What is Graduated Drivers Licensing?
Graduated Drivers Licensing, or GDL, is a three-stage approach to granting young drivers full license privileges. Most states have some form of GDL laws in place. Generally, the three stages of GDL are:

1.	Supervised learning period
	A young driver, after passing a qualifying test, is granted a learner's permit. The new driver is allowed to drive only with a supervising adult in the car for a given period of time or minimum number of hours before earning an intermediate license.
2.	Intermediate license
	At this stage, the driver has earned a license and no longer needs supervision to drive, but is subject to restrictions, such as a curfew, no cell phone, or the number of passengers allowed in the car. Restrictions vary from state to state.
3.	Full-Priviledge license
	The driver meets the age and any other requirements to earn an unrestricted drivers license. Requirements vary from state to state.
4.	Tracking system
	Install a tracking system that alerts police or a monitoring service when the vehicle is reported stolen.

Graduated Drivers Licensing FAQ's

Isn’t 50 hours of supervised driving a lot to ask of teens and parents?

50 hours over six months equals just 8.3 hours per month, or a little more than 2 hours per week. New drivers need time to familiarize themselves with dozens of driving scenarios—for example rural, urban, suburban, freeways, rush hour, nighttime, dusk, rain and snow.

Why target young drivers and not all novice drivers or elderly drivers?

16-year-old drivers have higher crash rates than drivers of any other age, including older teenagers. The very youngest drivers are also more likely to engage in risky behaviors such as speeding and tailgating. The National Institute of Mental Health reports that the part of the brain that weighs risks, makes judgments and controls impulsive behavior is still developing in teens, and does not mature until about age 25. GDL introduces beginners into the driving population in a low-risk manner, protecting them and others.

Why not just penalize the "problem" drivers?

The logic of addressing all young people is that they are all beginners when they start driving. Every novice needs time to develop driving skills in low risk settings.

Does GDL work?

Graduated drivers license (GDL) programs are helping to reduce teen driving deaths. States began enacting GDL laws in the 1990s. Latest data from the National Highway Traffic Safety Administration (NHTSA) indicate the fatality rate for 16 to 20 year old vehicle occupants in motor vehicle crashes per 100,000 population was 27.07 in 2004, down from 27.67 in 2003 and 30.46 in 1994. The 2004 rate was the lowest since record keeping began in 1975.

A study supported by NHTSA, the Centers for Disease Control and Prevention, released in July 2006, found that GDL programs can reduce fatal crashes for 16-year old drivers by an average of 11 percent. Researchers from the Johns Hopkins Bloomberg School of Public Health found that when states had comprehensive GDL programs, those with a least five of the following elements in effect, there was a 20 percent reduction in fatal crashes involving 16-year old drivers:

1.	A minimum age of 15 1/2 for obtaining a learner's permit
2.	A waiting period after obtaining a learner's permit of at least three months before applying for an intermediate license
3.	A minimum of 30 hours of supervised driving
4.	Minimum age of at least 16 years for obtaining an intermediate license
5.	Minimum age of at least 17 years for full licensing
6.	A restriction on carrying passengers.
