The Anti-glare Panel is a traffic safety product designed to mitigate headlight glare from oncoming vehicles, installed on the median of highways. They are commonly set on the median guardrails or in the middle of the guardrails, and some are installed on the central opening retractable guardrails. Categorized by appearance, the common types include straight flat panels, reverse S-shaped, embossed anti-glare panels, and highway landscape anti-glare panels.
