Rested or Running on Empty? How Truckers’ Weekly Rest Rules Shape Your Case
Key Takeaways: A 34-hour restart is at least 34 straight hours off duty. Under federal hours-of-service rules, it generally resets a property-carrying truck driver’s 60-hour/7-day or 70-hour/8-day on-duty clock to zero. Missouri adopts these federal rules as state law under RSMo § 307.400, so they generally apply to both interstate and intrastate trucks, with a few narrow exemptions. If a trucker skips a proper restart or fakes one in the logs, that may be strong evidence of driver fatigue and negligence, though it does not prove fault on its own. Carriers that push drivers past the legal limits may share the blame and, in limited cases, face punitive damages. In Missouri, you generally must file a personal injury claim within five years and a wrongful death claim within three years. Carriers generally only have to keep hours-of-service records for six months, so act quickly.
A 34-hour restart is at least 34 straight hours off duty that generally lets a truck driver reset their weekly on-duty clock to zero. Federal hours-of-service rules limit when a commercial driver may drive after building up a set number of on-duty hours over a rolling week. If a trucker skipped a proper restart, or faked one in their logs, that may be strong evidence of driver fatigue in your claim. If you were hurt in a crash with a semi on I-35, I-29, or Highway 152 in the Northland, the driver’s rest history may become one of the most important parts of your case.

Understanding the 70 Hour DOT Rule and the Weekly Hours Reset
The 70 hour DOT rule generally bars property-carrying truck drivers from driving after they have been on duty 70 hours in any 8 days in a row. The federal rules in 49 CFR Part 395 set two versions. Drivers for carriers that don’t run trucks every day of the week are generally held to 60 hours over 7 days. Drivers for carriers that run trucks every day are generally held to 70 hours over 8 days. Once a driver hits that cap, they generally cannot drive again until enough hours roll off or they take a qualifying 34-hour restart.
The restart resets the week. Once a driver takes 34 straight hours off duty, their 60- or 70-hour count can start again from zero. Separate daily limits still apply, including the 11-hour driving limit and the 14-hour on-duty window. A long rest gives the body time to recover from early mornings, night driving, and long hauls.
Why These Limits Apply Even to Local Missouri Trucks
Missouri adopts these federal rules as state law. Missouri Revised Statutes § 307.400 makes it unlawful to operate a commercial motor vehicle unless it is "equipped and operated as required by Parts 390 through 397" of Title 49 of the Code of Federal Regulations. Part 395 falls within that range, so a trucker’s weekly hours and rest requirements are generally state-law duties too.
The statute also covers trucks that never cross state lines. RSMo § 307.400.1 applies "whether intrastate transportation or interstate transportation." That means a delivery truck that only runs between North Kansas City and Liberty generally still has to follow these limits. There are narrow exemptions, including certain intrastate solid-waste vehicles and farm-plated vehicles. Federal exceptions, such as the short-haul exception, can also change which limits apply.
Recent Changes to the Federal Hours of Service Rules
The Federal Motor Carrier Safety Administration last overhauled key hours-of-service rules in a final rule published June 1, 2020, which took effect September 29, 2020. That rule revised the 30-minute break requirement, the sleeper-berth split options, the short-haul exception, and the adverse driving conditions exception. The 34-hour restart itself did not change. These changes affect how hours are counted and recorded, which matters when determining whether a trucker was over the legal limit before a crash.
Why Trucker Rest Requirements Exist: The Science of Driver Fatigue
FMCSA rest rules are based on research on how fatigue affects commercial drivers. The agency says its research aims to reduce fatigue-related crashes involving commercial motor vehicles, and that research underlies the hours-of-service limits, including the 34-hour restart.
The research ties too little rest and disrupted sleep to higher crash risk. A driver who works overnight runs, sleeps during the day, and then goes straight back to work is fighting their own body clock. Slower reaction times, drifting between lanes, and missed brake lights can turn deadly when the vehicle weighs 80,000 pounds.
💡 Pro Tip: Fatigue rarely shows up on a police report. Officers may note "inattention" or "following too closely," but linking those mistakes to a missed restart usually takes a close look at the driver’s records for the full week before the crash.
How a Skipped Restart Can Strengthen a Missouri Truck Crash Claim
You can use an hours-of-service violation as evidence that a driver or carrier was negligent. If a driver went past 70 hours without a proper restart and then caused a wreck, that violation may help show they were too tired to drive safely. A violation alone does not automatically prove fault. The injured person generally still has to show that the violation helped cause the crash. Still, it can be strong evidence.
The Records That Tell the Story
Electronic logging device (ELD) data is often at the center of fatigue cases. Most interstate drivers must record their hours on ELDs, although some may use other records instead. Here are the records our team typically works to secure:
- ELD data showing on-duty, driving, sleeper-berth, and off-duty status
- Dispatch records and messages between the driver and the carrier
- Fuel receipts, toll records, and GPS data that we can check against the logs
- Delivery schedules and bills of lading that show time pressure
- Crash reports, roadside inspection reports, and the carrier’s safety records
Comparing these records is often how fake logs come to light. A "restart" on paper may mean little if fuel receipts put the truck in Joplin during that same window. Drug and alcohol testing records can matter too. Learn more in our article on the 32-hour drug test deadline.
When the Trucking Company Shares the Blame
Fatigue cases often point back to the carrier, not just the driver. A carrier is generally responsible for an employee driver’s negligence on the job. Dispatchers who push impossible schedules or managers who look the other way may also make the company directly liable, depending on the facts. A truck claim may involve several responsible parties, including the driver, the motor carrier, a broker, or a maintenance contractor.
Punitive Damages and Hours-of-Service Violations
Missouri allows punitive damages only in limited situations, and the bar is high. Under RSMo § 510.261, a plaintiff must prove "by clear and convincing evidence" that the defendant intentionally harmed the plaintiff without just cause or acted with "a deliberate and flagrant disregard for the safety of others." A plaintiff also generally cannot include a punitive damages claim in the first filing and needs the court’s permission to add it. Depending on the facts, a plaintiff may argue that knowingly faking logs or deliberately skipping required restarts meets that standard.
Holding a trucking company liable for punitive damages based on a driver’s conduct takes more. Under RSMo § 510.261, punitive damages against an employer are generally available only if:
| Basis for Employer Punitive Liability | What It Could Look Like in a Fatigue Case |
|---|---|
| A principal or managerial agent authorized the act | A manager told the driver to keep driving past the limit |
| The employer was reckless in hiring or keeping an unfit agent | The carrier kept a driver with a history of log violations |
| The agent was a manager acting within the scope of employment | A company manager who was also driving went past legal limits |
| The employer or a managerial agent ratified or approved the act | The company praised or rewarded the overtime run after the fact |
Proof that dispatchers encouraged hours violations may make a real difference here. These claims depend heavily on the facts, and outcomes are never certain.
Deadlines That Matter After a Kansas City Truck Accident
You must generally file most personal injury claims from a Missouri truck crash within five years. RSMo § 516.120(4) covers "any other injury to the person or rights of another, not arising on contract." Claims against government entities can carry shorter deadlines and notice rules. Five years sounds like plenty of time, but carriers generally only have to keep hours-of-service records for six months, so ELD data and logbooks may be gone long before the filing deadline.
Wrongful death claims have a shorter window. Under RSMo § 537.100, you must generally file a wrongful death action within three years after the cause of action accrues. Courts read exceptions narrowly, so don’t count on them.
💡 Pro Tip: A prompt preservation letter to the carrier can help protect ELD and dispatch data before routine deletion erases it.

Frequently Asked Questions
-
What exactly counts as a 34-hour restart?
A qualifying restart generally requires at least 34 straight hours off duty. Once complete, the driver’s 60- or 70-hour weekly clock generally resets. Any on-duty time during that window breaks the restart.
-
Does the 70 hour DOT rule apply to every truck driver?
No. It generally applies to commercial drivers whose carriers run vehicles every day of the week. Others fall under the 60-hour/7-day limit. Some drivers qualify for exceptions, such as the federal short-haul exception or the narrow exemptions in RSMo § 307.400.
-
Can I get a trucker’s logbook after a crash?
In many cases, yes, through the claims process or discovery in a lawsuit. Acting quickly helps because carriers generally only have to keep hours-of-service records for six months unless they receive a preservation request or expect a lawsuit.
-
Does an hours violation automatically mean the trucker was at fault?
No. A violation may be strong evidence of negligence, but a court or jury will generally still look at whether it caused the crash and at all the facts.
-
How long do I have to file a truck accident claim in Missouri?
Personal injury claims generally have five years under RSMo § 516.120(4), and wrongful death claims generally have three years under RSMo § 537.100, with limited exceptions.
Getting Answers About the Rest Rules Behind Your Crash
The 34-hour restart and the 70 hour DOT rule exist because tired truckers put everyone on the road at risk. When a driver skips required rest, the proof often lies in ELD data, dispatch messages, and receipts that can vanish if nobody acts. Missouri law generally makes these federal limits state requirements, and violations may support negligence claims and, in some cases, punitive damages claims.
