Read the passage below.
Anything distracting a driver operating a vehicle is potentially dangerous. One such distraction is texting on a cell phone because it requires the driver to look away from the road, even if for just a few seconds. Similarly, talking on one’s cell phone can also cause a distraction because the person is listening to the speaker on the other end and not paying sole attention to the road in front of them. In summary, the best thing to do while driving is to concentrate only on the road.
