Its an OAC bus . Infact , i've seen more roaches on OAC buses
than CAC ones . All those sweet wrappers , tissue papers and food
wrappers are where they are breeding . The Hispano Carrocera rather
darkish interior bodywork makes it a good place for them to breed
but i think its high time SMRT should get rid of these pests. SBST
buses also suffer from litter problem too for some buses , but
strangely enough , i've yet to see a roach.
