Drowsy driving is a silent but deadly hazard on Alabama roads. The National Highway Traffic Safety Administration (NHTSA) estimates that it contributes to hundreds of fatal crashes yearly, yet it remains one of the hardest types of negligence to prove, because tired drivers rarely admit they were falling asleep behind the wheel.

If you were injured in a crash and suspect the other driver was too tired to drive safely, don’t assume your case is weak. Drowsy driving can be proven in court with the right evidence and legal strategy.

Here’s how our Alabama car accident attorneys build strong cases, even without a direct admission from the driver.

The Challenge of Proving Drowsy Driving

Unlike drunk driving, which can be confirmed with breathalyzer results, or distracted driving, which might be caught on camera, drowsy driving often leaves no obvious trace.

The NHTSA estimates that drowsy driving is involved in approximately 91,000 police‑reported crashes each year, resulting in about 50,000 injuries and nearly 800 deaths annually.

But most drivers won’t say, “I was too tired to drive.” Therefore, it is essential to examine the circumstances surrounding the crash and gather as much evidence as possible to prove your case before the evidence disappears.

Types of Evidence Used in Court

Drowsy driving requires looking at the full context of the crash. That means collecting evidence that suggests the driver was too tired to be behind the wheel, such as:

Accident Scene Clues

Certain crash patterns can signal that a driver was fatigued or asleep at the wheel:

• No skid marks or signs of braking as if the driver never attempted to avoid the collision
• Drifting into oncoming traffic or veering off the road with no correction points to a lack of control
• Rear-end collisions at high speed suggesting the driver wasn’t alert enough to react

These physical signs help paint a picture of what the driver was (or wasn’t) doing in the moments before impact.

Witness Testimony

Eyewitnesses can provide critical insight into the driver’s behavior:

• Passengers in the other vehicle might report the driver nodding off or complaining about tiredness.
• Other motorists or bystanders may notice swerving, slow reaction times, or erratic lane changes.

Even brief observations can help establish a pattern of drowsiness.

Electronic Data

Today’s vehicles and devices often carry a digital trail:

• Cell phone records can show if the driver was awake for extended periods, especially overnight.
• GPS data might reveal long trips with minimal stops, suggesting fatigue.
• Vehicle Event Data Recorders (EDRs), also known as “black boxes,” can show sudden braking or a lack of steering input, consistent with sleepiness.

An experienced legal team can subpoena and analyze this data to support your claim.

Medical and Lifestyle Factors

Health issues and demanding work patterns often contribute to driver fatigue and may help establish drowsiness as a cause:

• Sleep disorders like sleep apnea or insomnia may make someone more prone to falling asleep while driving.
• Prescription medications with known drowsiness side effects (such as sedatives or antihistamines) can be a factor.
• Work schedules may indicate sleep deprivation, particularly for night shift workers or long-haul drivers.

Medical records, pharmacy logs, and employer timecards may help establish a timeline of fatigue and liability.

Expert Testimony

Crash reconstruction specialists and sleep medicine experts can testify to:

• How the crash likely happened based on vehicle damage and data.
• How long someone can drive before fatigue becomes dangerous.
• Whether a person’s condition or schedule made drowsiness likely at the time of the crash.

These experts can explain to a jury what the physical evidence alone cannot.

The Importance of Quick Investigation

Much of the evidence in a drowsy driving case can vanish quickly. Tire marks fade. Witnesses become harder to locate. Digital records may be overwritten. That’s why it’s critical to act fast after a crash.
