to drive for work
• you need to drive for medical reasons
• you need to drive for family responsibilities
• the suspension creates an undue hardship
This is often the only way to legally drive during an Implied Consent suspension.
Why Implied Consent Matters in Your OWI Case
A refusal can:
• increase your penalties
• affect plea negotiations
• impact your ability to drive
• give the prosecutor leverage
But it can also help your defense.
Refusal cases often involve:
• unclear instructions
• officer confusion
• improper warnings
• medical issues
• equipment problems
• miscommunication
These issues can be used to challenge both the refusal and the underlying OWI charge.
Bottom Line
Implied Consent is one of the most misunderstood parts of a Michigan OWI case. A refusal does not mean you’re guilty, and it does not mean you’re out of options. You have rights, you have defenses, and you have multiple opportunities to fight the suspension.
