Are there any studies that demonstrate that talking on a cell phone is more dangerous than any other type of distraction? Yes, it seems clear that talking on a cell phone is a distraction, but for the number of laws passed, I would expect that it be demonstrated that it is more of a distraction (to deserve being singled out legally).
Other common distractions
- Talking to passengers
- Reading (no, I'm not kidding, people do it)
- Applying makeup (also common)
