What does this traffic sign combination indicate?

The traffic sign shown is a warning for a rail crossing. It alerts drivers to be cautious as they approach an area where road traffic may intersect with a railway line. This sign is crucial for ensuring the safety of road users, as trains can approach rapidly and are often unable to stop quickly.

According to German traffic regulations, vehicles must yield to trains at these crossings. The presence of this sign means that drivers should reduce speed and be prepared to stop if a train is approaching, indicating the need for increased attention and caution in these areas to prevent accidents. Always look for additional signals such as lights or barriers that may signify an approaching train.
