All highways leading toward Klang Valley experienced smooth traffic flow in the morning of June 7, 2026, according to highway authorities [1, 2]. However, traffic conditions were expected to worsen from midday into the evening as holidaymakers returned after school and public holidays [1, 2, 3]. By around 2pm, slow traffic was reported on major highways leading into Kuala Lumpur, including the North-South Expressway southbound from Seberang Jaya to Prai and Bandar Cassia to Jawi, PLUS E2 from Senawang to Port Dickson, and the KL-Karak Expressway from Gambang to Sri Jaya [3]. Despite these slowdowns, overall traffic remained under control with no extraordinary congestion or major incidents apart from one fatal crash [3].
At about 6:30pm, a fatal motorcycle accident occurred at Km171.3 northbound on the Bandar Baharu-Jawi route, blocking the emergency lane and causing further slowdowns [4]. Traffic was also slow on several other major routes in the evening, including northbound from Perai to Juru, southbound from Simpang Renggam to Sedenak and Kulai, and the Kuala Lumpur-Karak Expressway near Lentang and Gombak Toll Plaza [4]. Meanwhile, the East Coast Expressway (LPT 1 and LPT 2) maintained smooth traffic flow as of 8pm [4].
To ease congestion, highway authorities activated Smart Lanes using emergency lanes at strategic points [3]. Motorists were advised to be cautious due to rain in Klang Valley and southern regions and to plan travel times to avoid traffic jams [1, 2]. They were also reminded to check vehicle conditions, ensure sufficient balance on Touch 'n Go cards or e-wallets, and stop at rest areas if feeling tired [4].
