AB5 and Independent Contractor Status: What Every Owner-Operator Should Know

What Is AB5 and Why Does It Matter for Trucking?

California Assembly Bill 5 (AB5), signed into law in September 2019 and effective January 2020, codified a strict test for determining whether a worker is an employee or an independent contractor. Its application to the trucking industry has created one of the most significant legal and operational challenges facing owner-operators and motor carriers in decades.

AB5 codified the 'ABC test' established by the California Supreme Court in its 2018 Dynamex decision. Under the ABC test, a worker is presumed to be an employee unless the hiring entity can demonstrate all three of the following: (A) the worker is free from the control and direction of the hiring entity in the performance of the work, (B) the worker performs work outside the usual course of the hiring entity's business, and (C) the worker is customarily engaged in an independently established trade, occupation, or business of the same nature as the work performed.

The critical element for trucking is Prong B. A trucking company's usual course of business is transporting freight. An owner-operator who hauls freight for that trucking company is performing work within the trucking company's usual course of business. Under a strict application of Prong B, virtually every owner-operator leased to or contracted by a motor carrier fails the ABC test and would be classified as an employee.

This reclassification has enormous financial and operational implications. If owner-operators are employees, carriers must provide workers' compensation insurance, unemployment insurance, health benefits, pay employment taxes (Social Security, Medicare, state UI), guarantee minimum wage for all hours worked, and comply with California meal and rest break requirements. The cost increase for carriers is estimated at 20-30% per driver.

For owner-operators, employee classification means losing their independent business — their authority, their truck ownership benefits, their ability to negotiate rates, their tax deductions for business expenses, and their entrepreneurial identity. Many owner-operators chose independent operation specifically because they value the autonomy and business ownership that comes with it.

The trucking industry's response was immediate and intense. The California Trucking Association (CTA) filed a lawsuit in late 2018 seeking to block AB5's application to trucking, arguing that it was preempted by the Federal Aviation Administration Authorization Act (FAAAA), which prohibits states from enacting laws 'related to a price, route, or service of any motor carrier.'

The Legal Battles: Where Things Stand in 2026

The legal fight over AB5's application to trucking has been a multi-year saga that has reached the Supreme Court and is still not fully resolved.

The California Trucking Association obtained a preliminary injunction in January 2020 blocking AB5's enforcement against trucking companies, based on the FAAAA preemption argument. The Ninth Circuit Court of Appeals reversed this injunction in April 2021, ruling that AB5 was a generally applicable labor law not specifically targeting the trucking industry and therefore was not preempted by the FAAAA.

The CTA petitioned the Supreme Court for review, and in June 2022, the Court declined to hear the case (denied certiorari), effectively allowing AB5 to take effect in trucking. However, the Court's decision was based on procedural grounds — the CTA had brought a facial challenge arguing AB5 was preempted in all applications, and the Court indicated that as-applied challenges (arguing AB5 is preempted in specific trucking contexts) might have more merit.

Multiple as-applied challenges are now working through the courts. The most significant involves individual owner-operators and small carriers arguing that their specific business arrangements meet the traditional common-law independent contractor test (the Borello test that was used before AB5) and that AB5's more restrictive ABC test, as applied to their specific circumstances, is preempted by the FAAAA because it effectively dictates the price and service structure of their motor carrier operations.

In parallel, a separate legal theory has emerged through the 2024 Supreme Court decision in a non-trucking case. The Court held that federal preemption under similar aviation deregulation language prevents states from imposing classification tests that effectively prevent certain business arrangements. Several trucking-specific cases citing this precedent are working through federal courts.

Meanwhile, enforcement in California has been inconsistent. The California Labor Commissioner's office has investigated some trucking companies and issued citations reclassifying owner-operators as employees. Several class-action lawsuits filed by former owner-operators seek back wages, benefits, and reimbursement for business expenses they incurred while classified as independent contractors. Settlements in these cases have reached eight figures.

The practical reality in early 2026: AB5 is technically enforceable in California, but legal uncertainty persists. Many carriers have restructured their California operations to avoid using owner-operators in the state, while others continue to use owner-operators and accept the legal risk. The situation is unlikely to be fully resolved before 2028-2030.

How AB5 Has Actually Affected California Trucking

Beyond the legal theories, AB5 has had tangible effects on how trucking operates in California — and these effects offer a preview of what might happen if similar laws spread to other states.

Several large carriers have stopped using owner-operators in California entirely. Landstar, one of the largest carriers built on the independent contractor model, reduced its California owner-operator base significantly. XPO (now RXO) converted many California-based independent contractors to employee drivers. These conversions have increased carrier operating costs in California by an estimated 15-25% per truck.

Port drayage at the ports of Los Angeles and Long Beach has been disproportionately affected. The port drayage sector traditionally relied heavily on independent owner-operators, many of whom leased trucks from the motor carriers they contracted with. AB5 effectively outlawed this arrangement. Several drayage companies have converted to all-employee fleets, while others have ceased California operations. The disruption contributed to the port congestion problems during the 2021-2022 supply chain crisis.

Some owner-operators have restructured their businesses to attempt AB5 compliance. The most common approach is to operate under their own motor carrier authority (MC number) rather than leasing onto another carrier. An owner-operator with their own authority who contracts directly with brokers and shippers may have a stronger argument for independent contractor status under Prong B, because they are operating their own trucking business rather than performing work within another carrier's business.

However, operating under your own authority comes with significant costs and complexity: your own liability insurance ($12,000-$18,000+ annually), your own cargo insurance, FMCSA compliance obligations, UCR registration, IFTA reporting, and the administrative burden of running a one-truck business. Not every owner-operator can afford or wants to manage these requirements.

The impact on California freight rates has been meaningful. Shippers report that trucking costs for California origin and destination freight have increased 10-20% relative to comparable non-California lanes. Some of this increase reflects the higher labor costs of employee drivers; some reflects the reduced carrier capacity available in California as owner-operators and their carriers have exited the state.

Driver incomes in California have not clearly improved despite the reclassification. While employee drivers gain access to benefits and wage protections, their per-mile or per-load compensation has often decreased from what they earned as independent contractors. The net effect depends on the specific arrangement, but several surveys indicate that former owner-operators now classified as employees report lower take-home pay after accounting for lost tax deductions.

Which Other States Are Considering Similar Laws?

California was the first but is unlikely to be the last state to adopt strict worker classification rules affecting trucking. Several states have enacted or are considering similar legislation, and the federal government has also weighed in.

New Jersey adopted an ABC test for worker classification that closely mirrors California's AB5, effective through amendments to its unemployment and wage-and-hour laws. New Jersey's law applies across all industries, including trucking. Enforcement has been active — the state has assessed millions in penalties against companies using independent contractors who do not meet the ABC test.

Massachusetts has had an ABC test since 2004, predating California's law. The Massachusetts test is essentially identical to AB5's ABC test and has been enforced in the trucking context. Several Massachusetts trucking companies have been found in violation and ordered to reclassify drivers as employees.

Illinois, Connecticut, and Vermont have enacted worker classification laws that incorporate elements of the ABC test, though implementation details vary. Illinois's law applies primarily to construction but has been cited in trucking enforcement actions. Connecticut's law explicitly applies to transportation.

New York has been the most actively debated battleground. Multiple bills modeled on AB5 have been introduced in the New York legislature. Given New York's enormous freight market (the Port of New York/New Jersey is the largest on the East Coast), adoption of an ABC test in New York would have significant national impact. As of early 2026, no comprehensive bill has passed, but the issue remains on the legislative agenda.

At the federal level, the Biden administration's Department of Labor finalized a rule in 2024 revising the federal test for independent contractor status under the Fair Labor Standards Act (FLSA). The new federal test uses a totality-of-the-circumstances approach (not the ABC test) and is more nuanced than AB5 but still trends toward finding employee status in many trucking arrangements. The rule has been challenged in court but remains in effect.

The overall trend is clearly toward stricter worker classification enforcement. Owner-operators should prepare for a future where maintaining independent contractor status requires demonstrating genuine economic independence — your own authority, your own insurance, multiple customers, control over your rates and schedule, and a business that exists independently of any single carrier relationship.

How to Protect Your Independent Contractor Status

If you operate as an owner-operator and want to maintain your independent contractor status, proactive steps can strengthen your legal position regardless of which state's laws apply.

Operate under your own MC authority. This is the single most important step for establishing genuine independence. An owner-operator with their own authority contracts with brokers and shippers as a business-to-business transaction, not as a worker performing services for a hiring entity. The cost of maintaining your own authority ($5,000-$15,000 annually for insurance, fees, and compliance) is the price of genuine independence.

Maintain multiple customers. If 90% of your revenue comes from a single carrier or broker, the economic dependence suggests an employment relationship regardless of what your contract says. Aim to have no single customer represent more than 40-50% of your revenue. This diversification also reduces business risk.

Control your own schedule and routes. Accept or decline loads based on your own business judgment. Set your own rates — negotiate rather than accepting assigned work at predetermined rates. Choose your own routes. If a carrier dictates when you work, where you go, and what you earn with no meaningful room for negotiation, the relationship looks like employment.

Own or lease your equipment independently. If you lease your truck from the carrier you haul for, the arrangement looks like a cost-shifting scheme rather than a genuine business relationship. Own your truck outright, finance it through your own lender, or lease it from a third party unrelated to the carriers you contract with.

Maintain separate business infrastructure. Have your own business bank account, business insurance, business phone number, and business address. File taxes as a business (Schedule C or as an LLC/S-Corp). These are markers of a genuine independent business that strengthen your classification argument.

Keep records that demonstrate your independence. Document instances where you declined loads, negotiated rates, chose alternative routes, or served multiple customers in the same period. If your classification is ever challenged, contemporaneous evidence of business independence is far more persuasive than retroactive arguments.

Understand that no strategy is bulletproof. In states with the ABC test (California, New Jersey, Massachusetts), even genuinely independent owner-operators may face classification challenges under Prong B if they haul freight for motor carriers. The legal landscape is evolving, and the safest position is to maximize every indicator of independence while monitoring regulatory developments in your operating states.

The Future of Owner-Operator Independence

The independent owner-operator model, which has been a cornerstone of American trucking since deregulation in 1980, faces its most significant existential threat from the worker classification movement. However, the model is unlikely to disappear — it will evolve.

The most likely outcome is a bifurcation of the owner-operator market. Operators who maintain genuine independence — their own authority, multiple customers, their own equipment, meaningful rate negotiation — will continue to be recognized as independent contractors. Operators who are functionally employees — leasing trucks from the carrier they work for, running exclusively assigned loads, with no meaningful control over rates or schedules — will increasingly be reclassified.

This bifurcation is not necessarily bad for the trucking industry. The arrangements most vulnerable to reclassification are often those where the 'independent contractor' label is used to shift costs (insurance, equipment, fuel) from the carrier to the driver without providing genuine entrepreneurial opportunity. Eliminating these arrangements may improve conditions for the drivers affected, even if it disrupts the carriers' business models.

Technology may create new pathways for genuine independence. Digital freight platforms (DAT, Truckstop, Uber Freight, Amazon Relay, Convoy/Flexport) make it increasingly feasible for single-truck operators to find and book their own freight without depending on a single carrier relationship. As these platforms mature, they strengthen the case that an owner-operator using multiple platforms to run their own business is genuinely independent.

The FAAAA preemption question will ultimately be decided by the Supreme Court — it is a matter of when, not if. If the Court rules that FAAAA preempts state ABC tests as applied to trucking, the immediate AB5 threat to owner-operators would be eliminated, though federal classification standards would still apply. If the Court rules against preemption, AB5-style laws will likely spread quickly to additional states.

For owner-operators evaluating their future, the strategic imperative is clear: build a genuinely independent business. If you would not survive the loss of any single customer, if you do not control your rates and schedule, if you do not own your own equipment free of carrier entanglement — your 'independence' is vulnerable regardless of what your contract says. The operators who invest in genuine independence will thrive. Those who depend on the label without the substance will face increasing legal and financial risk.
