Fluorescent yellow or green signs are typically used for which type of area?

Fluorescent yellow or green signs are primarily used to indicate areas where there is a higher likelihood of pedestrian activity, especially where children are present. This color scheme serves to catch the attention of drivers and alert them to areas that require increased caution. School zones are particularly important because they often have a high volume of foot traffic, especially during drop-off and pick-up times for students. The visibility of these signs enhances safety by ensuring that drivers remain vigilant in these critical areas, helping to protect children as they navigate their surroundings. Other types of areas, such as road construction zones or parks, may use different colors to convey specific hazards or information.
