The Transport Ministry has ordered public and private interprovincial bus services to cut fares by 1 satang per kilometre, not 3 satang as predicted earlier, following a fall in diesel prices.
The new fares will take effect on Feb 15.
Deputy Transport Minister Omsin Cheevapruek said the ministry settled on a 1 satang reduction because it was worried a bigger cut could affect businesses.
The bus operators had already cut fares by 3 satang per km in August 2015.
They complained that despite lower fuel costs reducing overheads, business had been affected by tougher competition - especially from low-cost airlines - and their passenger loading had dropped to only 40-50% per trip.
