*Question E1B07:
[97.15] To what type of regulations does PRB-1 apply?*  

*Correct Answer is  C: State and local zoning*  

### AI Response: (may contain errors)  

PRB-1 is an important FCC policy that addresses the rights of amateur radio operators in relation to state and local zoning regulations. Here's a breakdown of why the correct answer is correct and why the other choices are incorrect:

1. **Correct Answer: State and local zoning (C)**  
   - PRB-1 is a memorandum from the FCC that requires state and local governments to reasonably accommodate amateur radio operations. It emphasizes that while local authorities can regulate the placement, screening, and height of amateur radio antennas, they must not preclude amateur communications. This means that any zoning regulations must allow for effective amateur radio operations.

2. **Why the other choices are incorrect:**
   - **Homeowners associations (A):** PRB-1 does not apply to private agreements such as those with homeowners associations. These are typically governed by covenants, conditions, and restrictions (CC&Rs), which are not covered by PRB-1.
   - **FAA tower height limits (B):** The FAA regulates tower heights primarily for aviation safety, and PRB-1 does not address these federal regulations.
   - **Use of wireless devices in vehicles (D):** PRB-1 is unrelated to the use of wireless devices in vehicles. It specifically pertains to zoning issues related to amateur radio antennas.

In summary, PRB-1 is focused on ensuring that state and local zoning laws do not unreasonably restrict amateur radio operations, making option C the correct choice.
