What can red-white warning plates on vehicles indicate?

The presence of red-white warning plates on vehicles serves to alert other road users to specific traffic situations. In Germany, these plates indicate:

1. A trailer parked on the roadway within a built-up area, which warns that there may be reduced visibility or unexpected obstacles on the road.
2. A vehicle with excessive width, signaling that the vehicle may take up more space than usual, which is important for safe passing and following distances.

These indicators are crucial for maintaining safety on the roads. Recognizing all relevant conditions, as indicated by the warning plates, allows drivers to adjust their behavior accordingly, reducing the risk of accidents. Hence, selecting both options 1 and 2 is essential for understanding the full range of warnings these plates provide.
