Unless otherwise posted, it is unlawful to use bicycles or other similar wheeled vehicles on trails. Further, it is unlawful for any person to travel on a trail at a speed greater than is reasonable and prudent under the existing conditions and having regard to actual and potential hazards. In every event, speed shall be so controlled as may be necessary to avoid colliding with others who are complying with the law and using reasonable care. Travel at speeds in excess of fifteen miles per hour on a walking/vehicle trail, unless otherwise posted, shall constitute in evidence a prima facie presumption that the person violated this section. Travel at speeds fifteen miles per hour or less shall not relieve the rider from maintaining control of themselves and their equipment, and from the duty to ride with due regard for the safety of all persons. Violation of any of the provisions of this section constitutes an infraction, and may be punished by a penalty of not more than two hundred fifty dollars. (Ord. 3360-13 § 25, 2013; Ord. 2442-00 § 9, 2000.)
