Drowsy Driving After Long Shifts: Nighttime Stats

Drowsy driving kills. The Texas Department of Transportation recorded hundreds of fatigue-related crashes across the state in a single recent year, and the numbers in Bexar County track the statewide pattern. For workers coming off long shifts — nurses, first responders, warehouse workers, truck drivers — the drive home is one of the most dangerous parts of the day.

I’m Jamie Shaw with Carabin Shaw in San Antonio. How long do you actually have to file a car accident claim in Texas? Generally two years from the date of the crash. Miss that deadline and the court can throw your case out, no matter how strong it is. People think two years is plenty, so they wait. But evidence disappears, witnesses forget, and the insurance company uses that delay against you. And watch out — claims against a government vehicle can have deadlines as short as six months. Don’t guess. If you’ve been hurt in a San Antonio crash, call Carabin Shaw. Free consultation and you pay nothing unless we win. 210-222-2288.

How Fatigue Impairs Driving as Severely as Alcohol

The San Antonio car accident attorneys at Carabin Shaw have handled fatigue-related crash cases where the at-fault driver had been awake for more than 20 consecutive hours. Research published by the Centers for Disease Control and Prevention (CDC) shows that being awake for 18 hours produces impairment equivalent to a blood alcohol concentration of 0.05 percent. At 24 hours without sleep, that equivalent rises to 0.10 percent — above the legal limit in Texas. The driver does not need to fall asleep at the wheel to be impaired. Slowed reaction time, narrowed attention, and reduced hazard perception are present long before a driver closes their eyes.

The Circadian Danger Zone

The human body has two natural periods of peak sleepiness: between 2 a.m. and 5 a.m., and between 1 p.m. and 3 p.m. The National Highway Traffic Safety Administration (NHTSA) reports that drowsy-driving crashes occur most frequently between midnight and 6 a.m. Shift workers who finish a night shift and drive home during the early morning hours are driving directly into the highest-risk window on the clock.

Which Workers Face the Highest Risk

Healthcare workers, commercial drivers, manufacturing workers, and emergency responders are the occupational groups most frequently involved in fatigue-related crashes. The American Nurses Association has documented that one in ten nurses reported being involved in an automobile accident they attributed to fatigue from shift work. Commercial truck drivers are subject to federal hours-of-service regulations precisely because the data on fatigue-related crashes in that industry is severe. When those regulations are violated and a crash results, the liability extends to the trucking company.

Proving Fatigue in a Crash Case

Fatigue does not show up in a blood test the way alcohol does. Proving that a driver was impaired by fatigue requires building a picture from multiple sources: employment records showing shift hours, time-stamped security footage from the workplace, cell phone data showing the driver was awake, witness accounts, and the crash reconstruction itself. The physical evidence of a fatigue crash — no braking before impact, a single-vehicle run-off-road, a crash in a straight-line section with no apparent hazard — tells its own story.

Nighttime Driving Compounds the Risk

Reduced visibility, glare from oncoming headlights, and the absence of the visual cues that help drivers stay alert during daylight hours make nighttime driving more demanding even for well-rested drivers. When a fatigued driver is added to those conditions, the risk multiplies. San Antonio’s highway network — I-35, Loop 410, US-281, I-10 — carries significant commercial and commuter traffic through the night. The stretch between midnight and 5 a.m. is when fatigue-related crashes on those corridors are most likely to occur.

Employer Liability in Fatigue Crashes

When an employer requires workers to drive after a shift that exceeds safe limits, or when a company vehicle is involved in a fatigue crash, the employer may share liability. Texas law recognizes negligent entrustment — allowing a fatigued employee to drive a company vehicle when the employer knew or should have known the driver was impaired. Building that case requires employment records, scheduling data, and any internal communications about driver fatigue policies.

What to Do After a Crash Involving a Drowsy Driver

The evidence that proves fatigue disappears quickly. Employment records are retained for limited periods. Surveillance footage is overwritten. Witness memories fade. A formal legal hold request sent to the at-fault driver’s employer within days of the crash can preserve records that would otherwise be gone. Medical documentation of every injury — including those with delayed onset like concussions and soft tissue damage — needs to start at the first treatment and continue without gaps.
