Look at the picture and try to guess the meaning of hit the road idiom. Hmmm, it's not so easy to understand is it? But the photo can help you to remember it.
Hit the road: to leave (especially to go home); to depart on a journey (especially to travel to a place by car).
The guy in the photo is hitting (banging) a sledge hammer into the road. He's making a big hole in the road. That's a literal meaning of the idiom. But that's not what we're doing here. Instead, we're talking figuratively. What's really hitting (landing) on the road is our feet or the tires of our car.
The "hit" part is simply a way of saying that we are making a definite departure. It's a way to emphasize you're leaving a place or traveling somewhere. Again, because we say hit the "road" it's frequently used to describe travel by car (especially travel that takes several hours = a road trip).
