What If the Driver Who Hit You Has No Insurance?

An uninsured driver doesn't mean you're out of options in Michigan. Here's what UM and UIM coverage do, what no-fault still pays, and the deadlines that catch people.

What If the Driver Who Hit You Has No Insurance?

They hit you, they were clearly at fault, and then they tell you they don't have insurance.

It's a sinking moment, and most people assume it means they're on their own. In Michigan, that's usually wrong — but what protects you is a coverage most drivers have never looked at, and a set of deadlines that don't care whether you knew about them. Here's how it actually works. For help after a crash, see our personal injury practice.

Your medical care doesn't depend on them

Start with the part that's already handled. Michigan is a no-fault state, so your own PIP coverage pays for reasonable and necessary accident-related medical care regardless of who caused the crash — and regardless of whether that person carried a policy.

The other driver being uninsured changes nothing about your medical benefits. We covered how PIP works in who pays your medical bills after a Michigan crash.

What their lack of insurance affects is everything beyond PIP: pain and suffering, and economic losses that exceed what no-fault covers.

That's where UM and UIM come in

Two optional coverages on your own auto policy do this work:

  • Uninsured Motorist (UM) — applies when the at-fault driver had no insurance at all. In many policies it also covers hit-and-run, where the driver is never identified.
  • Underinsured Motorist (UIM) — applies when they had insurance, but not enough to cover what you're actually owed. A minimum-limits policy against a serious injury runs out fast.

Functionally, you make a claim against your own insurer, which steps into the shoes of the driver who couldn't pay.

Here's the part worth checking tonight: UM and UIM are optional in Michigan. They're not automatic. Plenty of people discover they declined them at the moment they need them. Pull your declarations page and look — it takes two minutes, and the answer determines what happens if this ever occurs.

Why "they were at fault" still has to be proven

A UM claim isn't a formality. To recover, you generally still have to establish that the other driver was liable and that your injuries meet Michigan's threshold for noneconomic damages — death, serious impairment of body function, or permanent serious disfigurement.

And you're now negotiating with your own insurance company, which is a strange dynamic people aren't prepared for. Same adjusters, same scrutiny, same interest in paying less. Being their customer does not make it a friendly process.

The deadlines that quietly end claims

This is where uninsured-driver cases are lost.

  • UM and UIM are creatures of contract, not just statute. Your policy sets its own notice requirements and its own time limit to bring a claim — and those windows are often shorter than the general injury deadline. Some require notice within days.
  • Hit-and-run claims usually carry the strictest notice rules of all, frequently requiring a police report filed within a specific window of the crash.
  • No-fault benefits have their own separate clock, independent of any of the above.

Miss one and it doesn't matter how clear the other driver's fault was. Read the policy early, or have someone read it for you.

What to do if it happens

  • Call the police and get a report — essential in every case, non-negotiable in a hit-and-run.
  • Open your no-fault claim promptly so medical care isn't waiting on the fault question.
  • Tell your insurer there may be a UM/UIM claim rather than assuming they'll infer it.
  • Photograph everything at the scene — with no insurer on the other side, the evidence you gather matters more, not less.
  • Don't accept an early number just because it's your own company offering it.

When to call ELN

An uninsured driver turns one claim into two — the no-fault claim for your care, and a UM or UIM claim against your own carrier for everything else. They run on different rules and different deadlines, and the second one is adversarial no matter whose name is on the policy. If you've been hit by someone with no coverage, or by someone who drove off, get the policy reviewed before a notice window closes. ELN Law handles Michigan injury claims from the first call.
