What force is driving light?

What force is driving light? None. Light is made of magnetic fields, electric fields and the energy that causes them to oscillate. We are taught that even if the source is turned of light keeps moving for ever Very unlikely. While light could potentially travel forever, obstacles along the way will stop or at least change the direction of light. It is said that that the light carries electromagnetic force. Incorrect. Light is a combination of magnetic fields and electric fields interacting with each other. That interaction is known as electromagnetism so light is known as an electromagnetic wave. Does this force drive the light or itself with light is driven by another force? Please make your questions clear before asking them.
