Box trucks range from rental moving vehicles and local service trucks to carrier-operated freight vehicles. The same body style can be used for a household move, retail delivery, interstate shipment, contractor job, or personal trip. The investigation begins by identifying the vehicle and operation.

A box-shaped cargo body does not determine the applicable safety rule, carrier, insurance policy, or cause of the collision.

Classify the vehicle and trip

  • Vehicle identification, title, registration, configuration, gross and actual weight, ratings, and cargo
  • Owner, renter, lessee, driver, employer, contractor, carrier, shipper, broker, and customer
  • Origin, destination, route, dispatch, delivery or moving task, compensation, and business purpose
  • Driver license, endorsements, restrictions, qualification, medical status, and assigned work
  • Intrastate or interstate movement and any claimed exception

49 C.F.R. § 390.5T contains definitions used in federal motor-carrier safety rules. Apply the relevant definition and rule to the actual vehicle, cargo, commerce, carrier, and trip instead of assuming every business truck receives the same treatment.

Preserve vehicle condition

Use photographs, reports, and data already obtained lawfully. Do not enter traffic or a restricted storage area, handle a damaged truck or cargo, or operate vehicle systems to document a claim. Qualified, authorized investigators should coordinate vehicle access, measurements, downloads, component examination, and testing with the evidence custodian.

49 C.F.R. § 396.3 addresses inspection, repair, maintenance, and records for covered motor carriers. Determine applicability and identify who inspected, repaired, possessed, and could remove the truck from service.

  • Brakes, tires, steering, suspension, lamps, mirrors, windows, doors, liftgate, and warning systems
  • Inspection reports, defect notices, work orders, invoices, fault codes, complaints, and recent repairs
  • Post-crash towing, storage, download, testing, cleaning, repair, salvage, and replaced parts
  • Whether damage resulted from the collision or existed before it

Investigate cargo and visibility

Document load weight, distribution, securement, custody, delivery sequence, rear visibility, mirrors, cameras, vehicle dimensions, and stopping or turning demands. A shifted load or obstructed view requires evidence showing when the condition arose and whether it affected the event.

Preserve electronic and operational records

  • Telematics, event or engine data, cameras, route and dispatch systems, mobile devices, and driver-assistance data
  • Electronic logs when applicable, time records, delivery scans, customer timestamps, messages, and calls
  • Fuel, toll, scale, parking, rental, lease, cargo, payment, and insurance records
  • Native formats, metadata, clock offsets, field definitions, audit history, and retention settings

Map insurance without treating it as fault

49 C.F.R. § 387.7 addresses financial responsibility for covered motor carriers. Applicability and required evidence depend on the operation and related provisions. Other commercial, rental, owner, driver, hired-auto, nonowned-auto, umbrella, and excess policies may also require review.

The related box-truck insurance guide explains how vehicle use, insured status, policy layers, and written positions can be charted separately from liability.

Connect evidence to the collision

Reconstruct speed, lane use, observation, following distance, braking, steering, turning, vehicle response, cargo, roadway, weather, and other traffic. A regulatory or maintenance issue matters only when the evidence connects it to an applicable duty and a causal mechanism.
