A track day is an organised event in which non-members are allowed to drive or ride around established motor racing circuits, or alternatively (though far less common) on closed or disused airfields.[1] Most race tracks around the world now provide this facility, where a road legal or track prepared car or motorcycle can be used without speed restriction (as if racing, though the practice of actual racing is almost exclusively forbidden at these events) by members of the public. Criteria for being eligible to participate is usually the holding of a driving licence for the vehicle in question or the appropriate racing license for the event can also be used and the payment of a fee.
