Fire Truck From Red To Yellowish Green
- Sep 15, 2017 -

Everyday we know the color of the fire truck seems to have been red, but there are some countries, such as the United States is a yellow fire.

In the 1920s, the American road was dominated by Ford's black cars. Therefore, the fire truck's eye-catching red in the black car in the special obvious. However, this is only one of the many claims about the color of fire engines.

Interestingly, there is a saying that the red is actually the most expensive paint, so when people will fire the car brush red, because it makes people proud of the color! But the truth is so, today we come to talk about the United States fire car color change those things?

It is well known that fire engines are used to cope with fire, rescue emergencies and other professional vehicle equipment. One of the most striking features of fire engines is their strong and bright red. This can make the driver on the road in the identification of fire engines without any difficulties in order to facilitate it to give way.

While red has the longest wavelength in the everyday visible spectrum, which means that it can be found from a distance. This is why the "stop" sign is usually red.

And red in the world of culture symbolizes danger, which highlights the red fire engines in the use of flashing lights and sirens in the case of the importance of the road. Moreover, people are accustomed to seeing the red fire engines.

However, recent studies have confirmed that the human visual system is more sensitive to wavelengths (green yellow) between 510 nm and 570 nm. This is one of the main reasons why all the American school buses are painted yellow.

In addition, the study shows that people in the low light conditions difficult to see the red. If it is night or foggy weather, you are more likely to ignore a red fire truck, rather than a yellow-green fire engine.

A New York optometrist conducted a study on the fire truck road traffic accident, found that the red fire engines as green or yellow fire engines in the evening conspicuous. According to the US Fire Department said 10% of the firefighters were killed in the accident scene.

So then in the mid-seventies of the twentieth century launched the United States to use yellow-green fire engines. Another study to promote the use of yellow emergency vehicles was published in Australia in 1978. Today, Australia's Canberra fire engines are all yellow.

All in all, no matter how environmental lighting conditions, yellow-green emergency vehicles are indeed more likely to find, which is why many countries have changed the fire department of yellow fire engines. So we have reason to believe that the red fire engines may have in the near future will slowly disable!
