California teen driving laws phase in driving privileges in three stages — instruction permit at 15½, provisional license at 16, and full license at 18 — and layer on a nighttime curfew, a ban on young passengers, a total prohibition on phone use, and a near-zero alcohol limit, all enforced with escalating DMV penalties that can delay a teen’s path to an unrestricted license.
The Three License Stages
California issues a minor instruction permit to applicants who are at least 15 years and 6 months old.1California Legislative Information. California Code VEH 12509 A teen with a permit may only drive under the direct supervision of a California-licensed adult who is at least 25 years old and whose license is not on probation.2California Legislative Information. California Code VEH 12814.6
The permit has to be held for at least six months before the teen can apply for a provisional license. During that time, the teen must complete 50 hours of supervised practice (at least 10 of them at night) and 6 hours of professional behind-the-wheel training with a DMV-licensed instructor. Once those requirements are met and the teen passes the DMV driving test, the provisional license is issued.
A provisional license is a real license — the teen can drive alone — but it comes bundled with the restrictions described below. Those restrictions last 12 months or until the teen’s 18th birthday, whichever comes first. At 18, assuming the record is clean, the license converts to standard status automatically.
Curfew and Passenger Limits
For the first 12 months after a provisional license is issued, two rules apply at all times unless the teen is accompanied by a qualifying adult.2California Legislative Information. California Code VEH 12814.6
- No driving between 11 p.m. and 5 a.m.
- No passengers under age 20.
Both restrictions lift when a parent, legal guardian, licensed driver aged 25 or older, or a licensed driving instructor is in the car. A 16-year-old can drive younger siblings home at midnight, but only with one of those adults riding along. Without that adult, both rules are absolute.
Exceptions to the Curfew and Passenger Rules
California recognizes specific situations where a provisional driver may drive during restricted hours or carry young passengers without an accompanying adult. Each exception requires signed documentation that the teen keeps in the car and shows to police if stopped.2California Legislative Information. California Code VEH 12814.6
- Medical necessity, documented by a signed note from the teen’s physician stating the condition and expected end date.
- School or school-authorized activities, documented by a signed statement from the principal, dean, or designated staff member.
- Employment, documented by a signed statement from the employer with a projected end date.
- Family necessity, documented by a signed statement from a parent or guardian explaining why the teen needs to drive and when the need will end.
- Emancipated minors, who are exempt from both restrictions.
Every exception also requires that reasonable transportation alternatives be inadequate. A teen who could ride a bus to work but prefers to drive does not qualify, though in practice enforcement focuses on whether the signed document is present rather than on second-guessing the teen’s options.
Total Ban on Phones and Electronic Devices
Adults in California may use hands-free devices while driving. Drivers under 18 may not use a wireless phone or electronic device for any purpose behind the wheel, even with Bluetooth or voice activation.3California Legislative Information. California Code VEH 23124 The law treats the conversation itself as the distraction for inexperienced drivers.
The only exception is a genuine emergency call to law enforcement, a fire department, a health care provider, or another emergency service. Any other use while the car is moving earns a citation.
Zero Tolerance for Alcohol
Under Vehicle Code 23136, it is illegal for any driver under 21 to operate a vehicle with a blood alcohol concentration of 0.01 percent or higher.4California Legislative Information. California Code VEH 23136 That threshold is low enough that a single sip of wine or certain over-the-counter medications can trigger it. The adult limit of 0.08 percent is eight times higher.
A driver under 21 is deemed to have already consented to a preliminary alcohol screening test. Refusing the test results in an automatic one-year license suspension, or a one-year delay in getting a license for a teen who doesn’t have one yet. Testing at 0.01 percent or above triggers the same one-year suspension through the DMV’s administrative process.5California DMV. Driving Under the Influence
This suspension is purely administrative. The DMV imposes it without any criminal conviction. If the teen’s BAC is high enough to show actual impairment, criminal DUI charges under Vehicle Code 23152 can be filed on top of the administrative action.
Penalties for Breaking the Rules
Curfew and Passenger Violations
A first curfew or passenger violation carries 8 to 16 hours of community service or a fine of up to $35. A second or later violation increases the range to 16 to 24 hours of community service or a fine of up to $50.2California Legislative Information. California Code VEH 12814.6 If the court orders community service and the teen does not complete it within 90 days, the court converts the hours to a fine. The base fine amounts look modest, but California court assessments and surcharges typically push the total far above the stated figure.
Points on a Provisional Record
The heavier consequences come from the DMV’s point system, which it watches closely for provisional drivers.
- Two or more points in 12 months triggers a 30-day restriction. The teen may drive only with a licensed parent, guardian, or adult 25 or older in the car.
- Three or more points in 12 months triggers a six-month license suspension and one year of probation, during which the teen must stay violation-free and accident-free.2California Legislative Information. California Code VEH 12814.6
Any restriction or suspension imposed under these rules continues even if the teen turns 18 before the term ends. A six-month suspension handed down at age 17 years and 9 months still has three months left to run after the birthday.
What Changes at 18
When the teen turns 18, the provisional curfew, the passenger limit, and the under-18 phone ban all drop away. The license converts to standard status without any need to apply for a new card or pay a renewal fee.
Two things do not change at 18. The zero-tolerance alcohol rule continues until the driver’s 21st birthday regardless of license type.4California Legislative Information. California Code VEH 23136 And any unexpired restriction, suspension, or probation term from the provisional period carries through the birthday until it runs out on its own. The clean conversion to a full license only happens for teens who kept their record clean during the provisional year.
