What is true in relation to yellow road markings?

Yellow road markings in Germany serve specific purposes, primarily in relation to construction zones and temporary traffic regulations.

1. Yellow markings are indeed often used in temporary situations, such as during roadwork, which is why they can be applied at construction sites. This includes guiding vehicles safely through altered traffic patterns.

2. Yellow markings can replace white markings, but this is temporary and generally occurs when the normal traffic flow is disrupted due to construction or other events. In such cases, the yellow markings indicate the new traffic rules that must be followed.

Understanding this combination is essential because it highlights the temporary nature of yellow markings and their role in modifying usual traffic patterns for safety and efficiency during construction or related activities. These regulations ensure that all drivers are aware of changes and can navigate safely through areas affected by roadwork.
