What is respondeat superior?
Respondeat superior is Latin for "let the master answer." It is the rule that an employer is legally responsible for the careless acts of its employees when they happen within the scope of the job, such as a delivery driver crashing while on a route.

Respondeat superior example: the delivery van and the detour
Example: a furniture company's driver runs a red light in El Paso while delivering a couch and hits your car. Your hospital bills, therapy and lost work come to $75,000. The driver's own auto policy, if any, may be small. The company's commercial coverage is usually much larger.
If the driver was on the delivery route, the claim against the company is strong under respondeat superior, because the crash happened within the scope of the job. Now change one fact: the driver had clocked out and was using the van to help a cousin move on a Sunday. The company may argue the driver left the scope of employment, and the claim against it gets much harder. That single question can decide whether there is enough insurance to cover $75,000.
How does respondeat superior work in Texas and Arizona?
| State | What we verified |
|---|---|
| Texas | Injured people commonly allege the driver was in the course and scope of employment to hold the company liable. In commercial-vehicle cases, if the employer stipulates that the driver was its employee acting within the scope of employment, its liability for ordinary negligence is based only on respondeat superior. |
| Arizona | A party is responsible for the fault of another person who was acting as its agent or servant. |
The Texas stipulation rule mainly changes how a trucking trial is organized and which separate claims against the company go forward. It does not erase the company's responsibility for its driver.
Why does respondeat superior matter after a work-vehicle crash?
It decides whose insurance pays. Look for logos on the vehicle, uniforms, delivery apps open on the driver's phone, and anything said at the scene about being on a job. Put those details in your notes and photos before they fade. Independent contractors, rideshare drivers and app-based couriers raise harder scope questions, and companies often contest them.
Respondeat superior vs. negligent hiring
Respondeat superior makes the employer answer for the employee's mistake, even if the company did nothing wrong itself. Negligent hiring or supervision is a claim about the company's own mistake, such as putting a driver with several crashes behind the wheel.
Questions
What does "scope of employment" mean?
Doing the job or something reasonably connected to it. Courts look at what the worker was doing, when and why.
Does respondeat superior cover independent contractors?
Usually not in the same way, though a business can still answer for an agent or servant in Arizona. Labels on a contract do not always decide it.
Do I still name the driver?
Often yes. Naming both the driver and the employer is common.
