Which geometric design element is crucial for maintaining vehicle stability on curves?

Step 1: Understand that when a vehicle goes around a curve, it experiences forces that can make it unstable.
Step 2: Learn that these forces are called lateral forces, which push the vehicle outward from the curve.
Step 3: Know that to help keep the vehicle stable, the road can be designed to tilt or slope towards the inside of the curve.
Step 4: This tilting of the road is called superelevation.
Step 5: Realize that superelevation helps counteract the lateral forces, making it easier for the vehicle to stay on the road.
