Road dividers are an important part of road safety. They are used to separate lanes of traffic and can be made of a variety of materials, such as stripes, forks, and highway medians. Stripes are a common type of road divider, consisting of two or more parallel lines painted on the road surface. Forks are another type of road divider, which are usually made of metal and have two prongs that extend from the ground. Highway medians are the most common type of road divider, consisting of a raised barrier in the middle of a highway that separates the two directions of traffic.
