The 11-hour driving limit under 49 CFR § 395.3 prohibits a commercial truck driver from driving for more than 11 hours after taking 10 consecutive hours off duty. When a truck driver exceeds this federal limit and causes a fatigue-related crash, electronic logging device (ELD) records, driver logs, and other evidence may help show that the driver or trucking company failed to follow required safety regulations.
At Colucci, Colucci & Marcus, P.C., our Boston truck accident lawyers handle serious commercial vehicle crash cases throughout Norfolk County and Greater Boston. Our attorneys handle truck accident claims involving driver fatigue, hours-of-service violations, and other commercial trucking negligence claims.
This guide explains what the 11-hour rule requires, how violations are proven through logging data, and what injured victims in Massachusetts can do next.

What Is the 11-Hour Driving Limit Under 49 CFR § 395.3?
A property-carrying truck driver may drive for a maximum of 11 hours, and only after taking 10 consecutive hours off duty. This federal cap comes from the hours-of-service (HOS) rules in 49 CFR § 395.3, enforced by the Federal Motor Carrier Safety Administration (FMCSA).
The 11 hours of driving must fit within a 14-hour on-duty window, which we explain below. Once a driver reaches 11 hours behind the wheel, they cannot drive again until completing another 10 consecutive hours off duty.
The rule is designed to reduce fatigue-related risks that can affect reaction time, judgment, and attention. A fully-loaded tractor-trailer can weigh up to 80,000 pounds, so driver fatigue can significantly increase the risk of a crash.
Key Takeaway: Under 49 CFR § 395.3, a commercial driver may drive no more than 11 hours after 10 consecutive hours off duty, and that driving must occur within a 14-hour on-duty window.
What Other Federal Hours-of-Service (HOS) Rules Apply to Truckers?
The 11-hour limit rarely stands alone. Drivers who break it often violate related HOS rules at the same time, and each violation adds to the evidence of negligence.
What Is the 14-Hour On-Duty Window?
A driver may not drive after 14 consecutive hours have passed since coming on duty, following 10 hours off. This window includes driving, loading, fueling, inspections, and waiting time. The clock does not stop for breaks. Once 14 hours elapse, the driver must stop operating the vehicle even if the driver has not used all 11 driving hours. This rule prevents companies from stretching a shift across an entire day.
What Are the 30-Minute Break and 60/70-Hour Rules?
A driver cannot drive past 8 cumulative hours of driving without a 30-minute break, which may be off-duty, sleeper berth, or on-duty not driving time. This mandatory pause is designed to reduce fatigue during long hauls.
Weekly limits also apply. A driver may not drive after 60 hours on duty in 7 consecutive days, or 70 hours in 8 consecutive days, depending on the carrier’s schedule. A driver can reset that weekly count by taking at least 34 consecutive hours off duty.
| Rule | Limit | What It Requires |
|---|---|---|
| 11-hour driving limit | 11 hours | Maximum driving after 10 consecutive hours off duty |
| 14-hour window | 14 hours | No driving after 14 consecutive hours since coming on duty following 10 hours off |
| 30-minute break | After 8 hours of driving | A 30-minute break before driving past 8 cumulative hours of driving |
| 60/70-hour limit | 60 hours in 7 days or 70 hours in 8 days | Weekly on-duty cap; resets after at least 34 consecutive hours off duty |
Key Takeaway: The 14-hour window limits a driver’s on-duty day, and the 60/70-hour rules limit total on-duty time to 60 hours in 7 days or 70 hours in 8 days, with a 34-hour restart available after at least 34 consecutive hours off duty.
Why Do Truck Drivers Violate the 11-Hour Limit?
Many violations trace back to economic pressure rather than carelessness alone. Drivers and carriers face financial incentives that reward speed over rest, which can contribute to hours-of-service violations.
Common reasons drivers exceed the 11-hour limit include:
- Pay-per-mile compensation, which rewards drivers for covering more distance and discourages rest stops
- Tight delivery schedules set by shippers and brokers that leave little room for legal breaks
- Falsified or “double” logbooks used to hide extra hours behind the wheel
- Driver fatigue, untreated sleep disorders, and cumulative exhaustion over consecutive long shifts
- Pressure from dispatchers to keep moving despite HOS deadlines
When a carrier ignores these warning signs or encourages drivers to break the rules, liability can extend well beyond the individual driver.
How Do Electronic Logging Device (ELD) Records Prove a Violation?
An Electronic Logging Device (ELD) automatically records a truck’s engine hours, movement, miles driven, and duty status. Because the device syncs with the engine, it produces objective data that is far harder to fake than a handwritten paper log.
Most covered commercial motor carriers were required to use ELDs by December 18, 2017, with limited exceptions for certain drivers and vehicles. These records can show when a driver started driving, when the driver crossed the 11-hour mark, and whether required breaks were taken.
ELD data is often the single most important piece of evidence in a fatigue-related crash. However, federal rules require motor carriers to retain records of duty status and supporting documents for at least six months, and ELD backup records must also be retained for six months. Sending a legal preservation letter and, when needed, a subpoena early can secure this evidence before it disappears.
Key Takeaway: ELD data provides objective, minute-by-minute proof of driving hours, but carriers must retain ELD records and records of duty status for only six months, so prompt preservation letters and subpoenas are often critical to proving an 11-hour violation.

How Does an 11-Hour Violation Prove Negligence in a Massachusetts Truck Accident?
To win a truck accident claim in Massachusetts, you must prove four elements: duty, breach, causation, and damages. A driver owes other motorists a duty of reasonable care, and the HOS rules define part of that standard for commercial operators.
An 11-hour violation can help establish the breach element of a negligence claim. When a driver keeps going past the legal limit and then causes a crash, that decision shows a failure to drive safely. If the resulting fatigue caused or contributed to the collision, the causation link becomes clear.
The final element, damages, covers the harm you suffered, your injuries, medical bills, and lost income. Together, these four elements establish the basis of a fatigue-related negligence claim.
Is an HOS Violation “Negligence Per Se” Under Massachusetts Law?
Massachusetts does not apply the strict “negligence per se” doctrine used in some other states. Under Massachusetts law, violating a safety regulation like the federal hours-of-service rules is treated as evidence of negligence that a jury may weigh, rather than an automatic finding of fault.
This distinction matters because the injured person still has to connect the HOS violation to the crash and resulting injuries. A documented 11-hour violation can provide significant evidence that a jury may consider when evaluating negligence.
Key Takeaway: In some states an HOS violation is negligence per se. Under Massachusetts law, it is treated as strong evidence of negligence that a jury may consider, not an automatic finding of fault.
Who Can Be Held Liable for an 11-Hour Rule Violation in Massachusetts?
Liability often extends beyond the driver. The trucking company may be responsible if it pressured the driver, ignored log violations, failed to supervise hours-of-service compliance, or set schedules that made legal rest breaks unrealistic.
The driver is directly liable for choosing to drive past the legal limit. The trucking company can be vicariously liable under the doctrine of respondeat superior, which holds an employer responsible for an employee’s negligence committed within the scope of employment.
A company may also face direct liability for negligent hiring, training, or supervision, for example, if it hired a driver with a history of log violations or set schedules that made compliance impossible. A broker or shipper may become relevant if evidence shows it contributed to an unsafe schedule or knowingly pressured a carrier to meet a delivery deadline that made HOS compliance unrealistic. Identifying every responsible party helps determine all available insurance coverage.
What Compensation Can You Recover After a Massachusetts Truck Accident?
Injured victims can typically recover both economic and non-economic damages. Truck crashes tend to produce severe injuries, so the amounts at stake are often substantial.
Recoverable damages generally include:
- Medical expenses, including emergency care, surgery, hospital stays, and future treatment
- Lost wages and lost earning capacity if your injuries keep you from working
- Pain and suffering for physical pain and emotional distress
- Property damage to your vehicle and personal belongings
Where a family loses a loved one, the Massachusetts wrongful death statute, M.G.L. c. 229, § 2, allows punitive damages in certain wrongful death cases involving gross negligence or willful, wanton, or reckless conduct. A serious HOS violation may help support that argument when the facts show more than ordinary carelessness.
Your recovery can be reduced if you share fault. Under M.G.L. c. 231, § 85, Massachusetts follows a modified comparative negligence rule: you can recover as long as you are not more than 50% at fault, though your award is reduced by your share of blame.
Key Takeaway: Massachusetts truck accident victims can typically recover medical bills, lost wages, and pain and suffering, plus punitive damages in wrongful death cases involving gross negligence. Compensation may be reduced under the state’s modified comparative negligence rule.
How Long Do You Have to File a Truck Accident Claim in Massachusetts?
You generally have three years from the date of the crash to file a personal injury lawsuit in Massachusetts. This deadline comes from the statute of limitations at M.G.L. c. 260, § 2A.
Limited exceptions may pause, or “toll,” the filing deadline, but those exceptions are fact-specific. Because Massachusetts generally gives most personal injury victims three years from the date the claim accrues, injured victims should not wait to preserve evidence or evaluate filing deadlines.
Key Takeaway: Massachusetts gives most truck accident victims three years from the crash date to file suit under M.G.L. c. 260, § 2A. Missing this deadline usually ends your right to recover compensation.

Frequently Asked Questions
What counts as “driving time” under the 11-hour rule?
Driving time is any period the driver is at the controls of a moving commercial vehicle. Loading, fueling, and waiting count toward the 14-hour window but not toward the 11 hours of actual driving.
Can a trucking company be fined for HOS violations?
Yes. The FMCSA can impose civil penalties on drivers and carriers for hours-of-service violations, and repeated violations can affect a carrier’s safety rating. Those enforcement records can also support a civil injury claim.
Do all truck drivers have to use ELDs?
Most interstate commercial drivers required to keep records of duty status must use an ELD. Limited exceptions exist, such as certain short-haul drivers and operators of older trucks, but the majority of long-haul drivers fall under the mandate.
What if the trucking company altered the driver’s logs?
Falsifying logs is itself a federal violation and can point to a cover-up. ELD data, GPS records, fuel receipts, and toll records can often expose discrepancies, and evidence of tampering may support sanctions, adverse inferences, or direct claims against the carrier.
Can I still sue if the crash happened just before the 11th hour?
Yes. A driver can be negligent even without exceeding a specific limit, for example, by driving while drowsy or ignoring the 30-minute break rule. A violation makes the case stronger, but it is not the only path to proving fault.
Does Massachusetts follow federal HOS regulations?
Yes. Interstate commercial carriers operating in Massachusetts must comply with the federal hours-of-service rules under 49 CFR § 395.3. Intrastate or exempt operations may require a closer review of the applicable state and federal rules.
What if I was partially at fault for the crash?
You can still recover as long as you were not more than 50% at fault under Massachusetts comparative negligence law. Your compensation is reduced by your percentage of fault, so being partly responsible does not automatically bar your claim.
