Where should the warning signs for hazardous material vehicles be placed?

Warning signs for hazardous material vehicles should be hung at the triangular beacon light positioned at the front center of the top surface of the driver's cab. The identification plate must be fixed on the right side of the vehicle's rear, corresponding to the license plate, and should not be randomly hung or placed inside the driver's cab. Warning label specifications: For tanker vehicles, the words "Hazardous Material" (large red reflective font) should be painted in the center of the upper part of the color bands on both sides of the tank. The font should be bold, with a minimum height of 250mm. For vehicles transporting flammable and explosive hazardous materials, the words "No Open Flame" (large red reflective font) should be painted in the center above the color bands on both sides of the tank, also in bold font with a minimum height of 250mm. Purpose of warning labels: They alert drivers in advance to drive carefully and pay attention to yielding.
As someone who has driven transport trucks for over a decade, I believe the placement of warning signs on hazardous materials vehicles is crucial. Back when I transported chemicals, I always hung them on the upper outside of the front windshield and the center of the rear bumper, sometimes also sticking them on the side doors. This way, other drivers or pedestrians could spot them from afar while on the road, avoiding collisions or accidental entry into restricted zones. If the signs are hung off-center or obscured, accidents can easily happen. I've even seen cases where someone forgot to check, resulting in a ticket from the police. Thinking back now, this is no small matter—it's about lives. We should always pay attention to the cleanliness and stability of the signs, making sure they don't get blown or washed away by wind and rain.
