Upon arrival, how many feet from the scene must units turn off all radio equipment?

• A. 100 ft
• B. 200 ft
• C. 300 ft
• D. 400 ft

Answer: (C)

Getting a radio-free buffer around the scene is essential to protect evidence and avoid radio frequency interference with investigative equipment. Turning off all radio equipment within 300 feet of the scene provides a practical separation that minimizes transmissions from contaminating recordings, affecting delicate devices, or masking details investigators are documenting. This distance balances safety and coordination: far enough to shield the immediate area from RF noise, yet not so far that on-scene communication becomes impractical. Distances like 100 or 200 feet don’t provide a reliable buffer, while 400 feet is broader than necessary and would hinder on-scene coordination.
