BACOLOD CITY, Philippines -- Many jeepney drivers in Bacolod City have begun began implementing a voluntary fare roll back, charging only P7 instead of the government-approved P7.50 since Monday.

However, a few drivers continued to charge P7.50, refusing to cooperate with the call of the United Negros Drivers Operators Center (UNDOC) and the Federation of Bacolod City Drivers Associations (Febacda) for a voluntary fare cut.

"The majority of the drivers have rolled back their fares but there are a few who have not. And we cannot compel them to do so since the move is voluntary," Elizabeth Katalbas, Febacda president, said.

Katalbas said some drivers even began charging P7 starting Friday, following a series of gas and diesel price rollbacks.

Diesel now sells at P36 a liter, making it viable to implement the voluntary roll back, according to Katalbas.

UNDOC secretary general Jesse Ortega said they volunteered to roll back the fare due to the decline in gasoline and diesel prices.

But Ortega also urged oil firms to further reduce pump prices with the huge cut in fuel prices in the world market.
