DROWSY DRIVING DEATHS ARE COUNTED TWO WAYS
Sleep Loss Kills People On The Road Every Year
Two Official Sources Disagree About How Many
Federal Crash Records Put It Near Six Hundred
Camera Based Research Puts It Near Six Thousand
Both Numbers Come From Serious Organizations
The Gap Is About Measurement Rather Than Opinion
Nothing At A Crash Site Proves A Driver Was Tired
This Part Covers Why The Count Falls Apart

THE TWO NUMBERS 🔢
Federal Traffic Safety Data Comes From Police Reports
Those Reports Listed Six Hundred Eighty Four Deaths In 2021
Recent Federal Estimates Run Closer To Eight Hundred
The AAA Foundation Ran A Different Kind Of Study
Investigators Reviewed Fatal Crashes From 2017 Through 2021
They Used In Vehicle Camera Footage Where It Existed
Drowsiness Appeared In Seventeen Point Six Percent Of Them
Applied To National Totals That Reaches Six Thousand
One Estimate Is Ten Times The Other
Neither Organization Is Guessing
Police Reports Record What An Officer Could Determine
Camera Footage Records What The Driver Actually Did
A Closing Eyelid Shows Up On Video
It Does Not Show Up In A Crash Diagram
The Two Methods Answer Different Questions
One Measures Documented Drowsiness
The Other Measures Observed Drowsiness
Only One Of Those Is The Real Number

WHY THE RECORDS MISS IT 📋
Alcohol Leaves Physical Evidence At A Crash
A Breathalyzer Produces A Number Within Minutes
Phone Records Show Whether Someone Was Texting
Sleep Loss Leaves None Of That Behind
Officers Have To Infer It From Circumstances
Many Crash Report Forms Have No Field For Drowsiness
Training On Recognizing It Is Not Standard
A Driver Who Survives Rarely Volunteers The Detail
Admitting Fatigue Can Affect Insurance And Liability
A Driver Who Dies Cannot Be Asked
Single Vehicle Crashes Get Coded As Loss Of Control
Loss Of Control Is A Description Rather Than A Cause
The Category Absorbs Cases Nobody Investigated Further
Reporting Practice Also Varies Between States
A National Total Built From That Is Not Stable
Comparing This Year To Last Year Compares Paperwork
Whether The Real Figure Is Rising Cannot Be Answered
The Data Was Never Built To Answer It

THE DEATHS THAT DID GET NAMED ⚓
Some Investigations Did Name Fatigue Directly
The Exxon Valdez Grounded In Alaska In 1989
Federal Investigators Examined The Crew Schedules
Their Report Named Fatigue As A Contributing Factor
Company Overtime Rules Appeared In The Same Finding
Eleven Million Gallons Of Oil Reached The Water
Three Mile Island Began Around Four In The Morning
Night Shift Operators Missed What Was Happening
Later Reviews Attributed Part Of That To Fatigue
The Challenger Launch Decision Came After A Long Night
Managers On The Teleconference Had Slept Very Little
The Presidential Commission Recorded That In Its Findings
Each Case Produced Recommendations About Working Hours
Driving Hour Limits For Truckers Did Tighten Afterward
Hospital Training Hours Were Capped In 2003
Enforcement Of Those Caps Remains Inconsistent
Named Disasters Changed More Than Uncounted Deaths Did
Six Thousand Roadside Cases Produced No Equivalent Rule
