Vehicle identification
What should I know about which truck hit you: tractor, trailer, box truck, dump truck or tanker?
Identify the power unit, trailer, body type, VIN, plates and company markings because different truck configurations leave different records.
Quick answer
Identify the power unit and anything attached to it separately. A tractor may pull another company's trailer. A straight or box truck carries its body on one frame. A dump truck, tanker, flatbed, tow truck, bus or delivery van may have different equipment and cargo records. Photograph the VIN plate only when safely accessible, plus plates, unit numbers, trailer numbers and all company markings.

01
Separate the tractor from the trailer
The tractor supplies power and carries the driver's cab. The trailer carries cargo and may have its own owner, plate and number. Photograph both sides and rear of each unit. For a straight truck, record the body type and any equipment such as a lift gate, mixer drum, boom, refuse body, tow apparatus or refrigeration unit.

The vehicle type points to records
A tractor-trailer may have ELD, dispatch, bill of lading and trailer inspection records. A dump or mixer may have job tickets and load weights. A tanker may have commodity and hazmat records. A delivery vehicle may have route scans and app data. The body type does not decide responsibility, but it identifies systems and record holders worth naming.
- Electronic logs and dispatch
- Cargo, weight, route or delivery records
- Inspection, maintenance and onboard system records

Questions
Short answers that stand on their own
Can the tractor and trailer have different owners?
Yes. Save the identifiers from both units and do not assume one logo identifies every company involved.
Can a VIN decoder decide who owned the truck on the crash date?
No. It decodes vehicle characteristics. Ownership and operation require registration, carrier and transaction records.
A quick reality check
What this page can and cannot tell you
This page cannot decide how the crash happened, who was at fault, whether a carrier controlled the trip, whether a particular record exists, insurance coverage, case value or a legal deadline. Public carrier data and vehicle categories are starting points for finding records; they do not establish responsibility or legal eligibility. A licensed attorney must review the complete facts and current law.
