Big-rig crashes aren’t just bigger car wrecks. They’re governed by a thick book of federal safety rules — and a violation of those rules can be the key that unlocks the trucking company’s liability, not just the driver’s.
Commercial trucks are governed by the Federal Motor Carrier Safety Regulations (FMCSR) — and when a trucking company or driver breaks one of those rules and causes a crash, that violation can establish negligence and expose the company itself to liability.
An ordinary car wreck usually comes down to one driver’s carelessness. A truck crash is different: behind the driver sits a motor carrier, often a maintenance contractor, sometimes a broker or shipper — all of them bound by federal rules designed to keep an 80,000-pound vehicle from becoming a weapon. Those rules are also a roadmap for proving fault.
The regulations below are federal, enforced by the FMCSA, and Georgia adopts much of the same framework for many intrastate carriers. The common thread for an injured person: each rule, when broken, isn’t just a paperwork problem — it’s evidence.
Fatigue is one of the deadliest factors in trucking, so federal law strictly limits how long a driver can be behind the wheel.
A property-carrying driver generally may drive no more than 11 hours after 10 consecutive hours off duty, and may not drive beyond the 14th hour after coming on duty.
A 30-minute break is required after 8 cumulative hours of driving, and weekly limits cap driving at 60 hours in 7 days or 70 hours in 8 days.
Most drivers must record their hours with an Electronic Logging Device (ELD). (Confirm current limits and exceptions.)
How it affects a claim: The ELD doesn’t lie the way a logbook once could. If the data shows a driver blew past the 11- or 14-hour limit, that’s powerful evidence of fatigue-driven negligence — and it often points upstream to a carrier that scheduled or pressured an impossible run. That’s why this data is one of the first things to preserve.
Not everyone is allowed to pilot a commercial truck. Federal rules set who is qualified and how they must be vetted.
A driver must hold a valid Commercial Driver’s License (CDL) with the proper class and endorsements for the vehicle and cargo (Part 383).
Motor carriers must ensure each driver is qualified — including a driving-record check, a medical examination, and a qualification file (Part 391).
How it affects a claim: These rules open the door to negligent hiring, training, and retention claims against the company. If a carrier put an unqualified, unsafe, or improperly licensed driver on the road — or ignored a bad driving history — the company’s own conduct becomes part of the case, often a more substantial target than the driver alone.
How a truck is loaded changes how it stops, turns, and behaves in an emergency.
Cargo must be properly distributed and adequately secured so it cannot shift, leak, or fall (Part 392 / Part 393 securement rules).
Vehicles must meet federal equipment standards — brakes, lighting, tires, and other safety components.
Trucks must comply with applicable weight limits; overloading affects braking and control.
How it affects a claim: An improperly secured or overloaded trailer can cause a rollover, a jackknife, or a load spill that turns a near-miss into a catastrophe. These failures frequently implicate multiple parties — the carrier, the company that loaded the cargo, and the shipper — widening the field of responsible defendants.
A truck that isn’t maintained is a danger to everyone around it, so federal law requires systematic upkeep and records of it.
Every motor carrier must systematically inspect, repair, and maintain its vehicles and keep records of that maintenance.
Drivers must complete Driver Vehicle Inspection Reports (DVIRs) identifying defects, and defects affecting safety must be corrected before the vehicle is operated.
How it affects a claim: Brake failures and tire blowouts are rarely “just bad luck.” Maintenance records, DVIRs, and inspection histories can reveal a carrier that deferred repairs to keep a truck earning — turning a mechanical failure into a documented choice to cut corners on safety.
Truck cases aren’t car cases scaled up. They involve more defendants, a layer of federal law, far larger insurance, and electronic evidence that vanishes fast.
| Car accident | Truck accident |
|---|---|
| Usually one at-fault driver | Driver plus the carrier, maintenance provider, broker, shipper |
| State traffic law | State law and a layer of federal FMCSR safety rules |
| Standard auto policy limits | Large commercial policies — and more at stake for insurers |
| Evidence is mostly the scene | ELD logs, engine/ECM data, DVIRs, qualification files — quickly overwritten |
ELD hours data, engine control module (“black box”) data, dispatch records, and maintenance files can be overwritten, recycled, or routinely destroyed within weeks or months. A spoliation / preservation letter sent immediately — demanding the carrier preserve this evidence — is often the single most important early step in a truck case. Wait too long and the proof of a violation may be gone.
Usually not. The motor carrier and others are frequently the more significant defendants — through their own violations of the federal rules and claims like negligent hiring or maintenance.
It’s a starting point, not the whole story. The federal-rule violations that decide these cases often surface only after the ELD, ECM, and maintenance records are obtained — which requires acting before they’re destroyed.
The filing deadline is two years, but the evidence deadline is far shorter. Critical electronic data can disappear in weeks, so a preservation demand needs to go out fast — long before the statute of limitations matters.
This page explains federal and Georgia law in general terms and is not legal advice; reading it does not create an attorney-client relationship. The FMCSR are federal regulations summarized here for readability — consult the current 49 CFR and Georgia law for the complete, authoritative versions, as limits and rules change. Truck cases turn on evidence that is destroyed quickly, so speak with a licensed Georgia attorney as soon as possible.
