Why does traffic seem to be twice as bad when school is in session?

Lifelong American here. I can understand the morning rush hour but afterwork traffic is horrendous. School buses are usually off the road by this time. Also the highways are bad during the school months and busses don't go in highways. What gives? Domino effect?
