Key takeaways
- Truck driver fatigue can affect attention, reaction time, judgment, lane control, and stopping distance.
- Federal hours-of-service rules limit driving time and on-duty time for many commercial drivers.
- Electronic logging device data and driver duty-status records can be critical evidence after a crash.
- Fatigue cases often involve company conduct too: dispatch pressure, unrealistic delivery windows, ignored log problems, or pressure to keep moving.
- Important records can disappear or be overwritten, so preservation should happen quickly after a serious Indiana truck accident.
A tired truck driver is not just a tired driver. A fully loaded tractor-trailer can weigh tens of thousands of pounds, takes far longer to stop than a passenger car, and can cause devastating injuries when the driver misses traffic slowing ahead, drifts from a lane, or reacts too late.
Hours-of-service rules exist because fatigue is predictable. Long shifts, overnight driving, irregular schedules, tight delivery windows, and inadequate rest can all make a commercial driver less alert. When a serious truck crash happens in Indiana, one of the first questions should be whether the driver was legally allowed — and safely able — to be on the road.

What are hours-of-service rules?
Hours-of-service rules are federal safety rules that limit when and how long many commercial truck drivers may drive. For property-carrying commercial vehicles, 49 C.F.R. § 395.3[2] includes limits such as the 11-hour driving limit, the 14-hour on-duty window after coming on duty, required interruptions of driving time, and 60/70-hour limits over 7 or 8 days depending on the operation.
The details can be technical, and exceptions may apply. But the purpose is straightforward: drivers and motor carriers should not keep operating commercial trucks when fatigue creates an unreasonable safety risk.
Why truck driver fatigue is so dangerous
Fatigue can reduce alertness before a driver ever falls asleep. A fatigued driver may follow too closely, drift out of a lane, overlook stopped traffic, misread traffic signals, fail to check mirrors, or react too slowly to a hazard.
The Federal Motor Carrier Safety Administration explains that fatigue can result from inadequate sleep, extended work hours, strenuous activities, or a combination of factors, and that it can impair performance. FMCSA’s CMV driver fatigue guidance[3] notes that the Large Truck Crash Causation Study reported 13 percent of commercial motor vehicle drivers were considered fatigued at the time of their crash.
What records show whether a driver was fatigued?
Fatigue is not always obvious from the crash scene. The evidence often comes from records created before the crash. Depending on the facts, important records may include:
- Electronic logging device data.
- Driver records of duty status.
- Dispatch messages and delivery schedules.
- GPS, telematics, and route data.
- Fuel receipts, toll records, bills of lading, and weigh station records.
- Cell phone records and company communications.
- Dashcam or inward-facing camera footage.
- Pre-trip and post-trip inspection records.
- Prior hours-of-service violations, audits, or safety reviews.
These records can show whether the driver had enough off-duty time, whether the driver exceeded allowed driving time, whether the company knew about log problems, or whether the delivery schedule was unrealistic from the start.
Electronic logs and duty-status records
Federal rules require many commercial drivers to record duty status. 49 C.F.R. § 395.8[4] addresses records of duty status and the use of electronic logging devices in many commercial operations. The rule also addresses duty-status categories such as off duty, sleeper berth, driving, and on-duty not driving.
ELD evidence can be powerful because it may show times, locations, driving periods, edits, and compliance issues. But ELD data is not the only evidence. Logs should be compared against GPS data, fuel records, toll records, shipping documents, dispatch messages, phone records, and witness statements.
The trucking company’s role in fatigue cases
Fatigue cases are not always only about the driver. A motor carrier may share responsibility if it permitted or required unsafe driving, failed to monitor logs, ignored violations, pressured a driver to meet an impossible schedule, or failed to enforce safety rules.
Federal rules recognize that motor carriers have duties too. Under 49 C.F.R. § 390.11[5], when a driver duty or prohibition exists under covered regulations, the motor carrier must require the driver to observe it. In practical terms, a trucking company cannot treat hours-of-service compliance as the driver’s problem alone.

ELD retention and production rules can matter
Electronic logging device records should be preserved quickly. 49 C.F.R. § 395.22[6] addresses ELD requirements, including account management, proper login, calibration, driver information packets, record backup, and record production. The rule also requires motor carriers to retain a backup copy of ELD records for a period of time.
Even with retention rules, injured people should not wait. A preservation letter can demand that the trucking company preserve logs, edits, raw ELD data, supporting documents, dispatch communications, and related records before they are lost, overwritten, or narrowed.
Common crash patterns in fatigue cases
Truck driver fatigue may be involved when the crash pattern suggests late reaction or loss of attention. Examples include:
- Rear-end crashes into stopped or slowing traffic.
- Lane departures or shoulder drift.
- Failure to brake before impact.
- Crossing the centerline or median.
- Jackknife or rollover after delayed reaction.
- Crashes during overnight or early-morning hours.
- Crashes after a long delivery route or tight turnaround.
How fatigue evidence affects an Indiana truck accident claim
Fatigue evidence can affect liability, insurance coverage, settlement value, and trial strategy. If the driver violated hours-of-service rules, falsified logs, or drove despite obvious fatigue, that evidence may support negligence claims against the driver. If the company encouraged or ignored the conduct, it may support direct claims against the motor carrier.
Fatigue evidence can also help defeat blame-shifting. Trucking companies and insurers may argue that the injured person stopped too quickly, changed lanes, or failed to avoid the crash. Logs, vehicle data, dashcam footage, and reconstruction evidence may show the truck driver had enough time to respond but was too tired, distracted, or over-hours to react safely.
If fault is disputed, Indiana comparative fault issues may become important. We explain that issue more here: What If the Police Report Says You Are Partly at Fault in Indiana?
What should be preserved after a fatigued truck driver crash?
After a serious crash, a preservation demand should be broad enough to cover both driver records and company records. Depending on the case, that may include:
- ELD data, edits, annotations, and audit trails.
- Driver logs and supporting documents.
- Dispatch messages, delivery appointments, and route plans.
- GPS, telematics, ECM, and event data recorder information.
- Dashcam and inward-facing camera footage.
- Fuel, toll, weight, repair, inspection, and shipping documents.
- Driver qualification, training, and safety history records.
- Company safety policies and hours-of-service compliance audits.
How long do you have to act?
Most Indiana personal injury claims are subject to a two-year deadline under Indiana Code § 34-11-2-4[7]. But truck accident evidence may need to be preserved much sooner than that. If a government vehicle or public entity is involved, shorter notice requirements may apply.
Do not wait until the end of the limitations period to investigate driver fatigue. The most important records may be in the trucking company’s possession from the beginning.

Frequently asked questions
What are hours-of-service violations?
Hours-of-service violations occur when a commercial driver or motor carrier fails to follow rules limiting driving time, on-duty time, required breaks, or required off-duty periods. These violations can be important evidence after a serious truck crash.
How can you prove a truck driver was fatigued?
Fatigue may be proven through ELD data, driver logs, dispatch records, GPS data, fuel receipts, toll records, phone records, dashcam footage, witness statements, crash reconstruction, and company communications.
Can the trucking company be responsible for driver fatigue?
Yes. A motor carrier may be responsible if it permitted or required unsafe driving, ignored log violations, pressured the driver to meet unrealistic schedules, failed to monitor hours, or failed to enforce safety rules.
Do all truck drivers use electronic logging devices?
No. Many commercial drivers must use ELDs, but exceptions can apply. Even when an ELD exception applies, other records may still show driving time, duty status, route history, and fatigue-related evidence.
Why is early evidence preservation important in fatigue cases?
Fatigue evidence may be controlled by the trucking company and may include electronic data, logs, dispatch messages, GPS records, and video. Preservation letters should be sent early so important evidence is not lost or overwritten.
