Policy Statement
The primary responsibility of the driver is to operate a motor vehicle safely. The task of driving requires full attention and focus. Cell phone use can distract drivers from this task, risking harm to themselves and others. Therefore, the safest course of action is to refrain from using a cell phone while driving.

Frequently Asked Questions

Q. Does cell phone use while driving cause traffic crashes?

A. Research shows that driving while using a cell phone can pose a serious cognitive distraction and degrade driver performance. The data are insufficient to quantify crashes caused by cell phone use specifically, but NHTSA estimates that driver distraction from all sources contributes to 25 percent of all police-reported traffic crashes.

Q. Is it safe to use hands-free (headset, speakerphone, or other device) cell phones while driving?

A. The available research indicates that whether it is a hands-free or hand-held cell phone, the cognitive distraction is significant enough to degrade a driver’s performance. This can cause a driver to miss key visual and audio cues needed to avoid a crash.

Q. In an emergency should I use my cell phone while driving?

A. As a general rule, drivers should make every effort to move to a safe place off of the road before using a cell phone. However, in emergency situations a driver must use their judgment regarding the urgency of the situation and the necessity to use a cell phone while driving.

Q. Is NHTSA conducting further research to better quantify the safety impact of using cell phones while driving?

A. NHTSA is conducting research projects on driver cell phone use and will continue to monitor the research of others on this subject. As we learn more about the impact of cell phone use on driver performance and crash risk, and as wireless technologies evolve and expand, NHTSA will make its findings public.

Q. Is talking on a cell phone any worse than having a conversation with someone in the car?

A. Any activity a driver engages while driving has the potential to distract the driver from the primary task of driving. Some research findings comparing cell phone use to passenger conversations while driving, show each to be equally risky, while others show cell phone use to be more risky. A significant difference between the two is the fact that a passenger can monitor the driving situation along with the driver and pause for, or alert the driver to, potential hazards, whereas a person on the other end of the phone line is unaware of the roadway situation.

Q. What do the studies say about the relative risk of cell phone use when compared to other tasks like eating or drinking?

A. The current research does not provide a definitive answer as to which behavior is riskier. In a controlled study, comparing eating and operating a voice-activated cell phone to continuously operating a CD player, it was found that the CD player operation was more distracting than the other activities. In a test track study conducted by NHTSA, the results showed that manual dialing was about as distracting as grooming/eating, but less distracting than reading or changing CDs. It is also important to keep in mind that some activities are carried out more frequently and for longer periods of time and may result in greater risk.
 

Cell Phone Driving Laws

December 2005

Driver cell phone use is largely unrestricted by State laws. No States ban use outright.

Currently, three States and the District of Columbia ban the use of hand-held phones while

driving. One of these bans took effect in 2001 (New York), two in 2004 (New Jersey in May

2004 and DC in July 2004), and one in 2005 (Connecticut). However, Connecticut’s ban took

effect in October, after the 2005 NOPUS was conducted. A small number of States otherwise

restrict the manner of use, e.g., by requiring sound to travel unimpaired to at least one of

the driver’s ears or requiring at least one hand on the steering wheel at all times.

A few States ban use in certain situations, such as when operating a school bus or public transit vehicle. In addition, some major cities have hand-held bans or

otherwise restrict use. Driving while using a headset is even less restricted by traffic laws. No States or major cities ban use outright. As with driver cell phone

use, a small number of States restrict the manner of use, e.g., by requiring sound to travel unimpaired to at least one of the driver’s ears, or

ban certain types of use in certain situations, such as by banning cell phone use (whether hand-held or hands-free) when operating a school

bus or public transit vehicle.
