The image shows a red and white sign mounted on a vehicle, likely on a street or road. The text on the sign is in Vietnamese and reads "Khu vực kiểm tra nồng độ cồn." This translates to "Area for alcohol inspection" in English. The sign appears to be part of a traffic control system, possibly for monitoring alcohol levels in vehicles. The background suggests it is taken during nighttime, as the lights from the vehicle and surrounding environment are visible.
