Who Can Legally Drive While Wearing a Headset in California? The Law Explained

California Vehicle Code Section 27400 prohibits drivers from wearing any headset or earplugs covering, resting on, or inserted in both ears while operating a motor vehicle. The law is intended to preserve the driver’s ability to hear emergency vehicle sirens, horns, and other safety-critical audio cues. However, there are specific exemptions, and violations of this law can affect accident liability determinations under California’s negligence per se doctrine.

Key Takeaways

• California Vehicle Code Section 27400 prohibits wearing any earplugs or headset covering both ears while driving
• Single-ear headsets (Bluetooth, wired) are legal for drivers
• Exemptions include: solid waste (trash truck) and construction equipment operators, hearing-impaired drivers wearing hearing aids, drivers wearing noise-attenuating hearing protectors designed to still allow sirens and horns to be heard, and authorized emergency vehicle operators
• A violation of CVC Section 27400 is an infraction punishable by fines; it can also support a negligence per se claim in accident litigation
• California Evidence Code Section 669 provides that a statutory violation creates a presumption of negligence if it caused the plaintiff’s injuries

Who Is Permitted to Drive With a Headset or Earplugs

Single-ear use: California law only prohibits covering or inserting devices in BOTH ears simultaneously. Wearing a single-ear Bluetooth headset, single-ear earbud, or hearing aid in one ear while driving is legal and common.

Hearing aids: Drivers who are hearing-impaired and wear medically prescribed hearing aids in both ears are exempt from Section 27400.

Noise-attenuating hearing protectors: Earplugs or molds specifically designed to attenuate injurious noise levels are also exempt, but only if they are built to still allow the wearer to hear a siren, horn, or other emergency signal. Ordinary foam earplugs worn for sleep or general noise-blocking do not qualify for this exemption.

Exemption for certain occupational drivers: CVC Section 27400 exempts drivers operating vehicles in certain occupational roles, including solid waste collection vehicles (trash trucks) and construction equipment. These exemptions exist because hearing protection is required for occupational safety in those environments.

Emergency vehicles: Drivers of authorized emergency vehicles may be exempt during emergency operations.

Practical Application: What Is Prohibited

You may NOT drive with: both earbuds in (wired or wireless); noise-canceling headphones covering both ears; over-ear headphones covering both ears. Even if you are only listening at low volume, covering both ears is illegal.

How Headset Violations Affect Accident Claims

If a driver involved in your accident was wearing illegal dual-ear headphones or earbuds, Attorney Damoun Yazdi can argue negligence per se under California Evidence Code Section 669: the driver violated CVC Section 27400, which was designed to protect other road users from drivers with impaired situational awareness, and that violation contributed to the accident.
