Culture can be defined as behavior that is learned and transmitted to members of a group. A child learns a particular behavior through observation as well as through positive and negative feedback from his/her family and peers. A minor point to remember is that this feedback can be overt or covert. Much covert feedback involves nonverbal cues that an outsider to that culture would not understand.

Many drivers do little more than look over the hood while driving. You must train yourself to fix your eyes so that they can see not only the road ahead of you but objects on each side of you and behind you. Concentration is one of the most important elements in safe driving. The driver’s seat is no place for window-shopping, nor it is a place for a tired driver or worried one. Driving an automobile is a full-time job.
