Signs that are colored orange are:
Work zone signs.
Regulatory signs.
School zone signs.
Guide signs.
The Correct Answer and Explanation is :
The correct answer is Work zone signs.
Explanation:
Orange-colored signs are primarily used for work zone signs, which are part of traffic control devices designed to alert drivers about temporary conditions that are usually the result of construction, maintenance, or other types of roadwork. These signs are a critical aspect of road safety, as they signal changes in traffic patterns and potential hazards in areas where roadwork is taking place.
Why orange?
Orange is chosen for work zone signs because it is highly visible and stands out against most natural and urban backdrops. This color grabs attention, especially in low-light conditions or when drivers are distracted. It is universally associated with caution, making it an effective choice for indicating a need for drivers to slow down, be vigilant, and follow alternate routes when required.
Types of Work Zone Signs:
- Warning signs: These might indicate the presence of workers on or near the roadway, lane closures, or detours. For example, a “Flagger Ahead” sign warns of workers managing traffic flow.
- Regulatory signs: Sometimes, these signs are used in work zones to indicate speed limits or other traffic regulations. Speed limits may be reduced in these zones, and a “Speed Limit 25” sign might be displayed in orange to make it more visible.
In contrast:
- Regulatory signs are typically white or black and indicate laws or regulations that must be followed, such as speed limits or stop signs.
- School zone signs are often yellow or green, signaling the presence of children in school areas and alerting drivers to slow down.
- Guide signs are usually green, providing directional information such as highway exit signs or mile markers.
Work zone signs are especially important because they help prevent accidents in areas with changing conditions due to construction or maintenance. They promote safety by encouraging drivers to be cautious and mindful of their surroundings while traveling through these zones.
