• A. 8
• B. 12
• C. 10
• D. 15

Answer: (B)

The main idea is ensuring safety clearance for lighting fixtures installed over lanes that vehicles travel. Lamps and lampholders positioned over those lanes must be high enough so tall vehicles won’t hit them and so maintenance and service access aren’t hindered, while still providing good illumination. Not letting the fixtures sit too low prevents collisions and damage, and 12 feet above the floor strikes a balance between keeping enough vertical space for typical vehicles and keeping the lighting effective along the lane. Heights much lower would risk strikes, while going much higher can reduce lighting effectiveness near the floor. So, the minimum height is 12 feet above the floor.
