If you wish to use a route that includes toll roads with a rideshare vehicle, you need to set this in the GO App for the fare to be recalculated.
Please refer to the following for how to set this.
Changing settings after requesting a taxi but before boarding
If you've already requested a taxi and it's on its way, you can adjust settings by scrolling down on the dispatch screen until you see "Ride Information."
From there, enable the "Use toll roads" setting.
Changing settings during your ride
If you're already in a car, you can change the settings through the GO App.
Tap the [Destination/Toll Road Settings] button on the bottom right of the map, then enable the "Use toll roads" setting.
