(of a moving ship or aircraft) twist or oscillate about a vertical axis.

Basically when the car rotates/turns

I'd love to piggy-back on this topic from N12ck, since I've been thinking about this based on the common use of the term on this site when talking about things like U-shaped sidepods, and shark fins.

What are the typical max sideslip angles an F1 car would typically see? I understand how this works in aircraft, but am not sure about the terminology for road cars. As I understand it, the only time a car actually experiences a sideways component of wind is if there is a skid (like Vettel's powerslide during qualifying). If a vehicle is going around a turn without losing traction, it is yawing but there should be hardly any sideslip angle?

Thanks to anyone who can educate!

Yes. Yaw and slip are two distinct concepts. Yaw is a change in orientation while slip is direction of movement relative to orientation. Crossed rudder and ailerons can slip an airplane without yawing it. And as you note, a vehicle can yaw without slip (ignoring probable tire slip angles).

A F1 car will have tire slip angles, but I'll leave this guesstimate to the better informed.
