If the flashing lights were on then you violated the law. If they got your license number you will get a ticket. If not then you are safe. In the future when you see a school bus prepare to stop at any moment.
In nearly all jurisdictions you are required by law to stop a reasonable distance before you reach the back of the bus (if you are approaching from the rear) or before you draw even with the front of the bus (if you are approaching from the front. Wait patiently until the red lights are no longer flashing and then proceed. A word of warning though. Stopped school buses may have just let children off the bus and said children are prone to running across the road without looking, so watch for children AFTER the bus starts moving. It may be legal to proceed, but if you hit some kid, that will be of little consolation (even if it isn't otherwise your fault).
It means that the bus is about to pull into the lane of travel (presumably from a bus stop), and that you are expected to yield to the bus to let it in.
Red lights flashing on a school bus mean remain stopped until they are turned off.
If it's a school bus, whenever the lights are flashing.
You should remain stopped until the bus's red lights are no longer flashing.
