What height is typically required for a traffic signal to be installed?

The typical height required for a traffic signal to be installed is between 12-15 feet. This height is ideal for ensuring that the signals are clearly visible to drivers and pedestrians, reducing the chances of accidents and confusion. Installing traffic signals at this height allows drivers to see the signals from a distance, ensuring they have enough time to react to the traffic control measures presented. Furthermore, this height is generally consistent with standards set by traffic management authorities to enhance visibility while also ensuring the signals are not obstructed by vehicles or other infrastructure. Heights below this range may lead to reduced visibility, particularly for taller vehicles, while heights above could diminish the signal's effectiveness and clarity for drivers.
