The main purpose of this legislation is to improve road safety by regulating the brightness of low beam headlights on motor vehicles. The goal is to reduce glare that can impair the vision of other drivers, thereby making highways and two-lane roads safer for everyone. The key provision of the law requires the Secretary of Transportation to create a new rule within one year of the law being enacted. This rule will set a maximum brightness limit for low beam headlights, which will be measured in lumens or another suitable unit of measurement.
