Uber is building on its efforts to make passengers feel safer in their on-demand taxis, introducing continuous background checks for its drivers. Beginning in the US, Uber will now get alerts very soon after one of its drivers gets charged with a criminal offense.

Axios reports that Uber is going to rely on third-party services Checkr and Appriss to monitor its drivers. Up until now, once a driver has passed the initial background check and been approved, it hasn't always been easy for Uber to keep track of what happens after that point.
