What is the minimum height of a traffic signal head?

The minimum height of a traffic signal head is typically set at 15 feet to ensure that it is clearly visible to drivers and pedestrians, while also reducing the risk of obstruction from larger vehicles or other roadside elements. This height allows for adequate visibility across different types of roadways and traffic conditions, ensuring that signals can be seen even from a distance. Various regulations and guidelines provide this recommendation to enhance road safety and facilitate smooth traffic flow, demonstrating the importance of standardized heights in traffic management. The specific height can also account for local regulations or unique circumstances, but the common standard aligns with 15 feet in many jurisdictions.
