First step, come up with 5 gags for Department of Motor Vehichles. This image was chosen to go further. It is a student driver and the cop/ teacher is not in the car because they have flown through the window into the tree. This will be easier to see and understand in the image in the next step.
Second step, view original cartoon gag in three different views. This is the one chosen to go further. A student driver obviously didn't slow down and hit the speed bump which caused the wreck into the opposite direction and the cop/teacher flew out of the car into the tree. The arrow that you can slightly see was a note to move the cropping of the gag.
My final cartoon gag after being scanned and taken into photoshop and colored there.
