A missed appointment after a truck crash may result from hospitalization, transportation, work, caregiving, referral delay, cost, insurance authorization, scheduling, or improvement. The reason should be documented at the time rather than reconstructed later from memory. A missed-treatment entry should identify the appointment, recommended purpose, actual reason, notice given, rescheduling effort, condition during the interval, […]
When a passenger vehicle strikes the rear of a trailer, the condition and geometry of the rear-impact guard may become part of the investigation. The analysis is vehicle-specific. Trailer type, gross vehicle weight rating, manufacture date, rear structure, guard design, installation, maintenance, loading, ride height, impact location, approach angle, and the passenger vehicle all matter.
A rear-impact guard investigation must identify the trailer, manufacture date, vehicle configuration, applicable standard, guard design and installation, maintenance, pre-impact condition, collision geometry, and post-impact deformation before drawing a compliance or causation conclusion.
Preserve the trailer and striking vehicle
- Trailer VIN, certification label, make, model, manufacture date, GVWR, axle and suspension configuration, ride height, cargo, and load condition
- Guard manufacturer, label, part or model, manufacture date, installation instructions, attachment hardware, welds, bolts, supports, reinforcements, and prior modifications
- Undisturbed photographs, video, scans, measurements, paint transfer, deformation, fracture surfaces, corrosion, repair evidence, and removed components
- Passenger-vehicle dimensions, ride height, front structure, restraint and air-bag records, event data, crush, intrusion, contact pattern, and occupant positions
- Road grade, lane, lighting, visibility, marks, debris, final positions, tow and storage history, and every inspection or test
Determine the operating requirement that applies
49 C.F.R. § 393.86 addresses rear-impact guards and rear-end protection for vehicles in operation. Its requirements vary with vehicle type and manufacture date and include stated exceptions. For trailers and semitrailers at or above the stated rating manufactured on or after January 26, 1998, the section refers to the versions of Federal Motor Vehicle Safety Standards 223 and 224 in effect when the vehicle was manufactured.
Do not apply a current dimension or a rule for one vehicle category to a different trailer without checking the definitions, manufacture date, historical rule text, certification, configuration, and exceptions. A low rear structure can qualify under an applicable provision for reasons that should be documented rather than assumed.
Separate the guard standard from the installed-trailer standard
FMVSS 223 at 49 C.F.R. § 571.223 specifies requirements for rear-impact guards, including configuration, strength and energy-absorption testing, labeling, attachment hardware, and installation instructions. The exact historical version tied to manufacture may differ from today’s text.
FMVSS 224 at 49 C.F.R. § 571.224 addresses installation of rear-impact guards on covered trailers and semitrailers, including application, definitions, configuration, and attachment. Compliance records, certification, design drawings, instructions, manufacturing records, recalls, and later repairs should be connected to the actual trailer and guard.
Build the pre-impact condition history
- Purchase, ownership, lease, interchange, assignment, inspection, preventive-maintenance, and repair records
- Driver reports, roadside inspections, annual inspections, photographs, damage reports, collision history, corrosion, welding, replacement, and return-to-service decisions
- Manufacturer and repair instructions, parts invoices, technician identity, measurements, quality checks, and approvals
- Cargo weight and distribution, suspension setting, tire pressure, landing gear, trailer attitude, and ground conditions near impact
- Any evidence that the guard was damaged or altered by the subject impact rather than before it
Test compliance and causation separately
A missing, damaged, high, narrow, corroded, or deformed guard may raise questions, but a visual impression does not establish which requirement applied or whether a different condition would have changed intrusion, restraint loading, injury mechanism, or outcome. The analysis may require qualified vehicle, structural, reconstruction, biomechanical, and medical opinions based on preserved evidence and validated methods.
The related truck maintenance and inspection record guide explains how to connect the precise vehicle, component, notice, work, custodian, and collision mechanism.
Create a guard-evidence matrix
- Requirement and historical version; vehicle facts that make it applicable or inapplicable
- Design or certification record; installed configuration; measured post-crash condition
- Pre-impact maintenance or damage evidence; collision-caused change; unresolved alternative
- Contact geometry, energy path, intrusion, occupant evidence, and supported injury mechanism
- Opinion, underlying data, method, uncertainty, contrary evidence, and item still requiring inspection

How to Document Occupant Movement After a Truck Crash
An occupant may move forward, sideways, upward, rotate, or experience more than one movement during a truck collision. The useful record does not try to diagnose an injury from a photograph. It preserves what can be observed and allows qualified medical professionals and other appropriate reviewers to address causation. The file should connect the collision […]

Responsibility after a multi-vehicle truck crash cannot be evaluated reliably from the final vehicle positions alone. One event may involve an initial lane change, a later rear impact, cargo movement, evasive action, or a separate failure to slow. The useful question is not simply who struck whom last, but what happened at each stage and […]
Returning to Work After a North Carolina Truck Crash: A Documentation Guide
Returning to work after a truck collision is not a single yes-or-no decision. Driving, lifting, climbing, prolonged sitting, screen work, concentration, medication effects, sleep disruption, and travel may recover at different rates. The useful question is which duties can be performed now, under what restrictions, and when the plan will be reviewed again. A return-to-work […]
