      • Color plays an important part in road safety.
      • Drivers must instantly recognize traffic lights, indicator signs, hazard warning lights and stop lights.
      • People with color vision limitations may react slower to them.
      • Avoid using medium or dark blue sunglasses, because they can seriously interfere with some people’s ability to distinguish traffic light colors.
      • A person who is colorblind is able to drive in Illinois.
      • Colorblind individuals can identify signs and signals by:
        • Shape
        • Position
        • Reading the words printed on them
