Hit by a Driver Who Fell Asleep at the Wheel? Here's What Michigan Law Says

A drunk driver leaves clues. There's a smell, a breath test, a blood alcohol number. A drowsy driver leaves almost nothing. There's no test for being too tired to drive.

That's what makes these cases tough. It's also why they matter so much. Drowsy driving can be just as dangerous as drunk driving. Research from the AAA Foundation for Traffic Safety found that drivers who get only 4 to 5 hours of sleep are about four times more likely to crash than drivers who got a full 7 hours. Less than 4 hours makes it even worse.

If a tired driver crashed into you, you shouldn't have to fight the insurance companies on your own. How is fatigue proven? What does your own insurance have to pay? When can you go after the driver for pain and suffering? This guide answers each of those questions.

For more than 50 years, the Lee Steinberg Law Firm has represented injured people across Michigan. With our Lee Free Guarantee, you pay no attorney fee unless we win.

The Short Version

• Drowsy drivers are dangerous drivers. Fatigue slows reactions and can cause "microsleeps," a few seconds of sleep the driver can't control.
• You can prove fatigue without a confession. Crash patterns, work schedules, phone records, and truck logs all tell the story.
• Truck drivers have strict hour limits. Breaking federal rest rules can prove both the driver and the trucking company were careless.
• Your own insurance pays medical bills and lost wages first. This is called PIP, and it pays no matter who caused the crash.
• Pain and suffering takes a serious injury. You'll generally need to meet Michigan's legal "threshold" to sue the tired driver.
• Deadlines start fast. Some insurance claims have one-year limits. Most injury lawsuits have three years.

Why Drowsy Driving Is So Dangerous

Being exhausted affects your brain a lot like alcohol does. It slows your reaction time, clouds your judgment, and makes it hard to pay attention.

The biggest danger is the microsleep. That's when your brain shuts off for a few seconds without warning. At highway speed, a car can travel the length of a football field in about four seconds. If the driver's eyes are closed for that long, nobody is steering.

That's why drowsy driving crashes are often so violent. The driver doesn't brake or swerve. The result is usually a high-speed rear-end crash, a car drifting out of its lane, or a head-on collision.

When and Where These Crashes Happen

Drowsy driving crashes tend to happen when your body naturally wants to sleep. That's usually between midnight and 6 a.m., and again in the late afternoon. Long, boring stretches of highway make it worse.

Some drivers are at higher risk than others:

• Truck and bus drivers working long shifts or chasing tight delivery deadlines
• Shift workers, like nurses and factory workers, driving home after overnight shifts
• Road trippers trying to "push through" instead of pulling over
• People on medications that cause drowsiness, especially mixed with little sleep or alcohol

Federal safety regulators have long identified driver fatigue as a major factor in serious truck crashes. For one example, read about this drowsy driving crash on I-94.

How Do You Prove a Driver Fell Asleep at the Wheel?

Since there's no breath test for being tired, these cases are built on circumstantial evidence: clues that, put together, point to one clear answer. Here's what we look for.

1. Clues at the Crash Scene

• No skid marks or swerving. An alert driver usually hits the brakes or tries to steer away. A sleeping driver doesn't.
• Drift patterns. Where the cars hit, and the damage, can show a slow drift across lanes or into oncoming traffic.
• Time and place. An early-morning highway crash right after an overnight shift is a big red flag.

2. The Driver's Work, Sleep, and Medication History

We dig into how long the driver had been awake and why. That can include:

• Work schedules and shift records
• Timecards, receipts, and witness statements that show how long they'd been up
• Prescription or over-the-counter medications with drowsiness warnings
• Anything they said at the scene, like "I was exhausted" or "I must have dozed off"

3. Black Boxes, Truck Logs, and Phone Records

Modern cars and trucks record a surprising amount of information. We work with experts to get and explain:

• Black box data. Most vehicles have an event data recorder that tracks speed, braking, and steering in the seconds before a crash. See how black boxes are used in injury cases.
• Electronic logging devices (ELDs). Most long-haul truckers must use these. They automatically record driving time and rest breaks.
• GPS, dashcam, and tracking data. These can show lane drifting, sudden jerks of the wheel, or long stretches of nonstop driving.
• Cell phone records. These can show the driver was up all night, or on their phone right before the crash.

Truck logs are especially powerful. They can show a company pushed a driver way past safe limits.

4. Witnesses and Experts

We also rely on:

• Eyewitnesses who saw the vehicle drifting, weaving, or not reacting to traffic
• Police reports noting fatigue or a driver who seemed out of it
• Crash reconstruction experts who can map out exactly how the crash happened
• Sleep and "human factors" experts who explain how exhaustion affects a driver's ability to react

Why You Need to Move Fast

Trucking companies and insurers often repair vehicles and wipe data quickly. So we send preservation letters right away. These are formal demands that they save the evidence. If they destroy it anyway, that's called spoliation, and courts can punish it. Acting fast can be the difference between a strong case and one with missing proof.

Drowsy Truck Drivers and Hours-of-Service Violations

When a tired truck driver causes a crash, federal rules give you extra ways to prove carelessness.

The Federal Motor Carrier Safety Administration (FMCSA) sets hours-of-service rules. These are limits on how long truckers can drive before they must rest. For most cargo truck drivers, the rules say:

• No more than 11 hours of driving after 10 hours off duty
• No driving past 14 hours after starting work, even if some of that time wasn't driving
• A 30-minute break after 8 total hours of driving
• No driving after 60 or 70 hours on duty in 7 or 8 days, depending on the company's schedule

When a driver breaks these rules, it's strong evidence they were dangerously tired. And it often shows the trucking company looked the other way.

Our Michigan semi-truck accident lawyers regularly go after:

• ELD and logbook records
• Dispatch and delivery schedules
• GPS and tracking reports
• Fuel and toll receipts, which can prove where a truck really was and when
• Company policies that push drivers toward unrealistic deadlines

Even with electronic logs required, drivers still break the rules and logs still get faked. Those records often explain exactly why a crash happened. Learn more about suing a trucking company for negligence and how Michigan truck laws affect your claim.

Common Injuries in Drowsy Driving Crashes

Because these crashes often happen at full speed with no braking, the injuries tend to be serious:

• Traumatic brain injuries and concussions
• Spinal cord injuries, including paralysis
• Broken bones and crush injuries to the arms, legs, ribs, or pelvis
• Neck and back injuries, like herniated discs and chronic whiplash
• Internal bleeding and organ damage
• Deep cuts, burns, and permanent scarring
• Emotional trauma, including PTSD after a car crash

Car crashes are one of the leading causes of hospital-treated brain injuries in the U.S., according to the CDC. Survivors often deal with long-term physical, mental, and emotional challenges. We work closely with medical specialists to document the full impact of these life-changing injuries.

What Compensation Can You Get?

After a drowsy driving crash in Michigan, you usually have two separate claims:

1. A No-Fault PIP claim with your own insurance, for medical bills, lost wages, and help around the house.
2. An injury claim against the tired driver (and in truck cases, the trucking company) for pain and suffering and other losses.

Your No-Fault PIP Benefits

Michigan is a "No-Fault" state. That means your own Personal Injury Protection (PIP) coverage pays first, no matter who caused the crash.

PIP generally covers your reasonable, necessary medical bills, a portion of your lost wages, and replacement services (help with chores you can't do), up to the limits you chose on your policy. Since the 2019 reforms, drivers can pick different medical coverage levels. Here's a full breakdown of what Michigan No-Fault insurance covers.

Our No-Fault lawyers help you:

• Figure out which insurance company has to pay under Michigan's priority rules
• File your Application for No-Fault Benefits correctly and on time
• Fight unfair PIP denials and delays
• Keep you from getting stuck with unpaid medical bills

One big warning: many PIP claims have one-year deadlines. There's also the one-year-back rule, which usually means that if you have to sue your insurer, you can only recover bills from the year before you filed. Waiting can quietly cost you money.

Can You Sue a Drowsy Driver for Pain and Suffering?

Yes, in many cases.

Because of No-Fault, Michigan only lets you sue for pain and suffering if your injury meets a legal threshold. That's a minimum level of seriousness. Under Michigan law, it means:

• Serious impairment of body function
• Permanent serious disfigurement
• Death

"Serious impairment of body function" means an injury doctors can see or measure, affecting an important part of your body, that changes your ability to live your normal life.

If you meet that bar, you can seek money for:

• Physical pain and emotional suffering
• Loss of enjoyment of life
• Anxiety, depression, and PTSD
• Loss of companionship

Separately, you may also be able to sue for "excess" costs, like medical bills or lost wages beyond what PIP covers. Those rules work differently and are worth discussing with a lawyer.

Your share of fault can also matter. Michigan reduces your recovery by your percentage of blame, and you lose pain and suffering if you're found more than 50% at fault. Here's more on Michigan's 51% rule and strategies to increase pain and suffering compensation.

Wrongful Death Claims

When a tired driver causes a fatal crash, Michigan's wrongful death law lets the estate's personal representative (the person in charge of the estate) seek compensation for:

• Lost financial support
• Loss of companionship, care, and guidance
• Medical bills and any pain and suffering before death
• Funeral and burial costs

Our wrongful death attorneys have secured seven-figure results in fatal and catastrophic auto cases, including $2,250,000 and $1,885,000 recoveries for crash victims and their families. Past results don't guarantee future outcomes, but they show our experience with serious cases. Learn who can sue for wrongful death in Michigan.

Michigan Deadlines You Can't Miss

One year for many PIP claims. Many lawsuits over unpaid PIP benefits must be filed within one year of the crash, with some exceptions. The one-year-back rule can also limit what you recover. These rules are technical and have changed in recent years, so talk to a lawyer early.

Three years for pain and suffering claims. Most Michigan injury lawsuits, including pain and suffering claims after a crash, must be filed within three years. Miss it, and you usually lose your right to sue. Here's more on how long you have to file a car accident claim in Michigan.

In drowsy driving cases, though, the deadline that often matters most is the evidence. Truck logs and black box data can be deleted or overwritten long before any legal deadline hits. Don't wait.

What to Do After a Suspected Drowsy Driving Crash

1. Call 911 and get medical care. Even if you feel fine, brain, neck, and back injuries may not show symptoms for hours or days.
2. Tell police what you saw. If the other driver was drifting or said they were tired or fell asleep, make sure the officer writes it down.
3. Take photos if it's safe. Get the vehicles, damage, skid marks (or the lack of them), the road, and any dashcams or company logos.
4. Get the driver's and company's info. For trucks or buses, write down the company name, truck number, and trailer number.
5. Collect witness names and numbers. Independent witnesses can be key to proving someone fell asleep. Here's what to do if you witness a car accident.
6. Talk to a lawyer before giving any recorded statement. Adjusters are trained to pay as little as possible. See how to handle talking to an insurance adjuster.
7. Call 1-800-LEE-FREE as soon as you can. We can lock down electronic data, send preservation letters, and protect your No-Fault and injury claims right away.

Michigan Drowsy Driving Accident FAQs

How can you prove a driver was asleep or fatigued?

It's rare to have direct proof that someone was literally asleep. Instead, we build the case from clues: crash patterns with no braking, the time of day, long driving hours in truck logs or GPS, work schedules and sleep history, statements from the driver or witnesses, and black box data showing no attempt to avoid the crash.

Can I sue a drowsy driver for pain and suffering in Michigan?

Yes, if your injury meets Michigan's threshold: serious impairment of body function, permanent serious disfigurement, or death. If it does, you can seek money for pain and suffering, emotional distress, and loss of enjoyment of life. Costs PIP doesn't cover may also be recoverable. We handle both your PIP claim and your injury lawsuit.

What if a truck driver broke hours-of-service rules?

Then both the driver and the trucking company may be responsible. Federal rules strictly limit how long truckers can drive before resting. We look at logs, dispatch schedules, and company safety practices, then go after everyone responsible. That can include the driver, the trucking company, and sometimes the broker or shipper. For a sense of what these cases can be worth, see our Michigan semi-truck accident settlement guide.

What does "no fee unless we win" actually mean?

It means you pay nothing upfront. We cover the costs of investigating and building your case. Our fee is a percentage of the settlement or verdict. If we don't recover money for you, you owe no attorney fee. No retainer, no hourly billing, and a level playing field against big insurance companies.
