A national model for Graduated Driver Licensing Programs has existed since the mid 1990s. The model provides guidelines for states to create their own GDL programs. Currently, no state follows all the guidelines, and GDL programs vary widely from state to state.
The recommended guidelines are:
Stage 1: Learner’s Permit
Stage 2: Intermediate (Provisional) License
Stage 3: Full Licensure

To understand the range of differences among states, let’s examine the GDL laws of four states: California, Florida, Mississippi, and North Dakota.
The NHTSA recommends that the state sets the minimum age for a learner’s permit at no younger than age 16. In California, the minimum age for a learner’s permit is 15 years, six months; in Florida and Mississippi, the minimum age is 15. The minimum age in North Dakota is 14.
Before getting a license or restricted license in Florida, new drivers must have a mandatory holding period of the learner’s license of twelve months; the other three states require six months. In Mississippi, license applicants age 17 and older are exempt from the holding period. The NHTSA recommends an intermediate (provisional) stage with a minimum age of 16.5. The applicant must remain crash and conviction free for at least six months to advance from the learner’s permit to the intermediate level. They further recommend that in the intermediate license stage, the applicant must remain crash and conviction free for at least 12 consecutive months to advance to full licensure.
The NHTSA recommends parental certification of 30 to 50 practice hours of driving in the learner’s permit stage. While California and Florida each require 50 hours, 10 of which must be at night, neither Mississippi nor North Dakota require certification of any driving practice hours.
Applicants in Mississippi must be age 15 years, six months before getting a license or restricted license. Florida, North Dakota, and California require a minimum age of 16; however, in California, license applicants who do not take driver education must wait until age 18 for a license. The NHTSA recommendation is for full licensure only after completion of the intermediate licensing stage, with a minimum age of 18 for lifting passenger and nighttime restrictions. However, North Dakota does not have any passenger or nighttime restrictions, and Florida and Mississippi have only nighttime restrictions. California’s passenger restriction is that for the first 12 months, the restricted driver may have no passengers younger than 20, with limited exceptions for immediate family.
One way to improve the traffic crash figures for teenage drivers is to advocate for stronger Graduated Driver Licensing requirements in your state. In the meantime, you can reduce the risks for your own children by ensuring that they obey existing GDL laws and by implementing some of the NHTSA’s guidelines into your own house rules if your state has relatively weak GDL laws.
