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

A California learner's permit (also called a provisional instruction permit or PIP) lets you drive alone on public roads only if a licensed adult sits next to you in the front seat. You cannot drive alone, even to the store or to school. The adult must be at least 25 years old, hold a valid driver's license, and be physically able to exercise control over the vehicle. You also cannot drive between 11 p.m. and 5 a.m., and you cannot use a cell phone or hands-free device while driving — not even at a red light.

These rules exist because crash rates for teen drivers drop significantly when a supervising adult is present. California's restrictions are stricter than many states because the data shows they work. Breaking them can result in a citation, a fine, and suspension of your permit.

Key Takeaways

  • You must have a licensed adult at least 25 years old in the front seat every time you drive with a learner's permit.
  • You cannot drive between 11 p.m. and 5 a.m., even with a supervising adult present.
  • You cannot use any cell phone, including hands-free or voice-activated devices, while the vehicle is moving.
  • You must hold your learner's permit for at least six months and pass a behind-the-wheel test before you can get a provisional license.
  • Violating permit restrictions can result in fines, citations, and permit suspension.

The supervising adult requirement

The adult in the front seat must be a licensed driver with a valid California driver's license, an out-of-state license, or a valid international driving permit. They must be at least 25 years old. They cannot be a provisional licensee (a teen driver) or someone with a suspended or revoked license. The DMV does not require the adult to be a parent or relative — they can be a driving instructor, a family friend, or anyone else who meets the age and license requirements.

The adult must be physically able to exercise control of the vehicle. This means they need to be alert, sober, and capable of reaching the steering wheel and pedals. If the supervising adult is impaired, distracted, or unable to take control if needed, you are violating the permit rules even if they are sitting next to you.

Nighttime driving restrictions

You cannot drive between 11 p.m. and 5 a.m., regardless of whether a supervising adult is in the car. This applies every night, including weekends and holidays. The only exception is if you are driving to or from work, school, or a school-sponsored event, and you have a signed note from a parent, guardian, or employer in the vehicle. Even with a note, you still need the supervising adult present.

The 11 p.m. to 5 a.m. window is when teen crash rates spike. Fatigue, reduced visibility, and reduced traffic all contribute to higher-risk driving conditions for inexperienced drivers. If you are stopped during these hours without a valid reason and documentation, you can receive a citation.

Cell phone and distraction rules

You cannot use a cell phone, smartphone, or any wireless device while driving, even if the vehicle is stopped at a red light or in traffic. This includes texting, calling, using GPS, checking social media, or using voice-activated features like Siri or Google Assistant. The only exception is if you are calling 911 in an emergency.

Hands-free devices and voice commands are also prohibited. Many drivers assume hands-free means legal for permit holders, but California law is clear: no wireless device use at all while the vehicle is in motion. If you need to use GPS, set it before you start driving. If you need to make a call, pull over safely and turn off the engine first.

How long you must hold a learner's permit

You must hold your learner's permit for at least six months before you can take the behind-the-wheel driving test for a provisional license. If you are under 18 when you get your permit, you cannot skip this waiting period — it is a legal requirement, not a guideline. The six months begins on the date the DMV issues your permit, not the date you pass the written test.

During those six months, you are building supervised driving experience. California requires this time because research shows that teen drivers with more supervised hours have lower crash rates. Keep a record of your driving hours and the adults who supervise you, even though the DMV does not require you to log them. This record can help you remember what conditions you have practiced in and what you still need to work on before your test.

What happens if you violate permit restrictions

Driving without a supervising adult, driving during restricted hours without a valid reason, or using a cell phone while driving can result in a citation. The fine for a first violation is typically $100 to $250, depending on the specific violation and the county. A second violation within 12 months can result in a higher fine and suspension of your permit for 30 days.

If your permit is suspended, you cannot drive at all until the suspension period ends and you request reinstatement from the DMV. A suspension also delays your ability to take the behind-the-wheel test and get your provisional license. Additionally, a violation can affect your insurance rates once you are licensed, because insurance companies can see traffic citations on your driving record.

Moving from a learner's permit to a provisional license

After you have held your learner's permit for at least six months and passed the behind-the-wheel test, you can get a provisional license. A provisional license (also called a restricted license) allows you to drive alone, but it still has restrictions until you turn 18. You cannot drive between midnight and 5 a.m. unless you are driving to or from work, school, or a school-sponsored event. You also cannot have more than one passenger under 20 years old in the vehicle unless a supervising adult is present.

The provisional license restrictions are less strict than the learner's permit rules, but they are still in place. Once you turn 18, you can request a full unrestricted license, though you will still have the same traffic laws as any other driver.

Frequently Asked Questions

Can my parent sit in the back seat instead of the front seat?

No. The supervising adult must sit in the front seat next to you. The DMV requires this so the adult can physically reach the steering wheel or pedals if they need to take control of the vehicle. A supervising adult in the back seat does not meet the requirement.

What if I get pulled over and the supervising adult does not have their license with them?

The officer can cite you for driving without a proper supervising adult, even if the adult is licensed and old enough. The supervising adult should always carry their valid driver's license. If you are cited, you may be able to show proof of their license later in traffic court, but it is better to prevent the stop by ensuring the adult has their license before you drive.

Can I drive to school alone if I have a learner's permit?

No. You cannot drive alone under any circumstances with a learner's permit, even to school. You need a supervising adult in the front seat. Once you get a provisional license, you can drive to school alone during the day, but not between midnight and 5 a.m. unless you have a signed note from your school or employer.

Does the supervising adult have to be my parent?

No. The supervising adult can be any licensed driver at least 25 years old who is physically able to control the vehicle. This can be a parent, relative, friend, driving instructor, or anyone else who meets the requirements. They do not need to be related to you.

What counts as a valid reason to drive between 11 p.m. and 5 a.m.?

Valid reasons are driving to or from work, school, or a school-sponsored event. You must have a signed note from a parent, guardian, employer, or school official in the vehicle. The note should state the reason, the date, and the time you need to drive. Without a note, you cannot drive during these hours even with a supervising adult present.
