According to AASHTO guidelines, sight distance along horizontal curves is detailed in which chapter?

• A. Chapter 1
• B. Chapter 2
• C. Chapter 3
• D. Chapter 4

Answer: (C)

The correct reference for sight distance along horizontal curves, as detailed by AASHTO guidelines, is Chapter 3. This chapter specifically addresses geometric design principles, including considerations for safe sight distances on curves. Proper sight distance is critical for ensuring that drivers can see and react to conditions ahead, enhancing safety and operational efficiency on roadways. The guidelines emphasize factors such as the radius of the curve and the speed of traffic to determine the appropriate sight distance needed for various scenarios. This information is essential for transportation engineers when designing horizontal curves to ensure that they meet safety standards and provide adequate visibility for drivers navigating those curves.
