A track day is an organized event in which participants are allowed to drive or ride around established motor racing circuits. Most race tracks around the world now provide the ability to conduct this activity, 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 are usually the holding of a driving license for the vehicle in question or the appropriate racing license for the event can also be used and the payment of a fee.
