What color are warning signs typically?

Warning signs are typically yellow because this color is universally recognized as a caution signal. Yellow is used to alert drivers to potential hazards or changes in driving conditions, making it essential for safety on the road. It draws attention and is associated with caution, which is vital for ensuring that drivers remain vigilant when approaching situations that may require extra care.

Red is primarily reserved for stop signs and prohibitory or regulatory signs, while green is used for guide signs indicating directions and distances. Blue is often associated with service signs, providing information about services available to travelers. Thus, yellow's connection to warning signs helps reinforce the message that caution is needed in certain areas or under specific conditions.
