There are 5,000 truck accident fatalities out of the 500,00 truck accidents every year. Only 2% of those fatalities include truck drivers; the rest are from a smaller vehicle involved in the crashes. And yet, three-quarters of those deadly truck accidents are caused by the smaller vehicle. Those accidents are generally caused by drivers who don't know how difficult it is to change direction or stop a big rig. Any action that cuts off a truck by sudden lane changes, unsafe merging, or improper passing can leave a truck unable to maneuver safely out of the way. On the other hand, truck drivers are more often guilty of fatigue or drowsiness, which can also lead to tragedies on the road. Many truck insurers will be at a deadly truck accident site before the vehicles are cleared. If your loved one has been killed in a truck accident, you need to contact a truck accident lawyer quickly so he can examine the evidence from the site and the truck's black box before it is lost.
