Don't allow yourself to become distracted by talking on your cell phone, shaving, eating, drinking, putting on makeup, or reading the newspaper. Distractions lead to mistakes, and mistakes lead to hostility. Music can calm your nerves and help you to enjoy your time in the car. If you have a CD or tape player, treat yourself to some new tapes and allow yourself to listen to them only in the car. This is when drivers start out well spaced but end up at the same place at the same time, bringing traffic to a standstill.
Traffic flows best when everyone is travelling at about the same rate.
Drive the posted speed limit. The shortest distance between two points may not always be a straight line. Try mapping out an alternate route. Even if it looks longer on paper, you may find it is less congested. However, if you have chosen the road less travelled, don't turn it into a racetrack by speeding.
