SEN. Sherwin Gatchalian on Tuesday asked the Senate to review the performance of toll operators as well as the powers and functions of the Toll Regulatory Board (TRB) following the glitches that marred the implementation of cashless toll operations.

“There is a need to review the concession agreements of existing tollway operators to check if the operation of their toll collection system conforms to the minimum standard specifications for operations and maintenance under toll operations certificate or agreement,” the vice chairman of the Senate Economic Affairs committee said.
