Search “AB5 trucking” and a lot of what comes back was written while the outcome was still an open question: petitions pending, injunctions in place, everyone waiting on a ruling. That’s not where things stand anymore. Three separate courts have closed three separate challenges since 2022, on three different legal theories, and none of them went the trucking industry’s way. What’s actually unresolved in 2026 isn’t whether California’s AB5 reaches trucking. It’s which drivers, in which arrangements, a state investigator would actually flag. That question doesn’t have a one-word answer.
“I’m Leased On — Does AB5 Still Threaten Me?” What the Courts Have Already Decided
The legal fight over AB5 and California trucking ended years ago — three courts, three theories, one answer each time. What changed in 2025 is enforcement, and it isn’t landing on owner-operators running their own authority through a broker. Here’s what’s decided, what isn’t, and why the difference is fact-specific, not a checkbox.

What the courts actually decided, and when
The Ninth Circuit ruled first, on April 28, 2021, in California Trucking Association v. Bonta: AB5 is a generally applicable labor law, it doesn’t freeze in place a motor carrier’s prices, routes or services, and so it isn’t preempted by the federal law that normally shields interstate trucking from state regulation, the FAAAA. You can read the opinion itself via Justia’s case file. The trucking industry asked the Supreme Court to hear it anyway. On June 30, 2022, the Court declined (see the docket on SCOTUSblog). That is the date AB5’s ABC test became enforceable against California motor carriers for good, not on appeal, not under injunction.
The industry went back to court with a second challenge, this time arguing the Commerce Clause and Equal Protection Clause instead of preemption. On March 15, 2024, Judge Roger Benitez of the Southern District of California dismissed it, finding no protectionist purpose behind a law that, as one law firm summarizing the ruling put it, burdens in-state motor carriers as well as out-of-state motor carriers. He added that further complaints belonged on a “soap box” or at the “ballot box” rather than in his courtroom, language quoted in Benesch’s summary of the ruling. OOIDA appealed, and on May 16, 2025 the Ninth Circuit affirmed: AB5’s business-to-business exemption treats businesses differently from individual workers, the court held, and doesn’t discriminate between in-state and out-of-state drivers either. Reporting from Land Line Media has the detail. OOIDA’s president called the decision disappointing and said the group was weighing its options; no further petition in that case shows up in public court trackers as of this writing.
Three courts, three theories, one outcome each time. A 2026 article implying AB5’s legal status in trucking is still up in the air is describing 2021, not now.
What actually changed: enforcement showed up
For roughly two years after the ABC test became enforceable, industry counsel routinely described trucking enforcement of it as close to nonexistent: the law applied, but almost nobody was getting cited under it. That changed in October 2025. California’s Labor Commissioner cited Costco Wholesale, Ryder Last Mile, and a Chula Vista subcontractor called Mega Nice Trucking a combined $868,128, roughly $663,000 of it owed directly to 58 delivery drivers, for misclassifying them as independent contractors on last-mile delivery routes. The state’s Bureau of Field Enforcement had opened the investigation over a year earlier, in July 2024, after two former Mega Nice drivers complained about unpaid wages, per the Department of Industrial Relations’ announcement. All three companies have appealed, so the final dollar figure could still move; the fact pattern the state built the case on doesn’t depend on how the appeal comes out. A trade write-up in March 2026 described 2025 and 2026 together as “a significant escalation in regulatory enforcement,” pointing to that same case as the template other investigations are now following, in CityWatch LA’s rundown.
What made that particular arrangement a target is worth sitting with, because it isn’t “trucking” as a category. Mega Nice supplied drivers who ran Ryder Last Mile’s routes delivering Costco’s big-box freight, and the state found Costco and Ryder exercised both direct and indirect control over drivers who were, on paper, independent contractors. That’s a dedicated, single-client, schedule-controlled setup — almost the textbook shape of what the ABC test’s first two prongs (freedom from the hiring entity’s control, work outside its usual business) exist to catch. It is not the shape of a driver running his own authority and picking loads off different brokers.
The distinction that actually matters: whose worker is it?
AB5 doesn’t ask what a contract calls somebody. It asks a hiring entity to prove all three prongs of the ABC test, or fall back on whether the relationship fits one of the law’s carved-out exemptions. Trucking’s most relevant one is the business-to-business exemption that the Ninth Circuit’s May 2025 ruling was actually about. That exemption tends to hold up for a driver who runs his own MC authority, negotiates his own rate on each load, and works multiple brokers or carriers rather than one. It tends not to hold up for a driver whose day-to-day work looks like an employee’s, whatever the paperwork says: one company, a set schedule, loads assigned rather than chosen. A plain-language rundown of how the test and the exemption interact is at DAT’s overview of AB5 for carriers.
| What the arrangement looks like | Where AB5 risk tends to concentrate |
|---|---|
| Driver runs his own MC, takes brokered loads from several companies, sets his own rate | Low: looks like a business dealing with other businesses, not a worker inside one |
| Driver is leased on to one carrier’s authority under a real lease, still free to decline loads | Depends on how much control the carrier exercises in practice, not just on paper |
| Driver is “independent contractor” on paper but works one dedicated account, fixed schedule, assigned runs | High: close to the arrangement California just fined $868,128 over |
Notice what isn’t in that table: hauling into or through California on a brokered load. AB5 targets the relationship between a hiring entity and the person doing the work, not a state line a truck happens to cross. An owner-operator running his own authority who picks up a load in Ohio, drops it in Sacramento, and takes his next load from a different broker entirely hasn’t entered into the kind of relationship AB5 is built to reclassify. The freight isn’t restricted. The employment relationship, if there is one, is what gets tested.
Why this still isn’t a green light
None of the above is a bright line, and treating it as one would be the wrong way to read this piece. The ABC test and the business-to-business exemption both turn on facts: how much control a carrier actually exercises, how exclusive the relationship really is day to day, not what a contract’s cover page calls the driver. A lease-on agreement that reads as a real lease can still be run, in practice, like employment: a fixed schedule, no ability to decline loads, one company controlling every mile. That’s the fact pattern regulators look past the label to find, and it’s exactly why the Costco/Ryder/Mega Nice case turned on how the work actually functioned, not on what the drivers were called. Nothing here is legal advice, and nobody should read a specific lease-on agreement as “AB5-safe” off the back of a blog post. A carrier or driver with a real question about a specific arrangement should put it in front of an attorney who handles California employment and transportation law, not a search result.
What’s worth actually checking
- Whose authority is on the paperwork for this specific arrangement: your own MC, or a carrier’s you’re leased to. The two carry different exposure, and it’s worth knowing which one you’re in.
- Whether you can actually decline a load and work another broker or carrier. Not whether the contract says you can. Whether it happens in practice, without consequence.
- Whether a lease-on agreement reads like a real lease or a disguised schedule. The same clauses our piece on lease agreement red flags walks through are exactly what a regulator would look at too.
- Whether the agreement says anything about who answers for a misclassification claim. Most don’t, and finding that out after a complaint is filed is late.
- Whether you’re checking back periodically, not just once. This file has changed direction on a roughly annual cycle since 2021, and enforcement patterns in particular are still forming.
The legal fight over whether AB5 applies to California trucking is finished, decided three times over by three different courts on three different theories. What’s still being worked out is enforcement, and so far it’s landing hardest on dedicated, single-client arrangements dressed up as independent contracting — not on an owner-operator running his own authority through a broker. That’s a meaningful difference, but it’s a fact-specific one, not a form to fill out. If you’re weighing a lease-on placement against running your own authority with dispatch behind you, or you just want someone who’s read the actual rulings to talk through what you’re looking at, see how Fortuna works or talk to a dispatcher.
