Probationary Driver Crash Rates Reduced

In May 2010, New Jersey implemented a law that identified probationary drivers - new drivers between the ages of 16 and 21 - with red decals on their license plates. The law intended to reduce the number of citations and crashes involving these new drivers.

The pre-law period collected crash data from January 2008 to January 2010. The post-law period measured crashes for a year after the law went into effect, ending May 2011. The new decals reduced the number of crashes involving probationary drivers by 9%, saving an estimated 1,624 drivers from a car accident.

The findings from the study suggest the little red decals have had a dramatic effect on reducing crashes among probationary drivers. Results here contribute to the argument for the overall effectiveness of decal laws, providing valuable information for policymakers considering other similar laws across the world.
