What is the background color of the MERGING TRAFFIC sign?

The Merging Traffic sign is designed to alert drivers that they should be prepared to yield to traffic merging onto their lane. The background color of this sign is yellow, which is a standard color used for cautionary signs. Yellow indicates a warning and signals that drivers need to be alert and prepared to adjust their driving behavior accordingly. The bright yellow color is easily visible and conveys the need for heightened attention, which is critical for safety in areas where traffic is coming together from different directions.

In contrast, red is typically reserved for stop signs and prohibitive messages, green is used for directional signs indicating permitted movements or routes, and blue generally pertains to services and information signage. Therefore, yellow is the most appropriate color for a cautionary sign like Merging Traffic.
