Which of the following is a common roadway deficiency?

• A. View/sight obstruction (on/off road)
• B. Bridge height
• C. Lane width
• D. Sign color

Answer: (A)

Visibility is the key idea here. A view or sight obstruction on or off the road directly blocks a driver’s ability to see hazards, signs, signals, or pedestrians in time to react. When something narrows or hides the line of sight—like overgrown vegetation, parked cars near intersections, or a large billboard—it reduces reaction distance and heightens crash risk, making it the most common roadway deficiency encountered.

Bridge height and lane width are important design considerations, but they’re not as universally problematic as obstructed sight. Sign color matters for recognition, but standard colors are used to maintain visibility, so it’s less typically a common deficiency compared with obstructed views.
