Evolution Of Drl: From Concept To Law

Daytime running lamps (DRLs) are automotive lighting devices that switch on automatically when a vehicle's engine is started. They are designed to make vehicles more visible to other road users and improve safety, particularly in countries with reduced daylight during winter months. While DRLs have been commonplace in vehicles since the 1990s, they were first mandated in Sweden in 1977. Finland, Denmark, Iceland, and Norway followed suit in the subsequent years. In North America, Canada was the first country to require DRLs by law in 1990. In the European Union, DRLs became mandatory for all new cars and small delivery vans in 2011, and for trucks and buses in 2012. However, the United States has not mandated DRLs, and they are only optional in several states.

DRLs were first mandated in Sweden in 1977

In 1977, Sweden became the first country to mandate the use of daytime running lamps (DRLs). This was an expansion of a 1972 mandate in Finland, which required DRLs for people driving in rural, snowy areas during the winter.

Early DRLs in Sweden were known as varselljus, which translates to "perception light" or "notice light". These lights were designed to increase visibility and improve safety on the roads. They were especially useful in the Nordic region, where there is little ambient light during the winter months.

Following Sweden's lead, other Scandinavian countries, including Finland, Norway, Iceland, and Denmark, introduced similar mandates. DRLs became more popular in Northern countries due to the reduced daylight during the winter. Vehicle manufacturers Saab and Volvo were the first to implement DRLs.

DRLs are automotive lighting devices on the front of motor vehicles that automatically switch on when the engine is started. They emit white, yellow, or amber light and are designed to help other road users see an active vehicle. It is important to note that DRLs are not a substitute for headlights or fog lights and are intended to enhance safety by making vehicles more visible during the day.

Other Scandinavian countries soon followed

Following Sweden's implementation of DRLs in 1977, other Scandinavian countries soon followed suit. Finland, which had already mandated DRLs for rural roads in winter since 1972, expanded its DRL requirements to include all roads in 1997. Norway, Iceland, and Denmark also made DRLs mandatory in 1985, 1988, and 1990, respectively. These countries recognised the safety benefits of DRLs, especially in regions with reduced daylight during the winter months.

The adoption of DRLs in Scandinavian countries was influenced by the region's unique ambient light conditions, with darker winters and reduced daylight. This made DRLs particularly effective in enhancing road safety and reducing accidents. The safety benefits of DRLs were first perceived in these countries, and the impact was roughly triple that observed in the brighter United States.

In addition to the Scandinavian countries, Canada also played a significant role in the adoption of DRLs. In 1990, Canada mandated DRLs for all new vehicles, becoming the first North American country to do so. This decision influenced automakers in the United States, with General Motors petitioning the US National Highway Traffic Safety Administration (NHTSA) in 1990 to allow DRLs in US vehicles, similar to Canada. While there was initially mixed public reaction to DRLs in the US, they eventually became commonplace and contributed to road safety.

DRLs are not mandated in the US

While daytime running lamps (DRLs) are commonplace in the US, they are not mandated by law. In 1990, American automaker General Motors (GM) petitioned the US National Highway Traffic Safety Administration (NHTSA) to allow US vehicles to be equipped with DRLs, as was the case in Canada. After several years of mixed reaction from the public and industry, the same types of DRLs allowed in Canada were permitted but not required for the 1995 model year. Since then, automakers in the US market have equipped most of their vehicles with some form of DRLs.

DRLs are automotive lighting devices on the front of motor vehicles that automatically switch on when the engine is running. They are designed to help other road users see your vehicle better, rather than to help drivers see the road or their surroundings better. As such, they are not a substitute for headlights or fog lights and are often made with LED lights instead of halogen bulbs.

In 2001, General Motors petitioned to have the NHTSA mandate the use of DRLs on all US vehicles. However, the petition was denied in 2009, with the NHTSA citing flaws in General Motors' evidentiary studies and data. The NHTSA stated that it remains neutral regarding DRL policy and that there is no definitive data that justifies federal regulation. Despite this, DRLs are still permitted in the US, and automakers can continue to make individual decisions about including them in their vehicles.

While several US states require headlights to be switched on when using windshield wipers, DRLs are not considered headlights in most vehicle codes and therefore do not meet this requirement. The federal government has stated that it will not mandate DRLs, as there is insufficient evidence to prove their effectiveness. However, studies by the NHTSA and the US Department of Health and Human Services have found that DRLs can reduce the involvement of light trucks and vans in daytime crashes by 5.7%. Additionally, DRLs are a cheap and fuel-efficient safety feature, costing the average driver only $3 per year in fuel penalties.

Canada mandated DRLs in 1990

In 1990, Canada mandated that all new vehicles made or imported into the country must have daytime running lights (DRLs). This law, known as the Canada Motor Vehicle Safety Standard 108, came into effect on January 1, 1990, and significantly improved road safety in the country.

DRLs are automotive lighting devices installed on the front of motor vehicles. They automatically switch on when the engine is started and emit white, yellow, or amber light. The purpose of DRLs is not to help drivers see the road or their surroundings better but to make their vehicles more visible to other road users. This is especially beneficial in low-light conditions or poor weather, where it can be challenging to spot vehicles without DRLs.

The implementation of DRLs in Canada was influenced by the earlier adoption of similar regulations in Scandinavian countries, where it is notably darker during the winter months. Sweden was the first country to mandate DRLs in 1977, followed by Finland, Denmark, Iceland, and Norway. Canada recognized the safety benefits of DRLs and followed suit in 1990.

It is important to note that DRLs are not a substitute for headlights or fog lights. While DRLs enhance road safety during the day, drivers should still use their headlights when it is dark or during low-visibility conditions. Additionally, DRLs are not designed to illuminate the road for the driver but rather to make their vehicle more visible to others.

The mandate for DRLs in Canada has had a positive impact on road safety. Studies have shown that DRLs increase vehicle visibility, allowing other drivers to spot vehicles at a greater distance. This, in turn, encourages safer driving behaviors and reduces the risk of accidents. Research by the National Highway Traffic Safety Administration (NHTSA) found that DRLs reduced fatal and non-fatal crashes during the day, as well as collisions involving pedestrians and cyclists.

DRLs are now commonplace in the US

Daytime Running Lamps (DRLs) are now a standard feature on most vehicles in the US, despite not being a legal requirement. They are automotive lighting devices on the front of vehicles that switch on automatically when the engine is running, helping other road users to see your vehicle better.

DRLs are not a substitute for headlights or fog lights, which are designed to illuminate the road ahead. Instead, DRLs are intended to make your vehicle more visible to other drivers, cyclists and pedestrians. They are especially useful in low-light conditions, such as at dawn, dusk, or on overcast days, and can also be beneficial in fog or mist.

The use of DRLs in the US was influenced by their adoption in Canada, where they have been mandatory since 1990. In 1990, American automaker General Motors (GM) petitioned the US National Highway Traffic Safety Administration (NHTSA) to allow US vehicles to be equipped with DRLs. After several years of mixed reaction from the public and industry, DRLs were permitted but not required from the 1995 model year onwards. Since then, automakers in the US market, including Chevrolet, Toyota, Ford and Audi, have equipped most of their vehicles with some form of DRLs.

While DRLs are not mandated by the US government, most new passenger cars, SUVs and light trucks sold in the US now feature them. This is partly due to their proven safety benefits, with studies showing that DRLs can reduce the risk of daytime collisions by up to 15%. Additionally, DRLs have become an opportunity for distinctive styling, with sleek LED strips on the front of vehicles enhancing both safety and aesthetic appeal.

Despite their proven benefits, there are some common misconceptions about DRLs. Some people believe that DRLs are the same as headlights, but DRLs are significantly less bright and are not intended for use in low-light conditions or at night. Another misconception is that DRLs are only useful in northern countries, but studies have shown that DRLs are effective in reducing accidents across various geographical locations and climates.
