Cell Phone Ticket in California: CVC 23123 and 23123.5 Explained

California has three separate Vehicle Code sections governing wireless device use while driving. Together they form one of the most frequently enforced categories of traffic law in the state. Here is how each section works and what drivers should understand about the citation process.

What the Law Says

Vehicle Code 23123 bars driving a motor vehicle while using a wireless telephone unless the phone is designed and configured to allow hands-free listening and talking and is used that way while driving (Vehicle Code 23123(a)).

Vehicle Code 23123.5 bars driving while holding and operating a handheld phone or other wireless communications device unless it is designed and configured for voice-operated, hands-free operation and is used that way (Vehicle Code 23123.5(a)). A phone mounted on the windshield where the law allows a portable GPS (a 7-inch square in the lower corner farthest from the driver, or a 5-inch square in the lower corner nearest the driver and outside an airbag deployment zone; Vehicle Code 26708(b)(12)), or mounted on or affixed to the dashboard or center console in a way that does not hinder your view of the road, may be operated with a single swipe or tap of a finger (Vehicle Code 23123.5(c)), and systems the manufacturer installed in the vehicle are exempt (Vehicle Code 23123.5(b)).

CVC 23124 governs drivers under 18. The standard for minor drivers is stricter: no wireless device use while driving, including hands-free configurations. The only statutory exception is an emergency call to law enforcement, fire, or medical services.

Fines and DMV Points in 2026

A first offense under CVC 23123 or 23123.5 carries a $20 base fine ($158 total under the Judicial Council’s 2026 bail schedule) and no DMV point. A second or later offense carries a $50 base fine (the schedule prints first-offense totals only, so check your notice for the total). Under Vehicle Code 12810.3, a DMV point is added only when the violation happens within 36 months of a prior conviction for the same offense. The same fine structure applies to minor drivers cited under CVC 23124.

That point rule covers violations on or after July 1, 2021 (Vehicle Code 12810.3, as amended by AB 47). The first-offense total comes from the Judicial Council’s 2026 bail schedule; counties may add local amounts, and your notice shows the exact amount.

Legal Exemptions

Each section lists its own exceptions, so check which section is on your ticket:

• Hands-free use: Vehicle Code 23123 allows a phone that is designed and configured for hands-free listening and talking and used that way, and Vehicle Code 23123.5 allows a device that is designed and configured for voice-operated, hands-free operation and used that way.
• Mounted phone, single swipe or tap: under Vehicle Code 23123.5(c), you may use your hand to turn a feature or function on or off with a single swipe or tap of a finger, but only if the phone is mounted on the windshield where the law allows a portable GPS (a 7-inch square in the lower corner farthest from the driver, or a 5-inch square in the lower corner nearest the driver and outside an airbag deployment zone; Vehicle Code 26708(b)(12)), or mounted on or affixed to the dashboard or center console in a way that does not hinder your view of the road.
• Manufacturer-installed systems: Vehicle Code 23123.5 does not apply to systems the manufacturer installed and embedded in the vehicle (Vehicle Code 23123.5(b)).
• Emergency calls: Vehicle Code 23123 does not apply to using a phone for emergency purposes, such as an emergency call to a law enforcement agency, health care provider, fire department or other emergency services agency (Vehicle Code 23123(c)).
• Emergency services professionals: neither section applies to an emergency services professional using the device while operating an authorized emergency vehicle in the course and scope of their duties (Vehicle Code 23123(d) and 23123.5(e)).
• Private property: Vehicle Code 23123 does not apply while driving a motor vehicle on private property (Vehicle Code 23123(f)).
• School bus and transit drivers: Vehicle Code 23123 does not apply to a person driving a school bus or transit vehicle that is subject to Vehicle Code 23125, which has its own rules (Vehicle Code 23123(e)).

How the Contest Process Works Through TBWD

Citations under CVC 23123 and 23123.5 are infractions and are eligible for Trial by Written Declaration under CVC 40902. Through the TBWD process, the driver submits a written account of events to the court without appearing in person. The citing officer is asked to send a written statement too, describing the basis for the citation — the specific observations that led to the stop and the citation.

The judge reviews the declarations and the other evidence the court has and decides whether the violation was proved. If the officer does not send a statement by the date the court sets, the judge still decides on the evidence the court has, which can include the citation itself (Vehicle Code 40902(c)). The case may be dismissed, but that is the judge's decision and no result is guaranteed.

Common factual issues that arise in cell phone TBWD cases include: whether the driver was holding the device or whether it was in a mount or resting on a surface; whether a hands-free function was active; whether the officer had an unobstructed line of sight to observe the alleged conduct; and whether the call, if any, was made under emergency circumstances.

TBWD is not risk-free. If the court finds the driver guilty, the conviction and DMV points are the same as paying, and the bail deposit is applied to the fine, but the judge can set a fine higher or lower than the bail. Contesting does not make a driver ineligible for traffic school, but after a guilty finding it is up to the judge. If the citation is not dismissed through TBWD, most courts allow a Trial de Novo — an in-person hearing — to be requested; courts that offer online trial by declaration through MyCitations do not.

Special Rules for Minor Drivers — CVC 23124

CVC 23124 applies exclusively to drivers under 18. Unlike the adult standard, which permits hands-free use, CVC 23124 prohibits any wireless device use while driving — including phone calls made through a mounted, voice-controlled device. The emergency exception applies: a minor driver may use a device to contact emergency services when reasonably necessary.

For drivers under 18, the same point rule applies to CVC 23124(b): under Vehicle Code 12810.3, a point is added only for a violation within 36 months of a prior conviction for the same offense. Under California's Graduated Driver License program, multiple moving violations within 12 months can trigger additional restrictions on the provisional license. Drivers under 18 and their parents may benefit from consulting a licensed attorney about how a specific conviction could interact with the Graduated Driver License rules.
