Accidents in flash ice

Man, there were already several accidents with lightning ice today and the poor drivers were all surprised by the sudden ice. Why, actually, have we already summer? In WInter you always have to reckon with it. Are the drivers actually overwhelmed with all the situations? Do you also have to put up flash ice signs? Or warn people with posters about it? We were between Christmas and shortly before New Year’s Eve times in the resin and with some snow the people are turned down It was e only 20 km/h driven with warning flashers. Can such people not rather stay at home in front of the TV???? Are there only overburdened AUtodrivers left?
