The antonyms for the term "bus fares" are the costs that someone does not need to pay for using public transportation. Free transportation or subsidized transportation are two options that people can use in some places. Free transportation is a service provided by governments or public institutions to help people move freely, usually within a certain region. It is an excellent option for those without enough funds to pay for regular transportation, such as students or elderly people. Subsidized transportation, on the other hand, provides discounted rates for specific groups or individuals based on their income, age, or other factors. This affordability option helps people who struggle to cope with the high costs of public transportation.
