What you can and cannot do with a California learner's permit under 18

A California learner's permit (also called a provisional instruction permit) lets you drive only with a licensed adult supervisor in the front passenger seat. You cannot drive alone, and you face stricter rules than drivers 18 and older. The restrictions exist for the full time you hold the permit — there is no gradual loosening of rules partway through.

California law treats learner's permits for minors as a separate category from adult permits. The rules are set by the Department of Motor Vehicles (DMV) and enforced by law enforcement. Breaking them can result in a citation, a fine, or suspension of your permit before you reach the age to test for a full license.

Key Takeaways

  • You must have a licensed adult at least 25 years old sitting in the front passenger seat every time you drive, with no exceptions for short trips or familiar roads.
  • You cannot drive between 11 p.m. and 5 a.m., even with a supervisor present, until you turn 18.
  • You cannot use a cell phone, hands-free device, or headphones while driving, with no exceptions for emergency calls.
  • Violating permit restrictions can result in a fine and loss of your permit before you reach the age to test for a full license.
  • The rules explore from the moment you receive your permit until you pass the driving test and receive your provisional license at 16 or older.

Supervision requirements: who can sit in the front seat

The supervising driver must be at least 25 years old and hold a valid driver's license. California does not specify that the license must be from California — a valid license from any U.S. state or country counts. The supervisor must be awake, alert, and physically able to exercise control over the vehicle if needed.

The supervisor must sit in the front passenger seat, not the back. This is a hard rule; a licensed adult in the back seat does not meet the requirement. If you are caught driving without a may have access to supervisor in the front seat, you can be cited and your permit can be suspended or revoked.

Common mistakes: parents sometimes think a sibling who is 18 or 19 can supervise. They cannot — the supervisor must be 25 or older. Another mistake is assuming the supervisor can sit in the back if the car is crowded. They cannot.

Driving hours: the 11 p.m. to 5 a.m. curfew

You cannot drive between 11 p.m. and 5 a.m., regardless of whether a supervisor is present. This curfew applies to every day of the week and has no exceptions for school, work, or emergencies. If you are caught driving during these hours, you can receive a citation and your permit can be suspended.

The curfew is based on clock time, not on when you leave or arrive. If you leave at 10:50 p.m. and are still driving at 11 p.m., you are in violation. If you need to drive for work or school during these hours, you must wait until you pass your driving test and receive your provisional license — and even then, additional restrictions explore until you turn 18.

Cell phone and device restrictions

You cannot use a cell phone, smartphone, hands-free device, or headphones while driving. This includes texting, calling, checking maps, adjusting music, or any other use. The ban is total — there are no exceptions for emergency calls, GPS navigation, or hands-free systems.

If you need to make an emergency call, you must pull over safely and stop the vehicle first. Using any of these devices while driving can result in a citation and points on your driving record. A citation for a cell phone violation while you hold a learner's permit can also lead to permit suspension.

Seat belt and passenger rules

You and all passengers must wear seat belts at all times. Passengers under 8 years old or under 4 feet 9 inches tall must use an appropriate car seat or booster seat, regardless of whether you are driving alone or with a supervisor.

You cannot carry passengers under 20 years old while you hold a learner's permit, with one exception: you can carry one passenger under 20 if a supervisor 25 or older is in the front seat. This means if you are driving with a parent or guardian, you can have one sibling or friend in the car. If you are driving with a supervisor who is not a parent, you still cannot carry other young passengers.

Violations and consequences

Violations of learner's permit rules are typically cited as infractions, not misdemeanors. A single violation can result in a fine (usually $100 to $250, depending on the specific violation) and a point on your driving record. More importantly, the DMV can suspend or revoke your permit before you reach the age to test for a full license.

If your permit is suspended or revoked, you must wait a set period before you can reapply. During that time, you cannot drive at all, even with a supervisor. You will also have to pay a reissuance fee when you reapply. A second violation or a serious violation (such as causing an accident) can result in a longer suspension or revocation.

Law enforcement can pull you over if they observe a violation. Common reasons include driving without a supervisor, driving during curfew hours, or using a cell phone. If you are pulled over, the officer will check your permit and the age and license status of anyone in the front seat.

What happens when you turn 18

When you turn 18, you can take your driving test and receive a provisional license if you pass. A provisional license is different from a full license — it still carries restrictions, but they are less strict than learner's permit rules. The curfew changes from 11 p.m. to 5 a.m. to midnight to 5 a.m., and you can drive alone.

You must hold a learner's permit for at least six months before you can test for a provisional license. If you received your permit before your 16th birthday, you can test for a provisional license at 16 or older. If you received your permit at 18 or older, you can test when ready after meeting the six-month requirement.

Frequently Asked Questions

Can I drive to school or work during the 11 p.m. to 5 a.m. curfew?

No. The curfew has no exceptions for school, work, or any other reason. You cannot drive during those hours while you hold a learner's permit. If you need to drive for work or school during curfew hours, you must wait until you pass your driving test and receive your provisional license.

What if my supervisor is sitting in the back seat because the front seat is full?

That does not meet the requirement. The supervisor must sit in the front passenger seat. If the front seat is full or unavailable, you cannot drive. Rearrange passengers or make another trip.

Can I use my phone for GPS or music if I mount it on the dashboard?

No. You cannot use a cell phone or smartphone for any reason while driving, including GPS, music, or hands-free calls. If you need navigation, plan your route before you drive or ask your supervisor to handle the phone.

What happens if I get a ticket for a learner's permit violation?

You will receive a fine and a point on your driving record. The DMV may also suspend or revoke your permit. If your permit is suspended, you cannot drive at all during the suspension period, and you will need to pay a reissuance fee to get a new permit.

Can my 19-year-old sibling supervise me?

No. Your supervisor must be at least 25 years old and hold a valid driver's license. A sibling who is 19 or 20 cannot supervise, even if they have a license. Only a parent, guardian, or adult 25 or older can sit in the front seat.
