Maximum Speed. Each track shall have a maximum speed which ensures safe operation. The maximum speed shall be one of the following: The speed established by the Commissioner, after such investigation as the Commissioner deems appropriate; or If the Commissioner does not establish a maximum speed, the speed established by the owner based on the following considerations: Track design, including the grade; Track surface; Radius of the curves; and Age of the riders.
