California’s cell phone law bars you from holding or manually operating a phone or any wireless device while you’re driving. If you want to use your phone behind the wheel, it has to be mounted and operated hands-free through voice commands or Bluetooth, with one narrow exception for a single tap or swipe to start or stop a function. A first ticket costs roughly $150 once assessments are added, and a second conviction within three years puts a point on your driving record.
What Counts as Legal Phone Use
Vehicle Code Section 23123.5 makes it illegal to hold and operate a phone or electronic wireless device while driving. Legal use means the device is mounted and you’re running it hands-free. Voice commands, Bluetooth, and speakerphone are fine. Scrolling a playlist, typing an address, reading a message, or dialing a number by hand are not, even briefly.1California Legislative Information. California Code VEH 23123.5 – Driving Offenses
The one built-in exception: if the phone is properly mounted, you’re allowed a single tap or swipe to turn a feature on or off. One tap to launch navigation. One tap to accept or end a call. Anything beyond that single gesture puts you back in violation, and officers don’t have to prove what was on the screen. Watching your finger move across the phone more than once is enough.1California Legislative Information. California Code VEH 23123.5 – Driving Offenses
Where the Phone Has to Be
The single-tap allowance only applies when the phone is secured in an approved spot. You have three: the dashboard, the center console, or the windshield. Windshield mounts follow the same placement rules as portable GPS units under Vehicle Code Section 26708, and they have to stay clear of the airbag deployment zone.2California Legislative Information. California Code VEH 26708 – Equipment of Vehicles
A phone in your lap, propped on the steering wheel, or wedged between your legs is not mounted. Touch it there and it’s a ticket, however brief the contact.
Red Lights and Stopped Traffic Still Count
This is where most drivers get caught out. California courts treat a stop at a red light or a crawl in gridlock as driving, not parking. In People v. Nelson, an appellate court held that a driver stopped at a red light was in a fleeting pause from movement and remained subject to the hands-free rule. The only way to use your phone without restriction is to pull off the road and park. Engine running in a travel lane means the law applies, moving or not.
What a Ticket Actually Costs
The base fines are small on paper: $20 for a first offense, $50 for each one after that. What you actually pay is several times higher because California adds mandatory penalty assessments, state surcharges, and court fees on top. In practice, a first cell phone ticket runs about $150 to $162. A second or subsequent ticket runs about $250 to $285. Judges can’t waive the assessments.1California Legislative Information.

The Point on Your Record
Cell phone tickets used to be point-free. That changed with AB 47, which amended Vehicle Code Section 12810.3. If you’re convicted of a cell phone violation within 36 months of a prior conviction for the same offense, the DMV adds one point to your driving record. The rule covers the adult hands-free law, the general wireless phone statute, and the under-18 ban.3California Legislative Information. California Code VEH 12810.3 – Drivers Licenses
One point won’t suspend your license on its own. But points stack, and the DMV can label you a negligent operator once you accumulate enough of them across a rolling window. Combined with a speeding ticket or an at-fault accident, a cell phone point can move you toward a hearing faster than drivers expect.4California DMV. Driver Negligence
What It Does to Your Insurance
A first cell phone ticket without a point may not move your premiums. A second conviction within 36 months will. Once the DMV posts that point, your insurer sees it at renewal. Industry data suggests California drivers with a distracted driving conviction see premium increases in the range of 40 to 50 percent, which can add well over $1,000 across the three years the point stays on your record. The citation, the assessments, and the insurance bump together push the real cost of a second offense into the thousands.
A Total Ban for Drivers Under 18
Drivers under 18 can’t use a phone or any wireless device while driving, period. Vehicle Code Section 23124 rules out hands-free use too: no Bluetooth headset, no speakerphone, no voice-to-text, no mounted device.5California Legislative Information. California Code VEH 23124 – Driving Offenses
Enforcement of the minor’s ban is secondary. An officer can’t pull a teenager over just to check for phone use; they need another reason for the stop, like speeding or a broken taillight. Once the car is stopped, though, a phone in use gets cited. The only exception is a genuine emergency call, such as 911, a hospital, or the fire department.5California Legislative Information.

Commercial Drivers Face Federal Rules
If you hold a CDL and you’re driving a commercial vehicle, federal law is stricter than California’s. Under 49 CFR 392.82, holding a phone is prohibited outright, including while stopped in traffic or at a signal. The only exception is calling emergency services.6eCFR. 49 CFR 392.82 – Using a Hand-Held Mobile Telephone
Penalties dwarf the consumer fines. Drivers face fines up to $2,750 per violation, employers who allow or require handheld use up to $11,000. Multiple violations count as serious traffic offenses and can trigger CDL disqualification.7Federal Motor Carrier Safety Administration. Mobile Phone Restrictions Fact Sheet
Emergency Calls Are Allowed, But Narrowly
You can pick up your phone to call 911, a fire department, a hospital, or law enforcement without violating the statute. The exception covers situations that genuinely require immediate help. Calling a spouse to say you’re stuck in traffic doesn’t count. Emergency vehicle operators are also exempt while on duty.8California Legislative Information. California Code VEH 23123 – Driving Offenses
If you’re cited and want to claim the emergency exception, the burden is on you. Courts treat it as an affirmative defense, so you have to show the call was genuinely urgent. A call log with a 911 entry at the right time is the cleanest proof.
Civil Liability If the Phone Causes a Crash
The ticket is not the worst part of a cell phone violation that ends in a collision. California’s negligence per se doctrine, in Evidence Code Section 669, creates a presumption of negligence when you break a statute designed to prevent the kind of harm that happened. A distracted driving statute and a distracted driving crash line up cleanly.9Justia. CACI No. 418 – Presumption of Negligence Per Se
In practice, a citation at the scene of a crash can carry most of the negligence element of a civil injury claim before a case reaches trial. The injured party still has to prove that your distraction caused their specific injuries, but the hardest piece is already established. Cell phone records are routinely subpoenaed in these cases. Carriers keep call logs, text metadata, and data usage records that can place your phone activity within seconds of the collision, and that evidence is hard to argue against.
