Abstract: A seat belt usage indicating device for indicating that a male portion of a seat belt is engaging a female portion of a seat belt buckle. The seat belt usage indicating device includes a housing. The housing has a front wall, a back wall, and a peripheral wall extending therebetween. The peripheral wall has a slot therein for releasably engaging a male portion of a seat belt buckle. A plate extends away from and is integrally coupled to the peripheral wall. The plate is adapted for removably extending into and releasably engages the female portion of a seat belt buckle. Control circuitry is adapted for sending a signal to a speaker. The control circuitry is securely mounted in the housing. A sensing means for sensing the male portion is positioned in the housing such that male portion may engage the sensing means. The sensing means is electrically coupled to the control circuitry. A speaker for emitting a sound is securably mounted in the housing and extends outwardly from the front wall.
