High voltage power lines must be a minimum of how many feet above the ground where traffic travels?

High voltage power lines must be a minimum of 20 feet above the ground where traffic travels to ensure the safety of vehicles, pedestrians, and equipment that may come into contact with these lines. This height serves as a standard to prevent accidental strikes by tall vehicles, such as trucks or construction equipment, which could cause serious accidents or power outages.

Maintaining a clearance of 20 feet helps to mitigate the risks associated with low-hanging power lines, especially in areas where traffic is frequent and varied in height. Adhering to this regulation ensures compliance with safety codes designed to protect public safety and minimize hazards in areas where electrical infrastructure intersects with transportation routes.
