ABSTRACT:
A system and method are provided for controlling the movement of a golf cart relative to a selected restricted area on a golf course, such as a green. A signal transmitter having a transmitting antenna is postioned in the vicinity of the selected restricted area. A transmission signal is produced from the transmitting antenna at the selected restricted area. A signal receiver having a receiving antenna is positioned on the golf cart for receiving the transmission signal when the golf cart moves into the vicinity of the transmitting antenna. An alarm on the golf cart is activated when the transmission signal received by the receiving antenna reaches a predetetermined level for indicating to an operator of the golf cart that the cart has moved into the restricted area on the golf course. The activation period of the first alarm is timed so that a second alarm on the golf cart can be activated after the expiration of a predetermined time period of activation of the first alarm. The second alarm provides notice to the cart operator that the cart has remained in the restricted area for the predetermined time period. The golf cart may also be disabled in the forward direction after a predetermined time period of activation of the first alarm to prevent further ingress of the cart into the restricted area.
