No, when you are approaching a stopped school bus from the opposite direction on a road that has two or more lanes in each direction, you are not required to stop and may continue carefully. This is the only time you can pass a school bus that displays flashing red lights.
<h3>What you approach a school bus with flashing red lights ?</h3>
If red lights are flashing on the school bus, the law requires that motorists approaching from either direction come to a full stop and remain stopped until the bus's red lights no longer flash. This requirement applies not only on public highways but also on private roads and in parking lots.
While nobody likes being delayed, remember that It is illegal - and very dangerous - to pass a stopped school bus when red lights on top of the bus are flashing. These flashing lights mean the bus is picking up or discharging students and you need to STOP even on divided and multi-lane highways.

B) Plenum cables must be used for this project.
A plenum cable must be installed in each "air carrying" space. For example, most large office buildings use the ceiling to return air to the air conditioning system. This qualifies this ceiling as a plenum ceiling and all cables passing through this ceiling must be plenum rated.
Plenum cable /ˈplɛnəm/ is an electrical cable that is installed in the plenum space of a building. In the United States, plastics used in the construction of plenum wiring are regulated by the National Fire Protection Association's standard NFPA 90A: Standard for Installation of Air Conditioning and Ventilation Systems.
