Class Code 7231: Trucking — Local Hauling and Cartage — CA Workers Comp Guide

What Class Code 7231 Covers

Class code 7231 applies to trucking and cartage operations defined by their local, short-radius nature. Covered operations include: dump truck operations hauling soil, aggregate, asphalt, and construction debris within a metropolitan area; flatbed and lowboy operators hauling equipment and materials to construction sites locally; ready-mix concrete trucks (when classified separately from the concrete plant); tank trucks hauling liquid materials locally; local freight carriers making deliveries within a metropolitan region; waste and recycling haulers operating within a defined service territory; and materials haulers for construction projects within a limited geographic area.

The defining characteristic is operational radius. “Local” in WCIRB classification terms typically means operations centered within a defined area — the truck leaves from and returns to a base within a metropolitan region, making multiple trips in a day rather than extended cross-state runs. The distinction from code 7219 (long-distance trucking) is both the geographic scope and the operational pattern.

Dump truck operations deserve particular attention because they are so common in California construction. Dump trucks hauling excavated soil from construction sites, aggregate for road base, asphalt for paving projects, and demolished concrete for recycling — all operated within the greater metropolitan area — are 7231 operations. Dump truck drivers working for grading contractors, paving contractors, and construction companies are typically coded 7231 regardless of which employer they work for, as long as their primary activity is local hauling.

7231 vs. 7219: Local vs. Long-Distance Distinction

Code 7219 applies to long-distance trucking operations — drivers making runs that extend beyond the local radius, including interstate runs and long-haul deliveries. The rate difference between 7231 ($4.42) and 7219 reflects the different exposure profile: long-distance drivers spend more time on highways at higher speeds, face fatigue risk from extended driving hours, and are away from home base for extended periods that complicate injury response.

For trucking companies with mixed local and long-distance operations, payroll must be split between drivers based on their actual route patterns. A driver who makes both local construction-site runs during the week and occasional long-haul runs requires payroll allocation based on actual time or trip records. Failure to maintain these records results in all payroll defaulting to the higher-rated code at audit.

Owner-operators present a special classification challenge in trucking. An owner-operator who is an independent contractor rather than an employee falls outside the employer’s workers comp policy — but California’s AB5 and subsequent legislation have significantly narrowed the independent contractor classification for trucking operations. Many owner-operators who believed they were independent contractors are now properly classified as employees under California law, requiring workers comp coverage by the motor carrier.

Who This Code Applies To

Local truck drivers are the core 7231 employees: dump truck drivers, flatbed drivers, materials haulers, and waste haulers operating within the local radius. Dispatchers and logistics coordinators who work in an office are coded 8810. Truck mechanics and yard workers at the trucking company who service and load vehicles may be coded to appropriate maintenance codes.

Construction companies that own their own dump trucks and employ drivers to haul materials for their projects code those drivers as 7231, separate from the construction trade codes used for their field crews. A grading contractor with 5 equipment operators and 3 dump truck drivers has both 1430 payroll (for operators) and 7231 payroll (for drivers) on their policy.

California’s Teamsters represent many local trucking employees. Union truck drivers typically receive higher wages (Teamster scale in Los Angeles and San Francisco Bay Area is among the highest in the country), which increases the payroll base against which the 7231 rate is applied. Working owners of small trucking operations who drive trucks themselves are coded 7231 unless they qualify for exclusion as corporate officers.

WCIRB Advisory Rate and Premium Calculation

At $4.42 per $100, local trucking generates moderate workers comp premium. For a dump truck company with 8 drivers averaging $72,000 annually (Teamster scale):

• Total driver payroll: $576,000
• Manual premium: ($576,000 ÷ 100) × $4.42 = $25,459
• With 1.05 ex-mod and 1.00 LCM: approximately $26,732
• Plus CA surcharges: approximately $27,677 total

For trucking companies, workers comp premium interacts with commercial auto insurance in important ways. Most serious injuries to truck drivers happen in motor vehicle accidents, which are covered by both workers comp (employer obligation for employee injury) and commercial auto (liability for third-party claims). Carriers underwriting workers comp for trucking operations always review the commercial auto loss history as part of their underwriting — a truck company with significant auto losses will face difficult workers comp placement regardless of the technical workers comp loss history.

Motor Vehicle Accident Risk: The Dominant Claim Driver

Motor vehicle accidents represent both the most frequent severe claim type and the primary driver of large losses in local trucking. A dump truck involved in a significant collision can produce workers comp claims for the driver ranging from minor to catastrophic depending on the accident severity. California’s urban highway systems — where local trucking operations are concentrated — produce significant crash frequencies.

Cal/OSHA requires employers to have an Injury and Illness Prevention Program (IIPP) that addresses motor vehicle safety for employees who drive as part of their work. For trucking companies, this means: driver qualification and licensing verification, pre-employment MVR checks, annual MVR monitoring, documented driver safety training, vehicle pre-trip inspection procedures, hours-of-service compliance for FMCSA-regulated drivers, and drug and alcohol testing programs.

Distracted driving has become an increasingly significant underwriting factor. Carriers ask about cell phone policies, telematics/GPS monitoring of drivers, and electronic logging device (ELD) use. Companies with telematics that demonstrate safe driving behavior — appropriate speed, smooth braking, minimal hard-cornering events — receive more favorable underwriting treatment.

Loading and Unloading Injury Risk

Beyond motor vehicle accidents, loading and unloading operations are a significant injury source for local trucking. Getting in and out of truck cabs (slip-and-fall from cab entry/exit), securing and unsecuring loads (hand and finger injuries from binders and straps), dump bed operations (struck-by from tailgate mechanisms), and manual material handling during delivery represent the non-driving injury pathways.

Dump truck operations have specific risks: hydraulic dump bed failures can cause unexpected bed lowering; operating a dump truck near overhead power lines during bed elevation creates electrocution risk; and driving with the dump bed elevated is a documented cause of bridge strikes and rollovers.

Carriers Active in Code 7231

Local trucking is written by most California carriers with construction and transportation appetite. ICW Group is active across all sizes. The Hartford and Travelers write trucking operations with clean MVR records. Liberty Mutual and Zurich compete for larger fleets. EMPLOYERS writes smaller trucking operations. Old Republic Specialty has dedicated transportation programs. For trucking companies with adverse auto or workers comp history, E&S markets through Markel and other specialty carriers provide coverage options. Teamsters-affiliated operations may access union trust funds for certain coverages.
