Passive Safety of Roadside Furniture

Passive safety standards for roadside furniture aim to minimise the severity of injuries to vehicle occupants in the event of a collision.

Roadside furniture includes items such as signposts, lighting columns, and traffic signal poles. Passive safety design ensures that these elements are either deformable, breakaway, or yielding upon impact, absorbing energy and reducing the forces exerted on the vehicle and its occupants. This approach significantly lowers the risk of serious injury or fatality in run-off-road incidents, contributing to overall road safety.
