Choose the correct answer
A
Road markings become invisible
B
Tractive effort demand increases on curves
C
Rainfall reduces to zero
D
Signs become triangular
Correct Answer
B. Tractive effort demand increases on curves
Why is this the answer?
Curvature adds resistance, so steep grades on curves may require compensation. Reference: IRC geometric design vertical alignment - grade compensation concept
