California Cell Phone Law While Driving: Hands-Free, Texting, Under 18

The California cell phone law while driving is short. No driver may hold and operate a phone while driving (Vehicle Code 23123.5). An adult may use a phone only hands-free, or mounted on the windshield, dashboard or center console and touched with a single swipe or tap. Drivers under 18 may not use a phone at all while driving, even hands-free, except to call for emergency help (Vehicle Code 23124).

The DMV handbook calls cell phones "the main source of distracted driving". Below is what each law says, the questions families ask about texting, GPS and emergencies, and the habit we coach so the phone never becomes a question on the road.

Can you use your phone while driving in California?

Only in limited ways. Vehicle Code 23123.5(a) says a person shall not drive while holding and operating a handheld wireless phone or electronic wireless communications device, unless the device is designed and set up for voice-operated, hands-free use and is used that way. The law defines "electronic wireless communications device" broadly. It includes broadband personal communication devices, handheld devices or laptops with mobile data access, and pagers.

A phone may be touched while driving only when both conditions in 23123.5(c) are met:

Systems the manufacturer built into the car are outside this section (23123.5(b)). A phone that is not mounted, whether in your hand, on your lap or in a cup holder, does not qualify for the single swipe or tap allowance.

The California cell phone law while driving, at a glance

What is the California cell phone law for drivers under 18?

Two details matter for parents. First, an officer may not stop a car only to check whether a teen is breaking 23124, but may stop a car for a handheld violation under 23123 or 23123.5. Second, the DMV's provisional licensing sheet notes the rule does not apply on private property, and the emergency call exception in 23124(f) covers calls to police, a health care provider, the fire department or other emergency services.

In practice: no calls, no voice texting and no streaming by tapping the screen for a driver under 18. The other first-year rules are in our provisional license guide.

Is texting while driving illegal in California?

Yes, for everyone, when it means handling the phone. Typing or scrolling a message takes more than a single swipe or tap, so it is not allowed even on a mounted phone, and doing it with the phone in your hand is exactly what 23123.5 forbids. The handbook's advice is plainer than the statute: "Do not send or read text messages or emails while driving." An adult using a phone built and set up for voice-operated, hands-free use is not breaking 23123.5, but the handbook still says adults "should only use a cell phone in hands-free mode when necessary." For drivers under 18, voice texting is not allowed at all.

Can I use my phone for GPS while driving?

Adults can, within the same limits. Mount the phone where it does not block your view, enter the address before you move, and touch it only with a single swipe or tap while driving. Changing the route, typing a new address or zooming in by hand is more than one motion, so pull over first.

For drivers under 18, Vehicle Code 23124 lists no exception for maps or GPS. Plan the route before leaving, write down the turns for an unfamiliar trip, or let a parent or other passenger handle directions. If you are lost, park somewhere safe, and only then pick up the phone.

What if there is an emergency?

Vehicle Code 23123(c) and 23124(f) both exempt calls for emergency purposes, naming calls to a law enforcement agency, health care provider, fire department or other emergency services. The DMV handbook says minors may use a cell phone to make a call for emergency assistance. The adult handheld ban in 23123.5 lists no such exception for ordinary drivers, so an adult should use voice dialing or the mounted phone, or pull over first when the situation allows. A call to say you are running late is not an emergency.

What are the fines and points?

The three phone laws set the same base fine: $20 for a first offense and $50 for each later offense. That base fine is not the whole bill. Penal Code 1464, for example, adds a state penalty of $10 for every $10 of fine on Vehicle Code violations, and other assessments can apply, so the amount on a real ticket is higher. We do not quote a total because it depends on the court.

Since July 1, 2021, a violation point is added for a conviction under 23123(a), 23123.5(a) or 23124(b) when it happens within 36 months of a prior conviction for the same offense (Vehicle Code 12810.3). For a provisional driver, points matter more: under Vehicle Code 12814.6, two points in 12 months bring a 30-day restriction, and three bring a six-month suspension and a year of probation.

How the law got here

The section pages on the state legislature's site show the history. Vehicle Code 23123 requires hands-free listening and talking, in a version that became operative on July 1, 2011. Vehicle Code 23124, the under-18 rule, has been in its current form since January 1, 2014. Vehicle Code 23123.5, the handheld ban with the mount and single swipe or tap rule, was last amended by AB 1222 in 2017, effective January 1, 2018. AB 47 (2019) set the repeat-offense point for violations on or after July 1, 2021. Check these sections again before relying on an old article, because the rules have changed several times.

What we coach: the phone in the glovebox

The law sets the minimum. Our habit is simpler: the phone is silenced and put away, in the glovebox or a bag on the back seat, before the car moves. If it is out of reach, there is nothing to decide when it buzzes. We pair that with a three-step start: route set, music set, phone away.

It is also a rule in our cars. During a lesson, a student may not use a handheld device. Our teaching method explains why it matters. We train eyes 12 to 15 seconds down the road, and commentary driving keeps the student talking about what they see. A glance at a screen breaks both, and the instructor can hear it in the commentary when the student's attention drifts.

Picture a common moment in an early lesson: a phone buzzes in a pocket and the student's eyes drop. The instructor says one calm sentence, "Eyes up, we'll check it when we park," and at the next stop the phone goes into the glovebox. Parents can use the same line during supervised practice. See the teen 6-hour training for how lessons run.
