Jersey barriers, also known as concrete traffic barriers, are commonly used to prevent vehicles from crossing the median or entering prohibited areas on highways. However, there are a variety of different names used for these barriers depending on the location and use. In some areas, they are called K-rails, F-shields, or median barriers. The term "new jersey barrier" is used more specifically in the Northeastern United States. Additionally, they may also be referred to as weigh station barriers, construction barriers, or temporary barriers. Whatever the name, these barriers play a crucial role in maintaining safety on highways and preventing accidents.
