What Are Passive Safety Poles?

Passive safety poles are designed to improve road safety. In the event of a collision between a vehicle and a pole, the pole will absorb part of the impact force.

There are three safety classifications: HE, LE, and NE, which indicate the pole’s approval for different speed zones. For example, a pole with the specification 70-HE is approved for use in areas where vehicles may travel up to 70 km/h.

Each safety class indicates how much a vehicle’s speed is reduced upon impact, whether the vehicle is brought to a complete stop, and which environments the pole is suited for:

• HE Class (High Energy absorption): This class reduces the vehicle’s speed as much as possible, bringing it to a complete stop. It is used in urban areas with many vulnerable road users (pedestrians, cyclists, etc.), minimizing secondary injuries in case of a collision.
• LE Class (Low Energy absorption): This class slows the vehicle to a lesser degree. Poles in this category absorb more of the impact than they slow the vehicle. The vehicle is typically slowed to 0–5 km/h. LE poles are also used in urban areas with many vulnerable road users.
• NE Class (No Energy absorption): This class offers the least reduction in vehicle speed, typically slowing it to between 5–50 km/h. NE poles are used in open areas with few or no vulnerable road users.
