Pay attention: Ranking 6 driving distractions
Once you've racked up a lot of hours behind the wheel, driving becomes a little pedestrian (no pun intended). Driving distractions abound, though -- be careful.
Driving is a part of everyday life for most Americans. It's so mundane that we rarely think of the potential danger that exists around every bend in the road. Car insurance companies are aware of those risks and price their policies accordingly.
But there are dangers not only on the road -- they're also inside the vehicle, as illustrated by a study from the AAA Foundation for Traffic Safety.
It looked at a number of activities and how likely they are to cause "cognitive distraction" -- in other words, a tendency for a driver's mind to wander. Bruce Hamilton, the AAA foundation's research manager, says testing revealed that some in-vehicle distractions have little impact on a driver's ability to focus on the road, while others present a bigger danger.
In addition, some technological innovations designed to make driving safer may fail to do so, he says.
"Hands-free doesn't mean risk-free, and this is the best evidence to date that shows that," Hamilton says.
Following are some of the distractions AAA examined, and how they rank on the danger scale.
Listening to the radio: Minimal risk
AAA looked at several potentially hazardous distractions that can divert a driver's attention.
Participants in the study were asked to perform each task in three separate settings:
- While not driving.
- While driving in a simulator.
- While driving a car in a real-world situation.
Various measures were used to determine the level of distraction, including brake reaction time and following distance, brainwave activity, and eye and head movements.
In the early stages of testing, the subjects listened to the radio. They adjusted the radio to a comfortable volume before driving and then were not allowed to change the station.
The bottom line? Using your car's radio to hum along with your favorite tunes or to catch up on the latest news does not significantly distract you, the study found.
"We are not raising the alarm about people listening to the radio," Hamilton says.
Listening to a book on tape: Minimal risk
In this section of the study, participants were asked to choose and listen to a section from one of three audio books. (And, for you trivia buffs, the passages were from: "The Giver" by Lois Lowry; "Water for Elephants" by Sara Gruen; and "Harry Potter and the Sorcerer's Stone" by J.K. Rowling.)
Participants then were given a simple five-question quiz about the contents of the passage to ensure they were listening carefully.
The level of distraction when drivers become engrossed in an audio book was slightly higher than when drivers merely listened to the radio.
However, Hamilton says the difference is not significant enough to warrant alarm, and that overall distraction levels remained relatively low.
Talking to a passenger: Moderate risk
The level of distraction became a bit more elevated when test participants chatted with a passenger in the car.
As part of the testing, drivers were asked to have a conversation with a passenger. Participants were asked to spend roughly half the time talking, and the other half listening.
Distraction levels rose about halfway between activities that are not distracting at all, and those that are severely distracting.
Interestingly, it appears that the mere act of conversation is distracting. Drivers were not allowed to turn their heads to look at the passenger while talking, nor to perform actions such as hand gestures that might lead to distraction.
"They were told to keep their eyes on the road and hands on the wheel the whole time," Hamilton says.
Hand-held cellphone use: Moderate risk
For years, auto safety advocates, car insurance companies and other critics have blamed hand-held cellphones for causing significant distractions and leading to accidents and fatalities.
As a result, more than 10 states plus the District of Columbia have banned all drivers from using hand-held phones. D.C. and a majority of states prohibit novice drivers from using a hand-held cellphone behind the wheel.
The AAA test did indeed find that talking on a cellphone causes elevated levels of distraction.
Jonathan Adkins, deputy executive director of the Governors Highway Safety Association, says drivers should not try to multitask when driving and should put away their phones.
He says the association continues to encourage all states to ban both hand-held cellphone use and texting by drivers.
"Any type of cellphone use while driving is dangerous," Adkins says. "The best practice is to turn the phone off and focus on driving."

Hands-free cellphone use: Moderate risk
Hands-free cellphone technology has been touted as a solution to phone-based driver distractions. But the AAA researchers found about the same amount of risk as with hand-held phones.
David Teater, senior director of transportation strategic initiatives at the National Safety Council, says he is not surprised.
"Hands-free does not prevent cognitive distraction," he says.
Other experts have reached the same conclusion. A 2010 study by the Highway Loss Data Institute, a research organization supported by car insurance companies, found no reduction in crashes in states that banned hand-held devices while driving and said the risk is about the same, whether phones are hand-held or hands-free.
Teater says at least 30 major studies have reached similar conclusions.
"The only thing that changes when using hands-free is that one hand goes back on the steering wheel," he says. "We have been driving manual-shift transmissions for years and have not worried about it as a safety hazard."
Speech-to-text systems: Extensive risk
Speech-to-text systems allow drivers to send texts and emails by speaking, then having the technology translate words into a written message. Some systems also allow drivers to complete other tasks, such as updating their Facebook page.
These systems were deemed significantly distracting -- and risky.
"Increased mental workload and cognitive distractions can lead to a type of tunnel vision or inattention blindness where motorists don't see potential hazards right in front of them," explains Peter Kissinger, the president and CEO of the AAA Foundation for Traffic Safety, in a statement.
Hamilton notes that AAA tested a speech-recognition system in which fidelity was perfect. Most commercially available systems do not meet this standard, he says, resulting in a need to review or correct garbled translations. That could mean an even higher level of distraction.
"Our estimate is somewhat conservative," he says.
With the car insurance industry warning that driver distractions can be deadly, researchers are hoping for more dialogue about the safe use of hands-free devices.
"We're not trying to say that these technologies can't be in vehicles," Hamilton says. "We're just trying to put the brakes on their wholesale proliferation."

Most cars in the 50s, 60s, and 70s standardized where the headlight light switch was (far left side of dash), high beam switch was (on the floor), windshield washer/wiper was (next to light switch, etc.). If you were driving your brother's or neighbor's car, you didn't have to look around for these basic controls. Today, they are all over the place (think cruise control). DOT used to require standardization across all manufacturers but deep lobbyist pockets changed all that.
In my current GM vehicles, with numerous digital displays, I must look down to set the digital temperature (left and right sides no less), select the air flow mode (its a displayed picture now), and to alter a myriad of other features (e.g. turn off rear-view mirror dimming). Even more lame are the controls on the door panels for memory seats, power windows, door locks, seat heaters, side view mirror adjustments, and pedal adjustments. First they are small so you need to concentrate where to put your finger which means a full look away from the road. At night, even though some are dimly lit, it's even worse and even more so if you are wearing gloves. More often than not I accidentally turned the heated seat on in July and near fried my **** off. It's not just the cell phones folks, they just add to the problem.
OK, having some radio controls on my steering wheel is a plus but that is only for the basic stuff. If you need to make any other radio adjustments (think balance, graphic equalizer, etc.) to these super powered radios in today's cars, you have to take your eyes off the road. They should be locked out when the vehicle is NOT in Park.
Want to open the sun roof for the first time or close it quickly when it starts to rain at night? Where's the rear defrost button? Rarely is it in the same place across different models and makes. Cruise control in some vehicles is mounted on the turn signal stalk, or its own stalk, or operated through buttons on the steering wheel, alongside those radio buttons I mentioned.
And finally, those NAV systems - they all require some eyes off the road but the built in ones are the worst. At least with the aftermarket NAV systems, you can stick it where it can be viewed, along with the road, the easiest. Factory installed NAV systems, which includes a programmers delight of radio adjustment screens, require a significant look away from the road.
This is a subject that's long overdue for some type of regulation, and standardization. The auto makers have run amuck thinking techie stuff sells.
It's even worse when you combine all this techie stuff with life's other driving distractions like a car of screaming kids, or fighting spouses, or Joe Blow drinking his morning latte while munching on a donut and/or organizing his work papers, or dictating notes. Then you have those who are applying makeup, combing one's hair, etc. You get the idea. Oh yeah, the cell phone is in there someplace too but it is not the sole culprit.
Eating, putting on make-up, disciplining children or pets, reading books/newspapers/maps, watching television, playing video games, etc. etc. etc.
See it all the time, and more.
Hand-held cellphone use listed as moderate.
According to the many a-z-z-wipes I was behind while they were weaving and wandering out of their lane,I suppose it's moderately correct.
Federal law prohibits commercial operators use of hand held electronic devices. Cell phones and presumably all other hand held devices, with one exception, CB radios.
I for one see no difference in talking on a phone I hold in one hand and talking into a hand held microphone. Having driven many hundreds of thousands of miles behind the wheel of a big rig I can say with a voice of experience that CB radio operation is every bit of a distraction that a cell phone is..
Texting is a whole 'nother matter...
