The rear-end presumption
Michigan has a statute just for these crashes. Under MCL 257.402(a), when a vehicle overtakes and strikes the rear of another vehicle going the same direction, or one lawfully stopped on a highway, the rear driver is presumed negligent. You don’t have to prove why the other driver didn’t stop in time; they have to explain it.
Two driving rules usually sit behind the presumption. A driver may not follow more closely than is reasonable and prudent, considering speed, traffic and the road (MCL 257.643(1)). And a driver must be able to stop within the assured, clear distance ahead (MCL 257.627(1)).
When the presumption doesn’t hold
The rear driver can rebut the presumption with an adequate excuse. The common one is a sudden emergency the driver didn’t create, such as a car that cut in and braked without warning. Courts require clear, positive and credible evidence for that: in Nikprelaj v McConnaughey (Court of Appeals, September 19, 2025, unpublished), the court reversed a win for the rear driver because his affidavit and a repair invoice weren’t enough to show a sudden emergency.
The front driver can also share fault, for example by stopping suddenly for no reason, reversing, or driving with no working brake lights. Under comparative fault, each driver’s share reduces what they recover from the other.
Common injuries
The sudden forward-and-back motion of a rear impact causes neck and back injuries, including whiplash and soft tissue injuries, disc herniations and back and neck pain that can show up hours or days later. Concussions can happen without hitting your head. See brain injury claims. Get checked promptly and tell the doctor about every symptom, because insurers point to gaps in treatment to argue an injury wasn’t from the crash.
Your claims after being rear-ended
- No-fault benefits from your own insurer: medical care, lost wages and household help, regardless of fault. See no-fault benefits.
- Pain and suffering from the rear driver, if your injury meets Michigan’s serious impairment threshold, plus medical costs and wage loss above what no-fault pays.
- Car damage: your collision coverage, plus up to $3,000 from the rear driver through a mini-tort claim.
Chain-reaction crashes
When one car pushes another into a third, each impact is looked at separately. The driver who started the chain usually bears most of the fault, but a middle driver who was following too closely can share it. Collect the information of every driver involved, since you may have claims against more than one.
Photograph all the cars and their positions, get the crash report number and the rear driver’s insurance, and get medical care. Don’t give the other driver’s insurer a recorded statement before talking to a lawyer. The review is free, and there is no fee unless money is recovered.

Questions people ask us
Who is at fault in a rear-end collision in Michigan?
Usually the driver who hit the car in front. Under MCL 257.402(a), a driver who overtakes and strikes the rear of a car going the same way, or one lawfully stopped, is presumed negligent. The presumption can be rebutted, for example by a sudden emergency the rear driver didn’t create, and the front driver can share fault in some cases.
I was rear-ended. Who pays my medical bills?
Your own auto insurer, or a household relative’s, pays your no-fault benefits regardless of fault. The rear driver’s fault matters for your claim against them for pain and suffering and for the damage to your car.
Can I get money for whiplash after being rear-ended?
No-fault pays the treatment. Pain and suffering from the other driver requires an injury that meets Michigan’s serious impairment threshold, which soft-tissue injuries can meet when they are documented and affect your ability to lead your normal life.
What if I was rear-ended and pushed into the car in front?
In a chain-reaction crash, the driver who started the chain is usually most at fault, but each driver’s conduct is weighed. You may have claims against more than one driver, and your no-fault benefits are paid either way.
