How Skipped Rest Breaks Can Shape Liability After a Semi-Truck Crash
Key Takeaways: A trucker who skipped required breaks may give you strong evidence of fault in a Memphis crash, but the violation alone usually does not decide the case. Federal hours-of-service rules and Tennessee’s driver-hour statute limit driving time and require rest periods, and breaking them may help prove the driver failed to use reasonable care, possibly under negligence per se. You still generally have to show that the driver’s fatigue caused the crash and your injuries, using evidence like ELD data, logs, black box data, GPS and fuel receipts, and dispatch records. Many of these records can be lost or overwritten quickly, so sending a preservation letter early matters. The trucking company may also share the blame if it pushed unsafe schedules or ignored log violations. Tennessee generally allows only one year to file a personal injury or wrongful death lawsuit, so acting quickly is important.
Yes, a trucker who skipped required breaks may give you strong evidence of fault, but a skipped break alone generally does not decide a case. Federal and Tennessee hours rules exist to keep exhausted drivers off the road. If records show a driver broke those rules, that evidence may help show the driver failed to act with reasonable care. You still usually have to connect the violation to the crash and your injuries. For families dealing with a serious injury or death after a Memphis truck crash, knowing how an HOS violation fits into the case can help you protect evidence before it disappears.

What the Hours-of-Service Rules Require
Hours-of-service (HOS) rules limit how long commercial drivers may drive and require rest periods to prevent fatigue. These rules come from the Federal Motor Carrier Safety Administration (FMCSA) and appear in 49 C.F.R. Part 395. Because they are federal, they generally apply the same way to interstate commercial drivers in Memphis as elsewhere, subject to certain exceptions. FMCSA’s hours-of-service regulatory guidance explains the rules exist so drivers are not too tired to drive safely.
The 30-Minute Break Rule
The 30-minute break rule is often the rule at issue when people say a trucker "skipped a break." Under current federal rules, a property-carrying driver generally must take a break of at least 30 consecutive minutes after 8 cumulative hours of driving without such an interruption. Since 2020, the break can be taken off duty, in the sleeper berth, or on duty but not driving. Some exceptions apply, including certain short-haul operations. The rule has changed over the years, so knowing which version applied on the date of your crash can matter.
Other HOS Limits That May Apply
The break requirement is one of several separate HOS rules, and each one may support a violation claim. FMCSA’s rulemaking has also addressed the split sleeper-berth provision and the short-haul exception, as described in the SBA Office of Advocacy’s summary of proposed HOS rule changes. Common federal limits for property carriers include:
- An 11-hour driving limit after 10 consecutive hours off duty
- A 14-hour on-duty window, after which the driver generally may not drive
- A 60-hour/7-day or 70-hour/8-day cumulative on-duty limit
- Sleeper-berth and short-haul rules that change how these limits are counted
Tennessee’s Own Driver-Hour Statute
Tennessee also has a state statute limiting driving time and requiring drivers to keep logs. Under Tenn. Code Ann. § 55-20-204(a), a covered driver may not drive more than 12 hours after 8 consecutive hours off, or once combined on-duty and drive time reaches 15 hours since the last 8 hours off, or if total on-duty and drive time exceeds 70 hours in any 8 consecutive days. Section 55-20-204(b) requires the driver to keep a current daily log book, carry the past 30 working days of logs while on duty, and show them to law enforcement on request. Whether this statute applies depends on the driver and operation involved, and interstate drivers are generally governed by the stricter federal rules, so it should be checked against your case’s facts.
Proving Fault in an Hours of Service Violation Truck Accident
To prove fault, you generally must show duty, breach, causation, and damages, and an HOS violation mainly helps with the breach element. Truck drivers and motor carriers generally owe others on the road a duty of reasonable care. Records showing a driver went past legal limits or skipped a required break may help show that duty was breached. On its own, though, a violation generally does not prove the fatigue caused the collision.
Negligence Per Se in Tennessee
Tennessee courts may treat breaking a safety statute or regulation as negligence per se under certain circumstances. Generally, the plaintiff must show the defendant violated a law setting a specific standard of conduct meant to protect the public, the injured person belongs to the protected group, and the violation was a proximate cause of the injury. The Tennessee Supreme Court discussed these elements in Whaley v. Perkins, 197 S.W.3d 665 (Tenn. 2006). HOS rules are meant to prevent fatigue-related crashes, so courts may consider a documented violation in this framework. The result depends on the facts and how the court applies the doctrine.
Connecting Fatigue to the Crash
Causation is often where these cases are won or lost. Defense lawyers may argue the driver was alert despite the violation, or that something else caused the collision. Evidence such as late braking, drifting across lanes, a rear-end impact with no sign of braking, or a crash in the early morning hours may help show fatigue played a part. Witness statements and the driver’s own words at the scene can also matter.
💡 Pro Tip: Write down everything you remember about how the truck moved before the crash, such as swerving, sudden lane changes, or no braking. Those details may later line up with the driver’s log data.
The Evidence That Shows an HOS Violation
HOS violations are usually proven through records, and many of those records are time-sensitive. Most interstate trucks must use electronic logging devices (ELDs) that track driving time automatically, though some exemptions apply, such as for certain older vehicles and short-haul drivers. Federal record-retention periods are limited, and carriers may not keep some data past those periods. Acting quickly can make a real difference, as explained in our article on why many victims miss critical crash evidence.
| Evidence Source | What It May Show |
|---|---|
| ELD data | Driving time, duty status changes, missed breaks |
| Paper or electronic log books | Driver-reported hours, possible falsification |
| Engine control module ("black box") | Speed, braking, and throttle just before impact |
| Fuel, toll, and GPS receipts | Location and timing that may contradict logs |
| Dispatch records and messages | Delivery pressure from the carrier |
A preservation letter may be sent early to ask the carrier to keep these records. If a trucking company destroys relevant evidence after it should have expected litigation, courts may impose penalties in certain cases, such as an instruction letting the jury infer the evidence would have been unfavorable. Formal discovery in a lawsuit may also be used to get records the company does not share on its own.
When the Trucking Company Shares the Blame
An HOS violation may point to the carrier as well as the driver. Tight delivery schedules, dispatch pressure, or ignoring log violations may support claims against the company directly. Depending on the facts, a carrier may also be responsible for its driver’s negligence, including in some cases drivers operating under its authority through a lease arrangement.
Tennessee law gives plaintiffs a way to add parties who are identified later. Under Tenn. Code Ann. § 20-1-119(a)(1), if a defendant’s answer alleges that a non-party caused or contributed to the injury, the plaintiff may amend the complaint or file a separate action against that person within 90 days of the first answer making that allegation, even if the regular limitation period has run. This deadline is strict, and courts generally apply it according to its terms.
Deadlines That Can Affect Your Hours of Service Violation Truck Accident Claim
Tennessee generally gives injured people only one year to file a personal injury lawsuit. That deadline comes from Tenn. Code Ann. § 28-3-104(a)(1), one of the shortest in the country. Wrongful death claims generally follow the same one-year period. Under § 28-3-104(a)(2), the period may extend to two years in limited situations, such as when the at-fault driver is criminally charged for the conduct that caused the injury, but you should not rely on this without legal advice.
Other limitation periods may apply depending on how a claim is framed. For example, Tenn. Code Ann. § 28-3-105 sets a three-year period for certain actions, including property damage claims and some civil actions based on statutes creating monetary liability when no other deadline is fixed. Whether a longer period applies to any part of your case depends on the specific claims. Courts often read exceptions and tolling rules narrowly, and you should not assume an extension applies. A civil lawsuit is also separate from any FMCSA or state enforcement action against the driver or carrier.
Frequently Asked Questions
1. Does an HOS violation automatically make the trucker at fault?
No. A violation may be strong evidence of breach, and courts may consider it under negligence per se. You generally still have to show the violation or the driver’s fatigue caused the crash and your injuries.
2. What if the driver’s logs look perfect?
Logs can be wrong or falsified. Fuel receipts, GPS data, toll records, and dispatch messages may show a different timeline than the one the driver reported.
3. Can I recover if I was partly at fault?
Possibly. Tennessee follows modified comparative fault, established in McIntyre v. Balentine, 833 S.W.2d 52 (Tenn. 1992). You may generally recover if your share of fault is less than 50%, but your award is reduced by your percentage of fault.
4. How long does the trucking company keep ELD records?
Federal rules generally require carriers to keep records of duty status and supporting documents for six months. Some data may be lost sooner or overwritten, which is why early preservation requests matter.
5. Can I sue the trucking company and not just the driver?
In many cases, yes. Depending on the facts, the carrier may be responsible for its driver’s conduct or for its own negligent practices, such as pushing unsafe schedules.
Protecting Your Rights After a Fatigue-Related Crash
Evidence that a trucker skipped required breaks or drove past legal limits may help prove fault, but it works best as part of a larger, well-documented case. Federal HOS rules, Tennessee’s driver-hour statute, and the state’s negligence principles may all apply. Short deadlines and perishable electronic records mean timing matters. Working with an hours of service violation truck accident lawyer may help you find out what the records show before they are gone.
