Truck Driver Fatigue and Hours-of-Service Crashes in Louisville

Reviewed by Larry Forman, Attorney

A tired driver at the wheel of an 80,000-pound truck is one of the most dangerous things on a Kentucky highway. Fatigue slows reaction time, narrows attention and can end in "micro-sleeps," a few seconds with the eyes closed at highway speed. Truck driver fatigue crashes tend to be rear-end crashes into slowed traffic and lane-departure crashes, often at night or before dawn, and often with no braking at all.

Federal law treats fatigue as a safety violation, not bad luck. It also holds trucking companies responsible when their schedules and pay push drivers past their limits. Here's how these cases work.

Federal law prohibits driving while fatigued

The core rule is simple: no one may drive a commercial truck when fatigue, illness or any other cause has reduced, or is likely to reduce, their alertness so much that driving is unsafe. And a motor carrier "shall not require or permit" a driver to do so (49 CFR 392.3).

That rule applies even when the driver is technically within the hours-of-service limits. A driver who has been awake most of the day before starting a shift can be legally "on time" and dangerously tired.

The hours-of-service limits in brief

For property-carrying trucks, the hours-of-service rules (49 CFR 395.3) require:

• 10 hours off duty before starting a shift
• No driving after the 14th hour since coming on duty
• No more than 11 hours of driving within that window
• A 30-minute break after 8 hours of driving
• No driving after 60 hours on duty in 7 days, or 70 hours in 8 days, until the driver takes 34 consecutive hours off to restart

Kentucky applies these rules to in-state trucking too (601 KAR 1:005). For what an electronic logging device records and how long companies must keep the data, see truck black box and ELD evidence.

Exceptions trucking companies lean on

• Short-haul drivers. Drivers who stay within a 150 air-mile radius and are released within 14 hours don't have to keep logs or use an ELD. The carrier must instead keep accurate time records for six months (49 CFR 395.1(e)). Local delivery and construction trucks often operate this way. See delivery vehicle crashes.
• Adverse driving conditions. Unexpected bad weather or traffic can allow up to two extra hours to finish a run (49 CFR 395.1(b)).
• Sleeper-berth splits. Drivers can split their 10 hours off into two rest periods, one of at least 7 hours in the sleeper berth and the other at least 2 hours (49 CFR 395.1(g)).

These exceptions have conditions, and they are often misused. A company that claims an exception has to prove the driver qualified for it.

When the trucking company is responsible

Fatigue is often a business problem, not just a driver problem. Federal rules put duties directly on the carrier:

• It must make drivers follow the rules. When a regulation imposes a duty on a driver, "it shall be the duty of the motor carrier to require observance" (49 CFR 390.11).
• It can't "permit or require" driving beyond the hours limits (49 CFR 395.3).
• It can't schedule impossible runs that can only be finished by speeding (49 CFR 392.6).
• Falsified logs and tampered ELDs are prohibited for both drivers and carriers (49 CFR 395.8(e)).
• Medical fitness. A driver can't be medically qualified with a diagnosed respiratory dysfunction "likely to interfere" with safe driving (49 CFR 391.41(b)(5)). Untreated sleep disorders can matter here.

Kentucky law lets you pursue the carrier both for its driver's negligence and for its own negligence in hiring, training, supervising or retaining the driver. See trucking company liability, our truck wreck page and why truck wrecks are different from car crashes.

Proving truck driver fatigue

Drivers rarely admit they were tired, and logs can be wrong. We compare the logs against everything else:

• ELD and engine data: drive time, speed, braking and lane departure. See black box evidence.
• Fuel, toll and weigh-station receipts, GPS and delivery records that show where the truck really was, and when
• Dispatch messages and delivery deadlines that show pressure to keep moving
• Phone records that show when the driver was awake
• Pay records. Per-mile or per-load pay can reward driving through fatigue.
• The driver's work history for the previous days, including other jobs
• Crash physics. No skid marks, drifting across lanes and a late or absent reaction all point to fatigue.
• Medical certification and sleep-disorder records

Much of this is in the carrier's control and can be lost quickly. A preservation demand needs to go out within days.

Why fatigue crashes are so severe

A distracted driver usually looks up in time to brake or swerve. A driver who has dozed off doesn't react at all. That's why fatigue crashes so often involve a truck hitting slowed or stopped traffic at full highway speed, drifting across the center line, or running off the road and back on. With a fully loaded truck, the forces involved are many times greater than in a car-on-car crash, and the people in the smaller vehicles take the worst of it.

What to do after a crash you think involved a tired trucker

1. Get medical care and keep every record.
2. Tell the police what you saw: drifting, no braking, the time of day.
3. Note the company name, DOT number and trailer number if you can do so safely.
4. Don't give a recorded statement to the trucking company's insurer.
5. Call a lawyer right away. Some hours-of-service records only have to be kept for six months, and dispatch messages and phone data can disappear sooner.

Fault, damages and punitive damages

Insurers may argue you stopped too suddenly or were in the truck's blind spot. Kentucky's pure comparative fault rule (KRS 411.182) reduces a recovery only by your share. Fatigue crashes into slowed traffic are often rear-end collisions where the truck is clearly at fault.

Fatigue crashes often cause brain injuries and deaths. See our wrongful death page. When a company knowingly pushed drivers past legal limits, punitive damages may be possible. Kentucky allows them against an employer only when it authorized, ratified or should have anticipated the conduct (KRS 411.184(3)).

Deadlines

Claims against the driver and carrier generally must be filed within two years of the injury or the last PIP payment (KRS 304.39-230(6)). The carrier only has to keep supporting hours-of-service documents for six months, so don't wait. See our statute of limitations guide.

How Forman & Associates handles fatigue cases

• Send preservation demands for ELD, dispatch, pay and GPS records
• Audit the logs against receipts and data
• Investigate the carrier's scheduling, pay structure and safety culture
• Pursue the company for its own conduct, not just the driver's
• Prepare for trial. Larry Forman has tried 50+ jury trials and won 95% of them.

Truck driver fatigue FAQs

How many hours can a truck driver drive in a day?

Up to 11 hours of driving within a 14-hour window, after 10 consecutive hours off duty, with a 30-minute break after 8 hours of driving. Weekly limits of 60 or 70 hours also apply.

Can a driver be fatigued even within the legal hours?

Yes. Federal law separately bans driving when fatigue makes it unsafe, regardless of the hours. A driver who didn't sleep before a shift can be dangerous on day one.

Is the trucking company liable for a tired driver?

Often. Carriers must make drivers follow the rules, and they can't permit or require driving beyond the limits or schedule runs that require speeding. They can be liable for the driver's negligence and their own.

What if the driver's logbook looks clean?

Logs can be wrong or falsified. We check them against fuel and toll receipts, GPS, dispatch messages and phone records.

Do local truck drivers have to keep logs?

Not always. Short-haul drivers within 150 air-miles who are released within 14 hours can skip logs. Their employer still has to keep accurate time records for six months.

How long do I have to file a claim after a crash with a tired trucker?

Generally two years under Kentucky's no-fault law. Some supporting hours records only have to be kept for six months, so act quickly.
