Spring Forward, Crash More: Daylight Saving Time and Drowsy Driving

We lose one hour of sleep when the clocks jump forward — and Michigan roads pay for it. Research consistently shows a measurable spike in car crashes in the days after the spring time change, driven by millions of tired, out-of-rhythm drivers. Here's why it happens and what your rights are if a drowsy driver hurt you.

We're Big League Injury Lawyers, and every March we brace for the “spring forward” bump. When Michigan sets clocks ahead the second Sunday of March, most of us shrug off the lost hour. But sleep scientists have documented that the transition disrupts the body's internal clock for days, and multiple studies have linked the Monday and Tuesday after the change to a rise in fatal and injury crashes. Fewer daylight hours in the morning commute add to the problem.

Why the Time Change Makes Roads More Dangerous

Losing an hour doesn't sound like much, but sleep loss is cumulative and the effects are real. Drowsy driving impairs reaction time, attention, and judgment in ways that experts compare to alcohol impairment. Being awake for extended periods can produce deficits similar to driving over the legal alcohol limit. After the spring change, the risks stack up:

• Delayed reaction time — a fatigued driver takes longer to brake or steer away from danger
• Microsleeps — brief, involuntary lapses of a few seconds where a driver is effectively asleep at highway speed
• Impaired judgment — tired drivers misjudge gaps, speeds, and distances
• Darker morning commutes for the first weeks after the change, reducing visibility

A driver traveling 70 mph on I-696 or US-23 covers more than 100 feet every second. A three-second microsleep means the length of a football field passes with no one in control.

Drowsy Driving Is Negligence in Michigan

Here's what many people don't realize: getting behind the wheel dangerously fatigued is not an excuse — it's a form of negligence. A driver has a duty to operate a vehicle safely, and that includes not driving when they're too tired to do so responsibly. When a drowsy driver drifts across the center line, rear-ends stopped traffic, or runs off the road and hits you, they can be held liable just as if they had been texting or speeding.

The challenge is that fatigue leaves no breathalyzer reading. Unlike a drunk driver, a drowsy one doesn't blow a number. That's why proving fatigue takes a careful, evidence-driven investigation.

How We Prove a Driver Was Too Tired to Drive

Fatigue cases are built from circumstantial evidence that, taken together, paints a clear picture:

• The driver's own admissions — “I dozed off,” “I never saw them,” or statements to police at the scene
• The type of crash — single-vehicle run-off-road, rear-end into stopped traffic, or a drift across lanes with no braking are classic fatigue signatures
• No skid marks or evasive action — an alert driver reacts; a sleeping one doesn't
• Time of day — early morning and mid-afternoon crashes align with natural dips in alertness
• Work and activity records — a long shift, an overnight schedule, or hours-of-service logs for commercial drivers
• Phone and telematics data and event data recorder (“black box”) downloads showing throttle, braking, and steering — or the lack of it
• Witness statements describing erratic or drifting driving before impact

Your Claims Under Michigan Law

A drowsy-driving crash is handled like any other motor-vehicle collision in Michigan — which means two tracks of recovery.

1. No-Fault PIP Benefits

Michigan is a no-fault state, so your medical bills and a portion of your lost wages are covered by Personal Injury Protection (PIP) benefits regardless of who caused the crash. PIP flows through your own policy or the correct insurer under Michigan's priority rules. This is your first source of coverage after any crash, and it kicks in whether the other driver was asleep, distracted, or simply careless.

2. A Third-Party Claim Against the Drowsy Driver

For the losses PIP doesn't pay — especially pain and suffering — you can bring a third-party liability claim against the at-fault driver. Under MCL 500.3135, non-economic damages are available when the crash caused death, permanent serious disfigurement, or a serious impairment of body function. Because fatigue crashes often happen at speed with little braking, injuries are frequently severe enough to clear that threshold.

A Note on Comparative Fault

Michigan uses modified comparative negligence. If the defense argues you share some blame, your recovery can be reduced by your percentage of fault, and being found more than 50% at fault can bar non-economic damages. In a fatigue case, the defense may try to shift responsibility — another reason a documented, well-investigated claim matters.

What to Do After a Drowsy-Driving Crash

1. Call 911 and get medical care — a prompt, complete treatment record protects both your health and your PIP claim.
2. Tell the officer what you observed — if the other driver said they fell asleep or drifted, make sure it's in the report.
3. Write down the driver's statements as soon as you can, word for word if possible.
4. Photograph the scene — note the absence of skid marks, the angle of impact, and lane position.
5. Get witness contact information — independent observers of drifting or erratic driving are gold in fatigue cases.
6. Don't give a recorded statement to the other insurer before speaking to a lawyer.
7. Act promptly. Black-box data and telematics can be overwritten, and Michigan's three-year statute of limitations, while longer, is not a reason to delay preserving evidence.

Special Concern: Commercial and Shift Drivers

The dangers multiply with commercial trucks and gig drivers running long or overnight routes. Federal hours-of-service rules limit how long truckers can drive, and violations can be powerful evidence of negligence. Right after the time change, a fatigued trucker on I-75 or I-94 is a serious hazard. Those logs, dispatch records, and ELD (electronic logging device) data are exactly the kind of proof that gets preserved fastest when a lawyer is involved early.

Bottom Line

The lost hour is real, and so are its consequences on Michigan roads. Drowsy driving is a choice, and when that choice puts you in the hospital, the law treats it as negligence — not bad luck. Between no-fault PIP benefits and a third-party claim for your pain and suffering, you have real avenues to recovery. Because fatigue can't be measured with a roadside test, these cases live and die on evidence gathered early. If a tired driver hurt you this spring, let us start building the record before it fades.
