There are pros and cons to technological advances. Rear view cameras in cars have helped to increase a driver's ability to monitor his or her surroundings while the vehicle is in reverse, weather satellites have resulted in more warning time for dangerous weather and cellphones have allowed for people to keep in touch with each other no matter where they are. Unfortunately, some take this last advance to the extreme, making calls, sending texts and even checking social media sites while driving. This practice isn't just dangerous, it's illegal. It is not always immediately clear if a driver was engaged in this dangerous and illegal activity prior to involvement in an accident. However, a new device may help to answer this question with a simple and quick scan.
