What You'll Learn
Semi-trucks and UV protection
While many drivers believe that they are protected from the sun's UV rays while inside their vehicles, this is not always the case. The sun emits three kinds of UV rays, all of which are invisible: UV-A, UV-B, and UV-C. UV-A rays are the most damaging to the skin and eyes, while UV-B rays are less harmful and UV-C rays are absorbed by the atmosphere.
UV-B rays generally cannot penetrate glass, so truckers who keep their side windows closed while driving are protected from these rays. However, different types of window glass offer varying levels of protection against UV-A rays, which can penetrate windows. Side windows in automobiles are crafted from tempered glass, which lets in about 71% more UV rays than front windshields, leading to a higher occurrence of eye damage on the left side of the face. Tinted windows also do not guarantee protection from UV rays, as some tints offer better UV protection than others.
To protect themselves from UV rays, truckers can use sunshades such as the EcoNour Semi-Truck Sun Shade and the TRUCK N SHADEZ Semi Truck Window Shades, which are designed to fit the windshields and side windows of semi-trucks. These sunshades are made from materials that block UV rays and reduce heat, keeping the truck's interior cooler. They are easy to install and store, and some come with additional features like privacy curtains and adhesive fasteners.
Overall, it is important for truckers to be aware of the risks associated with UV rays and to take the necessary precautions, such as using sunshades, to protect themselves while driving.

Plastic windows and shatter-proofing
While I could not find explicit information on whether semi trucks have plastic windows, I did find some information on the types of windows and tints that are used in semi trucks.
The front and back windows of trucks must be made of laminated glass by federal mandate. Side windows, on the other hand, are made of tempered glass, which is designed to shatter into small, harmless pieces upon impact. To enhance the shatter-proofing of these side windows, a plastic film can be applied, which also provides UV protection. This plastic film can also be used to achieve the required tint for the windows, blocking out sunlight and reducing glare.
The level of tinting on semi-truck windows is regulated by federal law, with a requirement of 70% VLT (Visible Light Transmission). This means that the windows must allow at least 70% of outside light to pass through. Some states may have different regulations, with lower VLT requirements, such as 35% or 20%, which can provide more privacy and a darker appearance.
It is important to note that while tinted windows can offer some protection against UV rays, they do not always provide adequate sun damage protection. Additionally, each type of window glass in trucks offers different levels of protection against UV-A and UV-B rays, with UV-B rays being unable to penetrate glass for the most part. As such, truck drivers are advised to take proper precautions, such as wearing appropriate sunglasses and understanding the level of protection offered by their windows.

Tinted windows and privacy
Tinted windows are a popular choice for many drivers, including semi-truck owners. While some may opt for tinted windows for aesthetic reasons, there are also practical benefits to consider. One of the main advantages of tinted windows is the protection they offer against the sun's ultraviolet (UV) rays. This is particularly important for truck drivers, who are at risk of sun-related health issues due to the amount of time they spend on the road.
UV rays can be divided into three types: UV-A, UV-B, and UV-C. Of these, UV-A rays are the most harmful to the skin and eyes, followed by UV-B rays, while UV-C rays are absorbed by the atmosphere and are not a cause for concern. By tinting their windows, truck drivers can reduce the amount of UV-A and UV-B rays that enter their vehicle, thereby lowering their risk of sun-related health issues.
However, it is important to note that not all tinted windows provide the same level of protection. The effectiveness of tinted windows depends on the type of tinting film used and the VLT (Visible Light Transmission) percentage. In the US, federal law mandates that vehicles, including semi-trucks, must allow a minimum of 70% of light transmission through their windows. This means that the tint cannot be too dark, as it needs to transmit at least 70% of the normal light.
While tinted windows can provide some privacy for drivers, this is not their primary purpose. The main function of tinted windows is to reduce glare and heat from the sun, making the driving experience more comfortable and safer. Tinted windows can also help protect the interior of the vehicle from fading and damage caused by prolonged exposure to sunlight.
In conclusion, tinted windows offer several benefits for semi-truck drivers, including protection from UV rays, reduced glare and heat, and enhanced privacy. However, it is important for drivers to be aware of the legal requirements regarding window tinting and to choose a reputable installer to ensure compliance with federal regulations.

Rear-view visibility
Federal law in the US states that 70% of normal light must be transmitted through tinted windows. This is to ensure that drivers can still see clearly out of their windows and that other drivers can see inside the vehicle, which is important for safety. However, as one semi-truck driver noted, a 5% tint on the rear window can help keep the sun out while still allowing them to see out when needed. A slightly higher tint of 20% is also preferred by some drivers, as it provides a balance between privacy and glare protection.
In addition to tinting, another way to improve rear-view visibility is by utilising the rear-view mirrors. Some semi-trucks have windows at the bottom of the vehicle, which may be there to improve the driver's field of vision when looking through the rear-view mirror. This can be especially useful when the truck is backing up to ensure that it is clear to open the doors.
Finally, while not directly related to the windows, it's worth mentioning that the design of the rear lights can also impact rear-view visibility. For example, some older trucks have doors that can be opened 180 degrees, with the rear lights shining through the glass. This ensures that the lights are visible from a wider range of angles, which is important for safety, especially when stopped in unusual or poorly lit places.

Semi-trucks and glare protection
Sun glare can be a significant problem for semi-truck drivers, and prolonged exposure to the sun's UV rays can lead to various eye problems, including keratoconus and pterygium. While federal mandates require trucks to have laminated glass for the front and back windows, side windows are crafted from tempered glass, which offers less protection and can let in up to 71% more UV rays.
To combat this issue, some semi-trucks are equipped with plastic windows or window films that provide additional UV protection. These plastic films not only enhance UV protection but also make the windows shatter-proof. However, it is important to note that not all semi-trucks have plastic windows, and the level of protection can vary depending on the type of glass and the presence of tinting.
There are also aftermarket products available specifically designed to reduce glare and protect against UV rays for semi-truck drivers. These include visor extenders, such as the Glare Guard Polarized Truck Visor Extender, which can be attached to the existing sun visor to provide additional coverage and block out the sun. While some users have found these extenders effective in reducing glare, others have mentioned that they may not be large enough for semi-trucks and that the price is relatively high for the product.
Another option for glare protection in semi-trucks is the use of window sun shades. These shades are designed to fit over the side windows, providing extensive coverage and UV protection. They are easy to install, utilizing a sturdy suction cup design, and help keep the temperature cool and comfortable while driving.
Overall, semi-truck drivers have several options to enhance their protection against sun glare and UV rays. From plastic windows or films to aftermarket visor extenders and window sun shades, these solutions can help improve visibility, reduce eye strain, and maintain a comfortable driving environment.
