Graduated Driver's License Explained: The 3 Stages for Teens

Parents sometimes tell us the rules feel arbitrary. Why can my daughter drive her little brother to school but not her best friend? Why does the curfew start at 11 p.m. and not midnight? The answer is that every piece of a graduated driver's license system targets a specific way new drivers crash. Once you see the reason behind each rule, they're much easier to enforce at home.

Every state and Washington, D.C. now uses some form of graduated driver licensing (GDL). The details differ, but the shape is the same: three stages, each one adding privileges as the driver builds experience.

What a graduated driver's license is

A GDL system lets new drivers earn full driving privileges in steps instead of all at once. Rather than going from zero to an unrestricted license the day they pass a road test, teens move through:

1. A learner stage, driving only with a supervising adult.
2. An intermediate stage, driving alone but with limits on nighttime driving and passengers.
3. A full license, with no special restrictions.

The logic is simple. Crash risk is highest in the first months of driving alone, and it's driven up by a few specific conditions: darkness, teen passengers, and inexperience with complex situations. GDL holds back exposure to those conditions until the driver has more hours behind the wheel.

Stage 1: learner's permit

What it allows: driving only with a qualified supervisor, usually a licensed adult of at least 21 seated in the front.

How you get it: pass a vision test and a knowledge test, and in some states finish part of driver education first. Minimum ages range from 14 in a few rural states to 16 in states like New York and New Jersey. Our guide on what age you can get your permit has the details.

Typical requirements before moving on:

• A minimum holding period, often six months to a year.
• A set number of supervised practice hours, often 40 to 65, with some at night.
• No recent violations.

The learner stage exists for one reason: practice under supervision is far safer than practice alone. Every hour a teen spends driving with a parent is an hour of experience gained without the risk of solo driving. For the hour requirements by state, see supervised driving hours by state.

Stage 2: intermediate (provisional) license

This is the stage most parents mean when they talk about "GDL rules." States call it an intermediate, provisional, probationary or junior license. The teen can now drive alone, but with two core limits.

Nighttime restriction. No driving during late-night hours unless a parent or qualified adult is in the car. Start times vary from as early as 9 p.m. to midnight. Most states allow exceptions for work, school or religious activities.

Passenger restriction. Limits on how many young passengers can ride along, often zero or one non-family passenger under a certain age, for the first months or the whole stage.

Many states add rules about phone use (often a total ban on handheld and hands-free use for teen drivers), seat belts for every passenger, and stricter penalties for violations.

Stage 3: full license

The final stage removes the special teen restrictions. In many states it arrives automatically at a certain age, commonly 17 or 18, as long as the driver hasn't had serious violations. In others, the intermediate period must last a minimum time and then the driver applies for the upgrade.

Note that a "full" license is not a free pass. Point systems, under-21 alcohol limits and phone laws still apply. And many teens drive more independently after this stage, so the habits formed during stages 1 and 2 carry the load.

Night and passenger limits: why they save lives

These aren't guesses. The Insurance Institute for Highway Safety (IIHS) has studied GDL laws for decades. A few findings worth knowing:

• In a national study of GDL laws from 1996 to 2007, states with laws rated "good" had 30% lower fatal crash rates among 15- to 17-year-olds than states with laws rated "poor."
• The reductions were larger in states that limited teen passengers to zero or one than in states allowing more passengers or none at all.
• Stronger nighttime restrictions were also associated with bigger reductions.
• An earlier IIHS evaluation of California's GDL law found nighttime crash rates of 16-year-olds fell 27% and crashes with teen passengers fell 38%.

Why passengers matter: each additional young passenger increases distraction and peer pressure, from loud music to dares to simple conversation that pulls attention away. Why nights matter: darkness reduces visibility, fatigue sets in, and late-night trips are more likely to involve risky behavior, including impaired drivers on the road.

The Governors Highway Safety Association keeps a state-by-state GDL summary if you want to see where your state's rules land.

How GDL differs in your state

Because states write their own rules, the same family can face different rules after crossing a state line. A few examples of how much variation exists:

• New Jersey applies its GDL program to new drivers under 21 and requires 50 practice hours (10 at night) for permits issued since February 2025. See our New Jersey permit test page for the knowledge test side.
• Maryland requires supervised practice for learners under 25, with fewer hours required at older ages.
• New York sets different junior license rules for upstate, Long Island and New York City.
• Georgia waives its practice-hours requirement for teens who complete a full behind-the-wheel driver education program.

Check your own state's DMV for the exact curfew times, passenger limits and when the restrictions lift.

Parent enforcement tips

The laws only work if they're followed, and most enforcement happens at home, not by police.

• Write a parent-teen driving agreement that mirrors your state's GDL rules and adds your own (no driving after a certain time on school nights, phone in the glove box).
• Be the excuse. Teens often welcome a firm rule they can blame: "My parents will take my keys if I drive more than one friend."
• Keep riding along during the intermediate stage now and then. Skills slip without feedback.
• Lift limits in steps, the way the law does. Add a passenger, then add later curfews, as the driver proves responsible.

Frequently asked questions

What are the three stages of a graduated driver's license?

The learner's permit (supervised driving only), the intermediate or provisional license (solo driving with night and passenger limits), and the full, unrestricted license.

At what age does GDL end?

It depends on the state. Many lift the last restrictions at 17 or 18, while others, like New Jersey, apply some GDL rules to new drivers under 21.

Do GDL rules apply to adults?

In most states GDL is designed for teens, but some extend parts of it to older beginners. Maryland, for example, requires supervised practice for new drivers under 25, and New Jersey has a probationary period for new drivers of any age.

What happens if you break GDL restrictions?

Penalties vary but commonly include fines, points, a longer restricted period, or suspension of the permit or license. Insurance rates can rise too.
