The Role of Guardrails on Highways: More Than Just Safety

Guardrail is one of the important elements in the road safety system, especially on toll roads and high-speed highways. Although often considered as just a lane divider, the role of guardrail is much more complex and crucial in maintaining the safety of road users.

1. Preventing Vehicles from Leaving the Lane
The main function of the guardrail is to prevent vehicles from leaving the road, especially in dangerous areas such as sharp bends, steep inclines/declines, or on the edge of a cliff. When a vehicle hits the guardrail, the impact energy is absorbed and diverted, reducing the risk of a more serious accident.

2. Reducing the Impact of Accidents
Guardrails are designed to control the direction of vehicles during a collision. Instead of rolling over or being thrown off the road, vehicles are directed back to a safe lane. The guardrail structure generally uses flexible but strong steel, so it can absorb impacts and reduce the potential for serious injury to passengers.

3. Restricting Access to Prohibited Areas
Guardrails also function as a barrier between the main road and prohibited areas such as road medians, pedestrian lanes, or emergency facilities. That way, drivers do not carelessly turn or leave the official lane.

4. Provide Visual Guidance
In addition to its physical function, guardrails also provide visual guidance for drivers, especially at night or in bad weather conditions. The surface of the guardrail equipped with reflectors helps improve the visibility of the road boundary.

5. Important for Road Project Safety Standards
In modern road infrastructure projects, the use of guardrails has become a mandatory standard. Its installation is regulated in various technical regulations to suit the type of road, traffic volume, and area risk.
