Moin together! The following situation occurred: Snowfall and not completely cleared road with speed limit 100 km/h which was anyway significantly undercut due to the weather – apart from a few cars – anyway. Entry into a tunnel (river underpass, length approx. 3 km) and therefore after approx. 30 meters no snow on the road. New limit 80 km/h. If one is now leaving the tunnel – probably – again snow lie. The stated 80 km/h are indeed regulations, Is there a rule how fast you can get out of the tunnel – maybe even step speed as there might be more snow on the other side? Or for safety reasons only 40 -50 km/h? What is a reasonable speed in this situation? To be honest, I am rather perplexed and ask for suggestions.
