Open test days

NO passengers are allowed on open test days

If you are driving a race-prepared car, full race gear is required.

If you are driving a street car (when allowed), closed-toed shoes, long pants, long-sleeved shirts, and a helmet are required. Course configurations for open testing days are generally determined by the track being used for the weekend's event. Testing fees, course configuration, and sessions are subject to change.

Previous track experience is suggested to participate

Note: If in the opinion of the Track Management an individual is unqualified to operate a vehicle within the facility at any time, or is posing a threat to the well-being or safety of others, Track Management reserves the right to remove them from the track and property.
