Regulatory Signs
School Bus Stop Arm Sign
A school bus stop arm accompanies its flashing red signals while children load or unload.
What to Do
Stop as required and wait until the bus’s signals allow traffic to proceed.
A Detail to Remember
The arm uses the familiar red octagon so the stop instruction remains recognizable on the side of a vehicle.
Understanding Regulatory Signs
Regulatory signs communicate instructions road users must follow. Read supplementary wording carefully: the vehicle type, road layout or time of day can affect how an instruction applies.
