The primary cause of driver distraction is the use of mobile phones, an action that involves visual, manual, and cognitive distractions simultaneously, posing a significant threat to driving safety. When using a mobile phone, drivers must divert their eyes from the road to view the screen, remove their hands from the steering wheel to operate the device, while their cognitive attention is occupied by call content or message exchanges. This leads to approximately a threefold delay in reaction time and increases accident risk by 23 times. Other common distractions include operating in-vehicle entertainment systems (accounting for 12% of distraction-related accidents), conversing with passengers (particularly emotional discussions), and manual activities like eating or drinking. From a safety perspective, the human brain automatically reduces focus on individual tasks when multitasking. At a speed of 90 km/h, glancing at a phone for 2 seconds equates to driving blind for 50 meters-a distance sufficient to cause a severe collision. Notably, even hands-free devices cause cognitive distraction, making drivers miss 40% of road environment cues. Thus, the safest practice is to park before handling any communications.
