After a collision with a truck carrying heavy equipment, the police report may describe only the impact. It may say little about where the load sat on the trailer, whether it shifted, what the driver could see during a turn, or what the carrier knew about the rig before the trip. Those details can make a heavy haul case very different from a dispute between two passenger cars.
The term heavy haul can cover different vehicles and loads. The first task is to identify the tractor, trailer, cargo, carrier, and route involved in the particular crash. Weight alone does not establish fault. A useful investigation asks how the load and equipment affected the truck’s movement, what the driver did, and which records can test the accounts given afterward.
The load is part of the crash scene
A flatbed carrying machinery can behave differently from a box trailer. A shifting load may affect stability or maneuverability; a wide load can change clearance and turn geometry. Federal cargo securement rules require cargo to be contained, immobilized, or secured so it does not shift enough to impair a vehicle’s stability or maneuverability. Whether a rule applies and whether it was violated depend on the equipment and the actual load.
Photographs taken before a trailer is reloaded may show tie downs, load position, contact points, damaged equipment, and debris. Bills of lading, loading instructions, inspection notes, and communications with the shipper may explain who handled the cargo. Those materials are especially useful when a carrier later says the load played no role in the collision.
Heavy vehicles also need room to stop and turn. A claim that a smaller vehicle cut in front of the truck should be tested against lane positions, speed, sightlines, video, and the truck’s available stopping distance. A claim about a wide turn needs the same attention to the trailer’s path, nearby markings, and any escort or traffic control visible at the scene. The answer will come from measurements and records, not from a general assumption that the truck or the other driver must be at fault.
Records that explain what happened before impact
Electronic logging and dispatch records can place the trip in time and help examine a fatigue allegation. Federal hours of service limits apply to many property carrying operations, but a log entry should be read alongside fuel, toll, GPS, and dispatch data rather than in isolation. A schedule may also help explain when the load was picked up and who expected delivery.
Maintenance evidence matters if braking, tires, lights, steering, or another component may have contributed. Federal motor carrier maintenance rules address systematic inspection, repair, and maintenance. A repair history can show whether a problem was reported before the crash, while inspection of the actual vehicle may help distinguish an old defect from damage caused by the collision.
Video from the truck, a nearby business, or another road user can clarify movement in the seconds before impact. Vehicle data, driver records, cargo documents, and maintenance files may be held by different people or companies. Identifying the sources promptly gives each side a better chance to preserve them before normal operations change the truck or erase the data.

Who may be responsible
The driver and motor carrier are obvious places to start, but the evidence may also involve a loader, maintenance vendor, or another driver. Louisiana Civil Code article 2315 supplies the general fault based framework for damages. Assigning responsibility requires proof of the conduct that caused the injury; the presence of several companies on shipping paperwork does not by itself make all of them liable.
Comparative fault may be contested. The current text of article 2323 requires allocation of fault and bars recovery when the injured person’s negligence is 51 percent or more. Act 15 of 2025 took effect January 1, 2026. The crash date and governing law must be checked before applying that change to a particular claim.
Injury proof needs the same specificity as crash proof. Medical notes, follow-up care, work records, and the person’s actual limitations help explain what changed after the collision. A scan that shows no fracture does not resolve every possible injury, but neither does the size of the truck prove a particular medical diagnosis or the value of a claim.
Preserving the case without guessing at a deadline
Louisiana Civil Code article 3493.1 generally provides two years from injury or damage for qualifying delictual actions arising on or after July 1, 2024. Earlier incidents may follow prior law, and special claims or circumstances can have different deadlines. Different claims and defendants can require additional steps. If a federal employee or federal vehicle may be involved, the Federal Tort Claims Act presentment rule and its separate time limits may need early attention.
Medical care comes first. As soon as it is safe, keep the crash report information, photographs, witness contacts, carrier name, trailer markings, and any messages from insurers. Do not assume that a missing item makes the claim impossible. A lawyer can identify what evidence the carrier or another party may hold and which deadline applies.
