What Is Class Code 5427 in Workers Compensation?
Class code 5427 is a standard workers compensation classification used for employees who drive motor trucks or tractors to haul cargo, load or unload freight, or operate vehicles with a gross vehicle weight rating above 10,000 pounds for hire or reward. This code sits within the National Council on Compensation Insurance (NCCI) system, which most states use to organize job risk levels into uniform categories. Every occupation gets a code, and each code carries a rate that reflects the historical injury frequency and severity for that type of work.

For a trucking or logistics employer, assigning the correct class code 5427 payroll is one of the most straightforward ways to ensure the premium reflects the actual exposure on the job. Misclassifying drivers as office workers or mixing them into a generic transportation category can trigger audits, premium adjustments, and unexpected costs at renewal.
Which Businesses and Workers Fall Under Class 5427?
The classification applies primarily to for-hire motor carriers and businesses that move goods by truck. Common roles that fall under class 5427 include:
- Heavy and tractor-trailer truck drivers hauling freight for compensation
- Delivery drivers operating trucks over 10,000 pounds GVWR
- Tanker and flatbed drivers
- Cargo haulers who load, secure, and transport goods
- Interstate and local route drivers paid on a per-trip or mileage basis
The critical test is whether the work is performed for hire or reward. An employee driving a company truck to deliver goods for a fee falls squarely into class 5427. A worker using a personal vehicle for occasional local deliveries may fall into a different classification, depending on the state and the nature of the arrangement.
How Class 5427 Affects Your Workers Compensation Premium
Every NCCI class code has a base rate that reflects the relative risk of that occupation. Class 5427 generally carries a higher base rate than office-based codes because driving for a living involves exposure to roadway accidents, loading injuries, and long hours behind the wheel. Your premium is calculated by multiplying the class rate by your payroll dollars assigned to that code, then dividing by 100.
When payroll is split across multiple class codes, the blended rate determines your final premium. If a significant portion of your payroll sits in class 5427, your overall workers comp cost will reflect that trucking exposure directly. Conversely, misclassifying driver payroll into a lower-risk code can result in a premium that looks attractive at quoting but gets corrected during audit, often with a surcharge.
Class 5427 vs. Related Transportation Codes
Understanding where class 5427 sits among other transportation codes helps clarify its scope:
| Class Code | Typical Activity | Risk Profile |
|---|---|---|
| 5427 | Motor truck cargo hauling for hire, vehicles over 10,000 lbs GVWR | Higher — roadway and loading hazards |
| 7310 | Drayage or short-distance hauling, often local | Moderate — shorter routes, different exposure |
| 7380 | Drivers operating vehicles 10,000 lbs or less GVWR | Lower — smaller vehicles, different risk |
| 7382 | Delivery drivers, vehicles 10,000 lbs or less | Moderate — frequent stops, pedestrian interaction |
| 8742 | Office clerical work in transportation or trucking firms | Lower — sedentary, administrative duties |
The distinctions matter because a single trucking company may carry payroll across several codes. A firm with drivers, dock workers, and office staff will typically have a blended rate shaped by each classification.
Payroll Classification and Common Errors
One of the most frequent errors with class code 5427 is misallocating payroll. If a company lists a driver who spends part of the day hauling freight and part of the day performing administrative tasks, the payroll must be split between class 5427 and the appropriate clerical code. Failing to do so can distort the experience modification factor over time.
Another common issue is the treatment of owner-operators and leased drivers. Whether these workers fall under class 5427 or a separate code depends on the contractual arrangement, the degree of control, and state-specific rules. Some jurisdictions treat leased drivers as the insured's employees for classification purposes, which pulls their payroll into the policy's class code structure.
Experience Mod and Long-Term Rate Impact
Class 5427 payroll feeds directly into the experience modification factor, or mod, which adjusts your premium based on your claims history relative to other employers in the same class. A clean claims record in class 5427 can produce a mod below 1.0, reducing your premium. A string of cargo-hauling or vehicle-related claims pushes the mod above 1.0, raising the cost for every dollar of payroll in that code.
Because class 5427 involves active roadway exposure, the claims that most often drive mod changes are vehicle accidents, loading and unloading injuries, and slips or falls at the dock. Targeted safety programs around pre-trip inspections, securement protocols, and dock safety can reduce the frequency of these incidents and, over time, lower the mod applied to your class 5427 payroll.
State Variations and Classification Nuances
While NCCI provides the underlying classification system, individual states retain the authority to adopt, modify, or create their own class codes. A handful of states have their own version of a motor cargo hauling code that behaves similarly to class 5427 but may carry a different rate structure or payroll allocation rule. Some states also distinguish between interstate and intrastate hauling, which can shift which code applies to the same driver depending on the route.
Because these variations directly affect your premium and audit outcomes, it is worth reviewing your policy with a broker or agent who understands the classification rules in your specific state. Confirming that class 5427 payroll is entered correctly at quoting and tracked accurately through the policy period is one of the simplest ways to avoid surprises at renewal.
