The rules for a 16-year-old driver in California come from the state’s provisional license program, and they apply for the first 12 months after the license is issued or until the driver turns 18, whichever comes first. During that window, a 16-year-old cannot drive between 11 p.m. and 5 a.m., cannot carry any passenger under 20, and cannot use a cell phone in any mode while driving. A qualifying adult in the car lifts the curfew and passenger rules; documented exceptions cover work, school, medical needs, and immediate family. The phone ban and California’s zero-tolerance alcohol law have no such workarounds.
The Nighttime Curfew
For the first 12 months of a provisional license, a 16-year-old cannot drive between 11 p.m. and 5 a.m. without a supervising driver in the car. The supervisor has to be a parent, a guardian, a certified driving instructor, or a California-licensed driver at least 25 years old.1State of California Department of Motor Vehicles.

Who Can Ride Along
During those same 12 months, a 16-year-old cannot carry any passenger under age 20 unless one of the qualifying supervisors is also in the car.1State of California Department of Motor Vehicles. California Driver’s Handbook – Getting an Instruction Permit and Driver’s License – Section: Minor’s Restrictions and Exceptions This is the rule that reshapes daily life the most. No driving a younger sibling to practice, no picking up friends for school, no piling into one car after a game, unless an adult meeting the criteria comes along.
Provisional drivers also cannot drive for pay or operate any vehicle that requires a commercial license.1State of California Department of Motor Vehicles. California Driver’s Handbook – Getting an Instruction Permit and Driver’s License – Section: Minor’s Restrictions and Exceptions
Exceptions That Require a Signed Note
California allows four exceptions to both the curfew and the passenger rule. Each one requires written documentation the teen has to keep in the vehicle, and each note must state a date when the exception will no longer be needed.2California Highway Patrol.

- Employment, with a signed note from the employer.
- School or school-authorized activities, with a signed note from a principal, dean, or designee.
- Medical necessity, with a signed note from a physician stating the condition and expected recovery date.
- Transporting an immediate family member, with a signed note from a parent or guardian explaining the reason, naming the family member, and stating when the need will end.
The family member exception is broader than many parents assume; it is not limited to siblings, but it does require the note to spell out the specific circumstances.1State of California Department of Motor Vehicles.

No Cell Phone Use, in Any Mode
Adult drivers in California can talk on a phone in hands-free mode. Drivers under 18 cannot. A provisional license holder is banned from all cell phone use behind the wheel, including hands-free calls, Bluetooth, and speaker mode.3Office of Traffic Safety. Distracted Driving The only exception is contacting 911 or another emergency service. This total ban stays in effect until the driver turns 18, even if the 12-month provisional period ends first.
Zero Tolerance for Alcohol
California’s zero-tolerance law sets the blood alcohol limit for anyone under 21 at 0.01 percent, which covers essentially any detectable amount.4California Legislative Information. California Vehicle Code VEH 23136 A stop triggers an immediate preliminary alcohol screening test, and refusing that test carries its own penalty of a one-to-three-year license suspension or revocation.
A first violation at or above 0.01 percent is an infraction, with fines of $70 to $100 and a one-year license suspension.5Court System of California. The Zero Tolerance Law A BAC of 0.05 percent or higher can be prosecuted criminally, and a license suspension in that range can extend to age 21. The zero-tolerance rule stays in place until the driver turns 21, well after other provisional restrictions have lifted.
Penalties for Breaking the Provisional Rules
Curfew and passenger violations carry relatively light first-offense penalties: 8 to 16 hours of community service or a fine of up to $35. A second or later violation rises to 16 to 24 hours of community service or a fine of up to $50. If a teen ordered to do community service does not finish it within 90 days, the court converts it to a fine.6California Legislative Information. California Code Vehicle Code 12814.6
The bigger risk is the point system. Any traffic conviction adds points to the record, and the thresholds for a provisional driver are tight. Two or more points within 12 months triggers a 30-day restriction during which the teen can drive only with a licensed parent, guardian, spouse, or driver at least 25 years old in the vehicle. Three or more points in 12 months produces a six-month license suspension and a full year of probation, with no reportable violations and no at-fault accidents allowed during that year.6California Legislative Information. California Code Vehicle Code 12814.6
Insurance is the third layer. Moving violations on a teen’s record commonly push premiums up by 20 percent or more, and insurers typically review the last three to five years of history when setting rates.
When the Restrictions Come Off
The nighttime curfew and the passenger rule expire once the teen has held the provisional license for 12 months or turns 18, whichever comes first.7State of California Department of Motor Vehicles. Teen Driver Roadmap The license then becomes a standard, unrestricted California driver’s license if the record is in good standing. The total cell phone ban also lifts at 18, though the adult prohibition on handheld phone use still applies.3Office of Traffic Safety. Distracted Driving The zero-tolerance alcohol rule remains in place until age 21.
What the Parent Signature Means
When a parent or guardian signs a 16-year-old’s license application, they take on joint legal responsibility for damage the teen causes while driving. California law makes the signer jointly and severally liable with the minor for injuries or property damage arising from the teen’s negligent driving.8Justia. California Vehicle Code 17700-17714 – Civil Liability of Persons Signing License Applications Even without the signature, a parent or guardian who lets the teen drive picks up the same liability. The statutory caps on the signer’s exposure are $15,000 per person for injury or death, $30,000 total per accident, and $5,000 for property damage.
Those caps sit below California’s minimum auto insurance requirements of $30,000 per person, $60,000 per accident, and $15,000 for property damage.9State of California Department of Motor Vehicles. Insurance Requirements A serious crash can exceed all of these figures, and families adding a teen driver often carry coverage well above the state minimums for that reason.
