Starting July 17, Uber will let drivers accept tips .
To celebrate, the rideshare company is matching every tip given by riders to drivers on July 18.
Riders can tip their drivers up to 2 times the total fare of their trip, capped at $100. The service is optional, and tipping does not affect rider ratings. Drivers have to rate their rider first before they can see the receipt.
As a rider, you have up to 7 days after the trip to rate the driver and add a tip. If you rate your driver without tipping, you can go back and add a tip up to 30 days later.
Tipping is available on both Uber rides and UberEATS.
