Kosmo reported that traffic flow from the Gombak toll plaza towards the east coast on the highway was already congested at 4.30pm.
It said traffic was especially slow near the Genting Highlands turn-off due to the increase in the number of vehicles on the highway.
Traffic on the East Coast Expressway 1 and 2 remains smooth.
On the North-South Expressway (PLUS) an increase in motorists had reportedly caused traffic jams near Seberang Jaya.
Highway concessionaire PLUS Malaysia Bhd previously said it expected two million vehicles to use its highways daily from today until Monday as people head back to their hometowns for Aidiladha.
It advised road users to plan their travels and check for traffic updates.
