Supplementary warning symbols on speed limit signs

WARNING: This page does not describe the selected car, but rather 7 other vehicles, including the 2017 BMW X3, 2016 BMW X3, 2015 BMW X3, 2014 BMW X3, and 2013 BMW X3. However, it is still accessible from the selected car via links, so may be relevant.

The only supplementary warning symbols that the system can recognize and interpret are those for wet roads, rain, snow and lorries. Other supplementary warning symbols are not recognized. The speed limit is displayed without any indication of a supplementary symbol. The supplementary warning symbol for wet roads appears only when the windscreen wipers are in operation. Speed limits that only apply at specific times of day are identified based on data from the GPS navigation system.
