Answer :
Final answer:
The 'Road Shoulder Much Higher Than Road Surface' sign indicates that the road shoulder is at a significantly higher elevation than the road surface. The correct answer is option A).
Explanation:
The 'Road Shoulder Much Higher Than Road Surface' road sign indicates that the road shoulder has a significantly higher elevation than the road surface, which is option A. This means there is a difference in height between the road surface and the adjacent shoulder, a situation that can be potentially hazardous, especially if a vehicle pulls off the road suddenly.
Understanding the slope or grade of the road, as indicated by signs stating a certain percentage, is crucial for drivers. A grade sign shows how much the road elevation changes relative to a horizontal distance. A 6% grade means the road rises or falls 6 feet for every 100 feet of road, signifying the steepness of the terrain.
Knowing whether a slope is positive or negative is essential for safe driving practices, as it allows drivers to anticipate road conditions ahead. Banking is also a consideration in road design to prevent vehicles from skidding or overturning due to inclines.
