Uber does not have a hard "mileage" limit in 2026, but there is a time limit that effectively caps the distance. Most Uber trips are automatically ended by the app after 4 to 8 hours of continuous travel (depending on the region) for driver safety and to prevent fare fraud. While you could technically take an Uber for several hundred miles (e.g., from Los Angeles to San Francisco), the driver has the absolute right to decline any trip they feel is too long or doesn't offer a profitable "return" leg. For extremely long-distance requests, it is considered best practice to message the driver immediately after booking to ensure they are willing to make the trek. In some markets, "Uber Intercity" specifically caters to these long-distance routes with fixed pricing, but for a standard UberX, the "limit" is essentially the driver's stamina and the app's internal trip timer.
