The Ghana Private Road Transport Union (GPRTU) has justified the 15% transport fares increment.
The increment was announced on Monday and expected to take effect on Thursday April 6,2017.
It comes at a time when government has abolished duty on the importation of spare parts and reduced the Special petroleum tax rate from 17.5 percent to 15 percent.
But the operators say prices of fuel as well as spare parts and batteries have gone up since the last review of transport fares last year.
Issah Kalifa, General Secretary of the Ghana Private Road Transport Union (GPRTU) told Starr News fares have not been increased since February 2016.
