Consider the following statements: A 4-wheel vehicle moving a sharp circular path at high speed will 1. Overturn about its outer wheels 2. Overturn about its inner wheels 3. Skid outwards 4. Skid inwards Which of these statements are correct?

When a four‑wheeled vehicle negotiates a sharp curve at high speed, the required centripetal force acts inward while the inertial (centrifugal) tendency acts outward. That outward tendency produces a roll moment that lifts the inside wheels and makes the vehicle pivot about the outer wheels, potentially causing a rollover about the outer wheels [1]. If the lateral friction is insufficient to provide the needed centripetal force, the vehicle will also slide outward off the curved path (skid outwards) rather than track inward [1]. Therefore statements 1 and 3 are correct; overturning about inner wheels and skidding inward are not expected in this scenario.
