  2. Components of the HTS • People • Machines • Environment they operate them in North Carolina Driver and Traffic Safety Education Association

  3. Cause for most motor vehicle crashes • 90-95% of vehicle accidents are caused by people not vehicles or roadways. • Human errors are the problem in traffic accidents. North Carolina Driver and Traffic Safety Education Association

  4. Purpose of driver licensing. • The purpose of driver licensing is to make sure that no user of the HTS is an unreasonable risk to other users of the system or themselves. North Carolina Driver and Traffic Safety Education Association

  5. Importance of vision on driving • Most information used when using the HTS, is acquired visually. • Generally, it is accepted that 90% of driving information is received through the eyes. North Carolina Driver and Traffic Safety Education Association

  6. Things that may affect a person's vision • Genetics • Fatigue • Smoking • Alcohol or other drugs North Carolina Driver and Traffic Safety Education Association

  7. Things that may affect a person's vision • Age • Illness such as allergies or colds • If 90% of driving information is received visually, we must have reasonable vision. • NC requires 20/40 correctedvision. North Carolina Driver and Traffic Safety Education Association

  8. Field of vision. • Field of vision is all the area you need in front of you. • Normally people can see 180-210 degrees of the area to the front. North Carolina Driver and Traffic Safety Education Association

  9. Components of field of vision • Central vision is the area where you see things clearly. The DMV eye test measures visual acuity, how clear central vision is. • Fringe Vision is outside central vision where you can recognize objects but not clearly. • Peripheral vision is the outside of your field of vision where you see motion but not objects. North Carolina Driver and Traffic Safety Education Association

  10. Things that may affect a person's field of vision. • Tunnel vision caused by genetics. • Other traffic blocking parts of your field of vision. • Your vehicle's design can block your vision. • Illness, even temporary illness can cause vision restrictions. • Age can reduce a person's field of vision as well as the other effects age can have on vision. North Carolina Driver and Traffic Safety Education Association

  11. Depth perception. • Depth perception is the ability to judge distance. North Carolina Driver and Traffic Safety Education Association

  12. Effect color blindness may have on driving • Although red and green are typically the affected colors, persons who are colorblind can compensate for the problem and are no greater risk of collisions because of their problems. North Carolina Driver and Traffic Safety Education Association

  13. Glare resistance and glare recovery • Glare resistance is the ability of the pupil to shut out light (glare). • Glare recovery is the ability of the pupil to reopen once the bright light is gone and the eye needs to readjust to low light conditions. North Carolina Driver and Traffic Safety Education Association

  14. Alcohol as a sedative • Alcohol is a sedative. • It affects many areas of the body from mental functions to relaxing muscles and reflexes. North Carolina Driver and Traffic Safety Education Association

  15. Ways alcohol sedates the eyes • Slowing the pupil, increasing glare and slowing glare recovery. • Relaxing the muscles that control the lens reducing visual acuity. • Sedating the retina causing problem of color recognition especially shades of darkness while driving. (Seeing pedestrians, bicycles or even the side of trains at night.) North Carolina Driver and Traffic Safety Education Association

  16. Ways alcohol sedates the eyes • Binocular vision is the ability of the eyes to focus together on an object. • Peripheral vision can be narrowed by alcohol. North Carolina Driver and Traffic Safety Education Association

  17. North Carolina and DWI laws • Laws DWI (Driving While Impaired) only requires that a person have a blood alcohol concentration of.08 to be convicted of DWI. • One reason is that no one can see well enough, even at .08 BAC to drive safely. They are an unreasonable risk. North Carolina Driver and Traffic Safety Education Association

  18. Disabilities, which may affect a person's fitness to drive • Hearing loss. There is usually no increased risk because of visual compensation by the driver. • Physically challenged persons are not normally a greater risk. Safe driving is a mental skill so physical limitations can usually be overcome. North Carolina Driver and Traffic Safety Education Association

  19. Disabilities, which may affect a person's fitness to drive • Age. Aging affects all of a person's senses, including vision, hearing, reactions, and even mental sharpness. These effects often appear over years and sometimes not recognized by persons as they age. • Epileptics are allowed to have a driver's license (class C) if they are on medication and have gone seizure free for one year. North Carolina Driver and Traffic Safety Education Association

  20. Disabilities, which may affect a person's fitness to drive • Diabetes is a major problem because of the serious effect of high or low blood sugar. • Mental ability. North Carolina requires at least a 75 IQ in order to get a driver's license. North Carolina Driver and Traffic Safety Education Association
