What is the shape and color of warning or temporary condition signs?

Warning or temporary condition signs are designed to alert drivers about changes in road conditions or potential hazards ahead. These signs are typically diamond-shaped and feature a yellow background, which stands out to grab the attention of drivers. The yellow color is used for its visibility and association with caution, thereby effectively communicating the need for increased awareness and potentially reduced speed.

The diamond shape reinforces the concept of warning as it is distinctly recognized by drivers, making it easy to identify even from a distance. This design is part of standard road signage, ensuring consistency across different regions, including Alberta. Understanding these elements helps drivers react appropriately to road conditions and enhances overall safety on the road.
