**When was the guardrail invented?**.

### Origin of the Guardrail.

Guardrails, also known as roadside barriers or safety barriers, have been around for over a century. The invention of the guardrail can be traced back to the early 20th century when road safety became a growing concern due to the increasing number of cars on the road.

### Early Development.

The first rudimentary guardrails were made of wood and primarily used to prevent vehicles from veering off the road and into ditches or other obstacles. These early guardrails were not very effective and often failed to provide adequate protection in the event of a crash.

### Evolution of Guardrails.

As technology advanced, so did the design and materials used in guardrails. In the 1960s, steel guardrails became more prevalent due to their durability and ability to absorb impact energy in the event of a crash. These steel guardrails, often filled with sand or another energy-absorbing material, provided increased safety for drivers and passengers.

### Modern Guardrails.

### Conclusion.

In conclusion, the guardrail was invented in the early 20th century as a response to the growing need for road safety measures. Over the years, guardrails have undergone significant improvements in design and materials, leading to increased safety for drivers and passengers. Today, guardrails play a crucial role in preventing accidents and protecting lives on roads and highways around the world.
