Glare screens are traffic safety products manufactured to be installed on the median of highways to address headlight glare from opposing vehicles. They are commonly set up on highway median guardrails or in the center of them, and some are also placed on sliding median gates. They are categorized by material into steel, plastic, and fiberglass glare screens. Aesthetically, they include standard flat plates, reverse S-shaped, embossed, and highway scenic glare screens.
