He said the last time express buses had a fare revision was in 2008 and there had been no adjustment since.

Ashfar said school bus operators were unlikely to be affected as they are allowed to adjust fares to match current fuel prices.

He said the association had been asking for express bus fares to be adjusted according to fuel fare hikes but their appeals had been ignored.

“The Land Public Transport Commission is holding a workshop to hear our thoughts.

“We hope something fruitful will come out from these talks,” he told FMT.

The five sen increase in diesel to RM2.20 per litre took effect today. RON95 petrol remains at RM2.30 per litre and RON97 at RM2.60 per litre.

Since Dec 1, 2014, fuel prices have been determined each month using the managed float system.

Meanwhile, Association of Malaysian Hauliers president Nazari Akhbar said big haulier companies had a “fuel adjustment factor” (FAF) mechanism where service charges would be adjusted automatically according to fuel prices.

As such, big haulier companies would adjust their prices.

He said small-time lorry drivers, who were not included as its members, would have to tighten their belts to attract business.
