It is estimated that four semi-trailer truck accident injuries or fatalities occur every hour in this country. That is a lot of damage and injury resulting from a form of transportation that is regulated and should be safe. However, 75% of these accidents are caused by negligence on the part of the passenger cars involved. While semi-trailer truck drivers are trained to know the limitations of these "big rigs," most passenger car drivers are not. That doesn't mean there isn't some negligence on the part of truck drivers. In fact, many are guilty of negligently pushing themselves beyond legal limits and driving while fatigued. If that's the case, your truck accidents lawyers can discover that negligence. They have the skills and the experience to know where to look and to find hidden evidence that you may not be able to locate.
