Service 188 is a inter-town route plying between Choa Chu Kang, Bukit Gombak, Bukit Batok, Toh Tuck, Pasir Panjang and HarbourFront. The route is frequented between Choa Chu Kang Town Centre and Bukit Batok as a valuable inter-town connections, as well as between Bukit Batok/Toh Tuck and Pasir Panjang, linking the many industries located around Pasir Panjang to the housing estates up north.
Demand for the service moderate during offpeak hours, but receives high demand during peak hours, and operates a proportionately large split-shift fleet to cope with demand.
Formerly a Singapore Bus Service (SBS) route introduced in 1998, the route was transferred to Trans-Island Bus Service (TIBS) a year later (in 1999) and has been operated by SMRT ever since. High capacity articulated (and thereafter, double-deck buses) are deployed on a daily basis.
