SIX buses operating for about 30 years have been given 24 months by the Land Transport Authority to cease operations.
It is part of the authority's move to make buses safe for the travelling public.
While the authority is not revealing the names of the bus companies, LTA spokesperson Alfred Wiliame said their investigations identified that the six buses were not safe to operate on the roads.
Mr Wiliame said the identified buses had exceeded their lifespan.
"It can be a safety risk to passengers and that's why we are taking action against the bus companies now," he said.
He said the bus companies that were identified had no option but to take the buses off the roads within the 24-month period.
"These buses are operating in the Central, Eastern and the Western divisions.
"The authority understands that the buses cannot be removed immediately from the streets because they need to serve the public as well," he said.
