In October 2026, the Traffic Police Department under the Ministry of Public Security suspended speed measurements and penalties for vehicles traveling below the minimum speed limit on highway inclines. This measure, effective October 1, was implemented to allow for a safety assessment following reports that heavy trucks and tractor-trailers struggled to maintain the required 60 km/h on steep sections of several expressways, including the Phan Thiet - Dau Giay, Vinh Hao - Phan Thiet, and Nha Trang - Van Phong routes. Authorities noted that while the suspension addressed driver difficulties, slow-moving heavy vehicles still posed accident risks. Consequently, police requested the installation of warning signs and lights at accident-prone “black spots.” By November 2026, road authorities moved to remove 30 km/h minimum speed limit signs at the Phan Thiet - Dau Giay expressway toll plaza in Dong Nai province. This action followed an inspection by Road Management Area IV, the Traffic Police Department, and the Vietnam Expressway Technical Service Joint Stock Company (VEC) to ensure signage better aligned with actual traffic conditions. ## Timeline ### 2026-11-01: Vietnam road authorities remove minimum speed signs on highway Vietnam's Road Management Area IV has removed 30 km/h minimum speed signs at the Phan Thiet - Dau Giay expressway toll plaza following driver complaints. 2 sources. https://clstr.news/cluster/vietnam-road-authorities-remove-minimum-speed-signs-on-highway ### 2026-10-09: Vietnam Traffic Police suspend minimum speed penalties on highway inclines Vietnam's Traffic Police have suspended penalties for vehicles traveling below minimum speeds on steep highway sections to conduct a safety and terrain assessment. 6 sources. https://clstr.news/cluster/vietnam-traffic-police-suspend-minimum-speed-penalties-on-highway-inclines --- Cite as: Vietnam highway minimum speed limit adjustments.
