There is no regulation about free fares for people accompanying older people in urban and semi-urban regions. Some people file a lawsuit to get this benefit. The interstate collective public transportation (the Free Pass program) warrants free companion fares once one proves not having financial means for paying the companion’s tickets. When a medical report states the need of a companion, the accompanying person is entitled to receive free fares (Brazilian Ministry of Infrastructure, 2019).
