As of June 3, 2025, a new ruling from the California Court of Appeal has made it crystal clear: holding your phone for any reason while driving is illegal under California law.

In People v. Porter (2025), the court interpreted Vehicle Code § 23123.5 to prohibit not only talking or texting while holding a phone, but also using it for navigation, maps, or even music, regardless of whether you’re stopped at a red light or stuck in traffic.

This decision closes a loophole many drivers relied on, believing that using their phone for directions was allowed as long as they weren’t texting or calling. That is no longer the case. If you’re holding your phone while behind the wheel, even just glancing at GPS, you can be pulled over and cited.

What the Law Requires:

Hands-free only: Your phone must be mounted on the dashboard, windshield, or console.

One tap or swipe only is permitted to activate or deactivate a function (e.g., start navigation).

No hand-held use of any kind, even at stoplights.

Penalties:

First offense: $20, plus assessment fees of about $150

Subsequent offenses: Higher fines and potentially a DMV point on your record.

Why This Matters:

Distracted driving is a leading cause of serious accidents across California. The court’s ruling reinforces the state’s commitment to road safety by eliminating gray areas in cellphone use.
