FMCSA Regulation · Driver Fatigue
Driver Fatigue in Texas Truck Accidents
Driver fatigue is one of the leading causes of catastrophic truck accidents. A drowsy trucker has slower reaction times, impaired judgment, and a high risk of microsleeps — brief, involuntary lapses of attention that at highway speeds can cover hundreds of feet. Fatigue is often the result of a carrier pushing a driver past the legal hours-of-service limits, an unrealistic delivery schedule, or a driver who skipped a required rest break. If the truck that hit you showed no sign of braking or evasive action before impact, fatigue may be the cause — and proving it may materially affect the evaluation of an individual claim.

How fatigue impairs a truck driver
Research shows that after 17 hours awake, a driver's impairment equals a blood alcohol concentration of 0.08% — the legal limit for intoxication. After 24 hours awake, it equals 0.10%. A fatigued driver has slower reaction times, impaired attention, poor judgment, and a high risk of microsleeps — involuntary lapses of 3 to 15 seconds during which the driver is effectively asleep with their eyes open. At 65 mph, a 4-second microsleep covers nearly 400 feet. If the truck that hit you made no evasive maneuver — no braking, no swerving — before impact, fatigue is a primary suspect.
What causes truck driver fatigue
Driver fatigue can have multiple potential causes, including schedule, hours worked, sleep, medical conditions and time of day. Whether carrier, dispatcher or driver conduct creates civil responsibility depends on the specific duty, evidence, causation and applicable law.
How to prove driver fatigue caused your crash
ELD records may help document recorded driving and duty status, subject to the data, edits, exemptions and other evidence. If the ELD shows the driver was at or near the 11-hour limit, had been on duty for close to the 14-hour maximum, or had not taken the required 30-minute break, the records may raise a fatigue question that must be evaluated with the surrounding evidence. The dispatch records, the bill of lading with pickup and delivery times, and the fuel receipts can corroborate the actual driving hours. If the driver has a history of fatigue-related violations or a known sleep apnea diagnosis, that history may be relevant subject to admissibility, causation and the specific facts. Preservation needs for these records depend on their retention requirements, technical availability, the circumstances and applicable law.
The truck's event recorder and dashcam
Many modern trucks are equipped with event data recorders (EDRs) that capture speed, braking, and steering inputs in the seconds before a crash, and with dashcams that record the road ahead. If the EDR shows the truck made no braking input before impact, or if the dashcam shows the truck drifting within the lane before the crash, that evidence may be relevant to evaluating fatigue or attention, but it does not establish the cause by itself. These devices also capture hard-braking events and lane-departure warnings in the hours before the crash, which can show a pattern of fatigue. Retention and technical availability of vehicle and video data vary by system, so preservation needs should be evaluated from the specific circumstances.
Who is liable for a fatigue-related crash
Responsibility for a fatigue-related crash depends on the evidence connecting the driver, carrier, dispatcher or other party to the conduct and collision. Any applicable insurance must be identified and verified. Evidence of fatigue or an hours-of-service violation may be relevant to a negligence or exemplary-damages theory depending on the facts, causation, admissible evidence, and applicable Texas law.

Frequently asked questions
How do I prove the truck driver was fatigued?
The ELD record shows how many hours the driver was on the road. If the driver was at or near the legal limit, had skipped a required break, or had been on duty for close to the 14-hour maximum, the records may raise a fatigue question that must be evaluated with the surrounding evidence. The dispatch records, bill of lading, fuel receipts, and the truck's event data recorder can corroborate the finding. Preservation needs depend on the particular records, circumstances and applicable law.
Can a trucking company be liable for driver fatigue?
Such facts may be relevant, but carrier or dispatcher liability requires the applicable legal elements, evidence and causation; scheduling pressure or a medical-certification issue does not automatically establish liability.
Is a fatigued truck driver as dangerous as a drunk driver?
Research shows that after 17 hours awake, a driver's impairment equals a blood alcohol concentration of 0.08% — the legal limit. After 24 hours, it equals 0.10%. A fatigued truck driver is extremely dangerous, especially at highway speeds.
How much is a fatigue-related truck accident worth?
Evidence supporting fatigue may be relevant to responsibility and other legal theories, but its civil effect depends on causation, the applicable duty and other evidence. Any exemplary-damages theory requires the applicable Texas legal elements and evidentiary standard.

How much is an 18-wheeler accident settlement worth in Texas?
18-wheeler claims tend to be different from typical car accidents because of the severity of injuries and the potentially different commercial insurance arrangements involved. There is no dependable typical settlement range. An individual evaluation considers documented injuries, treatment, recovery, responsibility, commercial insurance coverage, wage loss, supporting evidence, and other case-specific facts. Use our free estimator for a broad educational preliminary range based on your treatment and coverage.
What is the minimum insurance for an 18-wheeler?
Financial-responsibility requirements and actual commercial coverage vary by operation, cargo and policy. Our estimator considers the coverage information you report, but actual policies and limits require verification.
Who is liable in an 18-wheeler accident in Texas?
Depending on the facts and applicable law, potentially responsible parties may include a driver, motor carrier, vehicle owner, cargo company, maintenance contractor, broker or product manufacturer. The evidence and verified policies determine which parties and coverage may actually apply.
How long do I have to file an 18-wheeler accident claim in Texas?
Texas personal-injury limitations commonly begin with a two-year period, but accrual, tolling, notice requirements, parties and claim type can change the analysis. Vehicle and duty-status records may have source-specific retention or availability considerations.
