Tennessee Truck Driver Hours of Service Violations

Truck drivers are federally limited on how many hours they can drive before they’re required to stop and rest. These limits exist because fatigued driving kills people.

The FMCSA tracks the data. Drowsy truck drivers cause thousands of crashes a year. And when a trucking company or driver ignores the limits and you or your family pays the price, those violations don’t just prove the driver was tired. They prove negligence.

Here’s what the rules are, how violations get discovered, and why the trucking company — not just the driver — is usually the one that pays.

What the Federal Rules Actually Require

The Hours of Service regulations under 49 CFR Part 395 apply to most commercial truck drivers. The core limits:

• 11-hour driving limit. After 10 consecutive hours off duty, a driver can drive a maximum of 11 hours. Not 11 and change. Eleven.
• 14-hour window. A driver can’t drive past the 14th hour after starting their shift. This clock doesn’t pause for fuel, loading, or meals. It runs straight through.
• 30-minute break. Required after 8 cumulative hours of driving or on-duty time. Fatigue compounds fast — reaction time drops significantly after 8 hours without a break.
• 60/70-hour weekly cap. Drivers can’t exceed 60 on-duty hours in 7 days (or 70 hours in 8 days). A 34-hour restart period resets the clock.

These aren’t suggestions. Violating them carries fines, out-of-service orders, and damage to the carrier’s federal safety rating.

Why HOS Violations Matter So Much in a Tennessee Lawsuit

Tennessee is a fault-based state. To win a truck accident claim, you have to prove the other side was negligent — that they breached a duty of care and that breach caused your injuries.

An HOS violation does a lot of that work for you.

When a driver blows past the 11-hour limit and then crosses the center line into your car, that violation is evidence of negligence per se. That’s a legal term that means the violation of a safety statute creates a presumption the driver wasn’t being careful. A defense attorney has a hard time arguing “reasonable care” when federal records show 13 or 14 hours straight behind the wheel.

Under Tennessee’s comparative fault rule from McIntyre v. Balentine, 833 S.W.2d 52 (Tenn. 1992), the jury assigns fault percentages. An HOS violation stacks heavy weight against the driver and carrier. It also opens the door to punitive damages under T.C.A. § 29-39-104 if the company knew about the violations and let the driver keep running.

The Trucking Company Is Usually the Real Target

Drivers don’t usually violate HOS limits because they want to. They do it because the company sets schedules that make compliance impossible.

Dispatch says the load has to be in Memphis by morning. The math requires 14 hours of driving. The driver either misses the deadline or breaks the law. Most drivers break the law. The company knows this and looks the other way — or actively encourages it.

That’s why the trucking company is often the more important defendant:

• Respondeat superior makes the company liable for its driver’s negligence during the scope of employment. Driver was hauling a load? Company shares liability.
• Direct negligence applies when the company itself created the problem — setting impossible schedules, failing to review ELD data, pressuring drivers to falsify logs, or keeping drivers with chronic violations on the payroll.

The driver might carry a minimum insurance policy. The trucking company carries commercial coverage in the millions. That’s where the compensation actually comes from.

ELD Data Is the Smoking Gun

Before 2017, drivers tracked hours on paper logs. They were easy to fake. The industry called doctored logs “comic books.”

The ELD mandate changed that. Every commercial truck now carries a device wired to the engine that automatically records driving time, on-duty time, rest periods, and location. It’s timestamped, objective, and hard to manipulate.

ELD data tells us exactly:

• When the driver started their shift
• How many hours they drove
• Whether they took the required 30-minute break
• Whether they exceeded any federal limit
• Where the truck was at every point in the trip

This data is the single most important piece of evidence in a fatigued-driving case.

The problem is preservation. ELD data gets overwritten as new data comes in. Trucking companies are required to retain logs, but without a formal legal demand, data from the days around your crash can disappear fast.

An experienced attorney sends a spoliation letter within days of the accident — sometimes hours — demanding the company preserve all ELD records, dispatch logs, driver qualification files, and maintenance records. If the company destroys evidence after receiving that letter, it creates a separate legal problem for them that actually strengthens your case.

Other Evidence That Builds the Case

ELD data is the backbone, but a thorough investigation pulls from several other sources.

Dispatch records and load assignments show whether the delivery schedule was even possible within legal limits. If the math doesn’t work, the company built the violation into the job.

Driver qualification files show training, employment history, and prior violations. A driver with repeated HOS infractions who’s still employed tells the jury everything they need to know about the company’s priorities.

The FMCSA’s CSA database tracks carrier safety performance publicly. A pattern of violations across the fleet proves the problem is systemic — not a one-off mistake by a single driver.

Tennessee’s Filing Deadline and Why Speed Matters

The statute of limitations for personal injury claims in Tennessee is one year from the date of the accident under T.C.A. § 28-3-104. Wrongful death claims run one year from the date of death.

But the real deadline is evidence preservation. ELD data, dispatch communications, and driver files can vanish in weeks. Don’t wait months to call a lawyer. Call in days.
