The purpose and objective of this final thesis is to explain the application of passive reliable equipment alongside roadways, specifically focusing on poles. The behaviour of such poles will be explained, types based on the construction materials will be described, as well as the advantages and disadvantages of passive reliable poles. Regarding materials; wooden, steel, aluminium, and composite poles will be discussed, and methods for protecting these materials from harmful influences, corrosion, and such will be explained. The majority of this final thesis will be concentrated on the behaviour of passive reliable poles. Passive reliable poles are designed to be particularly stable and durable to ensure reliability in various conditions. Among them, we distinguish poles that absorb energy and those that do not. The main characteristic that describes passive reliable poles is a lower probability of severe injuries to passengers in a vehicle that has collided with a pole. Poles that do not absorb energy do not have the ability to significantly slow down during a collision with a vehicle but retain their solid structure and often break or fall when exposed to a collision. Poles that absorb energy slow down and stop the vehicle which leads to bending underneath the vehicle.
