Drizzle and fog also enveloped the capital city of Hanoi at night and early morning, causing cold weather conditions.
Dense layers of fog have made National Highway No.6 from the capital city of Hanoi to the Northwestern provinces through Son La and Hoa Binh slippery, reducing visibility in several areas, affecting traffic and forcing vehicles to move slowly.
All vehicles are instructed to reduce speed when traveling through Van Ho District and Moc Chau Town in Son La Province to avoid accidents.
Thick fog has also covered National Highway No.6 through Mai Chau and Tan Lac districts in Hoa Binh Province, especially in the area of Thung Khe mountain pass, causing low visibility.
The Hoa Binh Provincial Police have required drivers to strictly comply with the Road Traffic Law and follow safe driving regulations, especially when traveling through steep, narrow and winding mountain passes.
The National Center for Hydrological and Meteorological Forecasting reported that by the afternoon of February 7, an extreme cold wave has affected the entire Northwestern and North Central regions.
