Mehadrin bus lines (Hebrew: קו מהדרין‎) were a type of bus line in Israel that mostly ran in and/or between major Haredi population centers and in which gender segregation and other rigid religious rules observed by some ultra-Orthodox Jews were applied from 1997 until 2011. In these sex-segregated buses, female passengers sat in the back of the bus and entered and exited the bus through the back door if possible, while the male passengers sat in the front part of the bus and entered and exited through the front door. Additionally, "modest dress" was often required for women, playing a radio or secular music on the bus was avoided, advertisements were censored. Mehadrin lines were generally cheaper than other lines. In early 2010, there were 56 Mehadrin buses in 28 cities across Israel ope
