In addition, a good guard rail can keep the fast-moving vehicle upright, while also stopping its motion. This may vary depending on the direction where the vehicle is coming from, and the speed at which it was going.
Generally, there are many types of guard rails. Arranged from the weakest and the cheapest to the strongest and the most expensive, the types are cable, wood, steel and wood, steel box beam, and concrete barriers. The cheapest type is also the simplest one. Typically, they can be destroyed when a small vehicle would crash into it. However, repair is simple and inexpensive. The simpler types are more commonly used in rural areas with lighter traffic. On the other hand, the stronger ones such as those made from steel and metal offer more resistance against impacts from heavy and fast-moving vehicles.
