IIHS 2.0 mobile barrier

Mobile barrier according to IIHS regulations, which will be implemented in 2022. The total weight of the previous mobile barrier is increased from 1500 kg to 1900 kg. At the same time, the test speed is increased from 50 kph to 60 kph. Due to the enormous increase in the acting forces during the test, the previous mobile barrier cannot be upgraded in accordance with the new regulation.

To avoid a second impact, the ERNST emergency braking system is mounted on each mobile barrier and effective on all wheels.
