What are the three types of frangible supports?

The three types of frangible supports are categorized into low-impact resistant, frangible, and semi-frangible supports. Frangible supports are designed to break away or collapse under certain pressures or impacts, minimizing damage to vehicles and reducing the risk of injury to occupants.

Low-impact resistant supports are designed to withstand minor impacts without breaking, while still providing safety features when subjected to more significant forces. Frangible supports will break upon impact to reduce risk and injury, while semi-frangible supports might allow for some deformation before breaking, enhancing safety in various scenarios.

This classification is crucial for understanding the different levels of support resistance and how they can mitigate the hazards on the road or in various environments where safety is a priority.
