You must keep your mind free while driving, not just your hands.
A hands-free device is one that is designed to work without being held, preferably one that responds to your voice to operate. These devices can dial a phone number and answer phone calls and/or get directions.
Where Dangers Really Occur
While keeping your hands on the steering wheel and your eyes on the road is critical, there is more involved in safe driving.
You need to be paying attention to the road. You must concentrate on your driving, vehicles around you and sudden changes that can cause accidents. Just having a conversation with a passenger in your vehicle can distract you.
Now consider the additional distraction if you are arguing with someone. Having a conversation with someone who is not in your vehicle is not any different. Your mind can only focus on one thing at a time. Hands-free phones have been recommended, especially by companies that sell phones, because it seems that talking on them is okay because drivers need not take their eyes off the road.
Thinking about a conversation requires mental capacity needed for safe driving.
Before you use a hands-free device, ask yourself these questions:
Is it really hands-free? Do I have to look at the screen constantly? Can I concentrate or is the device distracting?
If you constantly have to fiddle with controls on your device, it is not hands-free. If you have to look away from the road to read a text screen, you could miss a car pulling out in front of you. Even mapping devices located on the dash near your steering wheel require you to take your eyes off the road.
Drive Hands-Free and Mind-Free
Your best option is not to use any type of cell phone while driving. If a call is critical, pull off the road to have the conversation. Your safety, your family’s and that of other drivers is more important than any call.
Plan a road map before you travel. If you become lost, pull over to figure out where you are.
