Over the last 100 years, signs have changed radically. New materials have been developed to make road signs that stand up to harsh weather conditions, new pigments and films have been created to ensure that brightly colored road signs donot fall victim to sun bleaching, and new retro-reflective prisms have been employed to ensure that road signs reflect an appropriate amount of light from the appropriate angle depending on where they are used.

TYPES OF SIGNS:
  • Directional signs
  • Regulatory Signs
  • Warning Signs
  • Information Signs
