What discovery is most important in a TNC employer liability case?

Driver onboarding records, background check documentation, prior rider complaints tied to the specific driver, and the platform's internal safety policies are typically the most important discovery targets, since this evidence establishes what the company knew and when.

How do control factors affect a TNC liability case?

Control factors such as fare setting, route direction, rating systems, and deactivation authority help establish how much control a platform exercises over a driver, which supports arguments for both vicarious liability and direct negligence claims against the company.

Should referring attorneys name the platform or just the driver in a rideshare case?

In most cases, both should be evaluated for potential liability. Naming only the individual driver can leave significant recovery on the table if the platform's own screening or supervision failures contributed to the harm.

TNC Employer Liability California: Doctrine Behind Rideshare Injury Claims

TNC employer liability California doctrine sits at the intersection of employment law, agency law, and ordinary negligence. It has developed rapidly since ridesharing became a fixture of daily transportation, and attorneys handling these cases need a clear framework for evaluating when a platform, not just its driver, can be held responsible for a passenger's injuries. This page lays out the doctrinal landscape behind the firm's rideshare trial verdict and offers a practical roadmap for evaluating a similar referral.

The Independent Contractor Problem

Every major rideshare platform classifies its drivers as independent contractors rather than employees. That classification is the first obstacle in any TNC employer liability California analysis, because California's default respondeat superior rule imposes vicarious liability on employers for the negligent acts of employees within the scope of employment, but generally not for independent contractors. Plaintiffs' counsel cannot simply accept the label. California courts examine the substance of the relationship, asking how much control the hiring entity exercises over the manner and means of the work, not merely the end result.

Control Factors That Matter in a TNC Case

Several categories of evidence build the control record: fare setting, since the platform sets the price of every ride and drivers cannot negotiate; route direction, since in-app navigation frequently dictates the route; rating and deactivation systems, since platforms can deactivate an account for conduct they deem unacceptable; acceptance rate requirements that penalize drivers for declining rides; and background check and vetting representations the platform markets to riders. No factor alone resolves the question, but together they support both direct negligence claims (negligent hiring, retention, or supervision) and, in appropriate cases, vicarious liability theories.

Direct Negligence Theories Against the Platform

Negligent hiring and retention

If the platform's own screening process failed to catch a disqualifying driving or criminal history, that failure supports a direct negligence claim against the company itself.

Negligent supervision

Prior rider complaints about a specific driver, if ignored or inadequately investigated, can establish that the platform had notice of a problem and failed to act on it.

Negligent undertaking

Under Restatement (Second) of Torts section 324A, a company that voluntarily undertakes a safety function, such as background screening or in-app safety monitoring, can be liable if it performs that function negligently and a passenger is harmed as a result.

The AB 5 and Proposition 22 Backdrop

Assembly Bill 5 codified the ABC test for worker classification. California voters then passed Proposition 22, carving out an exception for app-based transportation and delivery companies. Proposition 22 changed the classification landscape, but it does not eliminate the common law negligence theories available to an injured third party such as a passenger, pedestrian, or another driver.

Frequently Asked Questions

What is TNC employer liability in California?

TNC employer liability California refers to the legal theories under which a transportation network company, such as Uber or Lyft, can be held responsible for harm caused by one of its drivers. This includes both vicarious liability theories and direct negligence theories based on the platform's own screening, supervision, and safety practices.

Does Proposition 22 prevent lawsuits against rideshare companies?

No. Proposition 22 addresses driver classification for employment purposes such as wages and benefits, but it does not eliminate a passenger's or third party's ability to bring a negligence claim against the platform for failures in screening, supervision, or safety systems.

Can a rideshare company be sued even if the driver is an independent contractor?

Yes. Independent contractor status affects vicarious liability analysis, but direct negligence claims against the platform for negligent hiring, retention, or supervision remain available regardless of how the driver is classified.
