Using cell phone and driving increases risk of accident by how much?

Using a cell phone while driving increases the risk of an accident by approximately four times compared to driving without distractions. Texting while driving can be particularly hazardous, increasing the risk by up to 23 times. This heightened risk is due to the cognitive, visual, and manual distractions that cell phone use creates, significantly impairing a driver's ability to react to road conditions and hazards.
