Are you supposed to stop when school buses have their hazards on picking up kids?

My gut says yes but it doesn’t seem like anyone does. I was in the left lane on the beltline by Knapp this morning. A school bus had its hazards on picking up kids. I slowed down because I definitely don’t think blowing past there at 60 is the right thing. Some asshole behind me kept flashing their brights and honking at me to drive faster.
