I don't know what happens in Germany, but in Spain the media can be sensationalist about the issue sometimes, but official notices usually don't. They are based on warning colors (yellow, orange, red and special red) when the warning is red there are always problems, not always deaths, but serious traffic problems and property damage at least.
It is true that on some occasions they have made mistakes with warnings that later did not amount to that much and this led to public debate, but these are specific occasions, most of the time when they usually warn they get messed up.
Yesterday the notice was special red
