In the United States, the driving age depends on the state and the stage of licensing. You can usually get a supervised learner’s permit between ages 14 and 16, move to a restricted (intermediate) license around 16, and qualify for a full, unrestricted license at 17 or 18. There is no single national driving age because licensing is a state responsibility, but every state uses a phased system that adds privileges as a new driver gains experience.
Why the Driving Age Varies by State
Licensing authority sits with the states under the Tenth Amendment, which reserves to the states powers not granted to the federal government. That is why a 14-year-old can hold a learner’s permit in South Dakota while a teen in another state has to wait until 16.
What the federal government does influence is structure. The National Highway Traffic Safety Administration ties certain highway safety grants to states maintaining a graduated driver licensing system, commonly called GDL. Every state now uses one. A GDL system breaks licensing into three stages: a learner’s permit, an intermediate license with restrictions, and a full license. Each stage has its own minimum age, waiting period, and conditions.
Learner’s Permit: Ages 14 to 16
The earliest permit age in the country is 14, available in a handful of states including Alaska, Arkansas, Iowa, Kansas, North Dakota, and South Dakota. Most states set the floor at 15 or 16.1Insurance Institute for Highway Safety. Graduated Licensing Laws
A permit does not let you drive on your own. A licensed adult, almost always at least 21, has to sit in the front passenger seat whenever you are behind the wheel.
To apply, you’ll generally need:
- Proof of identity, such as a birth certificate or passport
- Proof of your Social Security number
- One or two documents showing your home address
- A parent or guardian’s signed consent, which some states require to be notarized or witnessed at the licensing office
Permit fees run roughly $10 to $35 depending on the state.
Most states make you hold the permit for at least six months before you can move up, and some require as long as twelve.1Insurance Institute for Highway Safety. Graduated Licensing Laws During that stretch you need to log supervised practice hours, typically 30 to 70 depending on the state, with a portion (often 10 hours) completed after dark. Many states also require or reward completion of a driver’s education course, sometimes shortening the holding period or practice-hour requirement for students who finish one.
Intermediate (Restricted) License: Around Age 16
After meeting the permit requirements, most drivers move to a restricted license at 16, or in a few states as early as 15.1Insurance Institute for Highway Safety. Graduated Licensing Laws This is the stage where you can drive alone, but with limits that stay in place for months.
Two restrictions appear in nearly every state’s version:
- Nighttime curfew. Driving is usually prohibited from somewhere between 10 p.m. and midnight until 5 or 6 a.m. Standard exceptions cover travel to and from work, school, or medical appointments.
- Passenger cap. Non-family passengers under 21 are typically limited to zero or one for the first several months, then loosened.
Cell Phone Rules for New Drivers
Thirty-six states and the District of Columbia ban all cell phone use by novice drivers, going further than the handheld bans that apply to adults.2Governors Highway Safety Association. Distracted Driving In those states, even hands-free calls are off-limits during the learner or intermediate stage.
What Happens If You Break the Restrictions
A curfew or passenger violation on a restricted license is not treated like an ordinary ticket. Many states respond with a 30- to 90-day suspension or an automatic extension of the restricted stage. Teen drivers also face lower point thresholds for suspension than adults, so two or three violations can push a new driver into a suspension that an adult would not face at the same point count. Reinstatement usually carries its own fee on top of any fine.
Full Unrestricted License: Age 17 or 18
The curfew and passenger limits drop off at the full license stage, which arrives at age 17 in some states and 18 in most.1Insurance Institute for Highway Safety. Graduated Licensing Laws The main prerequisite is holding the intermediate license for a set period, usually six to twelve months, with a clean record. Major moving violations or at-fault crashes can delay eligibility.
The upgrade itself is straightforward. You pay a small fee, and the restrictions come off. You generally do not need to retake tests or resubmit identity documents if your intermediate license is still valid. From that point you are held to the same traffic laws as any other adult driver.
Hardship and Farm Permits for Younger Teens
Some states allow younger drivers on the road when there is a genuine need. Hardship licenses, sometimes called minor restricted licenses, are available in certain states for drivers as young as 14 or 15 who can show a specific need such as a lack of school transportation or a family medical situation. These permits typically limit travel to a direct route between home and the approved destination, cap mileage, and restrict driving to daylight hours. Recreational driving is not covered.
Agricultural permits go younger still in a few places. Nebraska issues temporary farm permits to youth as young as 13 with a parent or guardian’s signature, and Wisconsin allows farm machinery operation on highways starting at age 12 after completion of a tractor safety course.3Centers for Disease Control and Prevention. A Summary of State Laws Regulating Youth Operating Farm Equipment Farm permits are narrowly drawn to agricultural work. Using one for anything else can trigger immediate revocation and delay qualifying for a standard permit.
Zero Tolerance for Alcohol Under 21
Any young driver should know the alcohol rule separately from the age rules. Under 23 U.S.C. § 161, a state that fails to treat a driver under 21 with a blood alcohol concentration of 0.02 percent or higher as legally intoxicated loses 8 percent of its federal highway funding.4Office of the Law Revision Counsel. 23 USC 161 – Operation of Motor Vehicles by Intoxicated Minors Every state has adopted a zero-tolerance law. Most set the cutoff at 0.02 percent, and a few use a stricter 0.00 percent.
In practice, 0.02 percent means a single drink can put a young driver over the limit. A first offense typically brings a license suspension of 90 days to a full year, plus mandatory fines, community service, or alcohol education in many states.
The Tests You’ll Take
Each stage sits behind a set of tests. The specifics vary, but the sequence is the same across the country.
Vision Screening
Most states require 20/40 visual acuity in at least one eye, with or without corrective lenses. If you need glasses or contacts to pass, your license will carry a corrective-lens restriction, and driving without them becomes a citable offense.
Written Knowledge Test
The written exam covers road signs, right-of-way rules, and basic traffic law. Question counts run from 18 to 50 depending on the state, and passing scores fall between 70 and 88 percent, with 80 percent being the most common cutoff. Every state publishes a free driver’s manual that covers the test material. Some states split the exam into separate signs and rules sections that must each be passed on their own.
Road Skills Test
The road test is where a state examiner, or a certified third-party tester in states that allow it, rides along while you demonstrate turning, lane changes, stopping, and parking. You’ll need a properly insured and registered vehicle, and your supervising adult has to drive you to the test site. Most states let you retry after a short waiting period if you fail, though some charge a retest fee.
What a Teen Driver Costs to Insure
Adding a teenager to a family auto policy runs roughly $2,500 to $3,500 per year on average. The exact figure depends on the teen’s age, gender, vehicle, location, and the family’s claims history. Insurers price teen drivers higher because the crash data justifies it: drivers under 20 are involved in far more accidents per mile driven than any other age group.
Several things can bring premiums down. Good-student discounts, usually requiring a B average or better, are offered by most major carriers. A state-approved driver’s education course qualifies for a discount in many states. Vehicle choice matters too, since a modest sedan is cheaper to insure than a sports car. Teens with a learner’s permit are typically covered under their parent’s existing policy at no extra charge, but the premium bump arrives once an intermediate or full license is issued.
