Restricted routes for heavy vehicles

A restricted route has been implemented on the Federal Highway between Sungai Rasau and Subang during workdays and peak hours. Heavy vehicles (except buses and tankers) with laden and unladen heavy vehicles weighing 10,000 kg or more are not allowed to enter the expressway between 6:30 am until 9:30 am during Mondays to Fridays (except public holidays). A compound fine will be issued to heavy vehicles which flout the rule.^[7]

Motorcycle lane hazards

The Federal Highway is well known as the first expressway in Malaysia to have motorcycle lanes. However, the motorcycle lanes in the Federal Highway are known for posing danger to motorcyclists, due to dark, narrow and poorly maintained lanes and ramps, dangerous sharp corners, vulnerable spots for robberies.^[8] This has been attributed to the fact that the motorcycle lanes were originally intended for bicycle riders,^[2] with the design speed limit as low as 60 km/h.^[9]

On 29 August 2016, the Ministry of Works (MOW) allocated RM 3.13 million to upgrade motorcycle lanes on the Federal Highway in areas that fall under its care. The allocation would cover costs for brightening dark areas, installing pump houses at flood-prone areas, painting road lines and tunnel walls, lane-widening, building overhead ramps, additional signage and repair of intersections.^[10]

On 21 October 2016, during the announcement of the 2017 Budget, Prime Minister Najib Tun Razak announced that RM29 million would be allocated to upgrading the motorcycle lane on the Federal Highway. This included enhancing the drainage system to prevent flooding and building two overhead ramps, to make it safer for motorcyclists who use the route.^[11]

Traffic congestion area along the highway

There are several areas along the highway regarded as a congested area:-

Electronic toll collection

As part of an initiative to facilitate smoother passage at the Batu Tiga and Sungai Rasau Toll Plazas on Federal Highway. On 10 July 2014, the highway operator, PLUS Expressways, announced that all toll transactions at both toll plazas would be conducted electronically via PLUSMiles cards, Touch 'n Go cards or SmartTAGs starting 1 September 2014. Besides being more convenient to Federal Highway users and reducing jams at toll plazas caused by cash-paying motorists, this move might had helped reducing risks of robberies at toll plazas faced by toll attendants, as there would have been less cash available.^[19] However, on 30 August 2014, the implementation of the ETCs at Batu Tiga and Sungai Rasau toll plaza was postponed by the federal government.^[20]

Since 22 November 2014, all toll transactions at Batu Tiga and Sungai Rasau toll plazas of the Federal Highway had been conducted electronically via PLUSMiles cards, Touch 'n Go cards or SmartTAGs.^[21]

Toll collection was discontinued since 1 January 2018.
