Pre-fixed fare is a fare that is calculated based on the distance of the route from the pickup location to the destination, and is determined before the ride.
A pickup fee will be charged in addition to the pre-fixed fare.
Also, please note that a separate toll road fee will be charged if you choose a route via a toll road.
*If the customer does not show up at the specified location after a certain amount of time, the pre-fixed fare may be cancelled and the fare may be switched to a meter fare.
*GO App charge may apply in addition to the pickup fee depending on the area.
