Inspection for Automatic color indication of retroreflective materials

This inspection checks retroreflective materials, like road signs and markings, to ensure they change color correctly when light is shone on them. Automatic color indication helps verify that the materials are working properly and will be visible to drivers at night or in poor visibility conditions. Inspectors use special tools to assess how well the materials reflect light and if the color changes meet safety standards. This is important for maintaining road safety and ensuring that signs are easily seen.
