Driving while irritated, upset or shaken will substantially alter one's judgment behind the wheel. An angry driver is an aggressive, offensive and highly dangerous driver. Stressful conditions involving personal or business life should be recognized as negative influences on driving habits. The driver should evaluate his or her state of mind before attempting the operation of a motor vehicle and should not drive when experiencing heightened stress, anger or fatigue.
1. The operation of a motor vehicle takes a clear and focused mind, uncluttered by thoughts of aggravation and distress. The driver with a wandering mind has a decreased awareness of the road, a slower reaction time, and an overall lack of safe driving habits. This driver is more likely to exceed speed limits, make unsafe lane changes and take greater chances on the road. The ability to anticipate and determine upcoming driving hazards and conditions is also adversely affected.
2 Do we need stress in our life? Yes, you need stress in your life! Does that surprise you? Perhaps, but without stress, life would be dull and unexciting. Stress adds flavor, challenge, and opportunity to life. Too much stress, however, can seriously affect your physical and mental well-being.
3 A major challenge in this stress filled world of today is to make the stress in your life work for you instead of against you. Do you need stress in your life?

It is clear that if the driver is experiencing heightened stress, anger or fatigue should not drive because he/she will lose his/her temper and be more likely to have an accident on the road and more of he/she is with a group of people in the car. As drivers, we should be able to have a lot of patience and coordination on the road and if you are under stress, you are not going to focus and may cause a terrible car accident. So, just be careful in the road, be attentive all the time, use your headlights, respect the traffic signs and be calm while driving. Good luck!
