3 Many of your decisions made while driving are based on what you SEE.  Visual Acuity o Ability to see objects both near and far. 20/20 vision is normal  Field of Vision o Area you can see directly in front of you, to both sides, and straight ahead

4  Field of Vision o Central Vision The area in front of you where everything is clear Only about 3 degrees wide o Peripheral Vision Unfocused areas to the sides of your central vision 180 degrees Peripheral vision is reduced 25% at 30mph and almost 90% at 60mph

5  Depth Perception o Ability to judge the distance between two objects i.e., following distance, stopping, ?  Color Vision o Ability to see color i.e., signs & signals Color blindness Inability to differentiate between certain colors Can still drive, but uses other visual cues

6 ProsCons More experienced Better at detecting potential hazards Decreased reaction time Poor eyesight Poor hearing  Older drivers may reduce their speed and try to avoid situations that require quicker reflexes

7  Determined by how quickly and efficiently you muscular and nervous systems can work together. o Hand & Foot Coordination i.e., steering, braking, accelerating, shifting gears  Some people are naturally more coordinated than others, but with practice can develop good driving skills. o Increase space cushioning and following distance

8  Hearing can tell us lots of things while driving o Your ears detect sounds of potential hazards Horns Sirens Vehicles you cannot see Pedestrians o Other instances  Information obtained from hearing can be crucial in split second decisions

12  What can you do? o Pull over o Rest areas o Eat lightly

13  Avoid driving at all costs o Illness makes you drowsy and/or inattentive o Injury can affect your ability to drive or affect reaction time

14  Causes o Damaged exhaust o Driving in an area with insufficient ventilation o Starting vehicles in a garage with the door closed o Smoking with the windows closed  Symptoms o Headache, nausea, drowsiness, confusion, and/or loss of strength  End result o Unconsciousness o Death

18  Busy schedule  Not enough sleep  Personal problems at work, home, or school o Stress causes adrenaline rushes, muscle tension, increased breathing and heart rates, sweaty palms, headaches, and extreme fatigue.

19  Plan ahead to reduce stress o Allow extra time during rush hour or bad weather o Map your route before leaving o Call ahead if you are late

20  Major source of anxiety is driving in unfamiliar surroundings o Panic sets in and it is easy to miss or overlook critical information  Being too excited can decrease your attention and increase your willingness to take risks.  Depression can affect your concentration and coordination  Best thing to do is have someone else drive for you
