Where must you be prepared to encounter sudden fog?

Sudden fog can significantly reduce visibility and create hazardous driving conditions. In Germany, it is essential to be aware of locations where fog is likely to occur. The areas you've selected – near rivers, in marshy areas, and near lakes – are all correct because these environments commonly experience temperature variations and moisture, which can lead to fog formation.

According to German traffic regulations, drivers must be prepared for changing weather conditions and adjust their speed and driving behavior accordingly in these areas. Being aware of potential fog can help prevent accidents and improve safety on the roads. Understanding where to expect fog allows drivers to stay vigilant and to use appropriate measures, such as turning on fog lights when necessary.
