Driver's license
The minimum driving age varies between 16 and 18 years of age in different States and Territories. After the minimum age, a graduated licensing scheme operates, with state variations.
Kyleigh's Law
On August 6, 2012 the NJ Supreme Court upheld the decal requirement of Kyleigh's Law, saying that it does not violate the federal Driver's Privacy Protection Act which says that the fact that a driver is under 21 and holds a learner's permit, examination permit, or probationary license can be disclosed. The courts said "the driver's age group constitutes neither 'highly restricted personal information' within the meaning of (the federal law) nor 'personal information' within the meaning of" the federal law. "The young drivers subject to (Kyleigh's Law) have no reasonable expectation of privacy in their age group because a driver's age group can generally be determined by his or her physical appearance, which is routinely exposed to public view."
