Step-by-step solution
1. Examine the primary purpose of installing Reflective Pavement Markers (Road Studs) on highways. 2. Recognize that they reflect headlight beam light back to improve nighttime visibility of lane boundaries and guide drivers through curves. 3. Select Option C as the correct choice.
Explanation
Reflective pavement markers, also known as road studs or cat's eyes, reflect light from vehicle headlights back towards the driver. This clearly outlines lane markings, road edges, and dangerous curves at night or during poor weather conditions, helping drivers navigate safely.
Shortcut
To remember the primary purpose of Reflective Pavement Markers (Cat's Eyes), use the phrase "Cat's Eyes = Night Vision": - Cat's Eyes: Reflect headlight beams back to drivers, just like a cat's eyes glow in the dark. - Night Vision: Improve nighttime visibility of lane boundaries and safely guide drivers around curves.
Common mistake
A common mistake is selecting Option D by confusing road studs with rumble strips or speed breakers intended to slow down traffic. In reality, road studs are designed to be retroreflective safety markers that enhance nighttime visibility and lane discipline without acting as physical speed barriers. Another mistake is selecting Option A by assuming they serve a decorative or aesthetic purpose rather than a critical safety function.
Correct answer: C) Improve nighttime visibility of lane boundaries and guide drivers through curves.
