Who was in charge of the chariot after Phaethon takes off?

After Phaethon takes off with the chariot of the sun, he loses control of the steeds that pull it. As a result of his reckless driving, the sun chariot causes chaos in the heavens and on Earth. Ultimately, Zeus intervenes by striking Phaethon down with a thunderbolt to prevent further disaster, restoring order to the skies. After this incident, the chariot is no longer under Phaethon's control, and the sun is guided by Apollo, its rightful driver.
