Final answer:
The risk of being involved in a collision increases to eight-times normal when a driver is using a cell phone while driving.
Step-by-step explanation:
According to research, the risk of being involved in a collision increases to eight-times normal when a driver is using a cell phone while driving. This is because using a cell phone can distract the driver and take their attention away from the road, increasing the chances of an accident. For example, if a driver is looking down at their phone to read or send a text message, they may not notice a car in front of them stopping suddenly, leading to a collision.
