Snøskred registrert av radaren ved Pollfjelltunnelen 19. mai 2021.

Approximately 150 meters of avalanche exposed road is protected by the system. When an avalanche is detected at the top of Pollfjellet the road is closed. If the avalanche stops before reaching the road, the barriers will reopen, but if the avalanche hits the road, the barriers remain closed and the Road Traffic Control Center (VTS) is notified.

The entire process happens automatically.
