Abstract

INTRODUCTION:

Although it is becoming more and more accepted that driving while talking on a cell phone can be hazardous, most jurisdictions are making handheld phone use illegal while allowing hands-free phone use.

METHODS:

The scientific literature exploring the effects of these two types of cell phone use on driving and driving-related performance is reviewed here.

RESULTS:

Our review shows that talking on the phone, regardless of phone type, has negative impacts on performance especially in detecting and identifying events. Performance while using a hands-free phone was rarely found to be better than when using a handheld phone. Some studies found that drivers compensate for the deleterious effects of cell phone use when using a handheld phone but neglect to do so when using a hands-free phone.

IMPACT ON INDUSTRY:

Current research does not support the decision to allow hands-free phone use while driving.
