All 18 highways which increased their toll rates since last Thursday are not categorised as inter-urban highways.

The Malaysian Highway Authority (LLM) in a statement Saturday said, inter-urban highways were highways linking one state capital to another state capital and forming a national highway network as they connected the rural areas to the towns.

"Geometrically, inter-urban highways have controlled access as commuters can only enter the highways via certain interchanges.

"Highways categorised as an inter-urban highway are the North-South and East Coast Expressways," the statement said.

LLM in the meantime also explained that the KL-Karak Highway (KLK) is not an inter-urban highway as the highway only connects Gombak and Bentong, Pahang.

In addition, KLK was constructed with intra-urban highway geometric characteristics with partially controlled access where there were intersections or at grade around the municipality.

KLK is only linking KL and Kuantan, the statement said. As such, according to LLM, there was no issue of the government not fulfilling its 13th General Election (GE13) Manifesto promises.

Among the promises mentioned in the 'Menepati Janji Membawa Harapan' manifesto launched by the Prime Minister and Barisan Nasional chairman, Datuk Seri Najib Razak in April 2013 was a reduction in inter-urban highway toll rates, to be implemented in stages.
