Cellphones and texting are particularly dangerous when driving mainly because they can distract the driver. This distraction can take two critical forms: cognitive and manual. Cognitive distraction occurs when the driver’s attention is diverted from the task of driving to the content of the message, which can significantly impair reaction times and awareness of surroundings. Manual distraction happens when a driver uses their hands to hold the phone or type a message instead of maintaining proper control of the vehicle, leading to a higher risk of accidents.

While increased legal penalties and reduced visibility are certainly relevant concerns when discussing the risks associated with cellphone use while driving, they are not the primary reasons for the heightened danger. The fundamental issue is that distractions take the driver's focus away from driving, which dramatically increases the likelihood of a collision. This is why choosing cellphones and texting as a primary reason for danger emphasizes the critical nature of driver attention and focus.
