Uber on Wednesday introduced new features aimed at improving safety for both riders and drivers.

A feature called Ride Check leverages the GPS and other sensors in a driver's smartphone to detect possible crashes, Uber CEO Dara Khosrowshahi explained in a blog post. If it detects an accident, Uber will ask you to confirm that you were involved in a crash. If you say yes, the app will open Uber's new Safety Toolkit, which offers helpful features like a 911 button that lets you call emergency services with one tap.

"This technology can also flag trip irregularities beyond crashes that might, in some rare cases, indicate an increased safety risk," Khosrowshahi wrote. "For example, if there is a long, unexpected stop during a trip, both the rider and the driver will receive a Ride Check notification to ask if everything is OK."

To reduce the risk of accidents, Uber plans to start testing a feature that will let drivers interact with the app with just their voice. The feature will let drivers use voice commands to accept trips and communicate with customers, so they can keep their eyes on the road.

Meanwhile, Uber plans to beef up privacy by hiding specific pickup and drop-off addresses in a driver's trip history. "Going forward, after the trip ends, the Driver app will only show the general area where a trip started and ended, not the address," Khosrowshahi wrote.

Finally, Uber is planning to give riders the option to use two-step verification every time they log into their account. If you opt to enable it, you can choose to receive one-time verification codes via text or a third-party authenticator app like Google Authenticator, Authy, or Duo. Until now, Uber has only used two-step verification for suspicious login attempts and when users log in from a new device.
