Health and Emotional State
Being in shape to drive is an important factor of your driving safety. Such health aspects as vision or hearing can significantly affect your driving performance. Good vision and hearing are essential for driving. A lot of your driving decisions will be based on what you can see and hear around you.
You are required to pass a vision test when you apply for your drivers license. Hearing is a more important part of driving than many realize. Your hearing can warn you of danger—the sound of horns, a siren, or screeching tires. Sometimes you can hear a car that you cannot see because it is in your blind spot.
