Final answer:
The question is about the GDL sticker requirement for new drivers. These are reflective decals that must be displayed on a vehicle operated by a novice driver. They help others identify the vehicle as being driven by a newer driver.
Step-by-step explanation:
The question refers to the requirement in some jurisdictions for new drivers to display Graduated Driver Licensing (GDL) decals on their vehicles. The GDL program is a system that is designed to gradually introduce new drivers to the road by providing them with more driving privileges as they gain experience and maturity. These decals are usually reflective and must be visible on the vehicle. They help law enforcement and other drivers identify the vehicle as being operated by a novice driver, which can sometimes lead to more patience and caution from other drivers as well as specific legal considerations from law enforcement. In New Jersey, for example, drivers under the age of 21 who possess a permit or a probationary license must display a red, reflective decal on the top left corner of both the front and rear license plates of their vehicles.
