Absolutely! While your ride is in progress, tap the up arrow next to your driver's information and select “SPLIT FARE.” On the next screen select who you would like to split your fare with (we'll automatically display your phone's contacts) and confirm.
Everyone you select to split your fare with will receive a text message. All they need to do is open up the Uber app (or sign up if they haven't already) and confirm to split the fare.
Fares are split equally between riders, and there is a $0.25 fare split fee for each participant.
