From early afternoon on May 2, traffic on the Ho Chi Minh City–Trung Luong Expressway toward the city was heavily congested, with vehicles moving at a crawl. A stretch between Km49 and Km38 saw particularly long backups.
At around 1 p.m., a collision between two cars at Km17 on the same expressway, in Tay Ninh Province and heading toward Ho Chi Minh City, worsened the situation, triggering multi-kilometer tailbacks.
As evening approached, traffic volume continued to rise along the My Thuan–Trung Luong–Ho Chi Minh City corridor, with recurring congestion. At 5:30 p.m., authorities temporarily closed the entrance ramp to the expressway at the Than Cuu Nghia interchange to ease traffic pressure.
On the same day, severe congestion was also reported on National Highway 1 through key intersections in Tay Ninh Province, including Ben Luc, Nhut Chanh, and Long Kim, primarily affecting lanes heading into Ho Chi Minh City. Traffic consisted mainly of private cars and interprovincial buses.
