The 14-hour rule bars a commercial truck driver from driving after 14 consecutive hours have passed since coming on duty, no matter how much of that time was actually spent behind the wheel. It is part of the federal hours-of-service regulations the Federal Motor Carrier Safety Administration enforces. It exists because tired drivers kill people. When a fatigued trucker causes a crash, our North Mississippi truck accident attorneys look hard at that clock, because the driver’s records often tell a very different story than the driver does.
How the 14-Hour Clock Actually Runs
The clock is not a driving limit. It is a window, and it starts the moment the driver goes on duty after 10 consecutive hours off. Everything inside that window counts against it: pretrip inspections, loading, waiting at a dock, fueling, paperwork, and lunch. A three-hour wait to get unloaded burns three hours of the window even though the truck never moved. Once the fourteenth hour passes, driving stops until the driver takes another 10 consecutive hours off.
Several separate limits run at the same time, and a driver can comply with one while violating another:
- A driver may not drive without first taking 10 consecutive hours off duty.
- A driver may not drive after a period of 14 consecutive hours after coming on duty following those 10 hours off.
- Inside that window, total driving time is capped at 11 hours.
- Once more than eight hours of driving time have passed without a consecutive 30-minute interruption in driving status, driving is not permitted, unless the driver qualifies for one of the short-haul exceptions.
- On top of the daily limits, a driver may not drive after 60 hours on duty in seven consecutive days, or 70 hours in eight consecutive days, depending on whether the carrier runs every day of the week.
- Either weekly period may end with the beginning of an off-duty period of 34 or more consecutive hours.
Those numbers matter in a crash case because they are objective. A driver’s memory of a long day is arguable. A timestamp is not.
Which Drivers and Trucks the Rule Covers
The federal safety regulations apply to employers, employees, and commercial motor vehicles transporting property or passengers in interstate commerce. The 14-hour rule described above is the property-carrying version, which is what governs the interstate tractor-trailer traffic on Interstate 55 and Interstate 269 through DeSoto County. Passenger-carrying operations run on separate limits, so the numbers above do not transfer. FMCSA publishes a plain-language table comparing the daily and weekly limits for each group.
The exceptions are where these cases get fought, and a carrier’s lawyer will reach for them early. Three come up repeatedly.
- A short-haul driver who stays within a 150 air-mile radius of the normal work reporting location, returns there, and is released within 14 consecutive hours is exempt from both the logging requirements and the supporting-document rules. The carrier still has to keep time records.
- A driver who hits genuinely adverse driving conditions may drive up to two additional hours beyond the normal maximum to finish the run or reach a safe place.
- A driver using a sleeper berth can split rest into two qualifying periods, in which case the rest time does not count inside the 14-hour window at all.
None of those exceptions is a blank check. Each has conditions written into the regulation, and whether a driver actually met them is a factual question the records usually answer.
Why a Violation Matters After a Crash
A violation does not decide the case by itself. Proving a Mississippi negligence claim still requires showing that the driver owed a duty, breached it, proximately caused the harm, and that the harm produced damages. What the hours records do is give a jury something concrete to weigh when it decides whether the driver and the company behaved reasonably.
Mississippi also applies pure comparative negligence, so contributory negligence does not bar recovery, and damages are instead diminished by the jury in proportion to the fault attributable to the injured person (Miss. Code Ann. §11-7-15). Most personal injury claims in Mississippi must be brought within three years of accrual under Miss. Code Ann. §15-1-49, which is the catch-all period for actions with no other limitation prescribed. Some claims run on shorter deadlines. Waiting three years to start investigating is still a serious mistake, for the reason in the next section.
The Records That Prove It, and the Six-Month Clock
Since December 18, 2017, most motor carriers have had to install electronic logging devices (ELD) and require drivers to use them. A few narrow exceptions survive, including drivers who complete a record of duty status on not more than eight days in any 30-day period, certain driveaway-towaway operations, and trucks manufactured before model year 2000.
The ELD is only the beginning. Carriers must also retain supporting documents that verify the driver’s on-duty not driving time:
- Each bill of lading, itinerary, schedule, or equivalent document showing the origin and destination of the trip
- Each dispatch record or trip record
- Each expense receipt related to on-duty not driving time
- Each electronic mobile communication record sent through a fleet management system
- Each payroll record or settlement sheet showing payment to the driver
A carrier generally does not have to keep more than eight of these documents for any one driver’s 24-hour period. It must keep the ones bearing the earliest and latest time indications among the eight it retains. Toll receipts sit on top of that cap for any period the driver used paper logs. Read together, these records let an investigator rebuild the day and test it against the log.
Here is the part that ends cases before they start. A motor carrier must retain records of duty status and supporting documents for a period of not less than six months from the date of receipt. Six months, not three years. No motor carrier or driver may obscure, deface, destroy, mutilate, or alter existing information in a supporting document, and neither may make a false report or tamper with an ELD so it fails to record accurately.
After six months, the regulations stop requiring the carrier to keep them. A prompt letter demanding preservation is often the difference between a provable fatigue case and a swearing contest.
When the Trucking Company Shares the Blame
Drivers rarely run out of hours by accident. They run out because a delivery window was set by someone who never had to drive it. Federal law addresses that conduct directly.
A motor carrier, shipper, receiver, or transportation intermediary, including their agents, officers, and representatives, may not coerce a driver into operating a commercial motor vehicle in violation of the safety regulations. The remedy the regulation itself provides is a written complaint to FMCSA rather than a lawsuit, so it is not a claim you file. It matters because it establishes what the company was required to do.
Separately, every employer must be knowledgeable of and comply with the regulations applicable to its operations, and every driver and employee must be instructed regarding them. A carrier that dispatched a load no lawful driver could deliver on time, or that never audited the logs it was holding, created that compliance problem itself. Where a crash takes a life, those same records support a Mississippi wrongful death claim against the company as well as the driver.
Talk to a Lawyer While the Records Still Exist
If a commercial truck hurt you or someone in your family anywhere in North Mississippi or the Memphis area, the driver’s logs are already on a six-month timer. The first move in a fatigue case is a written demand that the carrier preserve the electronic logs, the duty-status records, and the supporting documents behind them, sent before routine deletion becomes lawful.
The work after that is reading those records against each other, so the dispatch record, the receipts, and the delivery window can be tested against the hours the driver actually had left.
