Children under 5 years old should not be allowed to sled. Only children should sled with their faces forward and up. It is dangerous to sled headfirst. Avoid crowded hills and areas that have obstacles such as trees, fences or rocks. Separate heavier older children from lighter ones. Avoid sledding on busy roads and at night, when visibility can be limited. It is important to properly use the sleds and have appropriate equipment to prevent injury. For children under 12 years old, a helmet should be worn. All children must wear appropriate clothing and footwear.
