Truck Type Identifier
Types of commercial trucks differ in which federal regulations apply, which companies are involved, and which records exist. Match the vehicle by its features, then see the topics an investigation examines for that type.

Tanker
Identifying Features
- A rounded cylindrical tank instead of a box trailer
- Hatches on top and valves or hoses at the rear

Concrete Mixer
Identifying Features
- A rotating drum mounted behind the cab
- A very high center of gravity when loaded

Unidentified Vehicles
A vehicle that fits none of the twelve types above, or one nobody saw clearly, can still be identified from markings and records.
Weight decides which rules reach a vehicle. Federal trucking rules start at 10,001 pounds for a vehicle used across state lines, and a truck rated or loaded at 26,001 pounds or more needs a driver with a commercial license.
Unlisted Vehicle
Identifying Features
- Not every commercial vehicle fits a common silhouette
- Emergency, utility, and specialty vehicles have their own body designs
- The name on the door and the accident report are better starting points than the shape
Examination Topics
- Photograph the vehicle and any company markings if it is safe to do so
- The accident report is a starting point for identifying the vehicle and the carrier
- Records can identify the vehicle even when you cannot
Unknown Vehicle Type
Identifying Features
- A clear look is hard to get when an accident happens fast
- A color, a logo, or a trailer shape may be enough to start
- Witnesses and camera footage may fill in the rest
Examination Topics
- The accident report identifies involved vehicles
- Nearby cameras may have captured the vehicle
- Carriers can be identified from USDOT markings and shipping records
