What is the minimum mounting height from the roadway to the bottom of an electric arrow panel?

The minimum mounting height from the roadway to the bottom of an electric arrow panel is 7 feet. This height is established to ensure visibility for drivers while allowing enough clearance to avoid obstruction from vehicles or debris on the roadway. Maintaining this height not only aids in clear sight lines for approaching traffic but also conforms to safety regulations set forth for traffic control devices.

Adhering to this guideline is crucial for effective communication of directional information to drivers, particularly in areas where visibility might be challenged by road conditions, weather, or surrounding infrastructure. It’s important to prioritize safety on the road by placing these devices at heights that maximize their visibility and effectiveness.
