What does a sign with a black cross in a yellow diamond alert you to?

A sign featuring a black cross inside a yellow diamond is specifically designed to alert drivers to the presence of cross traffic ahead. This warning serves to notify motorists that they may encounter vehicles or pedestrians intersecting with their path, emphasizing the need for caution. The use of a yellow background signals that a potential hazard exists, prompting drivers to be vigilant and prepared to yield as necessary.

Understanding this sign can help prevent accidents at intersections where visibility may be limited or where traffic patterns are unpredictable. It's important for drivers to interpret these signs correctly to navigate safely and ensure the flow of traffic is maintained without compromising safety for themselves and other road users.
