A school bus has a stop sign hinged on a sealed electrical actuator assembly that is attached to the side of the bus. The actuator assembly includes the electrical and mechanical components including an electric motor that pivot the hinged stop sign from a stored position adjacent the bus to an operative position extending outwardly of the bus in perpendicular fashion and back to the stored position. These components and wiring harnesses are protected in an outer sealed housing that has a removable cover to facilitate installation and repair. Installation and repair is further enhanced by a removable inner housing sub-assembly that carries a motor control circuit for the electric motor and provides additional protection for the electric motor. The school bus also has a crossing arm hinged on an identical sealed electrical actuator assembly, that is attached to the front bumper of the bus near the passenger door.

Un autobus scolaire est muni d'un panneau d'arrêt articulé sur un montage d'actionneur électrique scellé et fixé sur la paroi latérale de l'autobus. L'actionneur comprend des composants électriques et mécaniques, notamment un moteur électrique, qui font pivoter le panneau articulé d'une position de rangement le long de la paroi de l'autobus à une position extérieure et perpendiculaire à ladite paroi et qui ramènent ledit panneau en position de rangement. Ces composants ainsi que le faisceau de fils électriques sont protégés à l'intérieur d'un logement scellé externe muni d'un boîtier amovible qui facilite les opérations d'installation et de réparation. Ces opérations sont également facilitées grâce à un sous-ensemble amovible contenu dans le logement et comprenant un circuit de commande pour le moteur électrique. L'autobus scolaire est également équipé d'un bras de traverse articulé sur un montage identique d'actionneur électrique scellé, lequel est fixé sur le pare-chocs avant de l'autobus, à proximité de la porte passagers.
