California Provisional License Restrictions Explained
When a California driver under 18 passes their behind-the-wheel test, they receive a provisional driver's license — not a full license. The word "provisional" is literally printed on the card. For the first 12 months, two major restrictions apply, with a narrow set of written exceptions. This guide covers the rules exactly as they appear in the California Driver's Handbook, plus the gray areas parents and teens most often get wrong.
The Two Core Restrictions
Both restrictions apply for the first 12 months after license issuance, or until the driver turns 18 — whichever comes first. After 12 months (or turning 18), these restrictions lift automatically and the license becomes a standard Class C.
Restriction 1: Nighttime Driving
As a provisional driver, you cannot drive between 11 p.m. and 5 a.m. during the first 12 months you have your license — unless one of the written exceptions applies (see below). "Driving" includes being behind the wheel on any public road, regardless of distance.
Restriction 2: Passengers Under 20
You may not drive with passengers who are under 20 years old unless your parent or guardian, or another California-licensed driver at least 25 years old, is in the vehicle with you. This includes siblings, friends, cousins, and anyone else under 20.
There is no "one friend exception" like some states have. If the passenger is under 20 and no qualifying adult is present, it's a violation.
The Exceptions
The handbook lists four written exceptions. Each requires a signed note carried with the driver at all times. No note, no exception.
1. Medical necessity
If you have a medical need and cannot reasonably find another way to travel, you must carry a note signed by your physician. The note must state your medical condition and the date you are expected to recover.
2. School or school activity
If you must drive for school or a school activity, carry a note signed by your school principal, dean, or a designee of either.
3. Work
If you must drive for work reasons, carry a note signed by your employer confirming your employment.
4. Immediate family member
If you must drive an immediate family member, carry a note signed by your parent or legal guardian. The note must state the reason you need to drive, which family member, and the date when the need will end.
Other Rules That Apply to Provisional Drivers
No commercial driving
Provisional drivers cannot drive for pay or operate vehicles that require a commercial Class A, B, or C license. Gig-economy work requiring driving (rideshare, delivery services with vehicle requirements) is off-limits until the provisional period ends.
Hands-free law is stricter for minors
Adult drivers may use a cell phone in hands-free mode when necessary. Minors cannot use a cell phone even in hands-free mode while driving, with one exception: a minor may use a cell phone to make a call for emergency assistance.
Zero-tolerance alcohol
Any BAC of 0.01% or higher under age 21 is illegal. A single drink can put a teen over this limit. Conviction can revoke the driving privilege for one year.
What Happens If You Violate a Restriction
The DMV can take action against a provisional license based on at-fault collisions or traffic violations during the first 12 months. Per the handbook:
| Violations or at-fault collisions | DMV action |
|---|---|
| 1 at-fault collision OR 1 traffic violation conviction | Warning letter from DMV |
| 2 at-fault collisions, 2 traffic convictions, or 1 of each | Restricted driving for 30 days — cannot drive unless a licensed adult (25+) rides with you |
| 3 at-fault collisions, 3 traffic convictions, or combination | Driving privilege suspended for 6 months, then probation for 1 year |
| Alcohol/drug conviction at age 15–20 | 1-year suspension or delayed eligibility to apply for a license |
Parent Cancellation Rights
A parent or guardian can cancel a minor's license at any time by completing a Request for Cancellation or Surrender of a Driver License or ID Card form with the DMV. This is rarely used, but it's a tool parents have if a teen's driving becomes unsafe before the 18th birthday.
What Ends at 12 Months (or Age 18)
- The 11 p.m. – 5 a.m. nighttime restriction
- The "no passengers under 20" restriction
- The "provisional" label on the license becomes a standard Class C on the next renewal
What does not change automatically: the under-21 zero-tolerance BAC limit (0.01%) applies until age 21, regardless of license status. The minor hands-free cell phone rule applies until age 18.
For Parents: Supervising a Provisional Driver
The 12-month provisional period is the highest-risk driving window in a person's life. The handbook emphasizes that most first-year collisions happen in exactly the situations the restrictions try to prevent — late at night, with peer passengers, on unfamiliar routes. The restrictions are designed to delay exposure to those conditions until the driver has a full year of low-risk experience.
Practical tips:
- Keep the permit-era 50-hour log for at least 12 months after licensure — if the teen has an at-fault collision, Driver Safety may request it.
- If your teen genuinely needs to drive between 11 p.m. and 5 a.m. for work, get the employer's signed note ahead of time and keep a copy in the glove compartment.
- If your teen drives siblings, write a note that meets the four-element requirement (reason, family member, end date, signature). Update it whenever circumstances change.
