Service 183 is both a residential and an industrial route, serving housing estates around Toh Guan, Clementi and Pasir Panjang, as well as industries along Toh Guan Road East, Toh Tuck, and Singapore Science Park II. The route connects these areas to Clementi Town Centre and Jurong East Regional Centre.

This service experiences high demand during the peak hours from the various industries along its route, and as such, operates a proportionately large split-shift fleet to cope with increased passenger loading.
