What is the main effect of distracted driving on reaction time?

Distracted driving primarily affects a driver's reaction time by increasing it, resulting in slower responses to unexpected events on the road. When a driver is distracted—whether by mobile devices, passengers, or other factors—their attention is divided, which hampers their ability to process information quickly. This delay in processing can lead to a failure to react promptly to critical situations, such as sudden stops by other vehicles or pedestrians entering the roadway.

The increased reaction time due to distraction is supported by various studies that show a correlation between distraction and a higher likelihood of accidents. Drivers who are focused and attentive can process multiple stimuli and respond effectively, whereas distracted drivers struggle with this, leading to potential hazards. Therefore, the assertion that distraction increases reaction time accurately reflects its dangerous effects on driving safety.
