Final answer:
Option (a), Work zones or construction zones are typically identified to drivers by yellow signs and cones. These elements are used for alerting and directing the drivers in this area for safety purposes.
Explanation:
In general, construction or work zones are identified to drivers primarily through visual cues, commonly yellow in color. Therefore, the answer is a) Work zones are identified by yellow signs and cones.
These are standardized visuals designed to grab the attention of motorists. The use of yellow is purposeful because it is a color that is highly visible, even under low light conditions, and it signifies caution.
The reason for using signs and cones is to indicate a change in normal traffic conditions.
This allows drivers to be prepared for alterations in the road's layout, a reduction in speed limit, or the presence of construction workers and machinery. It's important that drivers pay careful attention to these signs to ensure their own safety and the safety of workers in the area.
