In an effort to reduce
its notoriously bad traffic problems, Jakarta installed its HOV regulations in 1992, using a «three - in - one» policy that required three passengers in each vehicle on some major roads, between 7 and 10 a.m. and between 4:30 and 7 p.m.. However, it suddenly scrapped the policy in 2016 — first for a week, then for a month, and then permanently.
