California cellphone driving law
San Jose, CA – A California appeals court has issued a significant ruling that clarifies what it means to “operate” a mobile phone while driving. The court now considers even holding a phone to view maps as a violation of state law. This decision strengthens California’s efforts to combat distracted driving and sets a clear precedent for road safety.
Background: California’s Cellphone Driving Law
The 2016 Law Explained
In 2016, California passed a law that prohibited any form of hand-held mobile phone use while driving. The intent was to address the growing issue of distracted driving linked to smartphones. The law specifically states that a driver may not “operate” a wireless phone unless it is mounted and used hands-free, with only a single tap or swipe allowed.
Key Difference From Previous Law
Earlier laws, including a 2014 ruling, focused narrowly on talking or listening with a phone. But the 2016 update, introduced by Assembly Member Bill Quirk (D-Hayward), broadened the scope to include all hand-held use—acknowledging the expanded capabilities of modern phones beyond calls.

Court Ruling: Looking at Maps is Illegal Too
What the Appeals Court Decided?
The 6th District Court of Appeal ruled that holding a mobile phone—even just to view a map—is illegal. The decision reinstated a conviction and $158 fine for a driver, Nathaniel Maranwe, who used his phone for navigation while holding it.
The court stated:
“The Legislature intended to prohibit all handheld functions of wireless telephones while driving.”
This ruling essentially confirms that holding a phone for any purpose—including maps—violates the law.

Reaction: Legal and Public Safety Concerns
Driver’s Perspective
Maranwe, a lawyer representing himself, raised concerns that the law’s language was unclear. He warned that laws should not be enforced in ways the public cannot reasonably understand. He has yet to decide whether to appeal to the California Supreme Court.
Official Response
Santa Clara County District Attorney Jeff Rosen responded to the decision with a powerful message:
“Keep your hands on the wheel and your eyes on the road.”
This aligns perfectly with the law’s intent: reducing distracted driving and saving lives.
What California Drivers Need to Know?
Key Takeaways:
- Do NOT hold your phone even for navigation, while driving.
- Use a mounted phone with hands-free functionality.
Only a single tap or swipe is allowed to activate GPS or calls.
Avoid any manual interaction that takes your hands or eyes off the road.
Hands-Free Tips:
Invest in a reliable phone mount for your dashboard or windshield.
Use voice commands via Siri, Google Assistant, or other apps.
Set up your GPS route before you start driving.
Enable “Do Not Disturb While Driving” mode to limit distractions from notifications.
If you need to change your route or settings, pull over to a safe location first.
These simple steps can help you stay safe and avoid fines or legal trouble while driving in California.
Broader Impact: Safety and Awareness
This ruling is a reminder that technology use behind the wheel must be managed responsibly. As more people rely on smartphones for everyday tasks like navigation, it’s essential to understand the legal boundaries. The decision is likely to influence how law enforcement officers issue citations and how drivers use devices across the state.
Public safety campaigns may now shift focus toward educating drivers on the dangers of even momentary distractions. This could also inspire other states to adopt similar strict interpretations of “operating” a device while driving.

Conclusion: A Clear Message for Road Safety
The California appeals court’s decision sends a strong and simple message: “Keep your hands on the wheel and your eyes on the road.” As technology continues to evolve, California’s laws are adapting to ensure that safety remains the top priority for everyone behind the wheel.
