When is it acceptable to use a cell phone while driving?

Using hands-free technology while driving is permissible because it allows the driver to maintain better control of the vehicle and keeps their focus on the road. Hands-free devices enable drivers to make calls or receive information without needing to hold the phone, significantly reducing the distraction associated with manual phone use. This compliance with safety regulations is vital, as it minimizes the risk of accidents caused by divided attention.

In contrast, the other options describe scenarios that can still lead to distractions. For example, texting quickly involves looking away from the road and can lead to severe distractions. Stopping at a stoplight doesn't eliminate the risk, as drivers may still become absorbed in their phone use, leading to inattention to surrounding traffic. Lastly, having a passenger does not inherently make it safe to use a phone; distractions can still occur regardless of the presence of another person in the vehicle. Thus, the use of hands-free technology stands out as the safest and most responsible way to communicate while driving.
