How is a highway shutdown after a pile up?


The most obvious thing is a emergency vehicle would block the highway off with lights but in near 0 visibility situations I still feel like car would go flying into the emergency vehicle and it would just be an everlasting pileup until conditions clear.

The first responders there block right at the problem/crash, and notify the incoming units to close off the roadway at xyz location. Use whatever at your disposal to narrow the incoming traffic to one or two lanes (barrels, cones, roadway management trucks with flashing arrows, emergency lights, etc…), and maybe even to force an exit of that stretch of roadway. Use those overhead electric signs to warn drivers well in advance. Notify all public notification options (AM radio, social media, televised media, etc…), and cross your fingers.
