Trucking Industry Classification Codes

Big Rig Truck Classification Codes And Descriptions

Trucking Industry Classification Codes in the USA

The trucking industry in the United States uses standardized classification codes to categorize operations for regulatory, insurance, and business purposes. These codes streamline communication across sectors and ensure compliance with federal and state laws.

Key Classification Systems

NAICS (North American Industry Classification System):
The NAICS code for General Freight Trucking is 4841, which splits into subcategories like Local (484110) and Long-Distance (484121 and 484122). Specialized Freight Trucking is coded under 4842, with variations for different types of hauling.
SIC (Standard Industrial Classification):
Though largely replaced by NAICS, SIC codes like 4213 (Trucking, Except Local) and 4212 (Local Trucking Without Storage) are still used in some legacy systems.
DOT and FMCSA Codes:
The Department of Transportation (DOT) and the Federal Motor Carrier Safety Administration (FMCSA) assign specific Motor Carrier (MC) and USDOT numbers to identify trucking operators and track compliance.
Insurance Classification Codes:
Insurers use proprietary codes derived from ISO standards to assess risks based on fleet size, cargo type, and routes.

Why Are Codes Important?

These codes influence licensing, tax classification, and eligibility for contracts and insurance. Properly classifying a trucking business ensures accurate risk assessment, competitive insurance rates, and legal compliance.

Understanding and using the correct codes is essential for trucking companies to optimize operations and maintain their standing in the highly regulated transportation industry.

Insurance companies classify trucking companies both small and large using different Standard Industry Classification Codes or (SIC’S) coding systems.
