Driving with headphones in California is illegal. Under California Vehicle Code Section 27400, no driver may operate a motor vehicle while wearing headphones, earbuds, or any headset that covers or sits in both ears at the same time.

The law applies to every driver on every California road. It does not matter whether the music is low or the call is short. If both ears are covered, you are breaking the law.

Many California drivers are surprised to learn this rule exists. Keep reading to learn exactly what CVC 27400 covers, what is and is not allowed, and what happens if a headphone-wearing driver causes an accident that injures you.

What California Vehicle Code 27400 Actually Says

California Vehicle Code 27400 states that no person may operate a motor vehicle while wearing a headset covering, or earplugs in, both ears.

The key phrase is both ears. The law does not prohibit using a single earbud or a one-ear headset. It specifically targets setups that block both ears at the same time. The reason is straightforward. Blocking both ears prevents a driver from hearing emergency sirens, car horns, railroad crossing signals, and other road sounds that are critical for safe driving.

The law applies to:

• Both earbuds in at the same time — this is the most common violation
• Over-ear headphones covering both ears — common with music and gaming headsets
• Noise-canceling headphones — even if the music is off, covering both ears is a violation
• Bluetooth headsets covering both ears — regardless of whether a call is active

What Is Allowed Under CVC 27400

Not every headphone or audio setup is illegal while driving. California law permits several exceptions.

Single Earbud Use

Using one earbud or one in-ear headphone is legal in California. The law only prohibits covering or blocking both ears simultaneously. Many drivers use a single earbud for phone calls or navigation while leaving the other ear open.

Bone Conduction Headphones

Bone conduction headphones do not sit in or over the ear. They rest on the cheekbones and transmit sound through vibration rather than blocking the ear canal. Because they do not cover the ears, they are generally considered legal under CVC 27400. However, consult an attorney if you have questions about your specific device.

Hearing Aids and Medical Devices

California Vehicle Code 27400 explicitly exempts hearing aids and prosthetic devices designed to aid hearing. A driver who wears hearing aids in both ears is not in violation of the law.

Emergency Vehicles

The law also exempts drivers of authorized emergency vehicles. A first responder operating an emergency vehicle may use communication headsets as required by their duties.

What Is the Fine for Driving with Headphones in California?

A CVC 27400 violation is an infraction — not a misdemeanor. It will not result in an arrest or a criminal record.

However, it will cost you money. The base fine for a CVC 27400 violation is approximately $197, but California court fees and penalty assessments typically bring the total closer to $160 to $250 depending on the county.

Importantly, a CVC 27400 infraction does not add a point to your DMV driving record. California’s point system applies to moving violations. Driving with headphones is not classified as a moving violation under current law.

That said, the financial and legal consequences become far more serious if a headphone-related distraction contributes to a car accident.

How Driving with Headphones Affects a Car Accident Claim

This is where driving with headphones in California becomes a serious legal issue beyond a simple traffic fine.

Headphone Use as Evidence of Negligence

In California personal injury law, negligence means failing to exercise the level of care a reasonable person would use in the same situation. Violating a traffic law—including CVC 27400—is evidence of negligence.

If a driver was wearing both earbuds at the time of a crash, that fact can be used against them in a personal injury lawsuit. It does not matter whether the headphones directly caused the accident. The violation shows that the driver was not operating their vehicle with the standard of care required by California law.

Comparative Fault in California

California follows a pure comparative fault system. This means fault in an accident can be divided between multiple parties. If a driver had both earbuds in and failed to hear an approaching vehicle, their level of fault increases.

Even if the headphone-wearing driver was not the primary cause of the crash, their violation of CVC 27400 can reduce the compensation they recover — or increase the compensation owed to the person they injured.

What Insurance Companies Do With This Information

Insurance adjusters look for any reason to reduce a payout. If a police report or witness statement mentions that a driver was wearing headphones at the time of the crash, that detail will be used during the claims process.

This is why it is important to document the scene thoroughly after any accident. If you believe the other driver was wearing headphones and failed to hear your horn or respond to road conditions, tell your attorney. That detail matters.

What to Do If a Distracted Driver Injured You in California

If you were injured by a driver who was wearing headphones, talking on a handheld phone, or otherwise distracted at the time of the crash, you may have a strong personal injury claim.

Here are the steps to take right away.

Call 911 and Get a Police Report

Always request a police report after an accident. Officers document what they observe at the scene. If the other driver had headphones in or a device in their hand, that observation belongs in the official record.

Document Everything You Can

Take photos of the other driver’s vehicle, your injuries, the road conditions, and the accident scene. If you noticed the other driver wearing headphones before or after the crash, write it down immediately while your memory is fresh.

Do Not Give a Recorded Statement to the Other Driver’s Insurer

Insurance companies often contact accident victims quickly to obtain a recorded statement. You are not required to give one. Speak with an attorney before making any statements to the opposing insurer.

Contact a Personal Injury Attorney

An experienced California car accident attorney can investigate whether the other driver was in violation of CVC 27400 at the time of the crash. Your attorney can obtain phone records, witness statements, and police reports to build the strongest possible case on your behalf.

Frequently Asked Questions About Driving with Headphones in California

Can I use wireless earbuds while driving in California?

Only one at a time. Using a single wireless earbud—such as one AirPod—is legal under California law. Using both wireless earbuds at the same time violates CVC 27400, regardless of whether they are wireless or wired.

Does CVC 27400 apply to cyclists and motorcyclists?

Yes. California Vehicle Code 27400 applies to the operators of any motor vehicle. It also applies to bicycle riders. A cyclist wearing both earbuds on a California road is in violation of the same law.

Can a passenger wear headphones in both ears?

Yes. CVC 27400 only applies to the person operating the vehicle. Passengers may wear headphones in both ears without any legal restriction.

What if my headphones were in but no music was playing?

It does not matter. The law prohibits covering both ears regardless of whether audio is playing. If both ear canals are blocked or covered, you are in violation of CVC 27400.

Does this law apply on private property?

No. The California Vehicle Code applies to public roads and highways. Driving on private property—such as a private parking lot or a farm road—is not subject to CVC 27400.
