What is the ruling on money taken by a government bus driver in exchange for transporting female students from their homes, knowing that he is ordered to stop at a specific location?

The driver is not permitted to violate the orders of the bus owner, nor is it lawful for him to take extra money. The female students should inform the officials of their need for the driver to reach their homes. If permission is granted, then all is well; otherwise, they must hire someone to transport them.
