The most effective way to prevent becoming distracted by a cell phone while driving is

• A. Turn on your phones Do Not Disturb mode
• B. Set the phone to silent
• C. Use a hands-free system
• D. Keep the screen brightness high

Answer: (D)

Minimizing engagement with the phone is the key to staying focused while driving. The most effective approach is to silence or block notifications so alerts, messages, or incoming calls don’t grab your attention. When you enable a mode that prevents those interruptions, you drastically reduce the moments you might reach for the phone or glance at it, keeping your eyes and mind on the road.

Keeping the screen brightness high, by contrast, makes the phone more noticeable and easier to see. That visibility can draw your eyes toward the screen and pull your attention away from driving, which increases the temptation to check it. So brightness is not a means to prevent distraction; it tends to do the opposite.
