The invention discloses a telescopic annunciator. The telescopic annunciator comprises a tank, and is characterized in that a warning sign is arranged on the frontal surface of the tank, wherein a left side warning board and a right side warning board are mounted in the tank, are respectively mounted in the tank in a sliding manner, and can respectively slide outside the tank. The annunciator is set in the tank shape; the warning sign is arranged on the frontal surface of the tank, and fits the left side warning board and the right side warning board capable of extending outside the tank; when the annunciator is not used, the two side warning boards can be put into the tank for conveniently carrying, transporting and storing; and when the annunciator is used, the warning sign on the frontal surface of the tank can be singly used according to the use environment, or can fit the left side warning board and/or the right side warning board (extending outside the tank) to increase the warning area, so that the warning effect is improved, drivers are easy to see the annunciator, and the use safety is greatly enhanced.
