An under-21 license is a driver’s license issued to anyone who hasn’t yet turned 21, printed vertically instead of horizontally so clerks, bartenders, and officers can see at a glance that the holder isn’t of legal age for alcohol or tobacco. Every state and Washington, D.C. now uses this vertical format for drivers under 21, and the card comes with a set of driving restrictions that ease as you move through your state’s graduated licensing system.
What the Card Looks Like
The orientation is the giveaway. Adult licenses are horizontal; yours is vertical. Most states also print “Under 21” or “Under 18” directly on the face of the card, and many add a color-coded header or border as a second visual cue. The layered design means your license does double duty as the ID retailers rely on for age-restricted purchases.
If your state issues REAL ID-compliant licenses, the star marking appears in the upper right corner of the vertical card the same way it does on an adult license. REAL ID enforcement at airport security started on May 7, 2025, so anyone 18 or older now needs either a REAL ID-compliant license, a passport, or another TSA-approved document to board a domestic flight.1Transportation Security Administration. REAL ID A vertical license without the star works for driving but won’t get you through TSA on its own.
The Three Stages of Getting Licensed
Every state runs some version of a graduated driver licensing (GDL) system that moves you through three phases. The strongest GDL programs, with at least a six-month permit holding period, a nighttime restriction starting by 10 p.m., and a limit of no more than one teen passenger, are associated with a 38% reduction in fatal crashes among 16-year-old drivers.2NHTSA. Graduated Driver Licensing
Learner’s Permit
The minimum age for a learner’s permit ranges from 14 in a few states to 16 in others, with 15 being the most common entry point. You can only drive with a fully licensed adult in the passenger seat. States require you to hold the permit for a set period, often six to twelve months, before you can test for the next stage. During this time you have to log supervised driving hours with a parent or other qualifying adult. The required total ranges from 20 to 70 hours depending on the state, with 50 hours (including 10 at night) being the most common requirement.3Insurance Institute for Highway Safety. Graduated Licensing Laws
Provisional License
Pass the road test and you get a provisional license. This is the vertical card most people picture when they hear “under-21 license.” You can drive on your own, but nighttime driving and passenger limits apply and gradually lift over time.
Full License
Once you’ve held the provisional license long enough without violations, the operational restrictions fall away. In many states that happens at 18. The card itself still stays vertical until you turn 21, because the format tracks your age, not your driving privileges. An 18- or 19-year-old can hold a fully unrestricted license on a vertical card.
Documents You Need to Apply
Exact requirements vary by state, but the pattern is consistent. You have to prove who you are, that you live where you say you do, and that a parent or guardian signs off.
- Identity and age: an original or certified birth certificate, or a valid U.S. passport. Hospital-issued certificates and photocopies generally don’t count.
- Social Security number: your Social Security card or other official documentation. The agency verifies the number directly with the Social Security Administration.
- Residency: two documents from different sources showing your name and address, such as utility bills, bank statements, or school enrollment records, typically dated within the last 90 days. For minors, a parent’s documents for the same address usually work.
- Parental consent: a signed form from a parent or legal guardian, available on your state’s DMV website. Many states require the signature to be notarized or witnessed by an agency official.
Bring originals. Photocopies get rejected, and a missing document means another trip.
The Road Test and Fees
Most states let you schedule the road skills test online. When you arrive, a vision screening comes first, so bring glasses or contacts if you wear them. An examiner then checks the vehicle you brought: brake lights, turn signals, horn, tire tread, mirrors, seat belts for both you and the examiner, and a working foot brake. Anything that fails the safety check sends you home to reschedule.
The driving portion covers turns, lane changes, stopping, speed control, and maneuvers like parallel parking and three-point turns. After you pass, the office takes your photo and collects the fee. Licensing fees range from around $10 in the cheapest states to nearly $90 in the most expensive, depending on the state and the length of the license term. You leave with a temporary paper permit that works as your license until the physical card arrives in the mail, usually within two to four weeks.
Restrictions While You Hold a Provisional License
The provisional phase is where the GDL system does its heaviest work, targeting the conditions that are statistically deadliest for teen drivers.
Nighttime Driving
Curfew restrictions typically start somewhere between 9 p.m. and midnight and run until 5 or 6 a.m., though the exact hours vary by state.3Insurance Institute for Highway Safety. Graduated Licensing Laws Most states carve out exceptions for driving to or from work, school activities, or medical emergencies. Some offer hardship licenses when no other transportation is available, with strict route and mileage limits attached.
Passengers
During the early months of a provisional license, you’re generally limited to one non-family passenger under a certain age (usually 18 to 20). Immediate family members are almost always exempt. The limits ease after the first six to twelve months without a violation. Crash risk for teen drivers rises sharply with each additional teen passenger in the car.
Cell Phone Use
Thirty-six states and Washington, D.C. ban all cell phone use by novice drivers, going beyond the texting bans that apply to everyone.4Governors Highway Safety Association. Distracted Driving In those states, even hands-free calls are off limits during the provisional period. Penalties for breaking any of these restrictions can include fines, community service, points on your record, and if violations stack up, an extension of the provisional period or a suspension.
Zero Tolerance for Alcohol
Every state sets the blood alcohol limit for drivers under 21 at 0.02% or lower, well below the 0.08% that applies to adults.5NHTSA. Lower BAC Limits Some states set the line at 0.01% or 0.00%, meaning a single drink, or even trace amounts from mouthwash in the strictest states, can put you over.
A first offense triggers a license suspension that runs anywhere from 30 days to two years, depending on the state. Refusing the breath test usually makes it longer. An underage DUI can also show up on background checks, affect college admissions, and complicate financial aid. Reinstatement fees commonly run $250 to $500 on top of court-imposed fines. One thing worth knowing: even if a court later expunges the conviction, the DMV suspension and the points on your driving record usually stay. The court and the DMV operate independently.
What Insurance Costs
Adding a 16-year-old to a married couple’s auto policy raises the annual premium by roughly $3,200 on average, more than doubling what they were paying. Full-coverage cost for a household with a 16-year-old driver averages around $5,700 per year, and those rates climbed about 14% between 2023 and 2025.
A few discounts can take some edge off:
- Good student discount for maintaining a B average or better, offered by most major insurers.
- Driver’s education credit for completing an approved course, offered by some carriers.
- Distant student discount if your teen goes away to college without a car.
Shop around. Rate differences between insurers for young drivers can be dramatic, and the cheapest quote for one family can be twice as expensive from another company.
Why a Fake ID Is a Bad Trade
The vertical format makes the card an obvious target, and some under-21 drivers try to alter theirs or buy a counterfeit horizontal ID. Depending on the state, possessing or using a fake ID can be charged as a misdemeanor or a felony. Penalties commonly include fines, community service, a criminal record, and a driver’s license suspension of up to a year, even if the fake had nothing to do with driving. Lending your real ID to someone else usually carries similar consequences. For college students, a conviction can trigger academic disciplinary proceedings on top of the legal penalties.
Switching to a Horizontal License at 21
Your vertical license has an expiration date, and in most states it lands on or shortly after your 21st birthday. Some states let you apply for the horizontal replacement online or at a self-service kiosk starting on your birthday. Others require an in-person visit. A few states let you start the renewal up to 30 or 40 days before you turn 21, which prevents any gap between your old card expiring and the new one arriving.
The new horizontal card drops the under-21 visual markers and any remaining age-based restrictions. Keep your old vertical card as backup identification until the physical replacement shows up, even if the agency punches a hole in it.
Don’t put the switch off. Driving on an expired license, including one that expired only because you aged out of the vertical format, can get you a citation and fines. And many bars and liquor stores won’t accept a vertical ID from someone claiming to be 21, no matter what the birthdate on it says. The orientation works against you the moment you’re old enough for it not to.
