California Teen Driving Laws: Permits, Curfews and Penalties

California teen driving laws move a young driver through three stages: an instruction permit at 15 years and 6 months, a provisional license at 16 with nighttime and passenger restrictions for the first 12 months, and an unrestricted license at 18. Along the way, the state layers on a total phone ban for drivers under 18, a zero-tolerance alcohol rule for anyone under 21, and personal financial liability for the parent or guardian who signs the application.

Instruction Permit at 15½

A teen can apply for an instruction permit once they turn 15 years and 6 months old, and only after enrolling in or completing an approved driver education program.¹ The application happens in person at a DMV office and requires proof of identity and residency, a signed parent or guardian application, a vision exam, and a written knowledge test on California traffic laws and signs.

With the permit in hand, the teen can only drive when a supervising driver sits in the front passenger seat and can take control of the vehicle. That supervisor must be a California-licensed driver at least 25 years old, unless the person is the teen’s parent, spouse, guardian, or a licensed or certified driving instructor.² A 21-year-old older sibling does not qualify unless they are the teen’s legal guardian.

Six Months of Training Before the Road Test

The permit must be held for at least six months before the teen can schedule the behind-the-wheel driving test.³ During that stretch, the teen must complete three separate requirements:

At least 30 hours of classroom driver education covering traffic laws, safe driving practices, and the effects of alcohol and drugs.²
At least six hours of professional behind-the-wheel training with a DMV-licensed driving instructor.⁴
At least 50 hours of supervised practice driving with a California-licensed driver who is 25 or older (or a parent, guardian, spouse, or instructor), with a minimum of 10 of those hours at night.³

The 50 practice hours are separate from the six hours of professional instruction. A parent, guardian, or instructor certifies the practice hours on the required form.

Provisional License Restrictions in the First 12 Months

After the teen passes the road test at 16 or older, the DMV issues a provisional license. Two restrictions apply for the first 12 months:²

No passengers under 20 in the vehicle unless a qualifying supervising adult (parent, guardian, or someone 25 or older) is also present.
No driving between 11 p.m. and 5 a.m. unless supervised by a parent, guardian, licensed driving instructor, or someone 25 or older.

One enforcement detail: law enforcement cannot pull over a teen driver solely to check whether they are violating these provisional restrictions.² An officer must have a separate lawful reason for the stop, such as a traffic violation or equipment issue. Once the stop happens, the officer can enforce the provisional restrictions.

Exceptions to the Curfew and Passenger Rules

California allows narrow exceptions when the teen has a genuine need to drive and carries documentation, per the California Highway Patrol:⁵

Medical necessity, documented by a signed note from a physician stating the condition and expected recovery date.
Employment necessity, documented by a signed note from the employer.
School-authorized activity, documented by a signed note from a principal, dean, or designee.
Immediate family member need, documented by a signed note from a parent or guardian stating the reason, the family member involved, and the end date.
Emancipated minors, who are exempt from the provisional restrictions altogether.

Each note must include the date the exception ends, and the documentation must stay in the vehicle whenever the teen drives under that exception.³

Total Phone Ban for Drivers Under 18

California prohibits all wireless phone and electronic device use for drivers under 18, including hands-free devices.⁶ That is stricter than the adult rule, which permits hands-free use. For a teen with a provisional license, there is no legal way to talk, text, or use any electronic communication device while driving. The only option is to pull off the road and park before touching the phone.

Zero Tolerance for Alcohol Under 21

California enforces a zero-tolerance standard for any driver under 21. A blood-alcohol concentration of 0.01 percent or higher is illegal, so even a single drink before driving can trigger a violation.⁷ That threshold sits far below the 0.08 percent standard that applies to adult drivers.

If stopped with reasonable cause, the teen is considered to have already consented to a preliminary alcohol screening test. Refusing the test results in a suspension of driving privileges lasting one to three years, even when the teen was not actually impaired.⁷ A zero-tolerance violation also does not shield the teen from a standard DUI charge if the BAC reaches 0.08 percent or higher.

Penalties for Violating the Provisional Rules

Fines and community service scale with repeat offenses:²

First offense: 8 to 16 hours of community service, or a fine of up to $35.
Second or subsequent offense: 16 to 24 hours of community service, or a fine of up to $50.

If the court orders community service and the teen fails to complete it within 90 days, the court converts the sentence to the corresponding fine.²

Points on the Driving Record

Points on the record trigger separate consequences that go beyond the fines above. For a provisional license holder:⁸

Two or more points in 12 months: a 30-day driving restriction requiring the teen to be accompanied by a licensed parent, spouse, guardian, or other driver who is at least 25.
Three or more points in 12 months: a six-month suspension of driving privileges and a one-year probation period, during which the teen must stay free from reportable traffic violations and at-fault accidents.

Points add up faster than parents often expect. A speeding ticket, a red-light violation, and an at-fault accident within a 12-month window can reach the three-point threshold that triggers the suspension.

Parent and Guardian Liability

Two liability rules attach to a teen’s driving. The parent or guardian who signs the license application becomes jointly and severally liable for damages caused by the teen’s negligent driving.⁹ Separately, any parent or guardian who gives a minor express or implied permission to drive is jointly liable for the teen’s negligent or wrongful acts behind the wheel.¹⁰

In practical terms, if the teen causes a serious accident, the parent is personally on the hook for damages alongside the teen. California requires minimum liability insurance of $30,000 per person and $60,000 per accident for bodily injury, plus $15,000 for property damage. Those minimums may not come close to covering a major injury crash, so families with assets worth protecting typically carry higher limits.

What Changes at 18

The provisional restrictions drop off automatically when the driver turns 18, provided the teen has held the provisional license for at least 12 months and is not currently under suspension or probation. There is no new driving test and no separate application. The license converts to a standard, unrestricted Class C license.²
