Chattanooga is a test market for new Uber emergency features.

The ridesharing company recently announced several features and an investment in safety, including a button that allows users to call 911 directly from the business’ app.

That feature shows the 911 operator the user’s real-time location with both a map and address.

An Uber spokeswoman said via email:

Federal regulators estimate about 10,000 lives could be saved every year if first responders were able to get to a 911 caller just one minute faster. We’re teaming up with RapidSOS to pilot 911 integration with local emergency authorities. If a rider uses Uber’s emergency button in Chattanooga, their location and trip details will be automatically sent to the 911 dispatcher.

Engadget has a video that breaks down some of the new features.
