What to Do If a Car Accident Was Caused by Driver Fatigue

All Practice Areas

Each day, drivers across the country get behind the wheel while dangerously tired, often underestimating the risk they pose to themselves and others. A driver fatigue car accident is not just unfortunate—it can be deadly. Fatigued or drowsy driving is a leading cause of severe crashes, and when it happens, questions of liability, insurance claims, and legal consequences arise.

This article will help you understand what steps to take if you’ve been in a crash caused by a sleepy driver, how liability is determined, what kind of evidence can prove fatigue, and how to pursue compensation through insurance or legal action.

 

Why Driver Fatigue Is a Serious Safety Hazard

Fatigue dramatically impairs a driver’s ability to make sound decisions, respond quickly, and maintain focus. It’s often compared to drunk driving in terms of the cognitive impairment it causes. Fatigued drivers are more likely to drift between lanes, miss traffic signals, or fall asleep entirely—especially during long drives or late-night hours.

Common causes of fatigue-related driving accidents include:

1. Operating a vehicle during nighttime hours or long-haul travel without adequate rest.
2. Medical issues such as sleep apnea or insomnia that interfere with a person’s ability to get restorative sleep.
3. Use of medications that induce drowsiness, including antihistamines, opioids, or prescription sleep aids.
4. Occupational fatigue, especially among truck drivers, shift workers, and those working extended hours without proper breaks.

Fatigued driving is responsible for a significant number of crashes. The National Highway Traffic Safety Administration (NHTSA) estimates that drowsy driving contributes to over 90,000 crashes each year, resulting in thousands of injuries and deaths. However, because it’s difficult to prove, this number is believed to be significantly underreported.

 

Legal Consequences of Falling Asleep While Driving

Legally speaking, falling asleep at the wheel is not a minor lapse in judgment—it is often viewed as negligence. Drivers have a legal responsibility to ensure they are fit to drive before starting their vehicle. When they fail to meet this obligation, and an accident occurs, they can be held responsible for the consequences.

Courts may treat fatigue-related crashes as either simple negligence or gross negligence, depending on the circumstances. For example, if a commercial truck driver knowingly violated federal Hours of Service (HOS) regulations and caused an accident, a court might consider that reckless or even willful misconduct.

Negligence is the foundation of most personal injury lawsuits. If the other driver had a duty of care (which all drivers do), breached that duty by operating a vehicle while overly tired, and caused you harm as a result, then you may have a valid legal claim.

The law recognizes driver fatigue as a foreseeable and preventable risk. Therefore, drivers who ignore signs of tiredness can be held accountable just as they would be for driving drunk, texting while driving, or running a red light.

 

Who Is Liable in a Drowsy Driving Crash?

Liability in a fatigue-related accident depends on multiple factors. Most often, the fatigued driver is directly responsible, but in some cases, other parties may share the blame.

Here are examples of who might be held liable:

The Driver

If the driver ignored signs of exhaustion or chose to drive after an extended period without sleep, they can be found personally liable for the accident.

The Employer

In commercial driving cases, such as truck or delivery drivers, the company may be held responsible under a legal doctrine known as “respondeat superior” if the accident happened during the driver’s work duties. If the employer pressured the driver to exceed safe driving limits, their liability increases.

Third Parties

In rare cases, liability may extend to third parties, such as a doctor who prescribed sedatives without adequate warning, or a car manufacturer whose fatigue-detection technology failed (if equipped).

Understanding who is responsible is key to determining how to pursue your claim. Often, multiple parties are involved, which makes legal representation even more important.

 

Evidence Needed to Prove Fatigue in Car Accidents

Unlike drunk driving, there’s no breathalyzer for fatigue. That means proving that the at-fault driver was tired at the time of the crash can be challenging, but not impossible. Investigators rely on circumstantial evidence and behavioral indicators to demonstrate that fatigue likely played a role.

Common types of evidence used in fatigue-related cases include:

1. Police Reports

Officers often record observations at the scene. If the driver admitted to being tired or there were no skid marks (suggesting no attempt to brake), it may support a fatigue-related claim.

2. Eyewitness Testimonies

Passengers, bystanders, or other drivers may report seeing the driver nodding off or swerving prior to the collision.

3. Surveillance or Dashcam Footage

Video evidence can show erratic driving behavior consistent with drowsiness or unconsciousness behind the wheel.

4. Driver Logs and Work Schedules

For commercial drivers, logs can show whether the driver had sufficient rest. Fatigue is a common issue in the trucking industry due to tight deadlines and long routes.

5. Medical Records and Medication History

If the driver had a known sleep disorder or was on medication that induces drowsiness, it can further support the claim.

6. Black Box Data

Many vehicles now contain event data recorders that track speed, braking, and steering. A sudden lack of input can indicate that the driver was incapacitated.

The burden of proof is on the victim, but you only need to show that it is more likely than not that fatigue caused the accident—this is the legal standard known as a “preponderance of evidence.”

 

Filing Insurance Claims for Fatigue-Related Crashes

Fatigue is not always explicitly listed in crash reports, and insurance companies may try to downplay it as a cause. This makes it important to be proactive in how you file your claim.

When filing a claim, consider the following:

1. Provide a detailed statement to the insurer describing why you believe fatigue was a factor. Include anything you observed, such as the driver’s yawning, slow reaction, or inconsistent lane behavior.
2. Ask for a copy of the police report, especially if the officer noted signs of tiredness or lack of control by the other driver.
3. Keep records of your injuries, repairs, and out-of-pocket costs.
4. If your claim is denied or undervalued, consider hiring an attorney to negotiate or escalate the claim to litigation.

If the other party’s insurance denies responsibility, or if their coverage limits don’t meet your needs, you may have to pursue damages through your own underinsured/uninsured motorist policy or file a lawsuit.

 

When and How to Sue a Driver for Drowsy Driving

Lawsuits are typically the next step when insurance doesn’t provide fair compensation, or when your injuries are significant. Filing a lawsuit allows you to seek damages for both economic and non-economic losses.

Damages in a drowsy driving lawsuit may include:

• Medical expenses, including future treatment
• Lost wages or loss of earning capacity
• Pain and suffering
• Mental anguish
• Permanent disability or disfigurement
• Punitive damages (in cases of egregious conduct)

To file a lawsuit, you’ll typically begin by consulting a personal injury attorney. Your lawyer will assess the merits of your case, gather evidence, file the complaint, and represent you in settlement negotiations or court.

It’s critical to act within your state’s statute of limitations, which varies but is commonly two to three years from the date of the accident. Delaying could jeopardize your ability to collect damages.

 

What To Do If You’re Hit by a Sleepy Driver

If you suspect the driver who hit you was fatigued, taking the right steps immediately after the crash is vital. What you do in those first moments can make a huge difference later.

Follow these steps:

1. Call 911 and report the crash. Let the dispatcher know if anyone appears injured or unconscious.
2. If safe, take photos of the scene, damage, skid marks (or lack thereof), and the other driver’s condition.
3. Tell the police your observations—if the driver seemed tired, said they were exhausted, or looked like they had just woken up.
4. Seek medical attention right away. Even if you feel fine, symptoms like whiplash or concussion can show up later.
5. Contact a personal injury attorney as soon as possible. They can protect your rights, gather time-sensitive evidence, and deal with the insurance company.

You don’t have to prove everything yourself—but documenting what you can early on makes your claim much stronger.

 

Frequently Asked Questions

Can I sue if the other driver fell asleep at the wheel?
Yes, you can sue if the other driver fell asleep and caused a crash. Falling asleep while driving is typically considered negligence, especially if it results in injuries or property damage. If the fatigued driver’s behavior directly caused the accident, you may have the right to pursue compensation through a personal injury lawsuit. Your case will depend on proving that the driver’s fatigue led to careless or unsafe driving and that you suffered actual harm as a result.

How do I prove a driver was too tired to drive?
Proving that a driver was fatigued at the time of the accident can be challenging, but not impossible. While there is no breathalyzer-style test for fatigue, evidence can be gathered from a variety of sources. This includes police reports indicating signs of drowsiness, eyewitness accounts describing erratic driving, surveillance or dashcam footage, and data from the vehicle’s black box. In commercial driving cases, driver logs and work schedules may also show that the driver was overworked or had not taken adequate rest breaks.

Is driver fatigue considered a valid legal claim?
Yes, driver fatigue is a valid legal basis for a negligence claim. Courts recognize that driving while excessively tired poses a serious danger to others on the road and may treat it similarly to driving under the influence. If fatigue contributed to the accident and you can establish that the driver failed to exercise reasonable care, your claim has legal merit. Fatigue-based claims are especially strong when backed by corroborating evidence and medical documentation.

What damages can I recover in a fatigue-related accident lawsuit?
In a fatigue-related accident lawsuit, you may be entitled to a variety of damages. These typically include medical expenses, both current and future, as well as lost wages if your injuries prevented you from working. You can also seek compensation for pain and suffering, emotional distress, and diminished quality of life. In some cases, where the conduct was especially reckless—such as a commercial driver ignoring required rest periods—punitive damages may also be awarded to punish the wrongdoer and deter similar behavior in the future.

What should I do if I think the other driver was drowsy but they deny it?
If you suspect the other driver was drowsy but they deny it, focus on collecting and preserving as much evidence as possible. Tell responding officers about any signs you noticed, such as the driver appearing dazed, confused, or having slow reactions. Ask if any nearby cameras may have recorded the incident. Consider hiring a personal injury attorney who can help launch an investigation, request driver logs or cellphone records, and consult accident reconstruction experts. Even if the driver denies fatigue, a thorough investigation may still uncover supporting facts that validate your suspicion.

 

Final Thoughts: Don’t Let a Fatigued Driver Walk Away Without Consequences

Fatigue-related car accidents are entirely preventable, yet they continue to claim lives and destroy families. If you’ve been injured because another driver chose to drive while tired, you deserve compensation and accountability. Navigating the legal system can be complex, especially with insurance companies reluctant to acknowledge fatigue as a legitimate factor. But you don’t have to go it alone.

Understanding your legal rights is the first step. The next is taking action to protect them.
