Bus Service 991 is a trunk service plying between Bukit Batok and Choa Chu Kang, connecting many residential estates around Bukit Batok, Bukit Gombak, Choa Chu Kang and Keat Hong with the transport nodes of Bukit Batok, Bukit Gombak and Choa Chu Kang MRT stations and their nearby amenities.

When initially introduced on 8 July 2018, Service 991 plied an interim routing from Bukit Batok Interchange and looping at Bukit Batok West Ave 5, mainly complementing Service 941 and 944 in serving new residential estates northwest of Bukit Batok with direct links to Bukit Batok MRT Station.

Thereafter, it absorbed the route of Feeder Service 308 (withdrawn on the same day), via Choa Chu Kang Ave 1, Choa Chu Kang Drive and terminating at Choa Chu Kang Interchange.
