Summary
Sending voice messages while driving is more distracting than calling and nearly as distracting as texting. Drivers underestimate the risks of voice messaging, necessitating updated safety guidelines and awareness campaigns.
Area of Science:
- Human-computer interaction
- Traffic safety research
- Cognitive psychology
Background:
- Distracted driving is a major public safety concern.
- Existing research primarily focuses on the impact of phone calls and texting while driving.
- The attentional and performance effects of voice messaging while driving remain under-investigated.
Purpose of the Study:
- To compare the driving performance and attentional demands of sending voice messages versus making phone calls and texting.
- To assess the visual and cognitive distraction levels associated with different mobile phone tasks while driving.
- To evaluate driver awareness of the risks associated with voice messaging while operating a vehicle.
Main Methods:
- Participants completed a driving task under four conditions: control, receiving a phone call, sending voice messages, and sending text messages.
- Driving performance was measured using objective metrics.
- Eye tracking and subjective self-report measures were used to assess visual and cognitive distraction.
Main Results:
- Voice messaging while driving resulted in significantly higher visual and cognitive distraction than phone calls.
- While less detrimental than texting, voice messaging showed comparable levels of distraction to texting.
- Drivers demonstrated a lack of awareness regarding the significant risks of voice messaging while driving.
Conclusions:
- Voice messaging poses a substantial distraction risk comparable to texting and greater than calling.
- Current driver awareness and safety guidelines may not adequately address the dangers of voice messaging.
- Further research and targeted public awareness campaigns are needed to highlight the risks of voice messaging while driving.
