Question
Can children ride for free on MTA subways and buses?
Answer
Children under 44 inches tall ride free of charge on New York City Transit
subways and on local buses of New York City Transit and MTA Bus. No more
than three children per adult may ride free. On express buses, children two
and under may ride for free only if they sit on an adult's lap.
