What does the road sign 20t mean?
1 Answers
The road sign 20t indicates a weight limit, meaning the maximum allowable weight for passing vehicles should not exceed 20 tons. During road construction, due to material limitations, regional constraints (such as saline-alkali land or wetlands), and environmental factors (like downhill slopes or tunnels), it is necessary to restrict vehicle weight and speed. This serves both to protect the road infrastructure and ensure the safety of vehicles and passengers. Additional information: 1. Road traffic signs: These are signs installed by most countries to warn, prohibit, restrict, or guide road users. They are typically made with surface materials like stainless steel mirror or brushed panels, titanium plates, glass, acrylic boards, copper plates, aluminum plates, cold-rolled steel, marble, stainless steel pipes, or solid wood. The internal structure uses stainless steel pipes and ferrous metal profiles as reinforcement materials, with light sources such as LEDs, plasma lamps, neon lights, or light guide plates. 2. General road guide signs often have a blue background: They come in square, rectangular, or arrow shapes. Highway guide signs usually feature a green background. Prohibition signs mostly have a red circle with a diagonal slash, indicating restrictions or prohibitions on vehicle or pedestrian traffic behavior. Road markings primarily depict road shapes and are mostly gray in color.
