The third brake light, also known as the center high mount stop lamp (CHMSL), has become an essential safety feature in modern vehicles. Its importance cannot be overstated, as it plays a critical role in preventing rear-end collisions and ensuring the safety of drivers and passengers on the road. Despite its widespread adoption, many people are unaware of when the third brake light became a mandatory safety feature in vehicles.
Overview
The history of the third brake light dates back to the 1960s, when it was first introduced as an optional feature in some vehicles. However, it wasn’t until the 1980s that the National Highway Traffic Safety Administration (NHTSA) made it a mandatory safety requirement in the United States. In this article, we will delve into the history of the third brake light, explore its evolution, and discuss when it became a mandatory safety feature in vehicles.
A Brief History of the Third Brake Light
Stay tuned as we explore the fascinating story of the third brake light, from its humble beginnings to its widespread adoption as a critical safety feature in modern vehicles.
When Did Third Brake Light Become Mandatory?
The third brake light, also known as the center high mount stop lamp (CHMSL), has become a standard safety feature in modern vehicles. But have you ever wondered when it became mandatory? In this article, we’ll delve into the history of the third brake light and explore when it became a required safety feature in vehicles.
The Early Days of Brake Lights
In the early days of automotive history, brake lights were not a standard feature in vehicles. In fact, the first brake lights were not introduced until the 1920s, and even then, they were not mandatory. It wasn’t until the 1950s and 1960s that brake lights became more widespread, but they were still not a requirement.
In the 1960s, the National Highway Traffic Safety Administration (NHTSA) began to take a closer look at vehicle safety features, including brake lights. At the time, brake lights were typically mounted on the rear of the vehicle, but they were not always visible to other drivers, especially in low-light conditions.
The Introduction of the Third Brake Light
In the 1970s, the NHTSA began to explore the idea of a third brake light, which would be mounted higher on the vehicle and provide an additional visual cue to other drivers. The idea was to reduce the number of rear-end collisions, which were a leading cause of accidents on the road.
In 1974, the NHTSA issued a proposal to require a third brake light on all new vehicles. The proposal was met with resistance from some automakers, who argued that the additional cost of the third brake light would be too burdensome. However, the NHTSA persisted, and in 1986, the third brake light became a mandatory safety feature in the United States. (See Also: What Size Brake Light Bulb Do I Need)
The Benefits of the Third Brake Light
The introduction of the third brake light has had a significant impact on road safety. Studies have shown that the third brake light reduces the risk of rear-end collisions by providing an additional visual cue to other drivers. In fact, a study by the NHTSA found that the third brake light reduces the risk of rear-end collisions by up to 50%.
In addition to reducing the risk of accidents, the third brake light also provides other benefits, including:
- Improved visibility: The third brake light is mounted higher on the vehicle, making it more visible to other drivers, especially in low-light conditions.
- Reduced stopping distance: The third brake light provides an earlier warning to other drivers, allowing them to stop sooner and reducing the risk of accidents.
- Enhanced safety: The third brake light is an additional safety feature that can help prevent accidents, especially in heavy traffic or construction zones.
International Adoption of the Third Brake Light
The United States was not the only country to adopt the third brake light as a mandatory safety feature. Many other countries, including Canada, Australia, and those in the European Union, have also made the third brake light a requirement.
In Canada, the third brake light became mandatory in 1987, just a year after it was introduced in the United States. In Australia, the third brake light was introduced in 1990, and it became mandatory in 1995.
In the European Union, the third brake light was introduced in the 1990s, and it became mandatory in 2001. Today, the third brake light is a standard safety feature in vehicles sold in the EU.
Modern Developments in Brake Light Technology
While the third brake light has become a standard safety feature in modern vehicles, there are still ongoing developments in brake light technology. Today, many vehicles feature advanced brake light systems, including: (See Also: How To Fix Electric Parking Brake Problem Acura Tlx)
- LED brake lights: LED brake lights are brighter and more energy-efficient than traditional incandescent bulbs.
- Adaptive brake lights: Adaptive brake lights adjust their brightness and intensity based on the vehicle’s speed and braking conditions.
- Emergency brake lights: Emergency brake lights flash rapidly to alert other drivers in emergency braking situations.
In addition to these advanced brake light systems, some vehicles also feature advanced safety features, such as automatic emergency braking and lane departure warning systems.
Conclusion
In conclusion, the third brake light became a mandatory safety feature in the United States in 1986, following a proposal by the NHTSA in 1974. The introduction of the third brake light has had a significant impact on road safety, reducing the risk of rear-end collisions by up to 50%. Today, the third brake light is a standard safety feature in vehicles sold around the world, and ongoing developments in brake light technology continue to improve road safety.

Frequently Asked Questions: When Did Third Brake Light Become Mandatory
When did the third brake light become mandatory in the United States?
The third brake light, also known as the Center High Mount Stop Lamp (CHMSL), became mandatory in the United States on September 1, 1986, as a result of the National Highway Traffic Safety Administration (NHTSA) regulation FMVSS 108.
What was the main reason behind making the third brake light mandatory?
The main reason behind making the third brake light mandatory was to reduce the number of rear-end collisions. The CHMSL provides an additional visual warning to following drivers, especially in low-light conditions, and helps to reduce the stopping distance. (See Also: How Much Does A Brake Light Bulb Cost)
Are there any exceptions to the third brake light requirement?
Yes, there are some exceptions to the third brake light requirement. For example, vehicles with a gross vehicle weight rating (GVWR) over 10,001 pounds, such as trucks and buses, are exempt from the CHMSL requirement. Additionally, some classic cars and specialty vehicles may also be exempt.
Can I install a third brake light on my older vehicle that didn’t come with one?
Yes, you can install a third brake light on your older vehicle, but it’s essential to ensure that the installation meets the Federal Motor Carrier Safety Administration (FMCSA) and NHTSA regulations. You should consult with a qualified mechanic or auto electrician to ensure the installation is done correctly and safely.
Are third brake lights required on motorcycles?
No, third brake lights are not required on motorcycles. The CHMSL regulation only applies to passenger vehicles, trucks, and buses. However, many modern motorcycles come equipped with brake lights that are designed to provide increased visibility to following traffic.
