A truck case takes one to three years, and the outlier catastrophic files run past five. The reasons sit in the structure of the litigation rather than in court congestion. National Safety Council figures put large-truck deaths at 5,340 in 2024 and large trucks involved in injury crashes at 120,724. That second number gets miscredited to FMCSA constantly.
FMCSA’s MCMIS series counts a narrower set, roughly 60,000 trucks in injury crashes across recent published years, and the agency’s most recent Crash Facts edition covers 2022. A citation to FMCSA for a 2024 six-figure count points at a dataset that does not carry it.
The Defendant List Sets the Clock
A single truck crash can involve several potentially responsible parties, including the driver, motor carrier, contracting company, freight broker, shipper, maintenance provider and manufacturer of a defective component.
Each name adds a document production, a deposition schedule, a set of cross-claims among defendants and a separate insurer with separate counsel.
The Investigation Is Most of the Timeline
Very little of the elapsed time happens in a courtroom. It goes into driver qualification files, hours-of-service records, pre-trip inspection reports, maintenance and repair orders, the carrier’s FMCSA safety history and post-crash testing records.
Connecticut practitioners have written this sequence out in detail. Weber & Rubano’s walkthrough of how a truck accident investigation proceeds in that state moves through scene evidence, police reports, the driver’s background, carrier records and electronic data in the order those pieces actually get pulled.
Louisiana Rewrote Its Rules Recently
Understanding your case is important so you can make a better decision about what you should and should not do after an accident. The lawyers at the law firm on https://murphylawfirm.com/ believe in holding responsible parties accountable and fighting for justice.
Anyone working from older Louisiana material is working from rules that no longer apply, and the three changes do not all run the same direction.
Prescription is no longer one year. Act 423 of 2024 repealed Civil Code articles 3492 and 3493 and enacted article 3493.1, setting a two-year liberative prescription for delictual actions effective July 1, 2024. It runs prospectively, so damage sustained before that date keeps the old one-year period.
Louisiana has also tightened its direct-action rules. Under Act 275 of 2024, effective August 1, 2024, an injured person generally cannot sue an insurer directly unless one of seven exceptions applies. The law also limits when the insurer can be named in the case and limits when the jury learns coverage exists, since Act 275 repealed Code of Evidence article 411(D).
What the Black Box Actually Records
The recurring claim that a truck’s module captures the last thirty seconds before a crash matches no published window. Real ones run from about 15 seconds to well over a minute depending on the engine.
Recording is triggered by a deceleration threshold rather than by the collision itself. Seven miles per hour in one second is the common Detroit hard-brake figure and Cummins uses nine, though fleets can often set the number themselves.
Windows and retention vary by engine maker. Cummins’ sudden deceleration reports carry 59 seconds before the trigger and 15 after. Detroit Diesel records about a minute before the trigger. Caterpillar retains one event, Detroit, Mercedes and Mack two, and Cummins three.
The practical consequence is the opposite of reassuring. A crash without hard braking may leave no event record at all, and the next hard stop overwrites what is there.
Fault Rules Set the Negotiating Posture
There are 10 or 11 states still running pure comparative fault, a count that dropped when Florida left in 2023 and Louisiana in 2026. More than 30 bar recovery once the plaintiff reaches 50 or 51 percent. Alabama, Maryland, North Carolina, Virginia and the District of Columbia keep contributory negligence, where one percent ends the claim, though DC carves out cyclists and pedestrians under a 2016 statute.
A carrier’s insurer in a contributory negligence jurisdiction will litigate a thin fault argument all the way to a verdict, because the payoff is total rather than proportional. That single doctrinal fact adds years to files that would settle in months elsewhere.
Truck cases move at different speeds because each one carries its own mix of defendants, records, injuries and state rules.
