- Operation Instructions
After the school bus starts off, press the stop sign control switch to open the stop sign. After the stop sign is activated, it rotates by 90 degrees clockwise and four LED lights on the stop sign are turned on.
Press again the stop sign control switch to retract the stop sign counterclockwise.When the stop sign is retracted to zero degree (in parallel with the school bus), all 4 LED lights on the sign go out.
whatever state the stop sign may be in, when the stop sign is artificially pulled or pushed after the bus is ignited on, the stop sign will be resumed to the state defined by the control switch. When the stop sign is blocked by external force during rotation, the rotation will stop after 25 seconds
When the school bus reaches 5KM/H, the stop sign, if unretracted as the school bus starts off, will be retracted automatically, in order to protect the stop sign from scratching or impacting into other objects and to reduce traffic accidents.
