Q. Can a bus driver that takes non- Jewish children to a treatment centre, do so on Tisha Beav before Chatzos (midday)? It is an important part of the drivers monetary support.

A. Horav Dovid Pam and Horav Aharon Miller Shlit’a maintain that it is permitted since it is necessary.
After all we are permitted to travel and sit in a car when going to shul during Tisha Beav.
