Final answer:
The yellow diamond sign with two lines, one straight and one slanted, indicates a divided highway ahead. The sign alerts drivers of the road splitting into separate carriageways and forms part of the overall road safety and information system.
Explanation:
A yellow diamond road sign with two lines, one straight and one with a slant in the middle, warns drivers of a divided highway ahead. This type of sign is designed to alert drivers that the roadway is splitting into two separate carriageways for traffic in opposite directions.
It's crucial to understand road signs to ensure safe driving, especially when approaching specific road features such as steep grades, curves, or where the structure of the highway changes. Understanding road gradient is also vital for vehicle control on sloped roads.
For example, a sign indicating a '6% Grade' informs drivers of the incline or decline they are about to encounter, which affects speed and vehicle handling. Similarly, race car drivers aim to take the inside path around a curve to maintain the highest speed, a principle that informs how civilian drivers should approach highway curves and ramps onto limited access roads. Therefore, the correct answer to the student's query is d) Divided highway.
