Final answer:
Fire engines are being painted yellow-green instead of red for visibility and safety reasons. Yellow-green is highly visible and associated with caution and emergency situations. Research has shown that yellow-green is more effective at reducing accidents compared to red.
Step-by-step explanation:
The reason why more and more fire engines are being painted yellow-green instead of red is due to visibility and safety concerns. The color yellow-green, also known as lime-yellow or fluorescent yellow-green, is highly visible during both daytime and nighttime, making it easier for other drivers to see the fire engine on the road. Additionally, this color is often associated with caution and emergency situations, which helps alert people to the presence of the fire engine.
Furthermore, research has shown that the color yellow-green is more effective at grabbing attention and reducing accidents compared to traditional red. A study conducted by the University of Nebraska-Lincoln found that yellow-green fire engines had significantly fewer accidents compared to red fire engines.
Overall, the shift towards yellow-green paint for fire engines is driven by the goal of enhancing visibility, ensuring the safety of firefighters and other road users, and reducing accidents.
