Does California Law Prohibit Using a GPS While Driving?

GPS technology has become a necessity for many people, but it can be one of the most distracting activities for drivers. A 2017 AAA study found that programming GPS navigation took an average of 40 seconds—the most distracting task involving in-vehicle technology, more so than texting.

Distracted driving (which includes programming navigation systems) was responsible for 3,275 deaths in 2023, according to the National Highway Traffic Safety Administration.

In light of the dangers of distracted driving, most states, including California, have laws that prohibit cellphone use and text messaging and using other electronic devices while driving.

Using a GPS Device While Driving

California doesn't specifically ban GPS devices in its distracted driving law. However, the law states that a person shall not drive a motor vehicle while "holding and operating" a wireless phone or electronic wireless communications device unless it's a voice-operated and hands-free device. A person may also use a device that's a manufacturer-installed system in the vehicle. (Cal. Veh. Code § 23123.5 (2025).)

Although the law doesn't specifically mention a GPS device, it should fall under the broad definition of "electronic wireless communications device." The definition states that it includes, but isn't limited to, "a broadband personal communication device, a handheld device or laptop computer with mobile data access, or a pager." (Cal. Veh. Code § 23123.5 (2025).)

There is an exception to the hands-free rule. A driver may use a hand to operate a device if:

• activating or deactivating the device with a single swipe or tap of the driver's finger, and
• the device is mounted on the windshield (as described below) or is part of (or attached to) the vehicle's dashboard or center console.

(Cal. Veh. Code § 23123.5 (2025).)

What Are the Mounting Requirements for a GPS Device?

California allows a GPS device to be mounted in:

• a seven-inch square in the lower corner of the windshield farthest from the driver, or
• a five-inch square in the lower corner of the windshield nearest to the driver.

The GPS device must not be in the way of airbags and may only be used for door-to-door navigation. (Cal. Veh. Code § 26708 (2025).)

As noted above, a GPS device may also be part of "manufacturer-installed systems that are embedded in the vehicle."

What Are the Penalties for Illegally Using GPS?

Using a GPS that doesn't comply with the above law is an infraction. It is punishable by a $20 fine for a first offense and a $50 fine for every subsequent offense. (Cal. Veh. Code § 23123.5 (2025).)

Best Practices for Driving With a GPS Device

Even if your GPS is legal to use, it's generally a good idea to let a passenger manage it while you're driving. Because even a voice-operated GPS can be distracting, solo drivers should consider pulling over—when it's safe and legal to do so—to enter or change their destination.
