While Uber doesn't limit the distance you can travel on a trip, trips may automatically end after 4 hours. When this is about to happen, the driver is notified by the partner app.
Please let drivers know if you're planning to travel a long distance. Many drivers need to make the return trip home after reaching your destination, and it's polite to give them a warning of a long trip.
If you'd like to continue after a trip automatically ends, please request a new ride. Since your previous driver is nearby, they may receive this new trip request.
