Which colors are typically used for warning signs in construction zones?

Warning signs in construction zones are typically colored orange and black. This color combination serves a crucial purpose: orange is highly visible and draws attention, signaling caution and alertness to drivers. The black lettering or symbols on these signs provides clear, contrasting information to convey specific warnings related to roadwork, detours, or other temporary hazards that may affect traffic flow or driver safety.

In the context of traffic management, using orange for construction alerts helps differentiate these situations from other types of signs, such as regulatory signs, which often use red and white, or informational signs that might utilize green or blue. The distinctive use of orange and black is recognized universally, helping to ensure that drivers are aware of and can respond appropriately to changing conditions on the roadway.
