What are the categories of safety signs and labels?
2 Answers
Safety signs and labels include four categories: prohibition signs, warning signs, mandatory signs, and information signs. Here is a detailed introduction to the categories of safety signs and labels: 1. Warning signs: These signs are intended to warn people of potential dangers. The geometric shape of a warning sign is a black equilateral triangle with a black symbol on a yellow background. 2. Mandatory signs: These signs indicate actions that must be complied with. The geometric shape of a mandatory sign is a circle with a blue background and white graphic symbols. 3. Information signs: These signs indicate the direction of a target. The geometric shape of an information sign is a square with a green or red background, white graphic symbols, and text. 4. Prohibition signs: These signs are meant to stop certain actions. The geometric shape of a prohibition sign is a circle with a diagonal slash, where the circle and the slash are connected in red; the graphic symbol is in black, and the background is white.
After driving trucks for so many years, I've seen plenty of road safety signs and markings. They can generally be divided into several categories: warning signs, like those yellow triangular signs with black borders, alerting you to turns or construction hazards ahead; prohibition signs, those red circles with a slash, such as no parking or no honking; then there are guide signs, blue backgrounds telling you how to navigate or where service areas are; mandatory signs like speed limits or seatbelt stickers; and emergency signs like warning triangles and escape arrows, which are super important during accidents. Paying close attention to these signs can save lives. Always notice their colors and symbols while driving—don't just focus on getting there fast, especially at night or in fog. Taking a moment to read them clearly can prevent many accidents. I've seen many new drivers learn this the hard way.
