Updated for 2026

This practice test reflects California's current distracted driving laws, including AB-1785 (hands-free requirements) and the 2021 point-system update. Content is based on the official 2026 California DMV Driver's Handbook and the California Vehicle Code.

Distracted driving is one of the most dangerous and preventable causes of crashes in California. The DMV permit test reflects this priority—cell phone and distraction questions appear regularly and cite specific California Vehicle Code sections.

This free practice test covers all of California's major distracted driving statutes. You'll learn the difference between VC 23123 (hands-free law for all adults), VC 23123.5 (texting ban), and VC 23124 (complete prohibition for drivers under 18). You'll also learn the fine structure, the 2021 point-system update, and California's headphone law (VC 27400).

Expect questions about: what adult drivers may and may not do with a mounted phone, why teen drivers face stricter rules than adults, the base fine for a first versus second offense, when a distracted driving violation adds a DMV point, and which distractions are classified as visual, manual, or cognitive.

Why is this on the California Permit Test?

California has enacted some of the nation's strictest distracted driving laws because new drivers are statistically most at risk. You must master:

VC 23123 hands-free law
VC 23123.5 texting ban
VC 23124 teen driver rules
VC 27400 headphone law

California Phone & Texting Laws

California has two core statutes restricting cell phone use while driving. The key rule for adult drivers: Never hold the phone. If you want to use it, it must be mounted and operated with a single touch or swipe.

DMV Test Tip: Red Lights

A very common test question asks: "You are stopped at a red light and your phone rings. May you pick it up to answer?"

Answer: No. California's hands-free law applies any time you are behind the wheel with the engine running—including at red lights. You must let it go to voicemail.

Key Statutes at a Glance

VC 23123 — Hands-Free Law: No holding a phone while driving. Adults may use a mounted phone with a single touch/swipe only.
VC 23123.5 — Texting Ban: No reading, writing, or sending any text-based communication while driving—applies even at red lights.
AB-1785 (2017): Phone must be mounted in the lower windshield corner or on the dashboard and operated with a single swipe or voice commands.

Teen Drivers: Stricter Rules (VC 23124)

Drivers under 18 face a complete prohibition on wireless device use—far stricter than the adult hands-free rule. While adults may use a mounted phone with a single touch, teens may not use any wireless device in any way.

What Is Banned for Drivers Under 18

• Handheld calls and texting — same as adults, but also:
• Hands-free Bluetooth — banned even with a single-ear device
• Voice commands — Siri, Google Assistant all prohibited
• Navigation apps — even on a properly mounted phone

The Only Exception

A driver under 18 may use a wireless device only to call 911 in a genuine emergency where there is no safe alternative. This is the sole exception under VC 23124.

Fines & Consequences

California's base fines appear low, but penalty assessments added by the court multiply the actual cost significantly. Starting in 2021, repeat offenders also receive DMV points.

DMV Test Tip: Know the Base Fines

The permit test asks about the base fine, not the total with assessments. Know: 1st offense = $20, 2nd+ offense = $50. A third violation within 36 months also adds one DMV point.

Beyond the Fine: Reckless Driving

• Collision while on phone: Can escalate to reckless driving (VC 23103), a misdemeanor
• Reckless driving penalties: Fines up to $1,000, up to 90 days in jail, DMV points
• Civil liability: You are personally liable for all property damage and injuries caused

Fine Schedule: VC 23123 & VC 23123.5

OffenseBase Fine~Total Cost

1st offense$20~$150–$162

2nd+ offense$50~$250–$285

3rd+ within 36 mo.$50 + point~$285 + insurance

Note: Penalty assessments are added by the court and are not reflected in the base fine. Total costs shown are estimates and may vary by county.

Other Distractions & Headphone Law

Three Types of Distraction

The California DMV handbook identifies three categories. Texting is uniquely dangerous because it causes all three at once.

Visual: Eyes leave the road (reading a text, looking at a passenger)
Manual: Hands leave the wheel (texting, eating, grooming)
Cognitive: Mind leaves driving (phone conversation, daydreaming)

The 2-Second Rule: At 55 mph, a 2-second glance at your phone means traveling ~160 feet—half a football field—completely blind.

Headphone & Earbud Law (VC 27400)

Wearing headphones in both ears while driving is illegal in California.

Legal:Single-ear Bluetooth earpiece or hearing aid

Illegal:Earbuds in both ears—even at low volume or for navigation audio

Why it matters: You must be able to hear emergency sirens and traffic sounds. The law exists for safety, not volume control.

Common Questions

Frequently Asked Questions

Is it legal to use a cell phone at a red light in California?

No. California's hands-free law (VC 23123) prohibits holding or using a handheld phone any time you are behind the wheel with the engine running—including at red lights. The law does not make exceptions for stopped traffic. You must be safely parked with the engine off to legally use a handheld phone.

What is the fine for texting while driving in California?

The base fine under VC 23123.5 is $20 for a first offense and $50 for subsequent offenses. However, California courts add penalty assessments that multiply the base fine significantly. A first offense typically costs around $150–$162 total, and a second or subsequent offense can exceed $280. A third violation within 36 months also adds one point to your DMV record.

Can a 17-year-old use a hands-free Bluetooth device while driving in California?

No. California Vehicle Code 23124 prohibits drivers under 18 from using any wireless communication device while driving—including hands-free Bluetooth devices, voice commands, and navigation apps on a mounted phone. The only exception is calling 911 in a genuine emergency. This is stricter than the rules for adult drivers.

Can I wear earbuds while driving in California?

You can legally wear a headphone or earbud in ONE ear while driving, but not both. California Vehicle Code 27400 prohibits wearing a headset or earplugs in both ears while driving. The purpose of this law is to ensure drivers can hear emergency vehicle sirens and other traffic sounds. Hearing aids are exempt.

What is California's hands-free law and how does it work?

California's hands-free law (VC 23123, strengthened by AB-1785 in 2017) requires that adult drivers who want to use a phone while driving must have it mounted on the windshield or dashboard in an approved mount, and may only interact with it using a single touch or swipe—for example, to answer a call. Scrolling, typing, or holding the phone in any way is illegal. Voice commands that require no touching are also allowed.

What are the three types of driver distraction?

The California DMV handbook identifies three types of driver distraction: (1) Visual distraction — taking your eyes off the road; (2) Manual distraction — taking your hands off the steering wheel; (3) Cognitive distraction — taking your mind off driving. Texting while driving is uniquely dangerous because it causes all three types simultaneously.

Can I use a GPS app on my phone while driving in California?

Yes, as an adult driver, you may use a navigation app while driving if your phone is mounted in an approved location and you interact with it using only a single touch or swipe. You should set up your route before you start driving. Teen drivers under 18 may not use navigation apps on their phones while driving, even if the phone is mounted.

What happens if distracted driving causes a crash in California?

If you cause a collision while illegally using a handheld phone, the charge can escalate from a simple infraction to reckless driving (VC 23103), which is a misdemeanor. This carries penalties including fines up to $1,000, up to 90 days in jail, mandatory DMV points, and civil liability for property damage and personal injury. Your insurance rates can also increase significantly.
