What is the end of a guardrail called?

Guardrails play a vital role in ensuring road safety by preventing vehicles from veering off the road or colliding with obstacles. They are designed to absorb the impact of a crash and redirect the vehicle back onto the road. As you drive along highways, you may have noticed the distinct structure of guardrails along the edges, but have you ever wondered what the end of a guardrail is called? In this article, we will explore the answer to this question and dive deeper into the importance of guardrail design and the various components that make up a guardrail system.

The Importance of Guardrails.

Before we move on to the specific terminology regarding the end of a guardrail, let's first understand the importance of guardrails in general. Guardrails are installed to provide safety to drivers by preventing vehicles from leaving the roadway, especially in areas where the risk of a severe crash or falling off a cliff is high. The primary purpose of a guardrail is to redirect the vehicle back onto the road and absorb the impact of a collision, reducing the severity of injuries and damages.

The End Terminal.

Now, turning our attention to the end of a guardrail, it is called an end terminal. An end terminal is a specially designed device that is installed at the end of a guardrail system to enhance its performance and improve safety. The purpose of the end terminal is to reduce the severity of impact forces when a vehicle crashes into the end of the guardrail.

End terminals are designed to absorb the impact energy by providing a cushioning effect. They consist of energy-absorbing components such as specially engineered steel beams, breakaway cable anchors, and plastic energy absorbers. These components are strategically designed to deform and absorb the energy of a collision, minimizing the risk of the guardrail penetrating the vehicle and reducing the chances of injury or fatality.

Different Types of End Terminals.

There are several different types of end terminals used in guardrail systems, each with its own design features and capabilities. Some of the common types include:

1. Impact Head Terminal: This type of end terminal features a crushable head that collapses upon impact, absorbing the crash energy.

2. Flared End Terminal: Flared end terminals are designed to redirect errant vehicles back onto the road by gradually reorienting them.

3. Energy-Absorbing Panel Terminal: This type of end terminal utilizes a series of interchangeable energy-absorbing panels that deform upon impact, providing cushioning and absorbing energy.

Closing Remarks.

In conclusion, guardrails and their end terminals are crucial components of road safety infrastructure. The end of a guardrail is known as an end terminal, which plays a significant role in enhancing the performance of the guardrail system and reducing the severity of crashes. With their energy-absorbing capabilities, end terminals contribute to reducing injuries and fatalities by cushioning the impact forces during collisions.
