Hands-free phone use can actually reduce alcohol-related driving impairment when well-rested, but becomes dangerous when combined with sleep deprivation.

Plain English Summary

Summary written for general audiences

Researchers tested how hands-free cell phone use affects driving ability when combined with alcohol and sleep deprivation. They found that using a hands-free phone while driving actually helped counteract some of alcohol's impairment effects when drivers were well-rested. However, when drivers were severely sleep-deprived (24 hours awake), the combination of alcohol and phone use created the most dangerous driving conditions.

Study Details

The aim of this study is to investigate Effects of prolonged wakefulness combined with alcohol and hands-free cell phone divided attention tasks on simulated driving.

Simulated driving ability was assessed following administration of alcohol, at an estimated blood le...

As expected, subjective sleepiness was highly correlated with both sleep restriction and alcohol con...

Thus apparently 'safe' blood alcohol levels in combination with prolonged wakefulness resulted in significant driving impairments. In normal sleep conditions alcohol effects on driving were partially counteracted by the concomitant hands-free phone based psychometric tasks.
