As per Oxford dictionary, the definition of pull over is the following:
(of a vehicle) move to the side of or off the road.
Joy decided to pull over on to the hard shoulder.
I am not clear about the meaning of above sentence. Does it mean that Joy was lying on a bed in the supine posture, then he decided to turn to the side of the hard shoulder, in order to take side sleep posture? Otherwise, how can one move to the side of the hard shoulder?
I want to understand whether this sentence has quite a different meaning from what I understood.
