How does a negative caster angle affect a vehicle?

A negative caster angle can lead to instability in steering, causing the vehicle to wander. Caster is the angle formed by the steering axis in relation to the vertical axis when viewed from the side of the vehicle. A negative caster angle means that the top of the steering axis leans towards the rear of the vehicle, which disrupts the natural self-centering ability of the steering system.

As a result, the vehicle may not track straight and can feel loose on the road, making it more difficult for the driver to maintain directional control. This can lead to a sensation of wandering, especially at higher speeds or on uneven surfaces. Maintaining proper caster angles is crucial for balanced steering dynamics and overall vehicle stability, which is why a negative caster angle is linked to this wandering effect. Additionally, the other provided choices do not accurately describe the implications of a negative caster angle in vehicle dynamics.
