What Does DRL Mean In A Car?
DRL is an acronym for ‘daytime running lights.’ Daytime running lights are a safety measure to make your vehicle more visible in traffic. They are especially significant in low light situations, for instance, driving through a tunnel, under bridges, or at dusk or dawn. Your daytime running lights are there to keep you from getting into an accident.
The DRLs are not there to help you see where you are going. They are there to help other drivers see you. When functioning normally, they will activate when your ignition is turned on. Generally, when your headlamps are activated, the daytime running lights will emit dimmer light. They are brighter when your headlamps are off.
Daytime running lights first became mandated in Scandinavia. During the winter months, it stays dark most of the time in the Scandinavian countries, and daytime running lights made sense. The safety benefits are far more significant there than in the U.S. They still have safety benefits in the States, but there is no substantial decrease in accidents. However, some studies suggest that DRLs for motorcycles do positively affect motorcycle traffic safety ratings.
There have been safety concerns with high power running lights. The U.S. Department of Transportation receives thousands of complaints about glare. Motorcycle safety experts claim putting DRLs on cars and trucks reduces the efficacy of running lights on motorcycles. The biggest complaint about DRLs is the high-intensity glare experienced by other drivers. The debate is ongoing.
