Warning tiles are slightly heavier than normal tiles, making them easy to spot. They are bigger than other tiles, so if you step on a waning tile, you will notice the difference immediately. Since they are made of slip-resistant material, it is safe to stand on these tiles. You will not get injured because of slipping and falling when you stand on a warning tile. Detectable warning panels help guide visually impaired people easily. These panels help the visually impaired walk or run around the place without colliding with another human being. They make footpaths colorful, though this is not their sole purpose.
