Driver Readiness Page 2 of 10 Physical Readiness When you drive, you get information from all of your senses. You see, hear, smell and feel the motion of the vehicle - all of this input helps you to be aware of your driving environment, to predict what might happen, and to assess how to react. This information is processed by your brain and keeps you aware of changing situations. Sensory input helps your brain understand and decide when to accelerate, steer or brake. You also need to be in general good health with no injuries or illness that might prevent you from operating your vehicle safely. Vision Vision is the primary sense used in driving. About 90% of the information required for safe driving relates to vision. Since 90% of the information required for safe driving relates to vision, the degree of accurate vision is essential. Visual acuity refers to the clarity or clearness of one's vision, a measure of how well a person sees. Visual acuity is a measure of the ability to identify black symbols on a white background at a standardized distance as the size of the symbols is varied. This acuity is dependent upon the retinal focus, the sensitivity of the nervous system elements, and the manner in which the brain interprets the information. The well-known phrase "20-20 vision" refers to the ability to read given letters at a standard length of an eye exam room, specifically the distance from the patient to the acuity chart, which is typically 20 feet. Good driver vision includes:· Contrast sensitivity · Substantial visual field of view · Glare recovery Contrast sensitivity is the capacity to sharply see the difference between two similarly colored objects. Often pavement markings are worn and tend to blend into the road. This can affect your ability to locate the lane boundaries and where the edge of the roadway is located. When driving, the inability to see the difference in contrast also affects distance judgment. An adequate visual field of view
