When it comes to vehicle safety, one often overlooked but crucial aspect is the brake light system. A properly functioning brake light system is essential to alert other drivers on the road of your intentions to slow down or come to a halt, thereby preventing accidents and ensuring a safe driving experience. Among the various components of the brake light system, the third brake light, also known as the center high mount stop lamp (CHMSL), has sparked debate among car enthusiasts and owners alike.
Overview of the Third Brake Light
The third brake light, typically mounted on the rear window or trunk lid of a vehicle, serves as an additional visual cue to alert other drivers of your braking intentions. Its importance cannot be overstated, as it provides an extra layer of safety on the road. But the question remains: do you really need a third brake light?
History and Regulations
In the United States, the National Highway Traffic Safety Administration (NHTSA) mandated the use of CHMSLs in all new vehicles starting from 1986. This move was aimed at reducing rear-end collisions, which were a leading cause of accidents on American roads. Since then, the third brake light has become a standard feature in most vehicles.
In this article, we will delve into the importance of the third brake light, explore its benefits, and discuss whether it is indeed necessary to have one. We will also examine the regulations surrounding its use and the potential consequences of not having a functioning third brake light.
Do You Have to Have a 3rd Brake Light?
The third brake light, also known as the center high mount stop lamp (CHMSL), is a safety feature that has been mandatory in many countries, including the United States, since the 1980s. But do you really need to have a 3rd brake light on your vehicle? In this article, we’ll explore the importance of the 3rd brake light, its history, and the laws surrounding it.
History of the 3rd Brake Light
The concept of a third brake light dates back to the 1960s, when car manufacturers began experimenting with additional brake lights to improve safety on the roads. However, it wasn’t until the 1980s that the National Highway Traffic Safety Administration (NHTSA) made it a mandatory feature in the United States.
In 1986, the NHTSA introduced Federal Motor Vehicle Safety Standard (FMVSS) 108, which required all new passenger vehicles to be equipped with a CHMSL. The regulation was implemented to reduce the number of rear-end collisions, which were a leading cause of accidents and fatalities on American roads.

Importance of the 3rd Brake Light
The 3rd brake light serves several purposes that contribute to improved road safety:
- Increased visibility: The CHMSL is mounted higher than the traditional brake lights, making it more visible to other drivers, especially in low-light conditions or when the vehicle is stopped on an incline.
- Reduced rear-end collisions: By providing an additional warning to following drivers, the 3rd brake light helps to reduce the risk of rear-end collisions, which can be fatal.
- Improved safety in heavy traffic: In heavy traffic or stop-and-go conditions, the CHMSL helps to alert other drivers to the vehicle’s stopping intentions, reducing the risk of accidents.
Laws and Regulations Surrounding the 3rd Brake Light
In the United States, the 3rd brake light is a mandatory feature on all new passenger vehicles, including cars, trucks, and vans. The NHTSA regulates the design, performance, and installation of the CHMSL through FMVSS 108.
In Canada, the 3rd brake light is also a mandatory feature, regulated by Transport Canada through the Canada Motor Vehicle Safety Standards (CMVSS).
In other countries, such as Australia and the European Union, the 3rd brake light is not always a mandatory feature, but it is highly recommended as a safety precaution.
Consequences of Not Having a 3rd Brake Light
Failing to equip a vehicle with a 3rd brake light can have serious consequences, including:
- Fines and penalties: In the United States, failing to comply with FMVSS 108 can result in fines and penalties for manufacturers, dealers, and vehicle owners.
- Increased risk of accidents: Without a 3rd brake light, the risk of rear-end collisions increases, which can lead to injuries, fatalities, and property damage.
- Liability in the event of an accident: If an accident occurs and the vehicle is found to be non-compliant with safety regulations, the owner or manufacturer may be held liable for damages and injuries.
Exceptions to the Rule
While the 3rd brake light is a mandatory feature on most passenger vehicles, there are some exceptions: (See Also: What Does Old Brake Fluid Look Like)
- Classic cars: Vehicles manufactured before 1986, when the regulation was introduced, are exempt from the requirement.
- Specialty vehicles: Certain specialty vehicles, such as motorcycles, trailers, and buses, may not be required to have a 3rd brake light.
- Foreign vehicles: Vehicles imported from countries where the 3rd brake light is not a mandatory feature may not be required to have one, but they must still meet other safety standards.
Conclusion
In conclusion, the 3rd brake light is an essential safety feature that has been mandatory in many countries for decades. Its importance cannot be overstated, as it helps to reduce the risk of rear-end collisions and improves road safety. While there are some exceptions to the rule, it is crucial for vehicle owners and manufacturers to comply with safety regulations to ensure the safety of all road users.
Recap of Key Points
The following key points summarize the importance of the 3rd brake light:
- The 3rd brake light is a mandatory feature on most passenger vehicles in the United States and Canada.
- It serves to increase visibility, reduce rear-end collisions, and improve safety in heavy traffic.
- Failing to equip a vehicle with a 3rd brake light can result in fines, penalties, and increased risk of accidents.

By understanding the importance of the 3rd brake light, vehicle owners and manufacturers can take steps to ensure their vehicles are equipped with this essential safety feature, ultimately contributing to a safer and more responsible driving culture.
Frequently Asked Questions About 3rd Brake Lights
Is a 3rd brake light required by law?
In the United States, a 3rd brake light, also known as a center high mount stop lamp (CHMSL), is required by federal law for all vehicles manufactured after 1986. This law was enacted to reduce the number of rear-end collisions by providing an additional visual warning to following drivers.
What is the purpose of a 3rd brake light?
The primary purpose of a 3rd brake light is to provide an additional visual warning to following drivers that the vehicle is stopping or slowing down. This is especially important in heavy traffic or low-light conditions, where a traditional brake light may not be easily visible. The 3rd brake light is typically mounted higher and centered on the rear of the vehicle, making it more noticeable to other drivers. (See Also: Do I Need New Brake Rotors)
