Question

Overturning of vehicles on a curve can be avoided by using a:

• A. compound curve
• B. vertical curve
• C. reverse curve
• D. transition curve

Hint:

Transition curves help ensure gradual change in curvature, reducing overturning risk.

Answer 1

The Correct Option is D

Transition curves are introduced between straight and circular paths to provide a gradual change in curvature and super elevation. This reduces the risk of vehicle overturning by ensuring a smoother transition in centrifugal force.
