School buses in the United States must have a white roof as part of their federal safety standards. The reasoning behind this rule is that a white top will reflect heat away from the bus, keeping the interior cooler and preventing the possibility of a fire. Additionally, a white roof will make the bus more visible to other motorists, helping to avoid accidents.
The inside of a school bus is designed to deal with many children and provide a safe, comfortable environment for learning.
School buses are painted a specific color, such as yellow or orange, on the outside but have white roofs for several reasons. Why do school buses have white roofs?

The History of White School Buses
Most school buses in the United States are white with a yellow or green stripe. But why? It turns out there’s a pretty simple answer.
In the early days of school buses, they were just repurposed by public transportation companies. These buses were usually red, green, or yellow. In 1939, a study was conducted to see if the color of a school bus affected its safety.
The study found that yellow was the most visible color, creating the National School Transportation Specifications and Procedures. These specifications recommended that school buses be painted yellow with a black or green stripe.
However, one problem with this recommendation was that yellow paint was expensive. So, in the 1940s, school districts started painting their buses white with a yellow or green stripe. This was a cheaper option, and it made the buses more visible.
Today, most school buses are white with a yellow or green stripe. But some school districts have started painting their buses other colors, like blue, red, or black.
Here are 5 of the reasons – Why School Buses Have White Roofs
1. Moderate the Temperatures on a Hot Day
The white roof will reflect the excess heat or sunlight when it is hot outside. This is a scientific fact. This will allow the ceiling and walls to stay cool and protect the children from getting burned or dehydrated due to excessive heat outside.
White color is considered a cooling agent, which is why it is used on the roof of most vehicles. The bus’s roof reflects the heat to its source, the sun.
Dark colors absorb heat energy, so you should choose white roofing in hot climates. This benefits the children inside, their teacher, and the bus driver.
2. Maintains a Warm Environment on a Cold Day
White color is a poor conductor of heat, meaning it does not absorb a lot of cold when cold outside. The white roof will stay comfortable on a cold day as the temperature drops.
If a bus were painted or covered with a dark-colored roof, it would stay cool because of its dark color. This would make it harder for the bus driver to maintain passengers’ comfort and safety inside the bus.
3. Improves Visibility by Other Motorists
The white roof makes it easier for other motorists to see and avoid the bus when it is moving. As the sun moves across the sky, the white color of a bus will reflect enough light to make it visible to other drivers.
On the other hand, dark colors absorb the sunlight and cannot reflect enough light to make it easy for motorists to see them. The glare from a car’s dark color roof is 10 times worse than from a white roof.
4. Protects the Interior from Sunlight
The inside of a school bus faces plenty of challenges to provide students with a relaxing, comfortable, and safe environment as they travel to school every day.
Unlike dark-colored roofs, the white roof will not produce too much heat inside the bus. This protects the students from excessive heat or cold. The white top is designed to balance the temperature and maintain a safe environment inside, no matter how hot or cold it is outside.
5. Makes the Bus more visible
Most school buses are white with a stripe of color running down the side. But why? It turns out that there’s a convenient reason for this seemingly odd choice of color.
School buses are mainly white because it makes them more visible. This is especially important when they are picking up or dropping off children, as there is a heightened risk of accidents. The bright color is also helpful in inclement weather, making the bus easier to spot in low visibility.
Interestingly, the color of school buses was not always white. In the early days of school buses, they were painted yellow. However, it was found that white buses were more visible, so the switch was made.
So there you have it! The next time you see a school bus, you’ll know that the choice of color is not just a random one but a practical one meant to keep children safe.
The Aesthetics of White School Buses
Regarding school buses, a few things are pretty much universal. They’re big, they’re yellow, and they have a white roof. But why is that? Is it just an aesthetic choice, or is there a more practical reason?
It turns out there is a reason! White roofs reflect sunlight, which helps keep the bus cooler in the summer. This is important because school buses typically don’t have air conditioning, and it can get pretty hot on those long summer trips!
So there you have it! The next time you see a school bus, you can appreciate the white roof for more than just its aesthetic value. It’s a pretty intelligent design choice that helps keep kids cool and comfortable during the summer months.
The Controversy Surrounding White School Buses
School buses in the United States are typically painted yellow, but some are white. The controversy surrounding white school buses is that some people believe they are less safe than yellow school buses.
There are a few reasons why people believe that white school buses are less safe. One reason is that white school buses are more difficult to see in low-light conditions. This is because white is not as reflective as yellow. Another reason is that white school buses blend in with their surroundings more than yellow buses. This can make it more difficult for drivers to see white buses, especially when stopped.
Despite the controversy, there is no evidence that white school buses are less safe than yellow buses. Some studies have shown that white buses may be safer than yellow buses. One study found that white buses were less likely to be involved in accidents than yellow buses. Another study found that white buses were less likely to be involved in accidents at night.
So, why do some school buses have white roofs? One reason is that white roofs help to keep the inside of the bus cooler. White roofs reflect sunlight rather than absorb it like dark roofs. White roofs can also help to prevent the formation of ice and snow on the roof of the bus.
Despite the controversy, there is no evidence that white school buses are less safe than yellow buses. Some studies have shown that white buses may be safer than yellow buses. So, if you’re ever in doubt about which bus is safer, remember that it’s always better to be safe than sorry.
Conclusion – Why School Buses Have White Roofs
A white roof reflects heat and offers excellent visibility, which makes it a great addition to any school bus. Whether you have a bus with a white top or one covered in dark colors, it is safe and efficient to use.
The white roof of the school bus helps calm children during the summer months when temperatures are high outside and allows them to stay safe inside during winter when it is cold.
