The government has not issued any directives to any highway concessionaire on toll rates, Works Minister Datuk Fadillah Yusof said.

He said based on the concession agreements, some of the highways were to increase toll rates in 2014.

"However, the government has yet to issue any directives on this to the companies involved," he said in a statement to Bernama here Friday night.

Instead, he said the government was still deliberating on the best steps to take to mitigate the impact on the people in case toll rates were increased by considering the views of various quarters.

He said this included the setting up of a special laboratory which would be handled by the Performance Management and Delivery Unit (PEMANDU) to study the implications of toll rate hikes in 2014.
