The 50-hour rule: California AB5 explained

What AB5 actually is (and isn't)

California Assembly Bill 5, passed in 2019 and effective January 1, 2020, codified the 'ABC test' for determining whether a worker is an employee or an independent contractor. The default presumption under AB5 is that workers are employees unless the hiring entity can prove all three prongs of the ABC test: the worker is free from control, performs work outside the usual course of the hiring entity's business, and is customarily engaged in an independent trade.

For rideshare and delivery drivers, AB5 was supposed to reclassify everyone as employees. Then Proposition 22 — the 2020 ballot measure funded by $200 million from Uber, Lyft, DoorDash, and Instacart — carved out a specific exemption for app-based drivers, keeping them as independent contractors with some added benefits. The legal status of Prop 22 has been litigated ever since, but as of 2025 it remains in effect, and gig drivers in California operate under its framework.

This article is about the part of AB5 that almost no drivers understand correctly: the '50-hour rule.' It's not actually in AB5 itself. It's in the ABC test, and it determines when AB5 applies to a contractor even outside the Prop 22 gig exemption.

The ABC test and the 50-hour threshold

Here's the rule that matters. Under the ABC test (codified in California Labor Code 2775, which AB5 amended), a worker is presumed to be an employee unless the hiring entity proves all three prongs. Prong B — that the worker performs work 'outside the usual course of the hiring entity's business' — is where most contractors run aground.

For rideshare, this is muddled by Prop 22. But for the broader question of when an independent contractor crosses into employee territory, California courts and the EDD have used a working-hours threshold as a practical signal. The frequently cited '50-hour rule' isn't a statutory line — it's a guideline from Borello (1989) and subsequent cases suggesting that a contractor who works more than 50 hours per week for a single hiring entity is presumptively integrated into that business and likely fails prong B.

The 50-hour rule is not in AB5. It's a judicial guideline from case law interpreting the common-law employment test. Drivers repeat it as gospel; lawyers treat it as one signal among many.

What this means for a California gig driver today

For most rideshare and delivery drivers, the 50-hour threshold is academic because Prop 22 exempts you from AB5's ABC test entirely — as long as you're driving for an app-based platform that qualifies under Prop 22's specific criteria (engagement through an app, time-based or task-based work, etc.). Under Prop 22, you're an independent contractor regardless of hours, and you receive the limited Prop 22 benefit package (health subsidy, mileage-based earnings guarantee, etc.).

The 50-hour rule becomes relevant in two specific situations. First, if you drive for a non-app-based service — a traditional limo company, a private car service, a courier that dispatches by phone. Those businesses are not exempted by Prop 22, and if you drive 50+ hours/week for one, you're at significant risk of being reclassified as an employee (with back wages, payroll taxes, and penalties).

Second, the 50-hour threshold is increasingly cited in the broader misclassification litigation against gig companies. Plaintiff attorneys argue that any driver working 50+ hours is, by the Borello logic, functionally an employee regardless of the app's 'flexibility' rhetoric. Courts have not uniformly accepted this, but it's a recurring thread in the ongoing legal fights.

If you're a driver, here's what to actually do

Three practical takeaways. First, if you drive exclusively for Uber/Lyft/DoorDash via the apps, AB5's ABC test doesn't apply to you right now because of Prop 22. Don't lose sleep over the 50-hour rule in that context — but do understand that Prop 22's legal status could change (the California Supreme Court has pending cases), and a future without Prop 22 would put all California gig drivers back under AB5.

Second, if you drive for any non-app gig platform — limo, courier, private car — keep your weekly hours under 50 for any single client. If you're at 50+ for one company, you're at high risk of misclassification and the company is at high risk of an EDD audit. Either become an actual employee (which most don't want) or diversify across multiple clients so no single one captures 50+ hours.

Third, track your hours. The 50-hour rule is a 'guideline' but it's a guideline courts take seriously. If you ever end up in a misclassification dispute (either way — you want to be reclassified as an employee for back wages, or the company wants to defend your contractor status), your hours log is the central document. Drive without a paper trail and you're at the mercy of whatever the platform's records say.

What about the rest of us?

AB5 is California-specific. But the underlying ABC test is spreading. New Jersey, Massachusetts, Illinois, and New York have all considered or passed versions of the ABC test (with varying exemptions for gig work). The 50-hour rule, as a judicial signal of integration, will travel with the ABC test wherever it goes.

If you're outside California, the practical advice is the same: track your hours, diversify your clients if you want to remain a contractor, and watch your state's employment law. The federal DOL under the 2024 administration issued an ABC-test-style rule for FLSA purposes, which was withdrawn in 2025 — but state law is where the action is, and the trend is toward more contractor classification scrutiny, not less.

The bottom line

The '50-hour rule' is shorthand, not statute. It captures a real legal principle — that contractors who work full-time-equivalent hours for one client are presumptively employees under the ABC test — but it gets misapplied constantly in driver forums. For most app-based drivers in California, Prop 22 moots the question. For everyone else, the rule is a useful risk signal, not a hard line. Track your hours, know your state's law, and don't believe anyone who tells you the 50-hour rule is a bright line that automatically makes you an employee.
