Using a mobile phone constitutes a significant distraction for drivers, making it the most pressing issue to avoid while driving. This activity often requires visual, manual, and cognitive attention, leading to an increased risk of accidents. Research consistently shows that texting or engaging with apps takes a driver's eyes off the road for an extended time and diminishes awareness of surrounding traffic conditions.

When it comes to adjusting the radio, eating, or talking to passengers, while these can also distract drivers, they may not have the same level of impact on driving performance as mobile phone use does. For instance, adjusting the radio might only require a brief glance away from the road, and eating could be managed quickly with practice. However, using a mobile phone often involves sustained engagement, making it a paramount danger that drivers are advised to completely avoid for their safety and the safety of others on the road.
