When you think of in-cab cameras for large trucks, you may think the main benefit would be to keep truck drivers in New Jersey from using cellphones or other electronic devices while behind the wheel. However, the technology has many more applications, and these uses could be just as essential to your safety.
According to Trucking Info, cameras in the cab are not for spying on drivers, although they could act as a deterrent, certainly. Not all systems are the same, but typically they face both inside the truck and outside. Many do not start recording unless there is a near miss, such as if the trucker had to slam on the brakes to avoid rear-ending you, or an actual collision. Some systems can be set to identify traffic infractions such as the running of a red light or failing to wear a seat belt, as well. If you are in a crash with a truck that has cameras rolling, it may be a simple matter to identify liability for the collision, whether due to driver error, truck malfunction or even an unbalanced load.
The camera captures the seconds before and after the event and sends it electronically to specialists who can perform an analysis of the conditions in the cab and on the road at the time of the incident. Maybe the driver did not allow enough following distance between the truck and your car, or perhaps he or she performed an evasive maneuver to counter someone else's mistake and nearly hit you. There could be weather conditions that affect the trucker's control of the tractor-trailer. The trucker's manager would be able to use realtime footage to identify risk factors and provide training, or even to acknowledge the trucker's quick reflexes in avoiding an accident.
