You can request that your driver make multiple stops when requesting a ride. Here's how:
1. Open the Uber app and tap the "Where To?" box
2. Tap "+ Add multiple stops" to add up to 2 additional stops
3. Tap "DONE" to continue
Stops will be made in the order they're added. To remove a stop, tap the "X" next to it.
Remember to keep each stop under 3 minutes. If you're splitting your fare, it will be split for the entire ride, not split by the cost to each stop.
NOTE: This feature is not available on UberPOOL rides.
