Warning sign S5 provides a warning about what?

Warning sign S5 is specifically designed to alert drivers about the presence of a low water bridge ahead. This type of sign serves an important purpose, as low water bridges can become unsafe during periods of heavy rain or flooding when water levels may rise unexpectedly. The warning allows drivers to exercise caution and be prepared for changing conditions, ensuring their safety as they approach the bridge.

Understanding this warning is crucial for maintaining safe driving practices, as failing to heed the sign could lead to vehicle damage or accidents if a driver attempts to cross the bridge when water levels are dangerously high.
